正常男子一次射精虽然排出数千万甚至高达2亿左右个精子只有最多几十个能进入受精区

精子的199999999种死法—— 老死篇

附睾是精子的储藏库从睾丸出来的精子必须在附睾储藏一定时间后才具有让卵子受精的能力

—— 累死篇
精子身长只有60微米而阴道长度有8㎝8cm = 80000微米再加上还要突破宫颈粘液等“障碍”

—— 酸死篇
阴道是酸性坏境对于微生物和精子而言这样的环境完全无法生存
http://mmbiz.qpic.cn/mmbiz_png/sm80ic7WAFYicAEd9BzicJEACQiaNCDw602ZbqXGpiavFyk4kTuZFrB1loRPXe5I9OA1X6prABUCZVymIAITbRwDeJQ/640?wx_fmt=gif&tp=webp&wxfrom=5&wx_lazy=1
虽然精液中含有某些碱性物质(如精囊腺的分泌液)能够在精子进入阴道时起到一定的中和作用http://mmbiz.qpic.cn/mmbiz_png/sm80ic7WAFYicAEd9BzicJEACQiaNCDw602ZADlq8gK30FVOQ6AaNrDyJnRDenI8BOjETvaTbW90rcWcyd096S0oaQ/640?wx_fmt=gif&tp=webp&wxfrom=5&wx_lazy=1
—— 晕死篇
女性每次只排出一个卵细胞两侧卵巢交替排卵这对精子来说可太悲催了——两根输卵管"岔路口"上还没有指示标志总会有一部分小蝌蚪跑错道踏上了永远也不可能遇上卵子MM的不归路

—— 淹死篇
被唾液淀粉酶淹死或被大肠杆菌吃掉......

—— 被尿憋死篇
当发生逆行射精时精子就会进入膀胱被尿液泡死
逆行射精是指性交时能达到性高潮且有射精感，但无精液从尿道排出，性交后尿液中有精子和果糖。即精液逆行流入膀胱内。主要是由于膀胱颈不能关闭或膜部尿道阻力过大所致。
