1.How long has it been since marriage without pregnancy is infertility? A couple of childbearing age who have lived together for more than one year, have a normal sexual life and have not used any contraceptive measures, but have not been able to conceive, is called infertility. Infertility is defined as the failure to obtain a viable baby due to miscarriage or ectopic pregnancy, although conception is possible for various reasons. If the male partner is infertile due to male causes, it is called male infertility or male infertility, and is customarily called male infertility. 2.What are the causes of infertility? Infertility factors may be in the female partner, male partner or both men and women. Female factors account for about 40%, male factors account for 30%-40%, and male and female factors account for 10%-20%. (1) Female infertility factors: Ovulation disorders and tubal factors are the most common factors. Ovulation disorder accounts for 25%-35%, which can be a common manifestation of different diseases, mostly seen in polycystic ovary syndrome (PCOS), premature ovarian failure, etc. Obstruction of the fallopian tubes or incompetence of the fallopian tubes account for about 50% of female infertility factors. It is mostly caused by diseases such as pelvic inflammatory disease (PID), appendiceal perforation, post-abortion infection, and endometriosis. In addition, uterine factors such as uterine malformation, submucosal fibroids, endometrial polyps, uterine adhesions, and cervical factors such as cervical inflammation can also cause infertility. (2) Male infertility factors: mainly abnormalities of semen such as azoospermia, oligospermia and weak semen, and abnormalities of sexual function such as impotence and premature ejaculation. (3) Factors in both men and women: immune factors such as Rh factor or ABO hemolysis and the production of various antibodies such as anti-sperm antibodies and anti-endometrial antibodies. If the cause of infertility cannot be confirmed by clinical system examination, it may be related to personal psychological factors (such as anxiety, tension, etc.), increased environmental and industrial toxins, long-term exposure to high-intensity radiation, etc. 3.Chinese medicine treatment of infertility There are many causes of infertility, and it can also be said that infertility is the result of many diseases, so the treatment should firstly clarify the main cause of infertility and the disease to which it belongs, and it is necessary to conduct relevant examinations.
