A man’s genes are not left behind after an abortion. A man’s genes can only remain in a woman’s body through the combination of sperm and egg cells. Generally, the fertilized egg loses its effect after abortion and becomes embryonic tissue, which is discharged from the body through the administration of medication, so there are no man’s genes left behind after abortion. Moreover, unfertilized sperm survives in a woman’s uterus for a maximum of two to three days and outside the body for only about forty-five minutes. In addition, everyone’s genes are fixed and will not be affected by others, so there is no such thing as leaving behind a man’s genes after an abortion. Patients are advised to take contraceptive measures. Multiple abortions may lead to infertility, which will have a certain impact on a woman’s fertility. And you should also go to the hospital for regular checkups after abortion in order to prevent the occurrence of diseases.
