Intra testicular genital duct system includes:-

Options

A. Tubuli recti, rete testis and Vasa efferentia
B. Tubuli recti, vas deferens and ejaculatory duct
C. Urethra, epididymis and Tubuli recti
D. Seminal vesicle, ejaculatory duct and ampulla

Answer

**Step-by-Step Solution:**

1. **Understand the Question**: The question asks about the components of the intra testicular genital duct system. This system refers to the ducts located within the testes.

2. **Identify the Types of Duct Systems**: There are two types of genital duct systems:
- **Intratesticular Duct System**: This includes structures located inside the testes.
- **Extratesticular Duct System**: This includes structures located outside the testes.

3. **List the Components of the Intratesticular Duct System**:
- The main components of the intratesticular duct system are:
- **Seminiferous Tubules**: These are the sites of sperm production.
- **Rete Testis**: This is a network of tubules that collects sperm from the seminiferous tubules.
- **Vasa Afferentia**: These are small ducts that transport sperm from the rete testis to the epididymis.

4. **Analyze the Options Given**:
- **Option 1**: Tubular erectile, rete testis, and vasa afferentia. (This option includes components of the intratesticular duct system.)
- **Option 2**: Tubular erectile, vas deferens, and ejaculatory duct. (Vas deferens and ejaculatory duct are extratesticular.)
- **Option 3**: Urethra, epididymis, tubular erectile. (Urethra is extratesticular.)
- **Option 4**: Seminal vesicles, ejaculatory duct, and ampulla. (All are extratesticular.)

5. **Select the Correct Answer**: Based on the analysis, **Option 1** (tubular erectile, rete testis, and vasa afferentia) is the only option that correctly lists components of the intratesticular genital duct system.

**Final Answer**: The intra testicular genital duct system includes: **Tubular erectile, rete testis, and vasa afferentia** (Option 1).
