Male infertility and antioxidants: one small step for man, no giant leap for andrology?

Oxidative stress is detrimental to spermatozoa and is acknowledged to be a common pathology in infertile men. Antioxidant supplements, therefore, represent a logical therapeutic approach, although the recent Cochrane review recommends cautious interpretation of publications and findings to date. This commentary considers whether male fertility supplements have a place in current reproductive medicine practice. Importantly, although sperm selection for intracytoplasmic sperm injection is a common research theme, survey data show that men would prefer medication to achieve natural conception, rather than treatment to improve assisted reproductive technology (ART) success. A total of 27.1% (n = 112), 26.6% (n = 110) and 24.5% (n = 101) respondents indicated they (or their male partner) would undertake medical treatment to attempt natural conception for up to 6 months, 12 months and 2 years, respectively. A total of 63% indicated that they would be prepared to participate in a clinical trial and 57% would defer ART by 6 months to do so. This information represents the beginnings of a dialogue with patients and stakeholders and should be used to shape research efforts.
