17 Feb About 65 percent of the injected eggs are fertilized, and about a third of the women to whom they are transferred . By interfering with sperm.
Description:In this chapter I will describe the arduous journey that sperm must make through the female genitals to reach the egg, as well as the simultaneous adventure of the egg during which it matures to become genetically ready for fertilization, erupts from the ovary, and gets grabbed by the fallopian tube, fertilized, and then hustled along into the womb at exactly the right moment to implant. Failure of the sperm or egg to make an important connection anywhere along this complicated itinerary will prevent pregnancy from occurring. At the end of this canal, in the deepest recess of the vagina, is a structure called the cervix, which is the entrance to the womb, or uterus. The uterus is a hard, muscular, pear-shaped structure with a narrow, triangular cavity inside, so small that it would barely hold a teaspoonful of fluid. Yet this is where the fertilized egg must implant itself and grow during the next nine months into a full-size baby.
