What Causes Lower Abdominal Pain After Intercourse?

Sexual intercourse is a common activity between married couples. While it often brings mutual pleasure, some women experience lower abdominal pain after intercourse. This discomfort not only causes physical distress but also raises concerns about potential health issues. So, what causes lower abdominal pain following intercourse? Below, we address this question.

Causes of Lower Abdominal Pain After Intercourse

1. Anatomical Factors

In females, the urethra and bladder base lie in close proximity to the vagina, while the uterus and its adnexal structures (e.g., fallopian tubes and ovaries) are even more intimately associated with the vaginal anatomy. These pelvic organs are thus highly susceptible to external mechanical pressure and biological stimuli. During intercourse, vigorous penile thrusting can exert strong stimulation on the vagina, abdominal cavity, and pelvic organs.

2. Excessive Force or Improper Positioning

Excessive force, overly intense pressure, or awkward positioning during intercourse may elevate intra-abdominal pressure in the female partner. This can impair intestinal motility and compress the uterus, rectum, and bladder under gravitational force—sometimes even triggering reverse peristalsis—resulting in paroxysmal abdominal pain.

3. Gynecological Inflammation

Lower abdominal pain after intercourse may stem from gynecological inflammatory conditions such as cervicitis, salpingo-oophoritis (adnexitis), or pelvic inflammatory disease (PID). Sexual stimulation—especially during orgasm—can trigger uterine cervical contractions. If the male partner’s movements are excessively vigorous, rapid, or wide-ranging, minor vaginal bleeding may occasionally occur.

4. Corpus Luteum Rupture

Sudden, severe lower abdominal pain during intercourse may indicate corpus luteum rupture. During sexual activity, mechanical compression or vibration may cause a mature follicle or corpus luteum to rupture abruptly, resulting in sharp, acute pain and intra-abdominal hemorrhage. Immediate medical evaluation is essential if this occurs.

The above outlines the possible causes of lower abdominal pain following intercourse. We hope this information is helpful to you.
