Brief Report Treatment of infertility and menopause in a patient with multiple sclerosis affecting the pituitary stalk: a case report.

Background: Multiple Sclerosis (MS) is an immune-mediated inflammatory disease characterized by demyelination of the CNS that affects women in their child-bearing years. There has been no absolute data to suggest infertility in this population; however, women with MS may exhibit decreased fertility due to various etiologies. Furthermore, their transition into menopause presents unique aspects in patient care.

Methods: We report a case of a 38 year-old female with a diagnosis of MS with subsequent secondary amenorrhea and primary infertility. Multidisciplinary work-up with was consistent with hypothalamic hypogonadism secondary to MS affecting the pituitary stalk. She was treated for infertility in our clinic as well as management of her menopausal symptoms.

Results: The patient conceived triplets after 2 cycles of ovarian stimulation with injectable gonadotropins and intrauterine insemination. She underwent fetal reduction to twins. After completion of childbearing, she was treated for menopausal symptoms with various hormonal therapies and ultimately remained on oral conjugated estrogens with no symptoms.

Conclusion: To our knowledge, this is the first report of infertility caused by suspected MS involvement of the pituitary stalk. In this patient population, infertility treatment can be successful with gonadotropins and alleviation of menopausal symptoms can be achieved with hormone replacement.
