On the market there are supplements aimed at improving male fertility. Inside there are zinc and folate, both essential substances in the development of sperm.

The women completed questionnaires to monitor possible conceptions. The researchers found no significant difference between the first and second groups. In the group that took the supplements, there were 404 successful pregnancies, about 34%. In that of placebo, there were 416, about 35%. The semen samples taken from the two groups also showed a similar number of spermatozoa, having roughly the same shape and motility.
