Lisinopril

Lisinopril is a blood pressure pill that blocks an enzyme the body uses to narrow blood vessels. It also protects the kidneys in diabetes.

Lisinopril reaches fertility care through one small randomized crossover trial. The trial enrolled 33 men with normal blood pressure and a low sperm count of unknown cause. Sperm counts rose while the men took lisinopril and fell after they switched to placebo. Of the 28 men who finished, 15 improved overall.1

One pilot trial is a thin base, and lisinopril sits outside usual male factor care. It is an open question worth larger study.
