What Causes Lower Abdominal Pain After Intercourse?

Some women report experiencing lower abdominal pain after intercourse—perhaps a brief, sharp pain lasting only a few seconds, which resolves spontaneously by the following day. So, what causes lower abdominal pain after intercourse?

What Causes Lower Abdominal Pain After Intercourse?

Lower abdominal pain following intercourse is related to female anatomy. In women, the urethra and base of the bladder lie in close proximity to the vagina, while the uterus, fallopian tubes, ovaries, and other pelvic organs have an even more intimate anatomical relationship with the vaginal canal. These structures are highly susceptible to external mechanical pressure and biological stimuli. During intercourse, vigorous penile thrusting exerts strong stimulation on the vagina, peritoneal cavity, and pelvic organs, causing the woman to breathe rapidly and involuntarily tense her entire body—particularly during orgasm. This physiological response may itself induce discomfort or mild pain; however, because attention is typically focused elsewhere, the pain often goes unnoticed during intercourse. Instead, it becomes apparent only afterward as lower abdominal discomfort. In most cases, this post-coital pain resolves spontaneously and rapidly.

If the male partner applies excessive force or pressure during intercourse—or if positions are suboptimal—it may increase intra-abdominal pressure in the female partner, potentially interfering with bowel function and exerting gravitational compression on the uterus, rectum, and bladder. This may occasionally trigger retrograde peristalsis, manifesting as paroxysmal (intermittent) abdominal pain.

During intercourse, it is essential to maintain both environmental hygiene and personal genital cleanliness. Unhealthy sexual practices can introduce pathogenic bacteria into the body, potentially triggering infections or other gynecological conditions. Therefore, for the health of both partners, thorough cleaning of the external genitalia prior to intercourse is strongly recommended. We hope this information is helpful to you.
