Two immunosuppressive drugs may pave the way for male birth control ‘pill’ if what we hear now is anything to go by. Immunosuppressive drugs are given to organ transplant recipients to prevent the body from rejecting the transplanted organ. The two drugs work by inhibiting a ‘chemical’ (enzyme) in the body called CALCINUERIN.
Researchers at the Osaka University in Japan have found a similar chemical in the sperm of mice and following a series of experiments were able to show that if this chemical is altered in the male mice, they would be unable to impregnate the female; the sperms of the mice could not fertilise the eggs of the female.
The researchers then gave the two immunosuppressive drugs to normal mice, they became infertile in 4-14 days of usage, fertility returned when usage was stopped.
