An overgrown penis does not usually cause the corpus luteum to rupture in women. The corpus luteum is a structure developed by follicular cells in the female ovary after ovulation, rich in blood vessels, and its main function is to secrete sex hormones. Rupture of the corpus luteum usually occurs in women of childbearing age with active ovarian function, and the main causes include spontaneous rupture, i.e., the proliferating blood vessels first rupture and bleed internally, and then the pressure increases, resulting in rupture of the corpus luteum; external rupture, e.g., trauma to the lower abdomen, extrusion during gynecological examination and palpation, straining to have a bowel movement, or intense sexual intercourse, etc., which may also lead to the rupture of the corpus luteum. Therefore, an overgrown penis generally does not cause luteal rupture in women and is not directly related to luteal rupture in women. Patients with luteal rupture may first experience pain in one side of the lower abdomen, which may be accompanied by nausea, vomiting, frequent urination and a sensation of anal swelling. Secondly, due to the large amount of internal bleeding, it may lead to hemorrhagic shock appearing pale, cold limbs (cold limbs, even cold to the elbows and above the knees), and a drop in blood pressure. Therefore, women should pay attention to avoid external injuries such as impact on the lower abdomen in daily life, and should not be too intense during sexual intercourse, and once suspected of luteal rupture, go to the hospital immediately to avoid delaying the condition.
