In clinical practice, if a progestin antagonist type of contraceptive is taken, it can cause genital malformations in the fetus, for example, it can cause masculinization of the genitals in female babies or hypospadias in male babies. Therefore, if this type of contraceptive is taken orally, it is recommended to terminate the pregnancy after conception. There are some birth control pills, such as a combination of estrogen and progestin, which at safe doses tend to have little effect on the fetus. Therefore, if you become pregnant after taking oral contraceptives, it is recommended to take the pills you are taking to the Eugenics Department for further consultation, mainly to find out exactly what type of pills you are taking and whether you need to give a termination of pregnancy.
