NIH To Launch Male Contraceptive Study.

reports the National Institutes of Health will start recruiting couples for a clinical trial of a male contraceptive gel that is applied to men’s shoulders. The gel contains the hormone progestin, which limits the testes from generating testosterone at a level that supports sperm production. A male contraceptive clinical trial several years ago ended early after some participants experienced depression and mood disorders. The NIH trial is expected to take three years, and if successful, researchers would begin another trial. However, even if the trial produces results, researchers say no pharmaceutical company is willing to manufacture the gel. https://www.wsj.com/articles/the-search-for-a-new-form-of-birth-control-1508173537
