Abstract

Background: Gonadotropins administration have been demonstrated effective for the treatment of idiopathic male infertility, even if no clear data regarding their specific mechanism of action on semen quality are at the moment available. Aim: To evaluate the effect of highly purified FSH (hpFSH) administration on standard semen parameters, sperm oxidative stress, and sperm chromatin structure and DNA fragmentation. Material and methods: In the current prospective baseline-controlled study, 36 subjects with male idiophatic infertility were enrolled. Baseline clinical and biochemical data were evaluated. Before and after 3 months of treatment with hpFSH, sperm samples were collected and standard semen analysis, reactive oxygen species (ROS) assessment and sperm DNA fragmentation were evaluated. Results: A significant (p<0.05) improvement from baseline in standard seminal parameters was observed. A significant (p<0.05) reduction in sperm ROS levels and DNA fragmentation was observed. Statistically significant (p<0.05) correlations between variation in ROS levels and both seminal parameters and DNA fragmentation variations were detected. Conclusions: Three months of hpFSH administration seems to reduce ROS and DNA damage in subjects with male idiopathic subfertility improving semen parameters. Further evidences from well-designed randomized double-blind placebo-controlled studies are needed in order to confirm our preliminary results.
