There are a lot of misconceptions about medications that can improve male infertility.  Unfortunately, most data shows that most medications used to improve male fertility do not significantly improve sperm parameters, pregnancy, or live birth rates, except for fairly rare specific situations.  Similarly, vitamins and supplements have not been proven to improve male fertility or pregnancy/live birth outcomes.  Dr. Parviz Kavoussi lectures to the urology department at the resident conference regarding the effective medical treatments for male infertility as well the treatments that have not been proven to be effective, and some that may even be harmful.  Patients should consult with specialized reproductive urologists prior to considering vitamins, supplements, or medications for male infertility.
