Male Contraception Study (DMAU IM CCN015)

Male Contraception Study (DMAU IM CCN015)

The purpose of this study is to test how safe DMAU is and how well it is tolerated when given to men as an injection. This study will also look at how the medication is metabolized in the body (how fast it is absorbed into the bloodstream and how quickly it is cleared out of the body) and how it affects the hormones controlling the function of the testes.

DMAU has been given to a very small number of men before. The long-term goal of studying this medication is to use it as a male contraceptive (birth control).

The study will take approximately 5-7 months to complete. During this time you will have to come to the clinic for approximately 12-16 visits; the exact number of visits will depend on how quickly your sperm count returns to normal after receiving the injection.

Participant Eligibility

Men who join the study should be healthy and between the ages of 18-50 years and will be required to use an effective method of contraception if they have a female partner (i.e. at a minimum, condom for the male subject and an effective contraceptive for the female partner).

  • Able to provide semen samples
  • No participation in a research study within 30 days of screening visit
