Anovulation in Wokingham, Berkshire

1. Overview

Anovulation is the failure to release a mature egg from the ovary during a menstrual cycle. Since ovulation is the essential prerequisite for natural conception, anovulation is one of the most common and direct causes of female infertility — accounting for approximately 25–30% of all female infertility cases and found in around 15% of women investigated for difficulty conceiving. Of those with anovulation, approximately 50% will be found to have polycystic ovary syndrome (PCOS), the single most common cause of ovulatory dysfunction.

While conventional medicine offers ovulation induction drugs such as clomiphene citrate and letrozole, these carry risks including ovarian hyperstimulation, increased multiple pregnancy rates, and a thin or unreceptive endometrial lining that can reduce implantation success. Acupuncture and Chinese herbal medicine offer a physiologically gentler approach to restoring natural ovulation, supported by a growing body of clinical research, and work well both as standalone treatments and as adjuncts to conventional ovulation induction.

2. Symptoms

Anovulation does not always announce itself with obvious signs, which is why many women do not know they are not ovulating until they investigate why they have not conceived. Common indicators that ovulation may not be occurring include:

No positive result on ovulation predictor kit (OPK) tests, which detect the LH surge that precedes ovulation
Absence or very little mid-cycle cervical mucus (the clear, stretchy “egg-white” discharge that typically appears at ovulation)
Low progesterone levels on a Day 21 blood test (less than 3 ng/mL is considered indicative of absent or poor ovulation)
Very irregular, infrequent or absent periods — see irregular menstrual cycles and amenorrhoea
Cycles that are consistently shorter than 23 days or longer than 35 days, or that vary widely in length
No rise in basal body temperature (BBT) mid-cycle — a BBT chart typically shows a clear shift of around 0.2°C at ovulation, which is absent in anovulatory cycles
Ultrasound findings showing follicles that develop but do not release (luteinised unruptured follicle syndrome), or multiple small follicles consistent with PCOS

3. Causes

Ovulation depends on the precise, sequential interplay of hormones along the hypothalamic-pituitary-ovarian (HPO) axis. Any disruption to this axis — whether from hormonal, metabolic, structural or functional causes — can prevent ovulation. The most common causes are:

Polycystic ovary syndrome (PCOS) — the leading cause of anovulation in women of reproductive age. In PCOS, elevated androgens and insulin resistance disrupt the normal hormonal signals that drive follicular maturation and the LH surge required for ovulation. Multiple small follicles develop but fail to mature fully and release an egg.
Hypothalamic dysfunction (functional hypothalamic anovulation) — chronic stress, excessive exercise, insufficient caloric intake or significant weight loss suppress GnRH release from the hypothalamus, effectively switching off the hormonal cascade required for ovulation. A minimum body fat level of approximately 22% of body weight is required to maintain normal ovulatory function.
Diminished ovarian reserve — as ovarian reserve declines with age or following certain medical treatments, the response of the ovaries to FSH stimulation weakens. Cycles may become shorter and anovulatory as fewer healthy follicles remain.
Elevated FSH — high FSH levels reflect the pituitary gland working harder to stimulate poorly responsive ovaries. When FSH is very elevated, ovulation often does not occur despite follicular activity.
Hyperprolactinaemia — elevated prolactin, whether from a pituitary adenoma, medications or chronic stress, suppresses the HPO axis and inhibits LH secretion, preventing the mid-cycle LH surge that triggers ovulation.
Thyroid dysfunction — both hypothyroidism and hyperthyroidism can disrupt ovulation. Thyroid hormones directly influence GnRH and gonadotrophin secretion, and thyroid imbalance is one of the more commonly missed causes of anovulatory infertility.
Excessive exercise and very low body weight — the body interprets extreme energy depletion as an environment too hostile to sustain a pregnancy and suppresses reproduction accordingly. Women who exercise intensively — particularly runners, cyclists and athletes in weight-sensitive sports — are at particular risk.
Post-pill anovulation — following cessation of the oral contraceptive pill, the natural HPO axis can take weeks or months to resume normal function. Anovulatory cycles in the period immediately after stopping the pill are common and can persist longer in some women.

