Why it is timely to bring a new hormonal male contraceptive to the public - A 35-year perspective of the authors.

This perspective provides an overview of issues needed to bring a testosterone-progestogen combined transdermal male hormonal contraceptive to the market. Large-scale phase 2b trials are near completion and a pivotal trial to confirm efficacy and safety has been designed. We believe we are close to accomplishing the steps necessary to bring the first male-directed effective, safe, and reversible pharmaceutical contraceptive approach to the public. If successful, we believe it will provide a new option for couples to consider in their family planning.
