Erectile Dysfunction and Hormonal Factors in Male Health
Summary
Erectile dysfunction is a prevalent condition characterised by the persistent inability to achieve or maintain an erection sufficient for satisfactory sexual performance. Its aetiology is multifactorial, encompassing vascular, neurological, psychological and endocrine components. Hormonal factors, particularly androgens such as testosterone, play a central role in modulating libido, penile vascular function and smooth muscle relaxation. Declining serum testosterone levels, often observed with advancing age, obesity or comorbidities, are implicated in the onset and progression of erectile symptoms. Moreover, alterations in sex hormone-binding globulin influence the bioavailability of free testosterone, further affecting erectile physiology. Emerging evidence highlights a bidirectional relationship between erectile dysfunction and general health: hormonal deficiency can precipitate sexual dysfunction, while erectile symptoms may serve as an early indicator of cardiovascular and metabolic disorders. Therapeutic strategies encompass lifestyle modification, pharmacological vasodilators and, in selected cases of true hypogonadism, hormone replacement. Understanding the interplay between endocrine regulation and penile function is essential for comprehensive management and for mitigating associated systemic risks.
