A prospective study was designed to investigate the effects of recombinant human follicle-stimulating hormone (rhFSH) on seminal anti-Müllerian hormone (AMH) levels in men with idiopathic oligoasthenoteratozoospermia (iOAT), researching possible relationships between the seminal AMH behavior and the response to the treatment. Thirty-nine men who were candidates for intracytoplasmic sperm injection (ICSI) because of iOAT were enrolled. Patients were treated on alternately days with 150 IU of rhFSH for at least 3 months before assisted reproduction cycles. Main outcome measures were seminal AMH concentrations before and after rhFSH therapy. After treatment, 16 subjects (responders) showed an improvement in their sperm count compared to baseline (7.6 ± 2.9 vs. 19.3 ± 7.7, p < 0.01) whereas 23 men (non-responders) experienced no sperm modifications. Baseline seminal AMH concentrations were significantly higher in responders than in non-responders (53.0 ± 30.6 vs. 34.6 ± 18.5, p < 0.025). Following therapy, a greater increase in AMH levels was observed in responders compared to non-responders (Δ = 24.8 ± 36.4 vs. Δ = 6.4 ± 11.2, p < 0.028). Seminal AMH levels significantly and positively correlated with sperm count (after rhFSH treatment rho = 0.647, p < 0.001). Our study suggests that rhFSH improves sperm count in a quota of iOAT men, and the subjects who respond to the treatment have higher baseline seminal AMH concentrations than the patients who are not responsive. Seminal AMH could be helpful to select those infertile men who may benefit from rhFSH treatment.
