To answer you question, I do not know what they were compensated. But I suppose if you already had the amount of children you wanted and were considering the ole snip snip, this might have been a considerable option. Maybe it's what they wanted? I do agree though that if this were a young man, I sincerely hope they made some frozen samples before committing to this study.

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.

Presumably they were strongly advised to use a second method of birth control.

[evandijk70]

I 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)

Thanks for the correction.

[askmike]

in that case they wouldn't really test whether it works or not..

[sangnoir]

I 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.

[tveita]

It's supposed to lower sperm count, which you could easily verify with a sample.

Q: Anyone know how much the participants were compensated for taking part in the study?

A: To answer you question, I do not know what they were compensated.

Yes they did.

[lightbyte]

"I do not know" is not normally acceptable as an answer. The OP still does not know whether the participants were compensated.
