Testosterone and androstenedione are positively associated with anti-Müllerian hormone in premenopausal women
Abstract
OBJECTIVE: To document associations between anti-Müllerian hormone (AMH) and circulating androgens in nonhealthcare-seeking premenopausal women.
DESIGN: Community-based, cross-sectional study.
SETTING: Eastern states of Australia.
PARTICIPANTS: Women aged 18-39 years not using systemic hormones, not pregnant or breastfeeding within 3 months, and not postmenopausal.
MEASUREMENTS: AMH, measured by the Beckman Access 2, 2 site immunometric assay from fresh samples, and testosterone, androstenedione, dehydroepiandrosterone (DHEA) and 11-oxygenated C19 steroids, measured by liquid chromatography-tandem mass spectrometry.
RESULTS: Data were available for 794 women, median age of 33 years (range: 18-39). 76.1% were of European ancestry and 48.2% were parous. Serum AMH was positively associated with testosterone (rho = .29, p < .001) androstenedione (rho = .39, p < .001) and DHEA (rho = .10, p = .005) but not 11-ketoandrostenedione or 11-ketotestosterone. When adjusted for age, body mass index and smoking, using quantile regression, independent positive associations remained between AMH and testosterone (β coefficient: 20.90, 95% confidence interval [CI]: 13.79-28.03; p < .001) and androstenedione (β coefficient: 5.90, 95% CI: 3.76-8.03; p < .001). The serum concentration of testosterone was greater at the top AMH quintile than other quintiles (0.56 nmol/L [range: 0.21-1.90] vs. 0.36 nmol/L [range: 0.13-0.87]; p = .001) in women with self-reported polycystic ovary syndrome.…
How strong is the evidence?
Evidence Hub reads this as a cross-sectional, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause. Reported size: 794 participants or records.
