没有发射出去的精子在睾丸里被重新吸收掉。所以输精管结扎的人不需要拖着巨蛋在地
上蠕动。
Although sperm are constantly being made within the testicles, should the
man not ejaculate for some time, his testicles won't explode. The
spermatozoa are simply re-absorbed into the body. This is important for
vasectomy patients because they simply have their 'tubes cut' and sperm is
still produced. Should excess sperm not be absorbed, it would not be long
before the patient's testicles were dragging along the ground.
不要愚昧地以为你是游得最远的一个。其实有人游得更远，一直游到了输卵管的末端，
然后就漏到了妈妈的腹腔里，因为输卵管末端不是封死的。换句话说，在大街上行走的
当代女性肚子里可能会有很多精子正游走于各器官的表面。当然最终它们都被妈妈当作
养分了。
Once sperm cells reach the end of the oviducts they are free to swim out of
the end of the tube and into the body cavity, where they are eventually
destroyed. So many women walking around today will have sperm cells swimming
around the interstitial fluid that surrounds their body organs. The female
reproductive tract does not finish in a dead end.
跟动物比
Animal facts
Ever thought about how humans compare with the rest of the animal kingdom
when it comes to sperm production?
公人一次发射4000万到5亿个半人。公羊发射950亿。
We can produce between 40 million and 500 million sperm in a good
ejaculation. A ram regularly releases 95 billion, which is approximately
1000 times more.
公人一天发射3到4次。公狮子不能全年发情，但是发情的时候每天可以有75次。
A human male can usually manage sex up to three or four times a
day. A lion can manage it seventy five times a day during the mating season.
公人一次发射2-5毫升液体。一个猪可以轻松制造一升。
When a man ejaculates he generally produces between 2 and 5
millilitres of sperm (about the same volume as a large teaspoon would hold).
A pig routinely manages one litre which is 200 times as much.
一些果蝇的精子体长可以达到父亲体长的20倍。如果人类有这种能力，那就相当于从鸡
鸡里甩出一条40米长的大蛇。
Our sperm cells are microscopic - we cannot see them with the
naked eye. On the other hand some diminutive fruit fly species produce sperm
cells that are 20 times their total body length. Imagine how it would feel
for a minute. It would be like a man producing a python about 40 metres long
from their penis. Ouch!
人类的精子通常30%-70%是会游泳的，老鼠的100%会游泳。
In a man's sperm sample something like 30 to 70 percent of our
sperm cells are motile (that is, they move with purpose). In rats or mice
all the sperm cells will be motile.
黑猩猩的蛋蛋跟身体大小的比例很大，大猩猩的蛋蛋跟身体比例很小。原因是黑猩猩特
喜欢做爱。
Generally, testicle size goes up with body size, but did you know
that chimps have huge gonads relative to their body size, whereas a gorilla'
s gonads are tiny. Apparently it's all down to lifestyle: chimpanzees are
promiscuous, gorillas are not.

这个精子被妈妈当养分吸收的翻法很不妥当嘛。谁是谁的妈妈呀？
说起狮子，我倒想起一个事情。有次去动物园，看见公狮子正发情和母狮子 xx，游客
或摄像或拍照，一起度过了几分钟愉快的时光。完事之后站在边上摆柜台介绍动物知识
的管理人员告诉我们，不知道为什么那头公狮子还有性趣，因为它已经被 fix 过了。
