| Study type | Not Specified |
| Scientific title | |
| Study objectives | To assess the efficacy of 500 mg Testosterone Undecanoate (TU) in combination with either 150 or 250 mg Depomedroxyprogesterone Acetate (DMPA) in suppression of sperm production, while maintaining adequate testosterone levels in fertile Asian men. Due to funding limitations and focus on an alternative intervention, the study was never initiated and has been withdrawn from the World Health Organization (WHO) directory. |
| Ethics approval(s) | Not provided at time of registration |
| Health condition(s) or problem(s) studied | Male contraception |
| Intervention | 1. 500 mg TU and 150 mg DMPA injected at eight week intervals (n = up to 32) 2. 500 mg TU and 250 mg DMPA injected at eight week intervals (n = up to 32) |
| Intervention type | Drug |
| Pharmaceutical study type(s) | |
| Phase | Phase II |
| Drug / device / biological / vaccine name(s) | Testosterone undecanoate (TU), depomedroxyprogesterone acetate (DMPA) |
| Primary outcome measure | 1. Changes in sperm concentrations to azoospermia or severe oligozoospermia at 24 weeks 2. Time to suppress spermatogenesis at 24 weeks |
| Secondary outcome measures | Suppression of gonadotropins and maintenance of normal blood testosterone levels at 24 weeks. |
| Overall study start date | 01/06/2003 |
| Completion date | 01/06/2004 |
| Reason abandoned (if study stopped) | Due to funding limitations and focus on an alternative intervention, the study was never initiated and has been withdrawn from the World Health Organization (WHO) directory. |
