Lower back pain is something most of us will experience at some point – studies suggest it affects around 90% of people during their lifetime. We usually put it down to a strain, an old injury, or too many hours hunched over a desk. But in my clinical experience, and in Traditional Chinese Medicine (TCM) more broadly, lower back pain – particularly around the menstrual cycle – can sometimes point to something deeper: a possible link with fertility.
The Kidney connection in TCM
In TCM, the Kidney (肾, shèn) is about much more than urinary function. It’s considered the root of the body’s reproductive and developmental energy, storing what’s known as Kidney essence (肾精, shèn jīng). When Kidney function is strong, reproductive health tends to follow. When Kidney essence is depleted – a pattern we describe as Kidney Deficiency (肾虚, shèn xū) – it may correspond with fertility challenges in some patients.
The lower back is considered the “house of the Kidneys” in TCM theory, which is part of why persistent lower back pain – especially pain that flares before or during menstruation – is something I pay close attention to in a fertility consultation. It doesn’t mean a diagnosis on its own, but it can be a useful clue when we’re building a fuller picture of someone’s reproductive health.
How I approach it in the clinic
When a patient presents with lower back pain alongside fertility concerns, my approach usually involves acupuncture and Chinese herbal medicine, tailored to the individual’s presentation. This applies whether someone is trying to conceive naturally or alongside IVF. Depending on the pattern involved, treatment may aim to:
Support Kidney Qi – the vital energy associated with Kidney function
Warm Kidney Yang – where a pattern of coldness or low energy is present
Nourish Kidney Yin – where signs of depletion or dryness are present
Improve Qi and Blood flow – where a pattern of Qi and Blood stagnation (气血瘀滞, qì xuè yū zhì) is contributing to pain or poor circulation to the reproductive organs
At Almond Wellness Centre, treatment plans are personalised rather than one-size-fits-all. Alongside acupuncture and herbal medicine, we often incorporate dietary and lifestyle guidance, since these can also influence Kidney function and overall reproductive health.
When to seek support
If you’ve noticed lower back pain that seems connected to your menstrual cycle, or you’re navigating fertility challenges and wondering whether there’s more going on beneath the surface, it may be worth having a conversation with a qualified practitioner. Our women’s health acupuncture service takes this kind of full-picture approach, and a proper assessment can help clarify whether TCM-based support is appropriate for your situation, alongside any care you’re already receiving.

Polycystic ovary syndrome (PCOS) is one of the most common reasons women come to see me at the clinic, whether they’re dealing with irregular periods, absent ovulation, trying to conceive, or managing the metabolic side of PCOS. It’s also a condition I get asked about constantly:
does acupuncture actually do anything for PCOS, or is it just wishful thinking?
A narrative review published this month in the International Journal of Women’s Health (July 2026) took a close look at exactly this question. Rather than cherry-picking studies that support acupuncture, the authors set out to sort the evidence by how direct and reliable it actually is — separating solid human clinical data from promising animal research, and animal research from studies on completely different conditions being used to fill in the gaps. I think that kind of honesty is rare in this space, and it’s worth walking you through what they found.
PCOS is more than an ovary problem
Before getting to acupuncture, it’s worth understanding why PCOS is so stubborn to treat. The review frames it as a whole-system issue – what researchers call a neuroendocrine-immune network problem – rather than something happening in isolation in the ovaries.
In PCOS, the signalling between the brain and the ovaries (the hypothalamic-pituitary-ovarian axis) tends to run too fast, pushing luteinising hormone (LH) up and leaving follicle-stimulating hormone (FSH) relatively low. That imbalance interferes with follicles developing properly and pushes androgen production up, which then feeds back and speeds the whole cycle up again. Layered on top of that, many women with PCOS also have an overactive sympathetic nervous system (the “fight or flight” side), low-grade chronic inflammation, and insulin resistance – and all three tend to reinforce each other. It’s a genuinely tangled picture, which is part of why no single treatment, acupuncture included, is likely to be a silver bullet.
In TCM terms, this cluster of imbalance and stagnation is often connected to patterns like Phlegm-Damp (痰湿, tán shī) or Kidney deficiency (肾虚, shèn xū) — different language for a similar idea, that the body’s regulatory systems have gotten out of sync.
