This June the largest effort in the U.S. to test a new hormonal male contraceptive starts—with support from NIH.
Contraceptives help prevent pregnancy. Currently condoms and a vasectomy are the most effective male contraceptives.
The new clinical trial is testing a contraceptive gel that men rub on their arms and shoulders daily to reduce sperm count.
The trial is led by the Eunice Kennedy Shriver National Institute of Child Health and Human Development. It runs until 2022.
