According to the ACOG technical bulletin on sterilization, 1996,
"Pregnancy rates following vasectomy are less than 1% in most studies
and usually result from failure to occlude the correct structure,
unprotected intercourse too soon after the operation, or spontaneous
recanalization. Unlike tubal occlusion in women, vasectomy is not
immediately effective: about 3 months or 20 ejaculations are needed to
flush the vasa of viable sperm. Postvasectomy semen analysis should be
performed to determine the effectiveness of the procedure." In their
patient booklet on sterilization the statement is "well under 1%." I
think 1% is a high figure and will scare off too many people.
