For the study,  a 1000 healthy and fertile men between 20 and 45 were given monthly injections of  500mg of testosterone undecanoate in tea seed oil for 30 months. This testosterone-based product caused the disruption of sperm production and hence prevented reproduction.

Better yet, no serious adverse side effects occurred and once the monthly injects were stopped, the sperm count returns to healthy levels by six months.

Of course, further testing will be needed to ensure the injection’s safety, but it’s looking good. Maybe soon, women will be able to say goodbye to the pill.

Quite a lot according to a team of Australian scientists who are trying to develop a ‘remote-controlled controceptive implant for men.’ Right now it’s stll being tested in the laboratory but if successful could provide an alternative to the non-reversable vasectomy.

Made from a specially coated silicone-based material, the implant (a small radio-controlled valve) is no larger than a grain of rice and would be inserted into the vas deferens (the duct which carries sperm from each testicle to the penis) using a hypodermic needle.

Once inserted, the implant valve would open and close as directed by a transmitter that is programmed with the implants unique ID tag.  But the remote control transmitter is not something that would be needed very often as the idea is for the valve to remain closed as a form of contraceptive, only to be opened if conception is being considered.

So to avoid any unwanted surprises, you’d want to make sure you didn’t get the ’sperm remote’ confused with the TV remote.
