More than 60 years after a birth control pill was developed for women, there is still no

similar federally approved drug for men.

But promising results using a new gel for men might finally change that. William Bringham has the details. The

new gel for men might finally change that.

William Bringham has the details.

Um, no, while this drug is still being tested,

it has already generated a lot of interest.

It's a clear gel that you rub on your shoulder once a day, and early results show that it blocks

sperm production after two to three months of daily use.

Dr. Brian Wynne is an associate professor of clinical obstetrics and

gynecology at the USC Keck School of Medicine and he was involved in this

current study. Dr Wynne thank you so much for being here. So how does this gel work? this and more interest in male contraception. In terms of the way that this works, it is a hormonal method. And so to understand the hormonal system here requires you to understand that it works kind of like a thermostat. It's always measuring how hot or cold your room or your

house is and in this case your thermostat is measuring how much testosterone is in

your body and so if you give testosterone thermosol sense there's too much in the

same way that if it's too hot it'll sense that it's too much and therefore it'll

turn off the heater so in this case you are turning off the testes. You're

turning off the production of testosterone in the body, which will also turn off

the production of sperm. What's nice about that is that we know that this factory is intact.

All you're doing is you're flipping some switches

so that when you flip the switch back on,

then you're gonna have reversal of the sperm production, and you'll have full

production once again.
