can anyone direct me towards more information dealing with the
contraceptive effects of nifedipine? I have been attempting for some
time to find a male contraceptive, and expirimentation with wet heat
is difficult due to inconvenience as well as difficulty in finding a
clinic in my area that will do sperm tests. however, it has come to
my attention recently that nifedipine, which has been well-tested for
safety, is available without prescription in many forms through
mexico-based pharmaceutical retailers.

so, any more information available on the effects, dosages, and
effectiveness of nifedipine would be appreciated.

thanks
