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

Single nucleotide variations (SNVs) in the enzymes that metabolise estrogen can significantly alter breast cancer risk — in some cases by as much as 12-fold when multiple variants combine. In this detailed scientific overview, Jillian Harrington PhD of ZRT Laboratory explains how variations in CYP11A1, CYP19A1 (aromatase), CYP1B1, COMT and MnSOD affect the estrogen metabolism pathway, why catechol estrogens are dangerous, and how methylation testing can reveal individual vulnerability.

Testosterone has long been associated with aggression — but new research is revealing a far more nuanced picture. A study published in Nature Communications, involving ZRT Laboratory, found that a single dose of testosterone significantly increased young men’s preference for luxury, status-enhancing goods. Dr. Kate Placzek explores the neuroendocrine science behind this finding — and what it reveals about testosterone’s role in dopamine, reward and social behaviour.

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.

Breast cancer rates have risen from 1 in 30 to 1 in 8 women over the past 30 years — yet the focus remains on treatment rather than prevention. Drawing on 35 years of clinical experience and infrared thermography, this article makes the case that environmental toxins, xenoestrogens, hormone imbalance and lifestyle factors may account for 91–93% of breast cancer risk. Prevention, not just awareness, is the real cure.

An estimated 80% of adults will experience some level of adrenal fatigue in their lifetime — yet it remains one of the most under-diagnosed conditions in modern medicine. When the adrenal glands are chronically overtaxed, cortisol output drops, leaving the body unable to manage stress, stabilise blood sugar or mount immune defences. This article explores the symptoms, causes and what you can do to identify and address adrenal fatigue through targeted hormone testing.
