Rete testis opens to

Options

A. urethra
B. vasa efferentia
C. bidder's canal
D. cauda epididymis

Answer

**Step-by-Step Solution:**

1. **Understanding the Structure of the Testes:**
- The testes are divided into lobes, typically numbering between 250 to 300. Each lobe contains seminiferous tubules where sperm production occurs.

2. **Identifying the Seminiferous Tubules:**
- Inside each lobe, there are 2 to 3 seminiferous tubules. These tubules are responsible for the production of sperm.

3. **Continuity of the Seminiferous Tubules:**
- The seminiferous tubules converge into a network of tubules known as the tubuli recti (or straight tubules), which then lead into the rete testis.

4. **Understanding the Rete Testis:**
- The rete testis is a network of tubules located in the hilum of the testes. It collects sperm from the seminiferous tubules.

5. **Connection to the Vas Efferentia:**
- The rete testis opens into 13 to 14 small ducts called the vas efferentia. These ducts transport sperm from the rete testis to the epididymis.

6. **Final Connection to the Epididymis:**
- The vas efferentia then connect to the epididymis, where sperm mature and are stored.

7. **Conclusion:**
- Therefore, the rete testis opens to the vas efferentia, which is the correct answer.

**Answer: The rete testis opens to the vas efferentia.**
