Advances in the diagnosis and treatment of male infertility - an overview of current methods.

Male infertility is a multifactorial condition influenced by hormonal, anatomical, genetic, and lifestyle factors. Although the male factor contributes to up to 40% of infertility cases, the exact etiology often remains unknown (so-called idiopathic infertility). Current diagnostic approaches include detailed clinical evaluation, semen analysis, hormonal assessment, genetic testing, and imaging techniques. Significant progress has been achieved in sperm DNA fragmentation testing and oxidative stress evaluation, offering a broader insight into sperm quality. Treatment strategies vary depending on the underlying cause, ranging from pharmacological therapy and surgical interventions to assisted reproductive technologies. Rapid advances in regenerative medicine and gene therapy show promise for novel therapeutic options. A healthy lifestyle and risk factor management are integral to both prevention and treatment.
