There's also the risk that the drug is not as efficient as expected, and you end up with an unwanted pregnancy, so participating in this trial is never a no-brainer.
- morsch 10y agoPresumably they were strongly advised to use a second method of birth control.
- askmike 10y agoin that case they wouldn't really test whether it works or not..
- tveita 10y agoIt's supposed to lower sperm count, which you could easily verify with a sample.
- sangnoir 10y agoI don't think they were measuring the efficacy on the basis of whether or not the participants conceived - that measure is affected by too many variables. Sperm count is the more reliable metric with reasonable granularity for measuring the effect.
- evandijk70 10y agoI looked up the study, and it seems that participants were not allowed to use a second method of birth control: "Couples enrolled in the efficacy phase were asked to rely only on these injections for contraception." And there were four pregnancies during the study (from the abstract of the study): During the efficacy phase of up to 56 weeks, 4 pregnancies occurred among the partners of the 266 male participants, with the rate of 1.57 per 100 continuing users (95% CI, 0.59 – 4.14)
