Syphilis patients can have children. After regular treatment, syphilis patients can conceive and bear children normally. After being treated for syphilis, the RPR test can become negative, indicating that there are no live syphilis spirochetes in the body and no infectivity. At this point, pregnancy is not affected. Some pregnant women, after treatment, can block mother-to-child transmission and prevent the spread of syphilis, which is a systemic sexually transmitted disease caused by infection with the syphilis spirochete. If a woman infected with syphilis becomes pregnant without undergoing standard syphilis treatment, the syphilis spirochete can infect the fetus through the placenta, leading to fetal disease. Some may experience stillbirth, miscarriage, premature birth, or even the birth of a child with congenital syphilis. Therefore, it is recommended that syphilis patients undergo standard treatment to cure syphilis before becoming pregnant.
