Hormone Health Hub: Expert Insights on Testing, Balance & Better Living — corpus luteum function

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.

Explore how hormones fluctuate through every stage of the menstrual cycle — from menarche to menopause — and discover how estrogen, progesterone, LH, and FSH influence mood, energy, fertility, PMS, migraines, weight changes, and overall women’s health. Learn how menstrual cycle mapping can help identify hormone imbalances and provide deeper insight into symptoms throughout the month.
