Testicular dysfunction refers to the impaired ability of the testes to produce sperm or hormones, particularly testosterone. This condition can lead to issues such as infertility, reduced libido, and other hormonal imbalances. Various factors, including genetic disorders, infections, and hormonal imbalances, can contribute to testicular dysfunction. Diagnosis typically involves a physical examination, hormone level tests, and semen analysis. Treatment options may include hormone replacement therapy, medications, or assisted reproductive technologies, depending on the underlying cause. Early detection and intervention can help manage symptoms and improve overall reproductive health.
