不孕症的原因:不孕症和生育的环境因素
   什么是影响生育的环境因素?
 
  已知某些工业化学品,环境污染物和辐射会导致或导致不孕。例如,铅中毒一直与男性和女性的不孕症有关。
 
  癌症的化学疗法和X光疗法对精子和卵子有极大的毒性,并可能导致永久性不孕。美国的加州生育计划建议接受化疗的男性在治疗前储存精子。有时我们也能够在女性癌症治疗之前进行卵子取出,并冻结卵子或胚胎供以后使用。
 
  长时间浸泡在浴缸或热水浴缸中或长时间坐着(例如,卡车驾驶)和过度骑自行车会导致阴囊温度升高到足以损害精子生成。因为精子需要长达两个月才能成熟,冬季桑拿会影响早春的精子。发热性疾病(有温度的疾病)也可导致精子活动性显着下降,可能需要3-4个月才能恢复。运动中的极端努力也可以显着降低精子活力数小时。

  What are Environmental Factors that Affect Fertility ?
 
  Certain industrial chemicals, environmental pollutants and radiation are known to contribute to or cause infertility. Lead poisoning, for example, has long been associated with infertility in both men and women.
 
  Chemotherapy and x-ray therapy for cancer can be extremely toxic to sperm and eggs and can cause permanent infertility. Our California fertility program recommends that men who will be undergoing chemotherapy store their sperm before treatment. Sometimes we are also able to do egg retrieval before a woman's cancer treatment and freeze the eggs or embryos for later use.
 
  Long soaks in the bath tub or hot tub or long hours of sitting (for example, truck driving) and excessive bicycling can cause the temperature in the scrotum to increase enough to impair sperm production. Because sperm take up to two months to mature, winter saunas can affect the sperm of early spring. A febrile illness (one with a temperature) can also lead to a significant decline in sperm motility that may take up to 3-4 months to restore. Extreme exertions in exercise can also significantly reduce sperm motility for several hours.
