Abstract

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‐β‐42, amyloid‐β‐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‐β‐42/amyloid‐β‐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.

  • Dysregulation of microglial functions is associated with several health concerns that often show sex prevalences, including Alzheimer's disease (more prevalent among females), Parkinson's disease (more male-prevalent), and various other neurodevelopmental, neuropsychiatric and neurodegenerative disorders.

    “Dysregulation of microglial functions is associated with several health concerns that often show sex prevalences, not only affecting Alzheimer’s disease, which shows more prevalence among females, and Parkinson’s disease, more male-prevalent, but also including various other neurodevelopmental, neuropsychiatric and neurodegenerative disorders [38–43].”

    From Sex chromosomes and sex hormones differently shape microglial properties during normal physiological conditions in the adult mouse hippocampus (2025) · cites this paper as [41]

    The Introduction states that Parkinson disease is more prevalent in males, supporting the sex-prevalence portion relevant to this paper. The passages on neuroinflammation do not establish the sentence’s association between microglial dysfunction and Parkinson disease; the paper’s focus is sex hormones and PD biomarkers.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
