During the consultation, we found that many patients often confuse artificial insemination with IVF and do not understand the difference between the two, so here is a brief explanation for patients.
Artificial insemination is a technique to assist pregnancy by placing processed semen into the female reproductive tract through non-coital means. According to the source of sperm, it is divided into husband insemination or donor insemination.
Indications for artificial insemination.
Male partner factors.
1. Abnormal factors that prevent sperm from entering the vagina during intercourse: such as severe hypospadias, retrograde ejaculation, etc.
2. Mental/nervous factors: such as impotence, premature ejaculation, non-ejaculation, etc.
3, immune infertility: autoimmune antibody production due to some infections, trauma and other factors.
4. Semen abnormalities (mild to moderate): oligo-weak teratozoospermia, low semen volume, incomplete semen liquefaction.
Female factors: (prerequisite: normal tubal examination)
1, the presence of factors that hinder the operation of sperm in the female reproductive tract: such as narrow vagina and cervix, highly flexed uterus, etc.
2, cervical factors: low cervical mucus, after cervical conization, electro-ironing or cryotherapy, cervical polyps or fibroids, etc.
3.Immune infertility: the presence of anti-sperm antibodies.
4. Unexplained infertility.
In vitro fertilization-embryo transfer (IVF-ET), as it is commonly known, is a technique to assist pregnancy by removing the sperm and eggs of the patient couple outside the body, fertilizing them in a Petri dish, developing into embryos and then transferring them into the patient’s uterine cavity. Depending on the patient’s condition, IVF can be subdivided into 1st generation (conventional in vitro fertilization), 2nd generation (microfertilization technique) and 3rd generation (pre-implantation genetic diagnosis of embryos).
IVF indications.
1. Gamete transport disorders caused by tubal factors;
2. Endometriosis;
3. Intractable polycystic ovary syndrome;
4.Severe oligospermia or azoospermia in men;
5.Unexplained infertility;
6.Immune infertility.
