在现实生活中,有人贪婪色情,纵欲过度;也有人视夫妻性生活如“洪水猛兽”,在生儿育女后就采取禁欲态度。其实,从医学角度来看,这两种方法对人体都有害无益。 纵欲不利优生 新婚夫妇性交频繁是自然的,然而性生活过度不利优生。由于男方频频排出精液,而精于数目不足,多有未发育成熟者,这样未成熟的精于进入女性阴道,使得受孕率大大降低。即使受孕,与卵子结合成质量低下的受精卵,也容易引起流产。幸免的胚胎,由于先天不足,或有染色体缺陷,胎儿也有可能发育成为畸形,给家庭酿成悲剧。在妻子怀孕期间,丈夫不节制性生活,还易导致流产。 In real life, some people greedy pornography, over-indulgence; others regard sexual life as husband and wife, such as “a scourge of beasts,” taking an abstinence attitude after having children. In fact, from the medical point of view, these two methods are harmful to the human body. Incontinence poor eugenics Newlyweds frequent sexual intercourse is natural, however, excessive sexual life adverse eugenics. Because men frequently discharge semen, while the lack of skilled in the number of more than immature, so immature skilled in the female vagina, making the pregnancy rate is greatly reduced. Even if the pregnancy, combined with the egg into the poor quality of fertilized eggs, but also easily lead to miscarriage. Spared embryos, due to birth defects, or chromosomal defects, the fetus may also develop into a deformity, causing tragedy to the family. During the wife’s pregnancy, her husband does not control her sex life and can easily lead to abortion.
