Coitus before implantation will not improve implantation and sexual intercourse is not recommended. Infection after coitus can have an impact on the transplant. If anything goes wrong, it is likely that the transplant will fail. Therefore, coitus prior to transplantation will not improve implantation. Before performing the transplant, keep the perineum clean and change clean underwear in time, have a good routine and enough sleep. Stay in bed and try to avoid strenuous exercise or heavy lifting to avoid abnormalities. Before the transplant must pay attention to take precautions, women should pay attention to clean the vulva, timely gynecological examination as well as leukorrhea test, to avoid causing infection.
