Which is the correct pathway of sperms.
(i) Epididymis (ii) Seminiferous tubules
(iii) Vas - efferentia (iv) Rete-testis

Answer

To determine the correct pathway of sperm, we need to follow the sequence in which sperm travels through the male reproductive system. Here’s the step-by-step breakdown:

1. **Seminiferous Tubules**: The pathway begins in the seminiferous tubules, which are located within the testes. This is where sperm production occurs through a process called spermatogenesis.

2. **Rete Testis**: After the sperm are produced in the seminiferous tubules, they move into the rete testis. The rete testis is a network of small tubes that collects sperm from the seminiferous tubules.

3. **Vas Efferentia**: From the rete testis, sperm then travel through the vas efferentia (also known as efferent ductules). These are small ducts that transport sperm from the rete testis to the epididymis.

4. **Epididymis**: The sperm then enter the epididymis, where they mature and are stored until ejaculation. The epididymis consists of a coiled tube that allows for the maturation process.

5. **Vas Deferens**: Finally, from the epididymis, sperm are transported through the vas deferens during ejaculation.

Thus, the correct pathway of sperm is: **Seminiferous Tubules → Rete Testis → Vas Efferentia → Epididymis**.

### Summary of the Correct Pathway:
1. Seminiferous Tubules
2. Rete Testis
3. Vas Efferentia
4. Epididymis
