In this episode of The Perfect Stool, host Lindsey Parsons interviews Dr. Diane Mueller, ND, DAOM, a board‑certified sexologist and functional‑medicine practitioner, to explore the interconnectedness of gut health, the genital microbiome, estrogen metabolism, cortisol, and sexual wellness. Dr. Mueller recounts her personal journey from chronic vulvar pain and Lyme/mold illness to a focus on libido, emphasizing how gut dysbiosis, SIBO, infections, and elevated beta‑glucuronidase can disrupt estrogen recycling and lead to estrogen dominance, which manifests as bloating, acne, mood swings, and low libido. She explains the estrogen metabolic pathways (2‑OH, 4‑OH, 16‑OH), the role of phase‑1 and phase‑2 liver detox, and recommends targeted supplements such as DIM, calcium D‑glucarate, indole‑3‑carbinol, NAC, and MCT‑oil with CBD. The conversation also covers the genital microbiome’s reliance on gut‑derived lactobacilli, the impact of nutrient malabsorption, low cholesterol, and vascular health on sexual function, and how orgasm‑driven oxytocin can lower cortisol. Practical advice is given for anal sex hygiene, lube pH, and supplement choices. The episode includes a Podcastathon segment featuring Thomas Myron of Love146, detailing the organization’s origin, programs, and ways listeners can support the fight against child trafficking. Throughout, Dr. Mueller stresses a three‑pillar approach to low libido—physical root causes, personal/psychological factors, and relational communication—while encouraging thorough testing (Dutch test, stool/organic acids, ApoB, CAC score) and self‑advocacy. The episode ends with resources for supplements, testing, and Dr. Mueller’s book "Want to Want It".
