IVF is characterized by a high success rate, the possibility of repeated use of the remaining embryos, higher costs and an increased risk of complications for both mother and child. 1. The probability of pregnancy with IVF can reach more than 70 percent for women younger than 30 years old and about 60 percent for those younger than 35. 2. IVF sperm and egg fusion can form multiple embryos, which can be frozen and preserved for next time use. 3. The cost of IVF is around $30,000, and patients need to return to the hospital repeatedly, which is time-consuming and labor-intensive. 4. Because the embryos will be transferred 2 at a time, there is an increased risk of multiple births, preterm labor, hypertensive syndrome during pregnancy, and even the risk of ectopic pregnancy. IVF is suitable for female patients with ovulation difficulties and ovarian failure, suffering from uterus-related diseases, male patients with oligospermia and hypospermia, immune infertility, etc. It should be carried out after assessment by a specialized hospital.
