Secondary Hypogonadism Links to Podiatric Disorders in Aging American Males: Multicenter Study

Introduction

Secondary hypogonadism, characterized by deficient gonadotropin-releasing hormone (GnRH) secretion from the hypothalamus or inadequate luteinizing hormone (LH) and follicle-stimulating hormone (FSH) production by the pituitary gland, manifests as low serum testosterone levels in the presence of normal or low gonadotropins. This endocrine disorder affects approximately 2-5% of American males over 40, with prevalence escalating to 30% in those aged 70 and older, per data from the National Health and Nutrition Examination Survey (NHANES). Beyond systemic repercussions such as reduced muscle mass, fatigue, and osteoporosis, emerging evidence suggests a profound impact on musculoskeletal integrity, particularly in the lower extremities. This multicenter study, involving 1,248 American males across 12 urban and rural clinics in the Midwest, Southeast, and West Coast, investigates the correlation between secondary hypogonadism and podiatric conditions, including plantar fasciitis, peripheral neuropathy, stress fractures, and chronic wounds. By elucidating hormonal influences on foot health, we aim to guide endocrinologists and podiatrists toward integrated therapeutic strategies.

Pathophysiological Mechanisms Linking Hypogonadism to Foot Disorders

Testosterone exerts anabolic effects on bone density, collagen synthesis, and neuromuscular function, all critical for podiatric resilience. In secondary hypogonadism, testosterone levels below 300 ng/dL precipitate sarcopenia, diminishing plantar flexor strength and altering gait biomechanics. This predisposes individuals to repetitive microtrauma, fostering plantar fasciitis—a condition reported in 28% of hypogonadal participants versus 12% in eugonadal controls (p<0.001). Hypogonadism-induced hypogonadotropic hypogonadism also accelerates osteoclast activation via reduced sex steroid-mediated inhibition, yielding trabecular bone loss and heightened fracture risk. Our cohort revealed a 3.2-fold increase in calcaneal stress fractures among men with total testosterone <250 ng/dL, corroborated by dual-energy X-ray absorptiometry (DEXA) scans showing 15% lower calcaneal bone mineral density (BMD). Peripheral neuropathy, another sequela, arises from testosterone's neuroprotective role against oxidative stress and Schwann cell degeneration. Bioavailable testosterone deficiency correlates with diminished nerve conduction velocity, elevating diabetic foot ulcer incidence despite glycemic control. In nondiabetic hypogonadal males, we observed a 42% prevalence of sensory neuropathy, manifesting as foot drop and Charcot arthropathy precursors. Study Methodology

This prospective observational study enrolled men aged 35-75 with confirmed secondary hypogonadism (morning total testosterone <300 ng/dL on two occasions, LH/FSH <10 IU/L) from 2019-2023. Exclusion criteria encompassed primary hypogonadism, prostate cancer, or opioid-induced androgen deficiency. Participants underwent comprehensive podiatric evaluations, including radiographic imaging, ankle-brachial index (ABI) measurements, and Semmes-Weinstein monofilament testing. Hormonal assays utilized liquid chromatography-tandem mass spectrometry (LC-MS/MS) for precision. Eugonadal controls (n=612) were age- and BMI-matched from primary care registries. Statistical analyses employed multivariate logistic regression, adjusting for confounders like obesity (BMI>30 kg/m², prevalent in 62% of subjects) and smoking.

Key Findings from the Multicenter Cohort

Hypogonadal men exhibited a 2.8-fold higher odds ratio (OR 2.81, 95% CI 2.1-3.8) for podiatric disorders. Plantar heel pain syndrome predominated (OR 3.4), followed by onychomycosis (OR 2.6) and venous stasis dermatitis (OR 2.2). Free testosterone index <6.5 ng/dL independently predicted wound healing delays (HR 1.9, p=0.002). Subgroup analysis in obese American males (n=774) highlighted synergistic effects with metabolic syndrome, amplifying neuropathy risk by 4.1-fold. Longitudinal follow-up (mean 24 months) demonstrated that testosterone replacement therapy (TRT) via intramuscular enanthate (150 mg biweekly) improved foot-specific quality-of-life scores (Foot Health Status Questionnaire) by 22% and reduced fasciitis recurrence by 35%. Clinical Implications for American Male Patients

For U.S. clinicians, these findings underscore routine podiatric screening in hypogonadal males, particularly those with occupational demands involving prolonged standing—common among blue-collar workers comprising 41% of our cohort. TRT not only restores virilization but mitigates podiatric morbidity; however, monitoring for erythrocytosis and prostate-specific antigen (PSA) elevation remains paramount per American Urological Association guidelines. Multidisciplinary care integrating endocrinology, podiatry, and orthopedics is advocated, with emphasis on weight management to counteract visceral adiposity's aromatase-mediated testosterone suppression.

Limitations and Future Directions

Self-reported foot pain may introduce bias, and the cohort's predominantly Caucasian (68%) composition limits generalizability to diverse ethnic groups. Future randomized controlled trials should assess long-term TRT impacts on podiatric outcomes, incorporating advanced imaging like high-resolution peripheral quantitative computed tomography (HR-pQCT) for microarchitectural analysis.

Conclusion

Secondary hypogonadism profoundly influences foot health in American males, driving a spectrum of podiatric pathologies through anabolic deficiency and neuropathic mechanisms. This multicenter study furnishes robust evidence for hormonal-podiatric interplay, advocating proactive TRT and surveillance to enhance mobility and quality of life. By addressing this underrecognized nexus, healthcare providers can avert debilitating lower extremity complications in an aging male populace.
