男人连续射精……………恐怖后果
如今日本夫妇性生活的次数越来越少。于是不少人大声疾唿:让我们回到一天多次性爱的年轻时代去吧!不过与此同时,几位日本性学专家却指出,性生活好不好,不能单纯以次数论。
东京山泌尿专科医院的吉川优医生指出,在正常性交时,约有2—4亿个精子射到女性宫颈和阴道后穹窿处,在女性宫颈分泌物的帮助下,精子活动能力增强,成为男性生育能力健康的重要表现。但科学家们研究发现,如果一个男子在6小时内接连射精4次,那么持续一天之后,男性射出的精液中,就再也找不出一个精子了。
“对于需要生育后代的年轻夫妻来说,这可不是什么好事。
缺失精子,会对男性睾丸的正常生理功能形成刺激,甚至影响今后正常精子的生成;而没有足够数量、高品质的精子,仅仅由前列腺等部位大量分泌出体液,还很容易让男性出现脱水、虚脱的状况。”
要给性生活频度确切地下定义是困难的,因为个体的差异很大,既使是同一对夫妻在不同情况下,性生活频度亦不尽相同,当然新婚夫妇有较频些的性生活是可以理解的。
适度的性生活应是以房事后次日无精神不振、头婚、疲倦不适等为度,做任何事都不能过头,过了头就会产生各种各样副作用,对身体产生危害,所以适度的掌握性生活频度是很有必要的。
性生活过度主要表现为:面容憔悴,形体消瘦,精神倦怠,萎靡不振,头重脚轻,周身无力,心跳气短,虚汗淋漓,失眠多梦,不思饮食。当有以上“信号”出现时,即已告诉你,性生活已经使你“超负荷”了,必须立即调整。
为了防止这些信号出现,不单是适当节制房事次数,还要做到“两不”:
(1)强劳动后不宜房事,否则体力过度消耗,就会损伤“元气”,贻害不浅。
(2)酒后不房事。中医曾说“醉以入房,以欲竭其精”。意思是在醉酒情况下行房事,将影响健康,大损肾气,导致阳痿、早泄。
