A successful pregnancy is the discharge of sperm into the vagina after sex, then the sperm passes through the cervical canal into the uterine cavity, reaches the fallopian tube, wanders in the fallopian tube, and waits for an egg. It meets the sperm to form a fertilized egg, which is then sent to the endometrium to be planted. It absorbs nutrients and grows on the fertile soil of the endometrium. From the perspective of a successful pregnancy process, the reasons for often not getting pregnant can be analyzed from four aspects: first, whether the sex life is right, or whether the sperm quality is good, this is the first common Questions; second, is the soil in the uterine cavity thick enough and fertile enough; third, whether the fallopian tubes are unobstructed; fourth, whether the ovaries are ovulating. In addition to anatomical structure, there are other reasons, such as genetic chromosomal problems, and some immune factors. In short, the causes of infertility are analyzed from these six aspects.
