Diagram of Male Reproductive System Online Biology Tutors Tutorpace Human male reproductive system consists of a pair of testes, vasa efferentia, a pair of epididymis, a pair of vasa differentia, a pair of seminal vesicles, urino genital tract, prostate gland, a pair of Cowpers gland and penis. Testes: They are the male gonads responsible for the production of sperm and testosterone. Each testis is found inside a muscular bag called scrotum to maintain the temperature 1 to 3 degrees lower than the normal human body temperature s. The inside of the testes is divided into small compartments called lobules. Each lobule contains a section of seminiferous tubule lined with epithelial cells. The sperms are formed by spermatogenesis. Epididymis: Each testes opens into a long coiled tubule of 4-6 m length through12-14 fine tubules called vasa efferentia. The long tubule is called epididymis. It stores and nourishes the sperms. Vasa Differentia: Epididymis opens into a thick muscular tube called vas deferens which is 30-35 cm long.They receives the duct from seminal vesicle to form the ejaculatory duct. They join the urethra to produce urino genital duct which receives the secretion of prostate and Cowpers gland and then enter into the penis. Seminal vesicle: A pair of lobulated glands that produce 60-70% of semen plasma for nourishing and stimulating sperms. Prostate gland: Single large pyramidal gland which contains chemicals essential for motility of sperms. Cowpers gland: A pair of small glands which secrete a fluid which lubricates urino genital duct and neutralizes its acidity. Penis: Male copulatory organ
