我希望能以某种方式对男性而不是女性绝育，他们会把这作为一种选择吗？

I wish they could somehow make a birth control for men instead of women. Will they ever give this as an option?

There’s a fundamental problem with the male pill compared to female pill. Women naturally go through a cycle of fertility and infertility every month and with every child, men don’t.
在男性避孕药和女性避孕药方面，这是个基本问题。女性生来每个月，和生每个孩子时，都会面临不孕的循环，男性则不会。

Male pill

Female pills work by telling the ovaries the body is pregnant, so they shouldn’t produce an egg this month and they oblige. It’s a completely normal response to pregnancy and the female pills simulate pregnancy for the body.
女性避孕药是欺骗卵巢这句身体已经怀孕了，所以卵巢这个月就不会再生产它们本应生产的卵子。它就像完全正常且自然的妊娠反应，女性避孕药就是这样模仿了怀孕的身体。

Males remain fertile from puberty into old age. It is possible for an 85-year old man to concieve a child, if he manages to get his junk to work.
男性从青春期到老年，一直保持着繁育能力。

Sperm quality drops and the odds of a successful insemination are low, but that’s because he’s old and his organs aren’t performing as well as they did. There’s no natural off switch for male reproductive system as there is with women.
当男性逐渐变老，他的器官也逐渐衰退，精子的质量下降，成功授精的概率也会下降。对于男性的生殖系统，没有一种像女性一样的自然的开关。

That’s why the male pill is an inherently different beast to the female pill, the physiology of the two sexes is different. Impotence is a common side effect and while that’s certainly effective in preventing pregnancy, it makes the pill rather pointless.
这就是男性避孕药生来就与女性避孕药大不相同的原因。两性的生理结构是不同的。阳痿是一种常见的药物副作用，所以在避孕中发挥着重要作用，那让避孕药更无意义了。

Then there are the societal issues. If a woman takes the pill she knows she is protected and only needs to trust herself and the modern medicine. If the male is on the pill she needs to trust him. A pregnancy will affect her far more than it will the male no matter what happens, so most women will perfer the female pill for that reason alone.
有一些社会问题。如果女人吃了避孕药，她知道自己是被保护的，只需要相信自己，相信现代医疗技术。如果男人服下避孕药，那么女人就得相信男人。无论什么情况，怀孕带给女性影响远胜于男性，就因为这个原因，大多数女性选择吃避孕药。

That’s why female pills will remain the principal hormonal birth control for the foreseeable future.
这就是在可见的未来，女性避孕药依然会是控制性激素的首要途经的原因。
