#20 Pt1: What Wrecks Your Flora Down Under - Antibiotics, the Pill and Yes, Your Toys

Send us Fan MailIn 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 TopicsWhat the gynecological microbiome is and which anatomical areas it coversWhy Lactobacillus dominance — not diversity — is the marker of a healthy gynecological microbiomeThe discovery that the uterus is not sterile: what next-generation sequencing (NGS) revealedThe bidirectional microbiome-hormone axis: how bacteria and oestrogen regulate each otherWhat causes gynecological dysbiosis: the contraceptive pill, sexual intercourse, sex toys, antibiotics, thyroid medications, vaginal hygiene productsNormal menstrual inflammation vs chronic pathological inflammation — and the difference between themHow a dysbiotic microbiome attacks sperm and prevents embryo implantationWhy 50% of bacterial vaginosis cases have no symptoms — and what that means for unexplained infertilityTimestamps00:00 — Intro and episode overview01:00 — What the gynecological microbiome is; the body's multiple microbiomes03:00 — Reproductive ageing: what it means beyond fertility06:00 — Ronny's background and why he entered this field10:00 — Causes of gynecological dysbiosis: the pill, antibiotics, sexual activity, hygiene products15:00 — How the mucosal lining absorbs compounds and why topical exposure matters19:00 — The uterus is not sterile: the NGS sequencing revolution22:00 — Inflammation: normal vs pathological, and the menstrual cycle27:00 — Sperm attack and implantation failure: the fertility mechanismReferences and ResourcesGet Happy website: www.get-happy.comRonny Szelinsky — LinkedIn: https://www.linkedin.com/in/ronny-szelinskyNGS (Next-Generation Sequencing): technique referenced for identifying vaginal and uterine bacterial strainsBacterial vaginosis and Gardnerella vaginalis: standard medical references available on NHS/MedlinePlusInsta/TikTok: @BiohackingEveWebsite: www.BiohackingEve.com
