Fertility testing evaluates reproductive hormone levels and ovarian reserve to guide treatment decisions for those trying to conceive, whether naturally or through assisted reproductive technologies like IVF.
Key Insight
AMH tells you about quantity (how many eggs), but not quality. A woman with low AMH can still conceive, while high AMH doesn't guarantee success. FSH, estradiol, and thyroid function together give the full picture.
Core diagnostic markers for fertility / ivf. These are used to diagnose and monitor your condition.
Anti-Müllerian Hormone reflects ovarian reserve - the number of eggs remaining. Critical for IVF planning and predicting response to stimulation.
Follicle-stimulating hormone measured on cycle day 3. High FSH indicates the body is working harder to stimulate ovaries - a sign of diminished reserve.
Luteinizing hormone triggers ovulation. The LH:FSH ratio matters - elevated LH relative to FSH suggests PCOS.
Fertility / IVF affects multiple body systems. Monitor these to catch complications early.
These hormones confirm ovulation is occurring and support early pregnancy
Measured mid-luteal phase (day 21). Confirms ovulation occurred and corpus luteum is functioning.
Above 3 ng/mL confirms ovulation. Above 10 ng/mL is ideal for conception.
Elevated prolactin suppresses ovulation. Common cause of irregular cycles and infertility.
Below 25 ng/mL. Above this may require treatment.
Thyroid dysfunction is a common, treatable cause of infertility and miscarriage. TSH should be optimized before conception.
Even subclinical hypothyroidism affects fertility. Tighter targets for conception than general population.
Below 2.5 mIU/L for conception (stricter than normal 0.4-4.0 range)
Active thyroid hormone. Should be mid-normal range.
0.8-1.8 ng/dL
Elevated androgens suggest PCOS, a leading cause of ovulatory infertility
Male factor contributes to ~40% of infertility cases. Hormone testing complements semen analysis.
Nutritional status affects egg and sperm quality
Deficiency linked to lower IVF success rates. Receptors present in ovaries and uterus.
Above 30 ng/mL (some clinics target 40-60)
Deficiency can cause ovulatory dysfunction and implantation failure.
Above 300 pg/mL
Iron stores affect egg quality. Low ferritin common in women with heavy periods.
Above 30 ng/mL, ideally 50-100
Fertility is not just about one hormone - it's a complex interplay of ovarian reserve (AMH, FSH), ovulation (LH, progesterone), thyroid function, androgen balance, and nutritional status. Both partners matter: male factor accounts for 40% of infertility. A comprehensive workup looks at the whole picture, not just one test.