Here’s a simplified picture of how these pieces feed into one another:
Where the evidence for acupuncture is strongest
The review is refreshingly specific about which effects are backed by solid human trials and which are still hopeful extrapolation from animal studies. Two areas stood out as having the most direct clinical support:
Sympathetic nervous system activity
A randomised controlled trial found that low-frequency electroacupuncture over 16 weeks meaningfully reduced sympathetic nerve activity in women with PCOS, with results comparable to a structured aerobic exercise program. Since sympathetic overactivity is thought to be one of the drivers of PCOS, calming this system down is a genuinely encouraging finding.
Insulin resistance
Several human trials, including a three-arm randomised study comparing acupuncture with metformin, found modest improvements in insulin sensitivity markers (like HOMA-IR) after a course of acupuncture. Given how tightly insulin resistance is linked to androgen excess and ovulatory problems in PCOS, this is a meaningful area of support — though the review is careful to note the effect sizes vary a lot between studies and aren’t as strong or consistent as a first-line medication.
One interesting point from the review is that many of the stronger clinical studies used low-frequency electroacupuncture rather than manual acupuncture alone. Electroacupuncture involves attaching a gentle electrical current to acupuncture needles after insertion, providing consistent stimulation throughout the session. This doesn’t mean manual acupuncture is ineffective, but it does mean the results of these studies may not always translate directly to every acupuncture protocol used in clinical practice – it’s worth asking your practitioner which approach they’re using and why.
Where the picture is more promising than proven
This is the part I appreciate most about the review: it doesn’t pretend the exciting mechanistic story is the same as clinical proof.
A lot of the more detailed explanations you’ll read about how acupuncture might help PCOS – things like rebalancing immune cells in the ovary, correcting the “window of implantation” in the uterine lining, or reprogramming inflammatory pathways at a cellular level – come almost entirely from studies in rats and mice, or from research on completely different conditions like general implantation failure. These are legitimate and interesting research directions, but they’re not the same as evidence that acupuncture does these things in real women with PCOS. The review is explicit that human data confirming these deeper immune mechanisms is largely absent.
On the reproductive outcomes that matter most to patients – actual pregnancy, ongoing pregnancy, and live birth – the evidence is genuinely mixed. One large multicentre trial did not find that acupuncture improved live birth rates when added to standard fertility care. A smaller study on IVF embryo transfer reported better embryo quality and live birth rates, but this hasn’t been consistently reproduced elsewhere, so it should be read as an interesting early signal rather than a proven benefit.
What this means if you’re considering acupuncture for PCOS
When performed by an AHPRA-registered practitioner using sterile, single-use needles, acupuncture is generally considered safe and is commonly used alongside conventional fertility care.
If you’re navigating PCOS, here’s how I’d summarise where things stand:
Acupuncture is not a substitute for guideline-based PCOS care – lifestyle management, and where appropriate, pharmacological or fertility treatment recommended by your GP, endocrinologist, or fertility specialist.
There’s reasonably good evidence that acupuncture, particularly electroacupuncture, may help calm an overactive sympathetic nervous system and support insulin sensitivity – two of the underlying drivers of PCOS.
Evidence for improving menstrual regularity and ovulation remains encouraging but inconsistent across studies, with differences in treatment protocols and study quality making firm conclusions difficult.
Claims about acupuncture “fixing” implantation or fertility outcomes at a cellular level are not yet supported by strong human evidence, however plausible they may sound.
What I find most useful about this kind of research isn’t a green light or a red light – it’s a map. It tells us acupuncture is a reasonable adjunct worth discussing as part of a broader PCOS management plan, and it tells us where the honest gaps are so nobody’s oversold on what a course of treatment can do.
No. PCOS is a chronic condition with no single cure, and acupuncture is best considered a possible adjunct to lifestyle changes and conventional medical care, not a replacement for them.
Does acupuncture help with PCOS-related weight gain and insulin resistance?
Some clinical trials have shown modest improvements in insulin sensitivity markers with acupuncture, though results vary between studies and individuals.
How long does it take to see results from acupuncture for PCOS?
Studies referenced in the review used courses of treatment lasting around 16 weeks, though individual response varies and should be discussed with your practitioner.
Should I stop my PCOS medication if I start acupuncture?
No – please don’t change or stop any prescribed medication without speaking to your GP or specialist first. Acupuncture is generally considered as an adjunct, not a replacement, for evidence-based PCOS treatment.

You stopped the pill a few months ago, expecting your period to return fairly quickly.
But weeks have passed. Then months.
Now you’re wondering:
“Is this normal?”
“Did the pill damage my fertility?”
“Should I be worried?”
These are some of the most common questions we hear at Almond Wellness Centre.
