A five-marker panel for women considering elective egg freezing — measuring AMH, FSH, LH, oestradiol, and testosterone to assess ovarian reserve.
Elective egg freezing (social egg freezing) has become an increasingly popular option for women who want to preserve their fertility while their reproductive window is still optimal. Success rates are strongly influenced by the age at freezing and the number of eggs retrieved — which in turn depends on ovarian reserve.
The Egg Freezing Readiness Panel provides the five markers most relevant to planning egg freezing:
AMH — the most informative predictor of egg yield per stimulation cycle. Higher AMH means more eggs are likely to be retrieved in each cycle.
FSH and LH — basal pituitary markers assessed on days 2 to 5 that confirm ovarian response potential and screen for PCOS (elevated LH-to-FSH ratio).
Oestradiol — basal oestradiol contextualises FSH on the day of collection.
Testosterone — included because PCOS (associated with elevated testosterone) requires a modified stimulation protocol due to OHSS risk from over-response.
This panel provides the hormonal data fertility clinics use to advise on: the optimal time to freeze, expected egg yield, number of cycles likely needed, and whether any hormonal issues require addressing before stimulation. Venous draw on cycle days 2 to 5. GMC-physician reviewed within 3 to 5 working days.
Understand what each marker measures, why it matters, and what the science says — not just a list of numbers.
Strongest predictor of egg yield per cycle; guides urgency and timing advice for egg freezing.
Basal FSH assesses ovarian reserve status; elevated FSH suggests declining response potential.
Elevated LH-to-FSH ratio is a key PCOS indicator — important for protocol planning due to OHSS risk.
Basal oestradiol confirms the follicular phase hormonal environment and contextualises FSH.
Screens for androgen excess (PCOS); elevated testosterone informs the risk of ovarian hyperstimulation during stimulation.
This panel is designed for adults who want a comprehensive, evidence-based picture of their metabolic health — not a GP referral panel.
Women aged 28 to 38 considering elective egg freezing
Those who want to understand how many eggs they can realistically expect to freeze
Women with suspected PCOS who want hormonal assessment before a freezing consultation
Those who have attended a fertility clinic consultation and want private confirmatory testing
AMH predicts egg quantity, not quality. Egg quality is the primary determinant of fertilisation and embryo development success and cannot be measured by a blood test. A good AMH at 35 does not guarantee that all retrieved eggs will be chromosomally normal or capable of producing a viable embryo. Antral follicle count (AFC) on transvaginal ultrasound is the complementary imaging-based assessment that, together with AMH, gives the most accurate prediction of follicle yield. This panel provides the blood-based component; fertility clinics always perform AFC as part of their pre-treatment assessment. PCOS features identified here should be discussed with the stimulation protocol team at your fertility clinic.

An AMH above 15 pmol/L in a woman under 35 typically predicts a good response (8 to 15 or more eggs per retrieval) — meaning one to two cycles may be sufficient to build a meaningful frozen egg bank. An AMH between 5 and 15 pmol/L suggests a moderate response; more cycles may be needed. Below 5 pmol/L, response will likely be lower (fewer eggs per cycle), though conception from a small number of frozen eggs is still possible, particularly at younger ages. Your physician report will interpret your AMH in the context of your age and expected yield.
The age at which eggs are frozen is the single most important determinant of success. Eggs frozen before 35 have significantly higher fertilisation rates and lower rates of chromosomal abnormality than eggs frozen after 38. Most fertility specialists consider 32 to 36 the optimal window for elective egg freezing — old enough to have clarity on the decision, young enough that egg quality remains high. After 38, both quantity (AMH) and quality decline more steeply, and more retrieval cycles may be needed to bank a meaningful number of eggs. However, successful pregnancies from frozen eggs have been achieved by women in their early 40s.
Most fertility specialists suggest banking 10 to 20 mature eggs to give a reasonable chance of achieving at least one live birth. The probability of live birth from a single thawed egg is approximately 5 to 7% at age 35 to 37 and 3 to 5% at 38 to 40. So freezing 10 mature eggs at 36 gives roughly a 40 to 50% cumulative chance of one live birth. The number of cycles needed to achieve 10 to 20 mature eggs depends on your ovarian reserve (AMH) and age. Understanding your AMH before your clinic consultation allows you to go in with realistic expectations and a clearer financial planning picture.
Women with PCOS typically have high AMH and many recruitable follicles, which means they often produce large numbers of eggs per stimulation cycle. This makes them very good candidates for egg freezing from a response perspective. However, high AMH in PCOS also means elevated OHSS risk. Clinics managing PCOS patients typically use lower stimulation doses, a gonadotrophin-releasing hormone (GnRH) agonist trigger (rather than the standard human chorionic gonadotrophin (hCG) trigger), and a freeze-all strategy for all retrieved eggs. The testosterone and LH-to-FSH ratio in this panel help identify PCOS features before your clinic consultation, allowing the stimulation team to plan appropriately.
This is an important decision that depends on your personal circumstances. Egg freezing (oocyte cryopreservation) preserves unfertilised eggs without requiring a partner or sperm donor decision at the time of freezing — suitable for women without a current partner who want full control over future decisions. Embryo freezing (with a partner’s sperm or donor sperm) is currently more established and may have marginally higher success rates, but requires a sperm source and creates legal implications around the embryos as a couple. Your physician report will provide context for this discussion, and the decision should ultimately be made in consultation with your fertility clinic.
