Pathophysiology of Sperm Disorders
Spermatogenesis occurs continuously. Each germ cell requires about 72 to 74 days to mature fully. Spermatogenesis is most efficient at 34°C. Within the seminiferous tubules, Sertoli cells regulate maturation, and Leydig cells produce the necessarytestosterone. Fructose is normally produced in the seminal vesicles and secreted through the ejaculatory ducts. Sperm disorders may result in An inadequate quantity of sperm—too few (oligozoospermia) or none (azoospermia) Defects in sperm quality, such as abnormal motility or structure
