Give an account of the secondary sex organs of human male reproductive system

Explanation

The secondary sex organs of human male reproductive system
(i) Accessory duct system It includes rete testis, vasa enerentia, epididymis and vas deferens.
(a) The intratesticular duct system starts with tubuli recti and connects the seminiferous tubules to the highly anastomosing, cuboidal epithelium-lined channels called rete testis.
(b) from rete testis, 10-25 fine tubules called vasa efferentia which arise, leave the testes and open fnto epididymis and also carry sperms outside the body.
(c) Epididymis is a long tube which is greatly coiled and tightly packed to form an elongated flattened body.
(d) The vas deferens ascends to the abdomen and loops over urinary bladder. It receives a duct from seminal vesicle to form ejaculatory duct. It passes through the prostate gland and opens into the urethra that further passes through the penis to its external opening called urethral meatus.
(ii) Accessory glands The accessory glands or the
secondary glands include prostate gland, two seminal vesicles and Cowper.s gland or bulbourethral glands.
(a) Prostate glands These glands secrete mucus and a slightly alkaline fluid. The secretion contains lipids, enzymes, citric acid, etc., which is released during ejaculation and helps to neutralise the acidic medium of vagina, making sperms more active to swim.
(b) Seminal vesicles They secrete mucus and a watery alkaline fluid that contain nutrients including the
