BACKGROUND AND PURPOSE: Parkinson disease (PD) presents relevant sex-related differences in epidemiology, pathophysiology, and clinical features, with males being more vulnerable to the disease. Sex hormones might have a role, as the experimental models suggest; however, human-based evidence is scarce. Here, we integrated multimodal biomarkers to investigate the relationships between circulating sex hormones and clinical-pathological features in male PD patients. METHODS: A cohort of 63 male PD patients underwent comprehensive clinical evaluation of motor and nonmotor disturbances; measurement of estradiol, testosterone, follicle-stimulating hormone (FSH), and luteinizing hormone (LH) blood levels; and cerebrospinal fluid (CSF) assay of total α-synuclein, amyloid-ß-42, amyloid-ß-40, total tau, and phosphorylated-181 tau levels. A subgroup of 47 PD patients underwent brain volumetry by 3-T magnetic resonance imaging for further correlations. A control group of 56 age-matched individuals was enrolled for comparative analyses. RESULTS: Male PD patients had higher estradiol and testosterone levels than controls. Estradiol had independent inverse associations with Movement Disorder Society-Unified Parkinson's Disease Rating Scale Part 3 score and disease duration; it was also lower in nonfluctuating patients. Testosterone had inverse independent correlations with CSF α-synuclein and right globus pallidus volume. FSH and LH had age-dependent correlations with cognitive impairment and CSF amyloid-ß-42/amyloid-ß-40 ratio. CONCLUSIONS: The study suggested that sex hormones could differentially contribute to clinical-pathological features of PD in male patients. Whereas estradiol might have a protective role in motor impairment, testosterone might be involved in male vulnerability to PD neuropathology. Gonadotropins instead might mediate age-dependent phenomena of amyloidopathy and cognitive decline.
