Infertility is defined as the inability to achieve pregnancy after 12 months of regular unprotected sexual intercourse (6 months for women over 35). It affects approximately 1 in 7 couples in the UK and can arise from female factors (ovulatory dysfunction — most commonly PCOS, premature ovarian insufficiency, endometriosis, blocked fallopian tubes from prior infection), male factors (impaired sperm quality — the cause in approximately 40% of couples), or combined factors. Lifestyle contributors to infertility include smoking, excessive alcohol, obesity, extreme exercise, nutritional deficiencies, and chronic stress. Age is a significant factor in female fertility. Holistic approaches support hormonal regulation, sperm and egg quality through nutritional optimisation, stress reduction, and addressing underlying conditions, alongside appropriate reproductive medicine assessment.
The Evidence
What research and clinical practice tell us about infertility, its causes, and the range of approaches that may support reproductive health.
Infertility is well-studied, with multiple evidence-backed pathways
Infertility is common, affecting a significant proportion of couples worldwide. Causes span both partners, and a range of conventional and supportive approaches exist — early specialist assessment is important.
Sudden pelvic pain with infertility may indicate a structural emergency. Signs of premature ovarian insufficiency in younger women, or hormonal symptoms such as galactorrhoea or virilisation, warrant prompt specialist review. Delaying investigation beyond 12 months (or 6 months if over 35) narrows the window for investigation and care.
Ovulatory disorders, tubal pathology, endometriosis, and male factor infertility are well-characterised causes. Assisted reproductive technologies including IVF and IUI have robust evidence for efficacy. Lifestyle factors — smoking, alcohol, obesity, and nutritional status — are also well-supported contributors to fertility outcomes.
A GP or reproductive specialist can arrange hormonal profiling, semen analysis, pelvic imaging, and referral to fertility services where appropriate. Both partners should be assessed. Complementary approaches may be considered alongside — not instead of — professional reproductive medicine assessment.
Nutritional optimisation, stress reduction, and addressing underlying conditions such as thyroid dysfunction or PCOS may support fertility outcomes. Acupuncture as an adjunct to assisted reproduction has mixed but growing evidence. Avoid self-selecting fertility supplements without appropriate testing, as some carry risks in certain hormonal contexts.
Ayurvedic practice uses shatavari specifically to support ovulatory function and uterine receptivity, and ashwagandha to address stress-related hormonal disruption. TCM maps certain fertility presentations — including irregular cycles and poor ovarian reserve — to kidney-jing deficiency, guiding acupuncture and herbal protocols accordingly. These frameworks offer complementary perspectives but should not replace evidence-based reproductive assessment.
Acupuncture as an adjunct to ART shows mixed results across trials, and many herbal or nutritional interventions lack large-scale reproductive outcome data. Unexplained infertility remains a significant clinical challenge. Inflated outcome claims from any practitioner or product should be approached with caution.
