體外射精為什麼失敗率高
不是在於許多人所說的
在做愛時精子會流出一點所以會中獎
如果這麼容易中獎
又怎麼會因為精蟲過少而不孕?
體外射精失敗率高是因為許多人自以為可以控制射精的時間
通常來不及拔出來就射了
才會導致懷孕
所以才會說體外射精的失敗率是50%
只有極少數會因為單純抽差產生的些微精液導致懷孕
精子射出後並不是全都會爬到子宮
首先就會碰到第一個關卡子宮頸
子宮頸也不是大家想像的那樣跟陰道平行
事實上它是跟陰道有一個角度接近垂直的
所以有些人說可以頂到子宮頸
除非你的那根會轉彎
重點是
子宮頸會伸出觸爪把存在儲精槽的精子吸附上來
並不是直接通過!!
最後能通過子宮頸的精子早已經是少數
再來
並不是跟很多人想的ㄧ樣
ㄧ個精子碰到卵子就會受孕
卵子要受孕
首先精子碰到卵子後要分泌一種能分解卵子外面包覆的膜的東西
光靠一個精子是不足以讓膜分解而受精
起碼都要一定數量以上才有可能分解後受精
所以精子量不夠
很難有機會受孕
除非你的精子活力超強
否則受孕的機會並不大
此篇不是鼓勵體外射精
而是要矯正一些認知上的錯誤
戴保險套還是最安全的方法~~
