A comprehensive hormone and blood health profile assessing the key drivers of menstrual regularity and ovulation — including FSH, LH, Estradiol (E2), Progesterone, Prolactin, TSH and FBC — to investigate irregular cycles, ovulatory issues and fertility concerns.
A healthy menstrual cycle relies on the precise balance of hormones that trigger follicle development and ovulation. If this balance is disrupted, it can lead to irregular, absent, or heavy periods, difficulties conceiving, and symptoms such as fatigue, mood swings, and hormonal imbalance.
The Menstrual Cycle & Ovulation Control Profile from Vitalync Diagnosis measures the core reproductive, thyroid, and blood health markers that influence cycle timing and ovulation. This provides a clear, comprehensive picture to help guide your next steps in fertility planning or cycle regulation.
Women with irregular, absent, or heavy periods
Those facing difficulties conceiving or tracking ovulation
Individuals with suspected PCOS, early menopause, or luteal phase issues
Women experiencing fatigue, mood changes, or other signs of hormonal imbalance
Those undergoing fertility treatment or cycle regulation
FSH (Follicle-Stimulating Hormone) — Reflects ovarian follicle stimulation; elevated levels may suggest reduced ovarian reserve or menopause transition.
LH (Luteinising Hormone) — Triggers ovulation; imbalances are often seen in PCOS and anovulatory cycles.
Estradiol (E2) — The primary oestrogen regulating follicle development and uterine lining growth.
Progesterone (PRG) — Confirms ovulation and luteal adequacy; low levels may indicate anovulation or luteal defects.
Prolactin (PRL) — Elevated levels can disrupt ovulation and affect menstrual cycle regularity.
TSH (Thyroid-Stimulating Hormone) — Thyroid dysfunction can contribute to irregular cycles and fertility issues.
Full Blood Count (FBC) — Evaluates red and white cells, plus platelets, to identify anaemia or infection that may worsen menstrual symptoms.
FSH, LH, Estradiol (E2): usually measured on cycle days 2–5
Progesterone: around 7 days before your expected period (e.g., day 21 of a 28-day cycle) to confirm ovulation
Your clinician may recommend adjustments depending on your cycle length, contraception, or treatment plan
By reviewing reproductive hormones, thyroid function, and blood health together, this profile helps:
Pinpoint the causes of irregular cycles or ovulation problems
Differentiate between PCOS, menopause transition, or thyroid-related issues
Confirm whether ovulation is occurring and if luteal function is adequate
Provide a clearer foundation for lifestyle changes, fertility treatment, or further clinical investigations
