description Disclosure: S. Ahsun: None. P. Lekprasert: None. K.K. Win: None. Introduction: As per the recent data there is an association between low levels of testosterone in men and the risk for multiple sclerosis (MS). Most recent practice involves checking testosterone levels for male patients with newly developed MS and treating with testosterone supplementation if levels are low. CASE PRESENTATION: A 65-year-old male with medical history of multiple sclerosis, prediabetes, hypogonadism, squamous cell carcinoma of left ear, thyroid cancer (unknown type) status post total thyroidectomy and radioiodine therapy; presented to our endocrine office for an initial visit. Patient had been following with Endocrinologist at different state in the past and did not have much of his prior records since that practice closed. He has been on 150 mcg of levothyroxine and his TSH was stable at 1.2 (0.4-4.5 mIU/L). He also had a history of hypogonadism and had been on testosterone supplementation since the age around 50. Patient did not know the underlying cause for his hypogonadism. He has 3 biological children and the youngest one is 26 years old. He had been off of testosterone therapy for 3 months prior to our initial visit. We did some workup which showed total testosterone level of <20 (250-1100 ng/dL). Free testosterone 2.2 (46-224 pg/mL). FSH and LH levels were elevated at 27.1 (1.6-8 mIU/mL) and 17.3 (1.6-15.2 mIU/mL). Prolactin level was 5.1 (5.2-26.5) ng/mL. These labs were consistent with Primary hypogonadism. Repeat testing was done and the patient had redemonstration of very low testosterone levels. Further checking of the karyotype analysis revealed normal male karyotype testing. His physical exam showed normal sized testicles at 20 cc and no gynecomastia. Body hair distribution was normal but there was decreased shaving frequency with decreased muscle strength. Patient never had any chemotherapy or the radiation therapy to the pelvic area. No known history of chronic infection or trauma. Currently, he is on Ocrelizumab for Multiple Sclerosis. His testosterone level is now in the normal range with the testosterone therapy after the work up. CONCLUSION: As per the above case, our patient has an interesting presentation of primary hypogonadism with multiple sclerosis. He has no known reason for his primary testicular failure. We know that testosterone deficiency has been linked to development of MS and MS can lead to secondary hypogonadism. But Primary hypogonadism has not yet been seen with MS although autoimmunity can be postulated to lead to primary testicular failure in these patients, but more studies and investigation will need to be done to establish this cause and effect relationship.
