Abstract
Methods for achieving human male contraception are described in which compounds that substantially inhibit the movement of mannose lectins on the surface of human male sperm cells are administered to human male patients, and the inhibition achieved provides a reversible infertility that can serve as a means of birth control. The use of calcium (Ca.sup.+2) ion channel blocking pharmaceutical compositions is described, particularly the drugs nifedipine, verapamil, and calcium ionophore A23187.
