Objective: Gonadal and sexual disturbances are commonly encountered in patients with Cushing’s disease. Nevertheless, the prevalence of hypogonadism in male Cushing’s disease, the risk factors as well as the recovery time have been scarcely reported. Therefore, we aimed to explore the prevalence of hypogonadism at baseline and its determinants. In addition, the recovery time of hypogonadism and risk factors for unrecovered gonadal axis in male Cushing’s disease with biochemical remission were investigated.Methods: We reviewed medical records of males with Cushing’s disease managed between 2010 and 2020. Fifty-two male patients were enrolled according to the criteria. Each case attained biochemical remission after transsphenoidal surgery. Demographic details, clinical features, 24-hour UFC, hormonal profile [serum PRL, FSH, LH, TT, ACTH, cortisol, TT4/FT4, TT3/ FT3, TSH and IGF-1] were measured at baseline and during follow-up. The maximal tumor diameter on MRI was recorded at diagnosis.Results: Hypogonadotropic hypogonadism was observed in thirty-nine patients (75%) at diagnosis. Total testosterone was negatively correlated with ACTH and 24-hour UFC. Midnight serum ACTH level at diagnosis was significantly associated with hypogonadism after adjusting for confounding factors. Thirty-two (80%) patients achieved eugonadism within 12 months after the surgery, of which twenty-eight (87.5%) achieved eugonadism within 3 months. Seven patients were persistently hypogonadal during the follow-up (>1 year), mainly due to the hypopituitarism as a complication of the therapies such as surgery.Conclusion: Hypogonadotropic hypogonadism is frequent in male Cushing’s disease, but it is reversible in most cases within one-year follow-up after remission. |
