Artificial insemination is one of the assisted reproductive techniques (ART): a new technique developed at the intersection of obstetrics and gynecology, urology, genetics, and molecular biology, involving the manipulation of oocytes, sperm, and embryos to enhance fertility or improve pregnancy outcomes. It is a technique that involves the manipulation of oocytes, sperm and embryos to improve fertility or pregnancy outcomes. According to the route of sperm injection, it is divided into: 1) Intravaginal insemination (IVI) 2) Intracervical insemination (ICI) 3) Intrauterine insemination (IUI) 4) Intrauterine insemination (IUI) 5) Intrauterine insemination (IUI) 6) Intrauterine insemination (IUI) 7) Intrauterine insemination (IUI) 8) Intrauterine insemination (IUI) 4. Intrauterine insemination (IUI) 5. Intrafollicular insemination (IFI) 6. In vitro fertilization-embryotransfer (IVF-ET) In vitro fertilization-embryotransfer (IVF-ET) is the so-called first-generation IVF technology, the so-called second-generation IVF technology by single sperm intracytoplasmic injection (ICSI) and the so-called third-generation IVF technology by preimplantation diagnosis (PGD), as well as various new technologies derived and evolved on this basis. technologies. The term artificial insemination is commonly used to refer to artificial insemination in the narrow sense, where semen is injected into a woman by artificial means to assist in conception. Recently, there has been a lot of interest in “intrauterine insemination”; however, the results and outcomes are not promising. “Intrauterine insemination” does not necessarily increase the rate of conception. The injection of semen into the uterine cavity can not only cause intense stress, resulting in spasmodic contractions of the uterus, but also severe abdominal pain, nausea and even hypotension, which can lead to failure of conception. It may also activate the immune response, causing immune infertility and making it more difficult to conceive. There are many practical problems that need to be solved, so beware of taking a detour. Artificial insemination is now quite common in the world. It is estimated that about 5,000-10,000 artificially inseminated babies are born each year in the United States. For example, in 1980, Los Angeles, a 41-year-old unmarried female psychologist with a Nobel laureate contributed semen pregnancy, gave birth to a baby boy, known as the “Nobel baby”. Artificial insemination in Europe and the United States has caused a number of social problems: the United Kingdom has a case of “unethical doctor, the birth of three thousand”; the United States also has a similar case: a doctor used his own semen to inseminate hundreds of people, and was sentenced to more than 200 years in prison. Artificial insemination has become quite widespread in Taiwan Province of China. In recent years, more and more work has been done in this area in mainland China. However, the Chinese Ministry of Health clearly states that medical personnel are not allowed to perform assisted reproduction techniques on single women, including the use of sperm banks. Sperm banks everywhere must undergo rigorous inspection, be approved by the Ministry of Health and be reviewed regularly.
