Plasma testosterone response to short-term human chorionic gonadotropin administration in men with follicle-stimulating hormone suppressed by exogenous estrogen.

Cross-Sectional Study

Human

The study gave men a hormone to temporarily lower FSH, then gave them HCG to see if their testosterone still went up — and it did, just like before. So lowering FSH didn’t stop HCG from boosting testosterone.
