ENDO: Novel Male Contraceptive Gel May Achieve Faster Sperm Suppression

A novel male contraceptive gel suppresses sperm production faster than other hormone-based methods for male birth control, according to a phase 2 study presented at the annual meeting of the Endocrine Society, held from June 1 to 4 in Boston.

Danielle Gross, from the Eunice Kennedy Shriver National Institute of Child Health and Human Development at the National Institutes of Health in Bethesda, Maryland, and colleagues assessed the time to sperm suppression (concentration ≤1 million/mL) with daily self-administration of segesterone acetate (8 mg)/testosterone (74 mg) combination gel in 222 healthy men.