The good news is that in most cases, post-pill amenorrhea is temporary and does not mean you have become infertile. However, if your period hasn’t returned after several months, it’s also important not to ignore it.
Understanding the difference between a normal adjustment period and an underlying hormonal issue is the key.
What Is Post-Pill Amenorrhea?
Post-pill amenorrhea refers to the absence of menstruation for three months or longer after stopping oral contraceptive pills.
It is a type of secondary amenorrhea, meaning periods have stopped after previously occurring.
One thing many women are never told is that the monthly bleeding experienced while taking the pill is not a true menstrual period. It is a withdrawal bleed caused by a temporary drop in synthetic hormones.
Because of this, regular bleeding while on the pill doesn’t necessarily tell us whether natural ovulation was occurring underneath.
When the pill is stopped, your body’s own hormonal cycle has to take over again.
For most women, it does.
For some, it takes longer than expected.
How Common Is It?
Short-term cycle irregularity after stopping the pill is actually quite common.
Research suggests that many women experience temporary delays or irregular cycles during the first one to two months after discontinuing oral contraceptives.
True post-pill amenorrhea, where periods do not return for three months or more, is estimated to affect approximately 1-3% of women after stopping the pill.
Although that percentage sounds small, it represents a significant number of women looking for answers about why their cycle has not resumed.
Why Doesn’t My Period Come Back Immediately?
While you’re taking the pill, your body’s reproductive hormone system is largely placed on pause.
The pill suppresses ovulation by influencing communication between:
The hypothalamus
The pituitary gland
The ovaries
Together, these form what doctors call the Hypothalamic-Pituitary-Ovarian (HPO) Axis.
After stopping the pill, this hormonal communication network must restart.
The hypothalamus begins releasing GnRH again, the pituitary produces FSH and LH, and the ovaries gradually resume ovulation.
For most women this process takes between four and eight weeks.
For others, it simply takes longer.
This delay alone is not necessarily a sign that something is wrong.
The Most Important Thing Most Women Aren’t Told
In many cases, the pill isn’t causing the problem.
It’s revealing a problem that was already there.
Many women originally started the pill because they had:
Irregular periods
Painful periods
Acne
Suspected PCOS
Heavy bleeding
While on the pill, these issues may appear to disappear because the medication creates an artificial cycle.
When the pill is stopped, the original pattern often returns.
This is known as the “unmasking effect.”
In other words, the pill may have been hiding an underlying condition rather than causing a new one.
Conditions That May Become Apparent After Stopping the Pill
Polycystic Ovary Syndrome (PCOS)
PCOS is one of the most common reasons periods fail to return after stopping oral contraceptives.
Many women are diagnosed only after discontinuing the pill and noticing absent or highly irregular cycles.
Hypothalamic Amenorrhea
This occurs when the brain temporarily suppresses reproductive function due to:
Chronic stress
Under-eating
Significant weight loss
Excessive exercise
The body essentially decides that conditions are not ideal for reproduction.
Thyroid Disorders
Both underactive and overactive thyroid conditions can interfere with ovulation and menstrual cycles.
Elevated Prolactin
High prolactin levels can suppress ovulation and prevent regular periods from occurring.
Premature Ovarian Insufficiency (POI)
Although less common, POI should be considered, especially in women over 35 experiencing symptoms such as:
Hot flushes
Night sweats
Vaginal dryness
Reduced ovarian reserve
Most women with post-pill amenorrhea do not have these conditions.
However, they are important reasons why prolonged absence of periods deserves investigation.
When Should You Seek Medical Advice?
First 6 Weeks
No period is generally considered normal.
At this stage, your body is still adjusting.
If pregnancy is possible, take a pregnancy test.
2-3 Months
Many women are still within a normal adjustment window.
Monitoring is appropriate.
Around 3 Months
If your period has not returned, it is reasonable to speak with your GP and discuss whether further assessment is needed.
Around 6 Months
If periods have still not returned after six months, formal investigation is strongly recommended.
At this stage, it is important to identify any underlying cause.
A pelvic ultrasound may also help assess ovarian appearance and endometrial thickness.
These investigations can help identify conditions such as PCOS, thyroid dysfunction, hypothalamic amenorrhea, or premature ovarian insufficiency.
A Traditional Chinese Medicine Perspective
In Traditional Chinese Medicine (TCM), healthy menstruation depends on the smooth flow of Qi and Blood through the Chong Mai and Ren Mai channels, which help regulate reproductive function.
