Are artificial insemination and IVF really the same? So, what is the difference between them? 1. The difference in definition? Artificial insemination is a method of artificially injecting male semen into the cervix or uterine cavity of a woman to assist in conception. IVF is a series of techniques using reproductive assisted technology to deliver sperm, eggs and embryos into the human body after in vitro manipulation to help infertile couples to have children, including artificial insemination, tubal gamete transfer and in vitro fertilization embryo transfer, etc. The pregnancy process of IVF is the same as the ordinary pregnancy process. 2.Difference in the applicable population Artificial insemination is mainly used for infertility caused by male, such as severe hypospadias, retrograde ejaculation, erectile dysfunction, azoospermia, oligospermia, weak spermia, and semen indefiniteness. Some female aspects of infertility can also be used for artificial insemination, such as vaginal spasm, small cervix, abnormal cervical mucus, and poor post-coital test. In addition, there are special cases such as immunological infertility, heterozygosity for the same autosomal recessive disorder in both spouses or autosomal dominant disorders in males, which can also be used to obtain pregnancy and avoid the birth of unhealthy offspring. IVF is mainly used for female infertility, such as severe tubal disease, endometriosis, immune infertility, the presence of anti-sperm antibodies in the male partner’s semen or the female partner’s cervical mucus, such as follicular non-rupture syndrome, etc. IVF is also suitable for a small number of male infertility patients caused by oligospermia, weak spermia, and teratospermia. IVF is also suitable for a small number of patients with male infertility caused by oligospermia, hypospermia and teratozoospermia. Those with hereditary diseases requiring pre-transplant diagnosis or infertility patients who cannot be cured can use IVF. 3. Success rate The success rate of IUI depends on the following four aspects. First, the predictability of ovulation is important. The more regular your period is, the higher the success rate of pregnancy. Secondly, men who have good sperm count and motility but cannot have intercourse have a significantly higher chance of successful IUI than men with abnormal sperm. Third, a history of endometriosis or pelvic infection or tubal disease reduces the success rate, but the success rate is higher in those who have had a previous pregnancy. Fourth, if the woman is too old (over 35 years), her chances of pregnancy are significantly lower. The success rate of IVF depends on a number of factors, one being the good or bad treatment of one’s own eggs, the good quality of the dip, the good quality of the sperm-egg union, plus the good environment of the uterus after implantation. However, there are many human factors involved, such as artificial egg retrieval, artificial culture and artificial implantation.
