Introduction
1. Physiological factors: In females, the urethra is located in close proximity to the base of the bladder and the vaginal area; furthermore, pelvic organs—including the uterus and adnexa—have a particularly intimate anatomical relationship with the vagina.
2. Pathological factors: Conditions such as cervicitis, salpingo-oophoritis (adnexitis), and pelvic inflammatory disease (PID) may be implicated. Notably, during sexual intercourse, sudden, severe lower abdominal pain may indicate corpus luteum rupture.
Women may experience lower abdominal pain following sexual intercourse. There are numerous potential causes—some physiological, others pathological. During intercourse, certain positions or vigorous movements may trigger such discomfort; however, persistent or severe pain warrants careful evaluation to rule out underlying disease. So, what causes lower abdominal pain after sex? Below is an explanation of this issue.
What Causes Lower Abdominal Pain After Sex?
1. Physiological Factors
The female urethra lies in close proximity to the bladder base and vagina, while the uterus and adnexa—key pelvic organs—are even more intimately associated with the vaginal canal. Consequently, these structures are highly susceptible to external mechanical pressure and biological stimuli. During intercourse, vigorous penile thrusting may exert strong stimulation on the vagina, peritoneal cavity, and pelvic organs, resulting in abdominal pain. If the pain is mild and transient, no specific treatment or intervention is required—simply ensure adequate warmth and rest.
2. Pathological Factors
(1) Gynecological Inflammation
Conditions such as cervicitis, salpingo-oophoritis (adnexitis), and pelvic inflammatory disease (PID) may predispose women to lower abdominal pain during or after intercourse. Sexual stimulation—especially during orgasm—can induce uterine cervical contractions. Excessively vigorous or rapid thrusting, excessive depth of penetration, or direct impact on inflamed or diseased areas may provoke acute lower abdominal pain. This pain tends to persist beyond intercourse and does not resolve spontaneously. Affected individuals should undergo gynecological examination, pelvic ultrasound, and colposcopy to identify the specific type of inflammation and receive appropriate targeted therapy.
(2) Corpus Luteum Rupture
Sudden, severe lower abdominal pain occurring during intercourse may indicate corpus luteum rupture. During sexual activity, mechanical compression or vibration can cause a mature follicle or corpus luteum to rupture abruptly, leading to intense pain and intra-abdominal hemorrhage. Immediate medical evaluation is essential; management depends on clinical severity and may include conservative treatment or surgical intervention.
The above outlines the possible causes of lower abdominal pain following sexual intercourse. We hope this information is helpful.
