A team of scientists here, which is conducting research to develop a male contraceptive, has identified and tested on animals a protein that can temporarily suppress male fertility. The research studies and experiments have been carried out with the aim of producing a vaccine which could serve as an option to condoms to prevent unwanted pregnancies.
The existing options in male contraception include condoms, withdrawal method and vasectomy. While condoms and withdrawal are not found acceptable and have high failure rates, vasectomy, though most effective, is a permanent procedure with less chance of reversal.
The need of the hour is to discover a new contraceptive method, which is safe, effective, affordable and simultaneously, rapidly reversible without problems.
The initial research was conducted on rats, followed by rabbits, marmoset (small monkeys) and now bonnets (large monkeys). These will be followed by stringent human trials.
