Hormone Health Hub: Expert Insights on Testing, Balance & Better Living — hypothalamic pituitary adrenal

The contraceptive pill is one of the most widely used medications in the world — but its effects on mood, brain chemistry and hormone balance are still poorly understood. This article explores how synthetic hormones disrupt oestrogen, progesterone, cortisol and neurotransmitters, and why some women are far more vulnerable to depression and anxiety as a result.

Discover why topical testosterone replacement therapy is frequently over-prescribed and how outdated serum testing methods may fail to reflect true hormone bioavailability. Learn how saliva and dried blood spot testing provide a more accurate picture of tissue hormone delivery, why physiological testosterone dosing matters, and how excessive testosterone may suppress natural production, reduce receptor sensitivity, and impact long-term hormonal balance, energy, mood, libido, and overall men’s health.

 

Explore the powerful connection between hormones, neurotransmitters, and mood in PMS and PMDD. Learn how progesterone, allopregnanolone, GABA, serotonin, cortisol, and estrogen fluctuations throughout the menstrual cycle may contribute to anxiety, irritability, depression, fatigue, sleep disturbances, and severe premenstrual symptoms. Discover how hormone and neurotransmitter testing can help identify underlying imbalances linked to menstrual mood disorders. 

Low libido in perimenopause is rarely just one thing — it’s a mosaic of hormonal, physical and lifestyle factors. From falling oestrogen and DHEA to thyroid dysfunction and metabolic syndrome, discover what’s really driving the loss of desire and how hormone testing can help.

DHEA and DHEA-S are the most abundant steroid hormones in the body and play a critical role in brain health, mood regulation, and cognitive function. This article explains the biochemical distinction between the two, how they act as neurosteroids, and why measuring DHEA-S is the gold standard for assessing adrenocortical activity.
