Easier hygiene. Circumcision makes it simpler to wash the penis. Washing
beneath the foreskin of an uncircumcised penis is generally easy, however.
Decreased risk of urinary tract infections. The overall risk of urinary
tract infections in males is low, but these infections are more common in
uncircumcised males. Severe infections early in life can lead to kidney

2。性活动和心脏病关系的研究，基本都局限在心梗；
3。一般人群中，性活动增加心梗发病率是肯定的，但是relative risk 不高；伟哥服
用者，性活动增加心梗发病率则相对严重，而且大部分没合用nitrate；

发帖数: 7856 | 28 英语“morning glory”是什么意思？
查字典，是牵牛花的俗称。不过哪天一堆男人聚在酒吧聊到morning glory，他们
肯定不是在交流园艺心得。牵牛花凌晨四点开花，男人的morning glory就是晨勃。晨
勃的英文学名是Nocturnal Penile Tumescence（夜间阴茎粗大--夜大阴），最常见的
叫法是morning wood，直译应是“晨杵”--古语说“断木为杵”，国内聪明的网友译为
“陈伯伯”，对看“大姨妈”。
齐泽克曾有一问：世界上什么东西最轻？自答：鸡鸡，因为光有想法就能把它举起
来。他编这个段子时陈伯伯不在：其实连想法都不用，做着梦就能举。
陈伯伯的科学道理到现在还没有完全查明，比较可靠的是观察纪录：它在夜间快波
睡眠时发生，一夜能有四五次，凌晨之际牵牛花开持续时间一般一两小时，可以长达几
个钟点。很多人都有孤阳独亢掀翻被窝顶着油门起床的经验。
有一派哲学以为任何事物发生都会有它的用处。按照国外一些认死理的朋友解释，
早上起来夹着根晨杵看似不雅，实则有用。你忙着梳洗，刷牙剃须时，可以把洗脸毛巾

The World Health Organization (WHO) recommends considering it as part of a

Circumcision reduces the incidence of HSV-2 infections by 28%,[17] and is
associated with reduced HPV prevalence[18][19][20][21] and a reduced risk of
both urinary tract infections (UTIs) and penile cancer.[8] |
