Let's talk about sex.
-
I know that's the last thing most of you wanted to hear me say, but I have big science-related
-
news about it!
-
Right now clinical trials are underway for a new form of birth-control for men.
-
Currently if you're a man and you want to be the responsible one while doinking, there's
-
really only two options - a vasectomy, which is not convenient or always reversible; or
-
a condom, which is convenient, cheap, and effective at stopping both pregnancies and
-
STDs when used correctly.
-
But some men don't like the way a condom affects the sensation of sex and would rather
-
do without it.
-
Or so I've heard.
-
So the two methods of male birth control rely on physical barriers to stop sperm from reaching
-
an egg.
-
By contrast, there are a lot of female birth control options, and most of them use hormones
-
to prevent an egg from being around in the first place.
-
So what's stopping men from using some kind of hormonal birth control too?
-
Well in theory, nothing really, and male hormonal birth control has been tested before, though
-
so far none have been successful.
-
This new clinical trial is aiming giving it another shot, testing the drug on men in 7
-
countries around the world.
-
The new drug uses two hormones.
-
One is progestin, a synthetic form of the steroid/hormone progesterone that women's
-
bodies use to regulate ovulation and pregnancies.
-
The purpose of the progestin in the experimental new male birth control is to lower sperm count.
-
But to prevent the progestin from negatively impacting the men's sex drive or causing
-
other changes like increased acne or weight gain, the second hormone present is testosterone.
-
That may sound counterproductive since testosterone plays a role in sperm production, but actually
-
when a man's body gets testosterone from an outside source, the testes stop producing
-
it and sperm count drops as well.
-
Perhaps best of all is the form this birth control comes in.
-
It's a gel that's intended to be rubbed on the arms and shoulders, so guys there's
-
no excuse not to use it because it doesn't feel good.
-
Heck you play your cards right and you can literally get a massage out of it.
-
A rub-on gel is a lot kinder of a delivery system than say a pill, or a vaginal ring,
-
or an IUD, or an implant, or a shot, or basically any method women currently have for hormonal
-
birth control.
-
But it's not something that a man can slap on, give himself a quick rub, and get right
-
to the business of no-baby-making.
-
Men make 1,000 sperm a second, they are just churning out DNA bullets all the time.
-
To be sure all those little meiosis tadpoles are culled to safe levels, the trial is having
-
men rely on other contraceptives while they apply the gel daily for almost 20 weeks.
-
After sperm counts drop to sufficient levels, the men will use the gel exclusively for a
-
year.
-
Fingers crossed they don't accidentally have children to whom they'll one day have
-
to explain they were the result of a science experiment gone wrong.
-
Once a year has passed they'll stop using the gel and researchers will track them for
-
six months to make sure there are no long term side effects.
-
The trial should wrap up by 2022, and if all goes well it will be ready… for more testing.
-
More studies involving thousands of men will be necessary before regulators like the U.S.
-
Food and Drug Administration give it the all clear, so it's not hitting shelves anytime
-
soon.
-
Another birth control option for men is a good thing, choice always is unless you're
-
Chidi from The Good Place.
-
But what does this mean for women?
-
All the birth control options I mentioned for them are much more invasive than a rub
-
on gel, and each has their own drawbacks, like side effects from changes in hormone
-
levels, scarring from implants, or pain when an IUD falls out of place.
-
If this trial goes well could they have a gel too?
-
As it happens the same company developing this gel is working on a progestin and estradiol
-
gel for women.
-
So a more convenient birth control could be on the horizon for women too.
-
Or this gel could eliminate the need for female birth control all together.
-
Maybe if the man in the relationship uses this gel for birth control, then his partner
-
can stop taking birth control all together if she so chooses.
-
Whatever happens, just stay safe out there.
-
Would y'all use this?
-
I know I would… if there was a need.
-
I have a condom at home in a glass case that says “break glass in case of miracle.”
