IVF refers to in vitro fertilization. The differences between artificial insemination and in vitro fertilization are: definition, indications, and technical difficulty. 1. Different definitions Artificial insemination refers to a method of injecting semen or sperm suspension after in vitro separation into the female reproductive tract by artificial means to cause pregnancy. In vitro fertilization (IVF) refers to a method in which the sperm and eggs of an infertile man and woman are taken out of the body, fertilization is completed in an in vitro culture system, and the embryos are developed into embryos, which are then transferred into the uterine cavity to develop. 2. Different indications The indications for artificial insemination are: men with semen abnormalities, women with low cervical mucus secretion or mucus abnormalities, women with endometriosis, and unexplained infertility. IVF is divided into first generation IVF, second generation IVF and third generation IVF. The first generation of IVF is suitable for those who have blocked fallopian tubes; the second generation of IVF is suitable for men with severe oligozoospermia; and the third generation of IVF is suitable for those who one of the spouses may have hereditary risk diseases. 3. Different technical difficulties Artificial insemination is relatively easy. IVF technology is relatively more difficult, and it is also the top technology in the field of reproductive medicine. In addition to the above differences, there are also different operation procedures and different costs.