4. Diagnosing anovulation

Anovulation is diagnosed through a combination of hormonal blood tests and monitoring:

Day 21 progesterone blood test — measures progesterone seven days after expected ovulation (typically Day 21 in a standard 28-day cycle, or adjusted for longer or shorter cycles). A result above 30 nmol/L (approximately 9.4 ng/mL) confirms ovulation has occurred; a level below 16 nmol/L in a sample taken at the correct time suggests anovulation or poor ovulation. The NHS threshold for referral is typically below 16 nmol/L.
Ovulation predictor kits (OPKs) — detect the LH surge that precedes ovulation by approximately 24–36 hours. A consistently negative OPK throughout the cycle suggests absent ovulation.
Basal body temperature (BBT) charting — a flat BBT chart without the characteristic mid-cycle temperature rise indicates anovulation. See how to tell when you are ovulating for guidance on temperature charting.
Transvaginal ultrasound (follicle tracking) — serial ultrasound scans through the cycle can directly observe whether follicles are growing and releasing. This is the most definitive method and can identify luteinised unruptured follicle syndrome (LUFS), where a follicle fills with fluid and appears to have ovulated but has not actually released the egg.
Hormonal blood panel — FSH, LH, oestradiol, AMH, prolactin and thyroid hormones are routinely measured to identify the underlying cause of anovulation.

5. Anovulation in Chinese medicine

In traditional Chinese medicine (TCM), ovulation is understood as a critical energetic event — the moment when the growing follicle receives sufficient Kidney Yang energy and Blood to complete its maturation and make the sudden Yang surge required to release the egg. This corresponds closely to the biomedical LH surge. For ovulation to occur naturally, the body requires sufficient Kidney Yin and Jing to nourish the developing follicle through the follicular phase, and then adequate Kidney Yang and Liver Qi to drive the release of the egg at the ovulatory moment.

Anovulation in TCM most commonly reflects one or more of the following patterns:

Kidney Yin and Jing deficiency — insufficient Yin and Jing to nourish the follicle to full maturity. The follicle grows but cannot reach the size and hormonal readiness required for ovulation. Associated with a history of overwork, poor sleep, excessive exercise or constitutional depletion, this pattern is frequently seen in women with diminished ovarian reserve or low AMH. Signs include dizziness, night sweats, scanty periods and a fine, rapid pulse.
Kidney Yang deficiency — inadequate Yang energy to drive the critical ovulatory surge, even when the follicle has grown to sufficient size. The follicle fails to rupture and release, corresponding to luteinised unruptured follicle syndrome (LUFS) in biomedical terms. Associated with cold extremities, low back aching, fatigue, a pale complexion and a feeling of internal cold.
Phlegm-Damp obstructing the ovaries — the primary TCM mechanism underlying PCOS-related anovulation. Accumulation of Phlegm-Damp — typically from a combination of poor diet, Spleen Qi deficiency and constitutional tendency — blocks the ovarian follicles and prevents their development and release. Signs include a long or absent cycle, weight gain, a sticky tongue coating and a feeling of heaviness.
Liver Qi stagnation — emotional tension and chronic stress constrain the smooth flow of Liver Qi, which is required to facilitate the Yang surge at ovulation. This is the TCM explanation for stress-related anovulation and is frequently seen in women who are anxious about conceiving. Associated with premenstrual tension, breast tenderness, irritability and an irregular cycle that varies with stress levels.
Blood stagnation — obstructed circulation in the pelvis and ovaries prevents normal follicular development and release. This pattern is often present alongside Liver Qi stagnation and is associated with painful periods, mid-cycle pain and a history of endometriosis or pelvic adhesions.

6. Acupuncture for anovulation

Acupuncture can promote ovulation by normalising the HPO axis, improving ovarian blood flow and follicular responsiveness, reducing the elevated androgens and insulin resistance driving PCOS, and regulating the neuroendocrine environment that drives the critical LH surge. Electroacupuncture in particular has well-documented effects on the sympathetic nervous system outflow to the ovaries and on hypothalamic β-endorphin release, which in turn modulates GnRH secretion and gonadotrophin output.

