1. Bilateral tubal nowhere: Due to inflammation, tuberculosis or endometriosis, congenital absence of fallopian tube or abnormal peristalsis caused by ectopic pregnancy, sperm and eggs cannot meet. IVF technology has built a bridge for these patients. It can be said that bilateral tubal nowhere is the absolute indication of IVF.
2. Immune infertility: Semen is fertilized in vitro after washing to avoid interference of immune factors.
3. Male factor: After semen is washed and concentrated, it can be determined whether it has the ability of insemination in vitro.
4. Unexplained infertility: If no obvious cause is found under the current examination conditions, other patients with treatment failure can apply in vitro fertilization and embryo transfer techniques.
Relatively speaking, the requirements of some foreign countries are not so much, so more people choose to go to Southeast Asia such as Malaysia and Thailand.
