SEATTLE, Wash. (Ivanhoe Newswire) – Eighty percent of all women in the US will use it at some point in their lives, but the burden of taking birth control pills could soon be taken away from women.
It’s a daily routine for a lot of women.
Now researchers are working on birth control, for men.
The difficult part is men make a thousand sperm a second! To be an effective contraceptive, sperm count has to go down to zero!
“I think it’s important to have more choices,” Michael Lehmann, told Ivanhoe.
Michael Lehmann has been involved in five testosterone based clinical trials.
He’s taken daily pills, monthly injections, a cream he rubbed on his shoulder, and even had an implant.
“There were very minor side effects, um, I had some slight acne on my scalp,” Lehmann said.
But testosterone could increase the risk of heart disease and prostate cancer. That’s why Dr. John Amory is blocking vitamin A in the testies, which in turn blocks the development of sperm.
“I decided to explore ways of suppressing sperm without using hormones,” John Amory, MD, Professor of Medicine, University of Washington, School of Medicine, told Ivanhoe.
Tests in mice show it works 100-percent of the time.
But still, some doctors are skeptical.
“Hahahaha, a male contraceptive; I don’t think women will trust it,” Sanjay Acerwall, MD, Reproductive Endocrinologist at University of California, San Diego, told Ivanhoe.
While it may take time for men to get used to it, choosing when to have or not have a baby could be in their hands.
Researchers have also found a hormone free way to make the testicles forget how to make sperm. They are testing a drug that targets a protein which is critical for sperm production and it’s reversible. When mice were taken off the treatment, they became fertile again.
