Diagnosis and Treatment of Primary, Secondary, and Functional Male Hypogonadism: A Narrative Review

Abstract

Male hypogonadism refers to a condition characterized by reduced testosterone production or impaired sperm production. Traditionally, it was classified into two categories: congenital and acquired hypogonadism. However, with the emergence of the concept of functional hypogonadism, which develops as a result of chronic diseases, medications, or aging, male hypogonadism is now considered under three subtypes. The clinical manifestations and treatment strategies vary depending on the underlying cause of hypogonadism. Additionally, the desire for fertility significantly influences the treatment protocol. This systematic review examines the diagnostic and therapeutic approaches to primary, secondary, and functional male hypogonadism.
