Your fertility timeline is yours to understand.
Whether you're planning now or planning later — knowledge is power.
This panel measures ovarian reserve, hormone balance, thyroid function, and iron status — the key factors that determine fertility readiness, regardless of your timeline.
Why this matters for women
Fertility isn't just about trying to get pregnant right now. It's about understanding your reproductive health at any age. AMH (Anti-Mullerian Hormone) tells you about your ovarian reserve — how many eggs you have left — and it declines with age in a way that's unique to each woman. Some women have diminished reserve in their early 30s; others maintain robust reserve into their 40s. You can't know without testing. Beyond ovarian reserve, fertility depends on a cascade of hormones working together: estradiol and progesterone for cycle regulation, prolactin for menstrual function, and TSH for thyroid health (even mild thyroid dysfunction increases miscarriage risk). Iron and ferritin are critical too — iron deficiency during pregnancy causes complications for both mother and baby, and it's best addressed before conception. For women with PCOS, this panel includes androstenedione and 17-OH progesterone to assess androgen excess and adrenal function.
Symptoms to watch for
What we test
AMH
Anti-Mullerian Hormone — the best single marker of ovarian reserve (how many eggs remain). Unlike other fertility markers, AMH can be tested any day of your cycle and gives a reliable picture of your reproductive timeline.
Estradiol
The primary estrogen that drives follicle development and ovulation. Tested in context with FSH, estradiol helps assess ovarian function and reserve.
Progesterone
Essential for preparing the uterine lining for implantation and maintaining early pregnancy. Low progesterone is one of the most common causes of difficulty conceiving and early miscarriage.
Prolactin
Elevated prolactin can suppress ovulation and cause irregular periods. Testing is important for women with cycle irregularities or difficulty conceiving.
TSH
Thyroid function is critical for fertility. Even subclinical hypothyroidism (TSH 2.5-4.5) increases miscarriage risk and can impair ovulation. The American Thyroid Association recommends TSH below 2.5 for women trying to conceive.
Iron, TIBC & Ferritin Panel
Complete iron status assessment. Iron deficiency is the most common nutritional deficiency in women of childbearing age and must be addressed before and during pregnancy for healthy fetal development.
hCG
Human chorionic gonadotropin — the pregnancy hormone. Used to confirm pregnancy and monitor early pregnancy progression. Doubling time provides important information about pregnancy viability.
Androstenedione
A hormone precursor that's elevated in PCOS and adrenal disorders. High androstenedione causes acne, excess hair growth, and disrupts ovulation.
17-OH Progesterone
An adrenal marker that helps distinguish between ovarian and adrenal causes of androgen excess. Important for women with PCOS-like symptoms to get the right diagnosis.
Who should consider this panel
- Women considering pregnancy in the next 1-5 years
- Anyone with irregular, absent, or very heavy periods
- Women with PCOS or suspected PCOS
- Those who've experienced miscarriage or difficulty conceiving
- Women considering egg freezing who want to assess ovarian reserve
