Question

Which of the following depicts the correct pathway of transport of sperms?
A) Rete testis - efferent ductules - epididymis - vas deferens
B) Rete testis - epididymis - efferent ductules - vas deferens
C) Rete testis - vas deferens - efferent ductules - epididymis
D) Efferent ductules - rete testis - vas deferens - epididymis.

Answer 1

Hint: In male reproductive system, the internal organs are called accessory organs. The accessory ducts in male includes vas deferens, rete testis, epididymis and vasa efferentia. They help in storage and transportation of sperm.

Complete answer:
The male reproductive cell is called sperm. They are produced in the seminiferous tubules in testicles. The sperm from seminiferous tubules of testis moves into vasa efferentia through rete testis. Epididymis lies along the surface of the testis. Vasa efferentia opens into epididymis and then leads to vas deferens . Vas deferens then enters the abdominopelvic cavity and a ejaculatory duct is formed from the seminal vesicle which opens into urethra.
Hence the sperms are transported to epididymis from rete testis through efferent ductules . When there is smooth muscle contraction, the matured sperms are transported into vas deferens .

Therefore the correct answer is (A) Rete testis - efferent ductules - epididymis - vas deferens.

Note:Approximately it takes around 40 to 50 days for sperms to develop in the scrotum of the testis. The sperms are immobile until they reach epididymis. They reach epididymis with the help of ciliated cuboidal epithelial cells in the efferent duct. Sperms are matured and stored in epididymis. It takes 14 days for sperms to mature in epididymis .
