<p>Dysmenorrhea is pain in the lower abdomen that occurs due to increased production of the<br>hormone prostaglandin. Adolescent menarche is the age range that often experiences pain<br>during menstruation. Complaints related to dysmenorrhea in women are often heard. The<br>aim of preparing this manuscript is to determine the physiology of the uterus and its<br>relationship to pain during menstruation or dysmenorrhea. The research method used was<br>a literature review by collecting journals by entering three keywords, namely uterus,<br>dysmenorrhea and menstruation in the Google Scholar database with Publish or Perish as<br>a data collection tool. As a result of data collection, there were 20 journals that were<br>relevant to the themes and subjects discussed. The results of a literature study found that<br>dysmenorrhea is caused by increased stimulation of the hormone prostaglandin in the<br>uterus which causes contractions in the uterine muscles to become stronger, resulting in<br>pain in the lower abdomen that spreads to the waist and thighs. Dysmenorrhea is not<br>dangerous, but can hinder activity.</p>
