The third-generation in vitro fertilization does not allow the selection of gender.

1. Can the gender be selected in the third-generation in vitro fertilization?

The third-generation in vitro fertilization, also known as preimplantation genetic diagnosis, refers to the process where doctors analyze some genetic materials of the embryo before transplantation to diagnose whether there are any abnormalities, and then select healthy embryos for transplantation. The purpose of this is to prevent the occurrence of genetic diseases. In this case, doctors can determine whether the embryo is male or female in the laboratory and then implant it into the female's uterus. However, the selection of fetal gender can only be used for medical needs. Although the third-generation in vitro fertilization can select the gender of the baby, most hospitals have abolished this technique, as it is illegal. Therefore, if the third-generation in vitro fertilization is used for transplantation surgery, the gender of the child cannot be chosen.

2. Suitable candidates

In vitro fertilization is usually suitable for people with ovulation difficulties, blocked ovulation channels, ovarian failure, asthenospermia, and other male or female groups.

3. Precautions

At the beginning of receiving in vitro fertilization, it is recommended that both men and women should take sufficient rest and maintain adequate nutritional intake. Sexual intercourse is prohibited during this stage, as it may affect the success rate of in vitro fertilization transplantation. In addition, during the process of in vitro fertilization, it is recommended that women strictly follow the requirements and procedures. Strict compliance with the doctor's instructions is required during this process. Generally speaking, the success rate of in vitro fertilization is quite high, so patients do not need to worry too much.
