Medical history, physical and andrological examinations, hormonal and seminal parameters, therapeutic management and pregnancy data were collected.

Following FSH administration (mean therapy duration 9.1\u00a0\u00b1\u00a07.1 months), 43 pregnancies were recorded (27.6%), of which 22 occurred naturally and 21 after assisted reproduction. A significant increase in sperm concentration (9.9\u00a0\u00b1\u00a012.2 vs. 18.9\u00a0\u00b1\u00a038.9 million\/mL, <jats:italic>p<\/jats:italic>\u00a0=\u00a00.045) was detected after treatment, together with a significant increase in normozoospermia (from 1.0% to 5.1%, <jats:italic>p<\/jats:italic>\u00a0=\u00a0.044) and a reduction in azoospermia rate (from 9.8% to 7%, <jats:italic>p<\/jats:italic>\u00a0=\u00a00.044). Dividing the cohort in FSH\u2010responders and non\u2010responders, in terms of pregnancy achieved, higher sperm concentrations (15.7\u00a0\u00b1\u00a026.6 vs. 22.2\u00a0\u00b1\u00a025.7 million\/mL, <jats:italic>p<\/jats:italic>\u00a0=\u00a00.033) and progressive sperm motility (18.0\u00a0\u00b1\u00a018.2 vs. 27.3\u00a0\u00b1\u00a011.3, <jats:italic>p<\/jats:italic>\u00a0=\u00a00.044) were found in pregnancy group.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Our experience suggests that FSH, empirically administered to men with idiopathic infertility, leads to pregnancy in one out of four patients and increases sperm concentration.
