If there is infertility associated with scanty menstruation, it is important to first identify the cause. It is necessary to consider whether the scanty menstruation is due to previous intrauterine procedures, such as a history of abortion, intrauterine device insertion or removal, which could have caused endometrial damage, intrauterine adhesion, or thinning of the endometrium. Hysteroscopy for diagnosis and treatment might be required. Additionally, possible endocrine issues should be considered. Blood should be drawn during the menstrual period to check for sex hormones, thyroid hormones, and others.
