a contraceptive pill for men,
along gender lines.
언제죠?"
I have in store for their testicles.
하려는지 궁금해합니다.
필요한 걸까요?
annually in the United States,
임신이라면요?
unintended pregnancies
임신으로 인해
of the more than one million abortions
많은 수의 낙태가
has fallen in the last few years
비중은 지난 몇 년 간 감소하여
are using effective, long-acting,
효과적이고 오래 지속되는
사용하기 때문입니다.
becoming a real possibility
of contraception for women:
정말 많습니다.
shots, sponges, rings, etc.
스펀지, 질 내 삽입용 링 등이죠.
for 30 percent of all contraceptive use,
relying on vasectomy
relying on condoms for contraception
콘돔에 의지할까요?
failure rate of over 15 percent?
달하는 데도 말이죠.
can't either safely take
for reasons such as blood clots,
여전히 부족한 실정이며,
would be useful, the next question is:
다음과 같은 질문이 따르겠죠.
swim towards or bind to the egg.
못 가게 하는 겁니다.
to be really difficult,
in the small volume of the ejaculate
약물을 투입하는게 쉽지 않으며
the female reproductive tract.
살아있을 수 있기 때문입니다.
done on the second approach,
더 의존하게 되었는데
sperm production entirely.
완전히 제거하는 것이죠.
that men make a lot of sperm.
무수히 많이 만들어서에요.
수천 개의 정자를 만드는데
of sperm production
끌어내려야 합니다.
hormones to suppress sperm production.
정자의 생산성을 낮추는 것입니다.
when administered together,
이 2가지가 함께 제어된다면
to the testes to make sperm,
생성하는 것을 억제하게 됩니다.
three to four months will stop.
don't respond to these hormonal regimens
호르몬 요법이 통하지 않는데
my colleagues and I
to male contraceptive development,
방법을 시도해왔습니다.
the administration of hormones.
방식도 진행해봤는데
the function of vitamin A in the testes.
억제하는 실험도 진행했습니다.
it's been known
지난 90년을 넘는 기간 동안
알려졌기 때문이죠.
of vitamin A in their diet
섭취하는 동물들은
when the vitamin A is reintroduced.
정자를 다시 만들기 시작합니다.
to something called retinoic acid.
레티노산으로 변환됩니다.
is found only in the testes.
고환에서만 존재하고요.
that we are attempting to block.
효소인 것이죠.
should deprive the testes of retinoic acid
고환의 레티노산을 제거할 수 있고
elsewhere in the body.
비타민 A의 기능은 그대로 유지됩니다.
of such a male contraceptive
뛰어넘을 것입니다.
about the effect that it would have
짐작해보는 것이죠.
his contraceptive status over time.
지속적으로 파악할 수 있다는 거죠.
home sperm-testing devices
정액 측정기를 전달했는데
and share the result with his partner.
결과를 파트너와 공유할 수도 있죠.
would feel very comfortable
coupled with a male contraceptive,
이러한 피임 장치를 통해
in preventing unintended pregnancy.
남성의 역할이 확대될 수 있습니다.
on male contraception
피임 방식을 개발함으로써
a better future for couples,
노력하고 있으며
considered just "a woman's issue,"
간주되지 않고
for couples to decide together.
자리잡도록 만들죠.
필요한 걸까요?
rates of unintended pregnancy and abortion
낮추는데 기여하고