When women present with post-pill amenorrhea, several patterns commonly emerge.
Kidney Yang Deficiency
Often associated with:
Fatigue
Feeling cold
Low motivation
Reduced libido
Blood and Kidney Deficiency
Often seen in women with:
Light periods
Pale complexion
Dizziness
Dry skin
Liver Qi Stagnation
Frequently linked to:
Stress
Emotional tension
Anxiety
Hypothalamic amenorrhea
At Almond Wellness Centre, treatment is always individualised.
Acupuncture and Chinese herbal medicine are selected based on the specific pattern present rather than applying the same treatment to every woman.
Importantly, Chinese medicine should complement appropriate medical assessment, not replace it.
Research suggests acupuncture may support reproductive health by influencing the nervous and endocrine systems, improving blood flow to the reproductive organs, and reducing stress.
A study by Paulus et al. found improved pregnancy rates when acupuncture was used alongside assisted reproductive treatments. Another study by Hullender Rubin and colleagues reported improved IVF outcomes using a whole-systems Traditional Chinese Medicine approach.
While acupuncture is not a guaranteed solution, many women find it a helpful part of a broader plan to restore cycle regularity and support reproductive health.¹²
Frequently Asked Questions
Can the pill permanently affect fertility?
Current evidence does not support this.
Studies consistently show that fertility returns to normal after stopping oral contraceptives, although some women may experience a temporary delay before cycles resume.
How long does it usually take for periods to return?
Most women resume menstruation within four to eight weeks.
The vast majority have resumed cycling by three months.
A sustained temperature rise after mid-cycle often indicates ovulation has occurred, even before periods become regular.
When to Seek Support
If your period has not returned three months after stopping the pill, don’t panic – but don’t ignore it either.
The most helpful next step is often a conversation with your GP and appropriate testing.
If no clear cause is found, or if you’re looking for additional support alongside conventional care, acupuncture and Traditional Chinese Medicine may help support your body’s return to a healthy cycle.

If you’ve recently had an AMH blood test and found yourself staring at a number with no idea what to make of it, you’re not alone.
Every week in my clinic, I see women holding a pathology report with an AMH result that has set off a wave of anxiety – often without much explanation from whoever ordered the test. The number sits there looking definitive. It rarely comes with context.
So let me give you that context.
What is AMH?
AMH stands for Anti-Müllerian Hormone. It’s produced by small follicles in your ovaries – the tiny fluid-filled sacs that each contain an immature egg. The more follicles you have actively developing at any given time, the higher your AMH level will be.
In simple terms: AMH is a marker of your ovarian reserve – the pool of eggs remaining in your ovaries.
Unlike other fertility hormones such as FSH or oestradiol, AMH levels stay relatively stable across your menstrual cycle. You can have the test done on any day without timing it to a particular cycle phase. That consistency is one of the reasons it has become a widely used fertility screening tool.
AMH levels by age: a reference guide
AMH naturally declines with age. This is completely expected – it’s how reproductive biology works. The question isn’t just what your number is, but what it means for your age.
Most Australian pathology reports list AMH in either ng/mL (nanograms per millilitre) or pmol/L (picomoles per litre). If you need to convert between the two: 1 ng/mL ≈ 7.14 pmol/L.
Approximate age-adjusted AMH reference ranges:
Age
ng/mL
pmol/L
Under 30
2.0 – 6.8
14 – 49
30–34
1.2 – 5.8
9 – 41
35–37
0.7 – 3.5
5 – 25
38–40
0.3 – 2.8
2 – 20
41–43
0.1 – 2.5
1 – 18
Over 43
0.1 – 1.5
1 – 11
These are approximate reference ranges. Specific values differ between laboratory assays and should always be interpreted by your doctor alongside your full clinical picture.
A result below the expected range for your age may prompt your doctor to describe it as “low AMH” or “diminished ovarian reserve.” A result above the upper range may indicate a high follicle count, which can be associated with PCOS, and has its own clinical considerations.
What low AMH actually tells you
Low AMH tells you one specific thing: that your measurable pool of developing follicles is smaller than expected for your age.
What it doesn’t tell you is anything definitive about:
Egg quality. AMH reflects quantity, not quality. You can have low AMH and excellent egg quality. You can have high AMH and poor quality. The two don’t map neatly onto each other.
Your ability to conceive. Many women with low AMH conceive naturally or through IVF. A low number makes the path more complex – it doesn’t close the door.
