Hormone Health Hub: Expert Insights on Testing, Balance & Better Living — fertility hormone testing

Saliva hormone testing is a non-invasive, scientifically validated method for measuring the bioavailable fraction of key hormones — including cortisol, oestrogen, progesterone, testosterone, and DHEA — from the comfort of home. Unlike standard blood tests, which measure total hormone levels including the inactive, protein-bound fraction, saliva testing reflects the hormones that are actually active in tissues and driving biological effects. Combined with LCMS (liquid chromatography tandem mass spectrometry) technology, saliva testing offers exceptional accuracy, sensitivity, and clinical relevance for assessing hormone balance, monitoring hormone therapy, and understanding the root causes of symptoms such as fatigue, mood changes, poor sleep, and hormonal imbalance.

PCOS-related fertility challenges are often driven by hidden insulin resistance, hormone timing issues, and overlooked thyroid or adrenal imbalances. This guide explains the most effective fertility tests and treatment strategies for PCOS—showing how cycle mapping, metabolic testing, and personalized interventions can restore ovulation, improve egg quality, and support long-term hormonal health.

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 1 in 8 couples worldwide — yet many are rushing into expensive IVF without first addressing the hormonal imbalances that may be silently undermining their chances. In this wide-ranging clinical discussion, Dr. Alison McAllister of ZRT Laboratory shares her expertise on the hormonal causes of infertility in both men and women, the key tests that are too often missed, and the complementary strategies that can dramatically improve outcomes.

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.
