Question

Read the sources given and answer any four from the questions given below:

The male reproductive system consists of certain accessory ducts such as rete testis, vasa efferentia, epididymis and vas deferens. Rete testis are the network of tubules which are located on the inner side of the testis. From here vasa efferentia emerge which are the small ducts that carry sperms to the epididymis. In epididymis, the sperms get concentrated and pass to vas deferens. Vas deferens opens into the common urethra. Male accessory glands include: prostate glands, seminal vesicle and bulbourethral glands. Semen is the fluid containing spermatozoа and secretions of accessory glands. Seminal vesicles add secretion containing spermatozoa activating substances like fructose, citrate and prostaglandins, etc. Prostate glands present at the neck of the urinary bladder secrete the alkaline fluid which is essential to neutralise the acidic secretions present in vagina. Bulbourethral glands also known as Cowper's glands located just above the prostate gland, add clear mucous and glycoproteins which act as lubricant.
