Hormones, HRT and Contraceptive Methods: Dr. Tim Hlavinka on UTIs, Part 1


February 18, 2026

Dr. Tim Hlavinka, a board-certified urologist specializing in recurrent UTIs and women’s health, explains how hormonal shifts drive infection risk throughout a woman’s life. From puberty and pregnancy to perimenopause and menopause, he outlines how estrogen fluctuations affect the vaginal microbiome, tissue integrity, and susceptibility to infection. The discussion also explores contraceptives, hormone replacement therapy, and why individualized hormone care is often key to prevention.

Key Take Aways

Hormonal Milestones Increase Risk


UTI risk spikes during puberty, pregnancy, and menopause transitions.

Estrogen Protects Vaginal Tissue


Low estrogen weakens tissue integrity and increases infection susceptibility.

Oral Contraceptives May Suppress Estrogen


Some women experience profound estrogen reduction on the pill.

Menstrual Cycle Affects Microbiome


Hormone fluctuations shift vaginal chemistry and infection vulnerability.

Individualized HRT Is Essential


Hormone therapy must be tailored to each woman’s needs.

Topical Estrogen Is Often Safer


Vaginal and transdermal delivery avoids liver-related hormone complications.
