Introduction
There is a possibility of pregnancy with withdrawal (coitus interruptus), usually due to residual semen. Although withdrawal can reduce the chance of pregnancy to some extent, it is still possible for a small amount of semen to enter the vagina—either because the prostate is stimulated during intercourse, producing pre-ejaculate that may contain sperm, or because withdrawal occurs too late—potentially leading to unintended pregnancy.
There is a possibility of pregnancy with withdrawal (coitus interruptus), usually due to small amounts of semen remaining in the vagina.
Withdrawal is considered a form of contraception, typically involving pulling the penis out of the vagina before ejaculation to prevent semen from entering the female reproductive tract. While this method can reduce the chance of pregnancy, it is not entirely reliable. During sexual intercourse, the prostate may secrete pre-ejaculate fluid containing sperm, or ejaculation may occur slightly too late, resulting in semen entering the vagina and potentially causing pregnancy.
If symptoms such as nausea, vomiting, or excessive sleepiness occur after sexual intercourse, it is recommended to promptly visit the obstetrics and gynecology department at a hospital to determine whether pregnancy has occurred and to follow medical advice accordingly.
