[討論] 原來保險套也沒比外射好多少...已回收
常常看到板上在討論不同避孕方法的安全機率
但常常會覺得很困惑那個99%到底是什麼
最近看到這一篇

http://www.nytimes.com/interactive/2014/09/14/sunday-review/unplanned-pregnancies.html
裡面分析了各種避孕方式的十年懷孕風險
正確使用男性保險套十年懷孕的風險有18%
而正確的計算安全期及體外射精的風險則為26%和34%
沒想到保險套竟然沒比那些傳統覺得不可靠的避孕方式好多少
就連男性和女性結紮十年也分別有2%和5%的懷孕機率
結紮後還懷孕不會覺得怪怪的嗎...
