(KUTV) It’s something women usually take, but researchers are working on a birth control pill for men.

Scientists at Baylor College of Medicine say this pill would have no side effects.

Bill Bandiga has been married 25 years. He and his wife want no surprises.

"I'm close to 50 now. No way in heck I want to have any kids at this point. I want to make sure this is permanent,” Bandiga said.

Doctor Martin Matzuk is working on a change in birth control for men that doesn't require surgery.

"You can see there is lots of movement,” lead researcher Dr. Matzuk said.

What's happening in a Baylor College of Medicine lab is perhaps the most exciting research the department has ever seen.

"We would rank it in the top five, maybe even the top two,” Dr. Matzuk said.

The lab is working on the first birth control pill for men.

Others have tried, but failed because of harmful side effects.

But research published in Cell Medical Journal says JQ1 is different.

"I'll tell you what it didn't do, which is very important. It did not affect the libido of the animals,” Dr. Matzuk explained.

In the past, other pills targeted hormones, but JQ1 targets germ cells and so far in mice, side effects don't exist.

But will that success be the same for men?

Researchers say yes.

"In the mice, it didn't show that effect. But, again, this is only over a one-year period of time and men might be taking this for many years, even decades,” Dr. Matzuk said.

"Interesting idea I think for a younger male,” Bandiga said.

For now, Bandiga is happy sticking with what he knows, even if it means vasectomy.

Doctors are still doing research and clinical trials could start in five years.
