Hypogonadotropic hypogonadism is one of the causes of infertility. In women with hypogonadotropic hypogonadism both follicle-stimulating hormone and luteinizing hormone are required to induce optimal follicular growth and steroidogenesis. We described a case of singleton pregnancy in a 38-year-old patient, presenting with primary hypogonadotropic amenorrhea and empty sella syndrome, treated with human menopausal gonadotropins and performing intrauterine insemination in first attempt. This therapy led to maturation of two follicles and one of them was fertilized. A singleton pregnancy ensued and a normal infant was delivered by cesarean section.
