摄卵障碍机制较为复杂,临床报道尚少,现将我们在诊治不孕症中的体会,结合有关文献报道如下: 摄卵是指成熟的卵子排入腹腔后,输卵管伞端将卵子摄入输卵管壶腹部的过程,亦称拾卵。此过程是在神经体液和部分内生殖器共同协调作用下完成的。排卵期输卵管伞端接近卵巢表面,内膜纤毛活动增强,形成一定的虹吸力,在腹腔液的参与下,将排入腹腔的卵子迁移至输卵管壶腹部。因此正常摄卵主要有如下决定因素:①成熟卵子排入腹腔;②输卵管通畅(包括伞端),纤毛活动正常;③输卵管伞端与卵巢之间解剖关系正常;④输卵管伞端与卵巢之间无阻隔。以上诸因素中某一或一种以上因素发生障碍均可导致摄卵不能。其中第1条
Oviparous mechanism is more complicated, clinical reports are still small, now we in the diagnosis and treatment of infertility experience, combined with the relevant literature reported as follows: Ovulation is the mature egg into the abdominal cavity, the tubal umbrella side of the egg into the fallopian tube The process of ampulla, also known as picking up eggs. This process is carried out by a combination of nervous fluid and part of the genitalia. Ovulation tubal umbrella end close to the ovarian surface, endometrial cilia activity increased to form a certain siphon power, with the participation of peritoneal fluid, will be discharged into the abdominal cavity of the egg migrate to the fallopian tube ampulla. Therefore, the main determinants of normal ovulation are as follows: ① mature egg into the abdominal cavity; ② tubal patency (including the umbrella side), ciliary activity is normal; ③ tubal umbrella and the ovarian anatomy between the normal; ④ oviduct between the ovary No barrier. Barriers to one or more of the above factors can lead to inoperability. One of the first