Research evidence

A landmark study by Stener-Victorin et al. (2000), published in Acta Obstetricia et Gynecologica Scandinavica, found that electro-acupuncture induced regular ovulation in 38% of women with PCOS who had previously been anovulatory, significantly improving hormonal profiles including reduced testosterone and LH/FSH ratios. A systematic review and meta-analysis by Gao et al. (2020), published in Acupuncture in Medicine, analysed 9 RCTs including 1,441 women with anovulatory infertility and found that acupuncture used as a standalone treatment significantly improved both pregnancy rate and maximum follicular diameter compared with clomiphene citrate alone, and also significantly reduced the rate of pregnancy loss when used as a monotherapy. A systematic review and meta-analysis by Wu et al. (2020) of 22 RCTs with 2,315 participants found that acupuncture promoted the recovery of the menstrual period and significantly reduced LH and testosterone levels in women with PCOS, supporting its role in restoring ovulatory function. A network meta-analysis by Yang et al. (2023), published in Frontiers in Endocrinology, covering 6 RCTs with 1,410 PCOS patients, found that combining acupuncture and moxibustion with clomiphene was superior to clomiphene alone for ovulation induction and pregnancy outcomes. A 2024 systematic review and meta-analysis by Liang et al. of 20 RCTs with 1,677 patients with ovulatory disorder infertility found that acupuncture combined with clomiphene significantly improved pregnancy rate (RR 1.68) and ovulation rate (RR 1.34) compared with clomiphene alone, while also improving endometrial thickness and reducing miscarriage rate.

The approach to acupuncture treatment for anovulation uses the TCM “artificial cycle” methodology — selecting acupuncture points and stimulation techniques appropriate to each phase of the menstrual month to progressively support follicular development and create the conditions for a spontaneous ovulatory event. Treatment typically involves weekly sessions timed across the follicular and peri-ovulatory phases.

7. Chinese herbal medicine for anovulation

Chinese herbal medicine complements acupuncture effectively for anovulation, providing a daily therapeutic stimulus that supports follicular development, hormonal regulation and the energetic conditions needed for ovulation between acupuncture sessions. The research base for TCM — including Chinese herbal medicine — for ovulatory disorder infertility has grown substantially in recent years, with systematic reviews and meta-analyses confirming significant benefits for ovulation rates and pregnancy outcomes.

Classical herbal formulas are selected according to the specific TCM pattern identified at consultation. For Kidney Yin deficiency, Zuo Gui Wan or Gui Shao Di Huang Wan nourish Kidney Yin and Blood to support follicular maturation through the follicular phase. For Kidney Yang deficiency and LUFS, You Gui Wan and Wu Zi Yan Zong Wan tonify Yang and warm the uterus to facilitate the ovulatory surge. For PCOS-related Phlegm-Damp obstruction, Cang Fu Dao Tan Tang resolves Phlegm and activates the follicles, and is typically combined with Kidney Yang tonics to drive ovulation once follicles begin to mature. For Liver Qi stagnation, Xiao Yao San promotes the free flow of Qi and Blood and is often prescribed in the peri-ovulatory phase to facilitate egg release.

I prescribe pharmaceutical-grade Chinese herbal granules from Sun Ten (Taiwan), independently tested for purity and safety. For patients who cannot attend the clinic in person, I offer online Chinese herbal medicine consultations with herbs dispensed by post.

8. Self-care

Restoring regular ovulation often requires addressing the lifestyle factors that are suppressing it, alongside TCM treatment. Key self-care recommendations include:

