The Midlife Hormone Guide: HRT, Libido, Brain Fog & How to Feel Like You Again

The Midlife Hormone Guide: HRT, Libido, Brain Fog & How to Feel Like You Again

Feeling foggy, flat, or just not yourself? You’re not alone — and your hormones could be the reason. In this insightful episode, Dr Sunita Chelva, Dr Aoife O’Sullivan, and Dr Rachel Rubin explain how hormonal changes in perimenopause affect your brain, mood, sleep, libido, and energy — and how HRT, testosterone, and vaginal hormones can help restore balance and wellbeing.


In this episode, you’ll learn:

  • Why there’s no “too young” age to explore HRT when symptoms impact life.
  • How the pill differs from HRT and when body-identical hormones matter.
  • What testosterone can (and can’t) do for libido, focus, and fatigue.
  • The role of estrogen and progesterone in brain, bones, sleep, and heart.
  • How to balance benefits and risks when deciding how long to stay on HRT.
  • Why vaginal hormones (estrogen, DHEA, testosterone) support comfort, continence, and sex at any age.
  • Practical guidance for monitoring and dosing without over-testing.
  • A fresh look at what “natural menopause” means today.