How long you’ve been this way. AMH is a snapshot taken at one moment in time. There’s no way to know from a single reading whether your levels have been declining rapidly or have been stable for years.
Why your reserve is low. Low AMH has many possible causes – autoimmune conditions, previous ovarian surgery, endometriosis, genetics, or simply a naturally smaller starting reserve. These distinctions matter for how you approach the situation.
I say this not to offer false reassurance, but because a number out of context causes a particular kind of distress. The full picture is almost always more nuanced than a single result conveys.
What the AMH test doesn’t measure
This is something I feel strongly about explaining, because I think it gets glossed over.
AMH is a useful screening marker. It is not a complete fertility assessment.
It doesn’t measure:
Whether you’re ovulating
The quality of your endometrial lining
Whether your fallopian tubes are open
Your partner’s sperm health
The hormonal environment your eggs are maturing in
Fertility involves many variables. AMH is one. It’s worth knowing – but it’s rarely the only thing that matters.
The Chinese medicine perspective on ovarian reserve
In Traditional Chinese Medicine, we don’t have a direct equivalent to AMH – it wasn’t part of the classical framework. But there is a concept that maps closely to what AMH is measuring: Kidney Jing (精).
Kidney Jing is the inherited constitutional essence that supports reproductive vitality. It is finite, and it naturally declines over time – much as AMH does. But it can be nourished, supported, and protected through acupuncture, herbal medicine, and lifestyle.
When I assess a patient with low AMH, I’m not looking at the number in isolation. I’m looking at:
Which underlying pattern is present – Kidney Yang deficiency, Kidney Yin deficiency, Blood deficiency, Liver Qi stagnation, or a combination
How the menstrual cycle looks as a whole – regularity, flow, colour, consistency
Energy levels, sleep, temperature regulation, and other signs of overall vitality
Treatment aims to support ovarian environment, improve circulation to the reproductive organs, and regulate the hormonal conditions in which eggs mature.
I want to be clear about what this means clinically: we are not claiming that acupuncture or herbal medicine can directly raise an AMH number. What we work toward is improving the broader physiological environment – circulation, hormonal regulation, and systemic resilience – in a way that may support reproductive health and IVF outcomes.
A single AMH result tells an incomplete story. Ask your GP or fertility specialist to also test FSH, LH, oestradiol, and antral follicle count (AFC) via ultrasound. Together, these give a far clearer view of where things stand.
2. Understand your timeline
If you’re not actively trying to conceive right now, knowing your AMH level allows you to plan. If you are trying, it can help you and your fertility specialist decide on the right approach – timed natural conception, ovarian stimulation, or IVF.
3. Consider the 90-day window
Egg development takes approximately 90-120 days from early follicle recruitment to ovulation. This is the window in which supportive treatment – whether acupuncture, herbal medicine, or lifestyle change – may have the most potential influence. Starting early matters more than starting perfectly.
Smoking, alcohol, a highly inflammatory diet, chronic sleep disruption, and unmanaged stress all affect the environment your eggs are maturing in. These factors won’t override genetics, but they are modifiable – and they matter.
Frequently asked questions
Can AMH levels improve?
AMH levels are significantly influenced by genetics and generally decline with age.
Some research suggests that certain lifestyle interventions and treatment protocols may be associated with modest improvements in antral follicle count and related hormonal markers – though this is an active area of research and we are careful not to make definitive claims about directly raising AMH.
What we do see, clinically, is that many patients who support their overall reproductive health report improvements in how they feel and, in some cases, in related markers over time.
What is considered a critically low AMH level?
Results below approximately 0.5 ng/mL (3.5 pmol/L) are often described as severely diminished ovarian reserve.
Results below 0.16 ng/mL (1.0 pmol/L) may be considered very low or near-undetectable. At these levels, a fertility specialist will typically recommend discussing IVF relatively soon, given the potential for continued natural decline.
AMH reflects the quantity of developing follicles, not the presence or absence of ovulation. Women with low AMH may still ovulate regularly and conceive naturally. The primary concern is the reduced time margin – a smaller reserve means less room for delay – and the potential for a lower IVF response if assisted conception becomes necessary.
Is AMH the same as ovarian reserve?
AMH is one marker of ovarian reserve, not the whole picture.
Antral follicle count (AFC) on ultrasound and FSH are also used. No single marker fully captures ovarian reserve, which is why clinicians typically interpret these together rather than acting on any one result alone.
How often should I retest?
There is no universal guideline.