Achieving and maintaining a healthy weight — both low body weight and excess weight disrupt ovulation. A minimum body fat level of approximately 22% of body weight is required for normal ovulatory function. In PCOS, even a modest 5–10% reduction in body weight in overweight women can restore regular ovulation.
Reducing excessive exercise — high-volume or high-intensity training can suppress the HPO axis and prevent ovulation. Reducing the frequency and intensity of exercise — particularly for women training more than four or five times per week — allows the body to restore its hormonal balance. This is one of the most direct and impactful lifestyle changes for exercise-induced anovulation.
Adequate and regular nutrition — the body requires sufficient carbohydrate, fat and protein to support ovarian function. Restrictive diets, particularly very low calorie or very low carbohydrate approaches, can suppress ovulation within weeks. Regular, nourishing meals support the Spleen and Kidney function that underpins ovulation in TCM.
Reducing stress — chronic stress suppresses GnRH release and inhibits the LH surge required for ovulation. Stress management practices — including mindfulness, tai chi, yoga and regular relaxation — directly support the HPO axis.
Tracking ovulation — using ovulation predictor kits, BBT charting and cervical mucus observation helps identify whether ovulation is returning and when you are ovulating, which is critical for timing conception attempts.
Improving sleep — adequate sleep supports Kidney Yin and Jing in TCM, both of which are fundamental to follicular development and ovulation. Consistently sleeping before midnight, for seven to eight hours, supports hormonal recovery.

9. Treatment at my clinic

I treat anovulation and ovulatory disorder infertility at my clinics in Wokingham, Berkshire. I also offer online Chinese herbal medicine consultations for patients who cannot attend in person.

Treatment uses the TCM artificial cycle approach, combining acupuncture and Chinese herbal medicine with phase-specific prescribing tailored to each stage of the cycle as it begins to re-establish. Treatment works well both on its own and alongside conventional ovulation induction medication, improving the endometrial environment and reducing the side effects of clomiphene while further supporting ovulatory success. For women with PCOS, treatment addresses the underlying insulin resistance and androgen excess driving anovulation, not just the ovulatory event itself. Recovery of regular ovulation typically takes two to four months of consistent treatment combined with appropriate lifestyle changes.

10. Frequently asked questions

Can acupuncture help me ovulate?

Yes. Acupuncture can promote ovulation by normalising the HPO axis, improving ovarian blood flow, reducing androgens and insulin resistance in PCOS, and supporting the LH surge required to trigger egg release. Research confirms that electroacupuncture induced regular ovulation in 38% of previously anovulatory women with PCOS, and that acupuncture as a monotherapy significantly improved pregnancy rates compared with clomiphene citrate alone in women with anovulatory infertility.

How many sessions of acupuncture are needed to restore ovulation?

Most patients with functional anovulation begin to show signs of returning ovulatory activity within six to twelve weekly sessions. Using the TCM artificial cycle approach — timing sessions to specific phases of the month — combined with Chinese herbal medicine and appropriate lifestyle changes, most women with functional anovulation restore regular ovulation within two to four months.

Can acupuncture be used alongside clomiphene or letrozole?

Yes. Acupuncture is safe and effective when used alongside conventional ovulation induction medication. Research confirms that combining acupuncture with clomiphene significantly improves both ovulation rates and pregnancy rates compared with clomiphene alone, while also improving endometrial thickness — a critical factor for successful implantation that clomiphene can actually reduce. Acupuncture can also help manage the side effects of clomiphene, including headaches, hot flushes and mood changes.

What is the best acupuncture approach for PCOS-related anovulation?

Electroacupuncture has particularly strong evidence for reducing the androgens and insulin resistance that drive anovulation in PCOS. Combined with Chinese herbal formulas that resolve Phlegm-Damp and tonify Kidney Yang, and dietary and lifestyle modification to reduce insulin resistance, this represents the most comprehensive TCM approach to restoring ovulation in PCOS.

How is anovulation different from irregular ovulation?

Anovulation means the ovary fails to release an egg at all in a given cycle. Irregular ovulation means that ovulation does occur but inconsistently — either too early, too late or with variable timing that makes it difficult to time conception attempts. Both are treated with the same TCM approach of regulating the HPO axis and addressing the underlying pattern of imbalance, though irregular ovulation typically responds more quickly than complete anovulation.

Can I get pregnant if I have anovulation?

Natural conception is not possible in the absence of ovulation. However, this does not mean that pregnancy is impossible — it means that restoring ovulation is the essential first step. With the right treatment — whether through acupuncture, Chinese herbal medicine, lifestyle changes, or a combination of these with conventional medication — many women with anovulation go on to ovulate regularly and conceive naturally.
