Hormone Health Hub: Expert Insights on Testing, Balance & Better Living — Fertility Profile

If you are experiencing infertility issues, understanding which hormones to test — and why — is the essential first step. Dr. Alison McAllister of ZRT Laboratory explains the full fertility hormone profile: from LH and FSH as indicators of ovarian reserve, to estradiol, progesterone and testosterone for ovulation health, adrenal hormones cortisol and DHEA-S, thyroid markers including TPO antibodies, and the often-overlooked role of vitamin D in fertility and PCOS.

Infertility affects 8–12% of couples worldwide, yet many of the hormonal causes — from undiagnosed Hashimoto’s and PCOS to luteal phase defects and thyroid dysfunction — go undetected by standard testing. A comprehensive first-line fertility hormone panel covering sex hormones, thyroid, adrenal markers and ovarian reserve can identify what is really getting in the way of conception, and dramatically improve the odds of success with fertility treatments.
