Question

Which of the following is a set of male accessory ducts?
(a)Rete testis, vasa efferentia, tubuli recti
(b)Rete testis, vasa efferentia, epididymis and vas deferens
(c)Epididymis, ejaculatory duct, urethra
(d)Seminiferous tubules, vasa efferentia, epididymis, and vas deferens

Answer 1

Hint: Male accessory glands produce the products which mix with the sperm to protect and preserve them. The protein content can be increased by some insecticides and has an intended effect of increasing the number of offspring they can produce. The glands secrete a fluid that helps in the nourishment of the sperms.

Complete answer:
Rete testis, vasa efferentia, epididymis, and vas deferens are the set of male accessory ducts. Vasa efferentia is located inside the testis and hence is intratesticular. It arises from the rete testis which conducts spermatozoa to the epididymis and connects the seminiferous tubules to the ductus differences. It constitutes ciliated cuboidal epithelial cells around it and contains microvilli. The cilia help in the movement of spermatozoa along the tube which are non-motile until they reach the epididymis. The microvilli help in absorbing excess materials which includes potassium and protein from the seminal fluid. These ducts help in the storage of spermatozoa and the transportation of them outside the urethra during ejaculation. They contribute towards the seminal plasma to semen and account for 60% of the seminal plasma by adding alkaline pH, mucous, fructose, coagulating, and the local acting enzymes.

Additional Information: The male reproductive system and specialized for producing and nourishing sperm and the protective fluid which is semen. They produce and secrete male sex hormones and discharge sperm within the female reproductive tract. The penis helps with the intercourse and urination and the urine and semen leave the penis through the urethra. The epididymis connects the vas defence and the back of the testis which functions to store and carry the sperms. It is called a collection of tubes in the testis which are seminiferous tubules where the process of spermatogenesis takes place.

So, the correct answer is 'Rete testis, vasa efferentia, epididymis and vas deferens'.

Note: The average size of the penis in males is less than 6 inches long and 5.6 inches is average according to the researchers which reported a huge variation in size from their survey. a healthy man releases up to 1.2 million sperm cells during ejaculation in a single moment.
