Brief Summary
The long term objective is to develop a new male hormone Dimethandrolone Undecanoate (DMAU) as a male hormonal contraceptive. The study has two parts. The first is a dose escalating study in healthy to assess the safety and tolerability of single dose oral administration of DMAUin healthy men.(Completed) The second is to study the safety and tolerability of DMAU after 28 days of repeated daily dosing of DMAU in healthy men. (Currently Recruiting) In both parts the investigators will also study the pharmacokinetics of Dimethandrolone (DMA) in the serum after oral administration of DMAU.