If you have had a low or borderline result, retesting after 6 – 12 months can help assess rate of change. Results can also vary between laboratory assays, so if your result seems unexpected, retesting at the same lab provides a more useful comparison.

One of the first questions I ask women who are trying to conceive is:
“Have you had your Vitamin D levels checked recently?”
The answer is often something like:
“I thought Vitamin D was only important for bones.”
That used to be the general view. But today, we know Vitamin D plays a much bigger role in overall health – including fertility.
In recent years, Vitamin D has become one of the most studied nutrients in reproductive medicine. A large 2025 systematic review and dose-response meta-analysis of more than 15,000 women provides some of the strongest evidence yet that Vitamin D status may influence fertility outcomes.¹
So what does this actually mean if you’re trying to get pregnant?
Why Vitamin D Matters for Fertility
Vitamin D is often called a vitamin, but it actually acts more like a hormone in the body.
Researchers have found Vitamin D receptors throughout the female reproductive system, including the ovaries, uterus, and endometrium (the uterine lining). This suggests that Vitamin D may influence several key aspects of fertility.
Ovarian Function
Vitamin D appears to help regulate hormones involved in egg development and ovarian reserve, including Anti-Müllerian Hormone (AMH) and Follicle Stimulating Hormone (FSH).
These hormones play important roles in egg quantity and quality.
Endometrial Receptivity
For pregnancy to occur, an embryo must successfully implant into the uterine lining.
Vitamin D helps regulate genes involved in endometrial receptivity, including HOXA10, which supports implantation and early pregnancy development.
Protection of Developing Eggs
Vitamin D has also been found in follicular fluid, the fluid surrounding developing eggs inside the ovary.
Research suggests it may help reduce oxidative stress, which can negatively affect egg quality.
This doesn’t mean Vitamin D is a miracle fertility treatment. However, it does suggest that low levels could potentially make conception more difficult.
What the Research Found
Earlier studies on Vitamin D and fertility were mixed. Some showed benefits, others showed no clear link.
This 2025 meta-analysis is important because it combined a large number of studies and examined dose-response effects — not just whether Vitamin D matters, but how much is enough.¹
Low Vitamin D = Lower Pregnancy Rates
Women with levels below 20 ng/mL had significantly lower clinical pregnancy rates compared with those above this level.
Higher Levels = Better Live Birth Rates
Women with Vitamin D levels ≥30 ng/mL had higher live birth rates compared to those who were deficient or insufficient.
A Possible Threshold Around 24 ng/mL (60 nmol/L)
Outcomes tended to become less favourable when Vitamin D dropped below ~24 ng/mL.
Above this level, results appeared more stable and generally improved with higher Vitamin D levels.
What Should You Do?
A simple blood test (25(OH)D) will tell you your status.
This is especially important if you:
Common
Easy to test
Simple to correct
So it’s a very reasonable part of preconception care.
1. Get Your Levels Checked
A simple blood test measuring serum 25(OH)D can tell you whether your Vitamin D levels are adequate.
Testing is particularly important if you:
Spend most of your time indoors
Live in southern Australia, especially during winter
Have darker skin
Carry excess body weight
Regularly use sun protection
2. Know Your Target
Based on current evidence:
Minimum: ~24 ng/mL (60 nmol/L)
Optimal range: ≥30 ng/mL (75 nmol/L)
3. Supplement If Necessary
If levels are low, Vitamin D3 (cholecalciferol) is usually recommended.
Typical maintenance doses range:
2,000–4,000 IU daily
Higher doses may be needed if deficiency is significant (under supervision).
Recheck levels after 8–12 weeks.
4. Don’t Depend on Sunshine Alone
Living in Melbourne makes consistent Vitamin D from sunlight difficult for many people – especially those working indoors.
Diet (oily fish, eggs, fortified foods) helps, but is rarely enough to correct deficiency alone.
The Bigger Picture
Vitamin D is just one piece of the fertility puzzle.
It will not overcome:
Poor egg quality
Blocked tubes
Endometriosis
Male factor infertility
But it may help remove one small, modifiable barrier.
How Traditional Chinese Medicine Fits In
At Almond Wellness Centre, we combine both modern reproductive science and Traditional Chinese Medicine (TCM).
Alongside nutritional and blood test insights like Vitamin D, acupuncture and herbal medicine may support:
Menstrual regularity
Ovarian function
Uterine blood flow
Stress regulation
IVF preparation
Together, this can help create a more supportive environment for conception.
