“…Some Authors (Acosta et al ., ; Matorras et al ., ; Kamischke et al ., ; Ben‐Rafael et al ., ) and also some systematic reviews (Kamischke & Nieschlag, ; Kumar et al ., ) denied evidence in support of FSH treatment for enhancing male infertility. On the other hand, more numerous and recent studies (Acosta et al ., ; Bartoov et al ., ; Ashkenazi et al ., ; Arnaldi et al ., ; Foresta et al ., , ; Caroppo et al ., ; Baccetti et al ., ; Paradisi et al ., ) and newer meta‐analyses (Isidori et al ., ; Attia et al ., ) including larger number of studies confuted the previous outcomes, demonstrating a significant FSH action on sperm parameters and pregnancy rate in idiopathic male‐factor infertility.…”
