In Part 1 of this conversation with Ronny Szelinsky, founder of Get Happy, we explore the gynecological microbiome — the bacterial community that spans the vagina, uterus, cervix, and urinary tract. Ronny explains why this microbiome operates by completely different rules to the gut, what happens when it becomes dysbiotic, and how its disruption can silently undermine fertility, hormonal health, and longevity. The science is newer than most people realise: the uterus was considered sterile until approximately 2018.

Key Topics

• What the gynecological microbiome is and which anatomical areas it covers
• Why Lactobacillus dominance — not diversity — is the marker of a healthy gynecological microbiome
• The discovery that the uterus is not sterile: what next-generation sequencing (NGS) revealed
• The bidirectional microbiome-hormone axis: how bacteria and oestrogen regulate each other
• What causes gynecological dysbiosis: the contraceptive pill, sexual intercourse, sex toys, antibiotics, thyroid medications, vaginal hygiene products
• Normal menstrual inflammation vs chronic pathological inflammation — and the difference between them
• How a dysbiotic microbiome attacks sperm and prevents embryo implantation
• Why 50% of bacterial vaginosis cases have no symptoms — and what that means for unexplained infertility
