Pill or injection instead of vasectomy?
An Australian team of scientists took an entirely different approach to solving the conundrum of the male contraceptive pill. They developed a pill which does not contain any hormones but which stops the release of sperm. Similar to a temporary vasectomy
, the new pill blocks two proteins which are involved in the process of ejaculation. It does not stop the production of sperm, it just stops sperm from coming out. However, this mechanism has so far only been tested on mice and it is not known whether it will work in humans.
A similar technique is currently being trialled in India. It involves an injection in the scrotum, which practically works like a reversible vasectomy. The initial injection can be reversed with another injection at later date. Current trials with human volunteers seem promising but it may still be years before the injection can be produced and made available to the public.
