Introduction
Sexual intercourse refers to coitus. Lower abdominal pain after intercourse may be caused by frequent intercourse or vigorous movements, leading to abdominal distension and discomfort. It could also result from acute bacterial infection of the pelvic cavity, in which inflammatory stimulation causes pelvic congestion and spasmodic pain due to uterine contractions during intercourse. Additionally, it might be due to rupture of the corpus luteum during intercourse, causing lower abdominal pain accompanied by symptoms such as vaginal bleeding.

Sexual intercourse, clinically referred to as coitus, may be followed by lower abdominal pain. This pain could result from physiological factors or pathological conditions such as acute pelvic inflammatory disease or corpus luteum rupture. The specific causes are analyzed as follows:

I. Physiological Factors

During coitus, excessive frequency or overly vigorous activity by the male partner may cause uterine contractions and pelvic congestion, leading to lower abdominal discomfort or pain. Usually, no special treatment is required. Reducing the frequency of intercourse and getting adequate rest for a short period can help alleviate symptoms.

II. Pathological Factors

1. Acute Pelvic Inflammatory Disease (PID)

When the pelvic region is infected by acute pathogens, inflammation can lead to pelvic congestion. During intercourse, increased uterine contractility may trigger spasmodic abdominal pain. It is recommended to take medications such as metronidazole tablets, doxycycline capsules, or amoxicillin capsules under medical supervision to control the infection and relieve symptoms.

2. Corpus Luteum Rupture

Excessively intense movements during intercourse may cause rupture of the corpus luteum, resulting in lower abdominal pain and possibly accompanied by vaginal bleeding. Prompt hospitalization is necessary; surgical removal of the ruptured corpus luteum, evacuation of accumulated blood, and suturing are typically required to resolve the condition.

In addition, uterine fibroids may also be a possible cause. If symptoms persist without improvement, timely medical consultation is essential.
