Lower abdominal pain

Introduction Lower abdominal pain refers to lower abdominal pain caused by pelvic organic or functional lesions. It is one of the common complaints of gynecological infertility patients. The pain in the lower abdomen is transmitted along the sensory nerves of the sympathetic and parasympathetic nerves. Each genitalia is sensitive to pain. The perineum, vulva, and lower vagina are very sensitive to pain, while the upper vagina is relatively insensitive. The cervix is also relatively insensitive, and dilatation of the cervix can cause intense pain in the deep pelvic cavity. The uterus is insensitive to the isthmus. When the uterus compresses the nerve endings in the cervix, the uterus contracts with pain. The ovaries are not sensitive to many stimuli but are sensitive to squeezing movements during double-checking. When the ovarian parenchyma swells faster, it can cause pain. The fallopian tubes are sensitive to cutting, crushing, pressing and touching movements.
