The epididymis is essential for sperm maturation, motility acquisition, and storage. While spermatogenesis occurs within the testes, spermatozoa leaving the testicular environment are immature and incapable of fertilization.
During transit through the epididymis, sperm undergo biochemical and structural modifications that enable functional competence. Inflammation, obstruction, or congenital abnormalities affecting this structure may significantly impair fertility.
Andrological evaluation includes assessment erotic of epididymal function, particularly in cases of obstructive azoospermia or post-infectious infertility.
