Flutterby™! : Birth Control for Men

New study doesn't show men are wimps about contraception side-effects, but the low vasectomy rate might.

320 men enrolled and 266 completed enough of the study to produce data on how well the product worked. The good news is that the drug combination was very successful and almost 96% of men has suppressed sperm. There were 4 pregnancies for a pregnancy rate of 1.57/100 users. The Pearl Index was calculated as 2.18 pregnancies per 100 person years (basically 100 people use the method and 2.18 get pregnant over that year). The Pearl Index is 1.5-2 for the birth control pill. Other good news is that more than 75% of men said they were satisfied with the method and would use it again.

The study was halted because of an independent review board, not because of the participants.
