Cycle & Fertility Check

A comprehensive 36-biomarker fertility panel covering reproductive hormones (LH, FSH, oestradiol, AMH, progesterone, prolactin, testosterone, SHBG), full thyroid function, vitamin D, iron studies, B12, folate, and inflammatory markers. Provides the complete hormonal and nutritional picture needed for evidence-based preconception planning or investigating cycle irregularities, covering every modifiable factor that influences female fertility outcomes.

Fertility is not determined by reproductive hormones alone — thyroid function, iron status, vitamin levels, and inflammation all independently affect conception and pregnancy outcomes. This panel covers every blood marker that evidence links to female fertility. AMH (Anti-Müllerian Hormone) estimates ovarian reserve — the number of remaining eggs — and is the most useful single fertility marker. FSH and LH reveal pituitary signalling and cycle phase. Oestradiol and progesterone confirm ovulation and luteal phase adequacy. Prolactin elevation suppresses ovulation and is a treatable cause of infertility. Testosterone and SHBG help identify PCOS — the most common cause of anovulatory infertility. Thyroid dysfunction (both hyper and hypothyroidism) impairs ovulation, increases miscarriage risk, and affects foetal neurodevelopment. Iron deficiency reduces uterine blood flow and is associated with anovulation. Folate is essential for preventing neural tube defects and should be optimised before conception, not after. B12 deficiency affects egg quality and implantation. Vitamin D receptors exist in the uterus and ovaries, and deficiency is associated with reduced IVF success rates. Inflammatory and immune markers screen for conditions like endometriosis and autoimmune factors that impair implantation. This panel replaces the typical fertility workup of 5-6 separate GP orders with a single comprehensive screen.
