With the increased pressure of life, infertility has become a common problem for modern couples. According to statistics, about one in ten couples and families are suffering from “inability to carry on the family line”. Treatment of infertility should be carried out with a clear understanding of the cause. Because of the complexity of the causes and the fact that infertility often occurs as a result of multiple factors, treatment options are diverse. Today, we will put aside traditional treatment methods and focus on artificial insemination, which is one of the wonders of modern medical technology. Artificial insemination, as the name suggests, is a method in which semen is removed by masturbation, washed by special instruments and upstream to remove some impurities, inflammatory and immune cells, bacteria and dead or weak sperm from the semen, and then high-quality semen is injected into the female reproductive tract through a specially constructed container to unite the sperm and egg. The technique of artificial insemination has gone through several stages, but the more mature method is now recognized as intrauterine insemination, in which semen is placed directly into the uterine cavity. The fertilization rate is about 20%. It can also be divided into ejaculate insemination and donor insemination. It is suitable for infertility caused by mild weak spermatozoa in men, semen non-liquefaction, sexual intercourse and ejaculation disorders, severe inflammation of the cervix in women, and the presence of anti-sperm antibodies in the couple. 1.The indicators of the husband’s semen examination are within the normal range, but due to malformation of male and female reproductive organs or sexual dysfunction, such as impotence, premature ejaculation, non-ejaculation and retrograde ejaculation in men, or narrow vagina, scar adhesion in the vagina, heavy erosion and flexure of the cervix causing sperm passage obstruction in women. 2, the husband’s semen quality is poor, such as sperm count less than 0.2 billion/ml, or sperm motility rate less than 40% and poor semen liquefaction, too few sperm, sperm malformation rate, etc., can be pretreated beforehand, such as concentrating, adding enzymes to promote semen liquefaction, washing, upstream to improve the quality of semen, and then artificial insemination to increase the chance of conception. Because of ethical and sociological problems, artificial insemination by sperm donation is strictly controlled by the state, and only regular hospitals equipped with sperm banks can carry out the procedure nationwide. The following are some of the most common types of insemination The mystery of artificial insemination has been lifted and it is believed that more and more couples will use this technique to achieve a healthy pregnancy. However, not all infertility cases can be artificially inseminated, and even if it is artificial insemination between spouses, the indications should be strictly selected in order to receive better results. Nowadays, the technology of artificial insemination is very mature and perfect, the success rate is high, the cost of a single treatment is low, and the number of ovulation-promoting drugs used in the cycle is small, which reduces the burden on the ovaries and the occurrence of complications.
