Which of the following structures is incorrectly matched to its function?

Options

A. Epididymis - maturation and storage of sperm
B. Fallopian tube - site of normal embryonic implantation
C. Prostate gland - adds alkaline substances to semen
D. Testes - Production of testosterone

Answer

To determine which structure is incorrectly matched to its function, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Option 1: Epididymis**
- **Function:** Maturation and storage of sperm.
- **Analysis:** The epididymis is indeed the accessory reproductive duct in males, where sperm mature and are stored. This match is correct.

2. **Option 2: Fallopian Tube**
- **Function:** Site of normal embryonic implantation.
- **Analysis:** The fallopian tube, also known as the oviduct, is primarily the site of fertilization, not implantation. After fertilization occurs in the fallopian tube, the fertilized egg (zygote) travels to the uterus, where implantation occurs. Therefore, this match is incorrect.

3. **Option 3: Prostate Gland**
- **Function:** Adds alkaline substances to semen.
- **Analysis:** The prostate gland is an accessory reproductive gland in males that secretes a fluid that is alkaline, which helps to neutralize the acidity of the vaginal tract and enhances sperm motility. This match is correct.

4. **Option 4: Testis**
- **Function:** Production of testosterone.
- **Analysis:** The testis is the primary reproductive organ in males and is responsible for the production of testosterone, which is essential for the development of male secondary sexual characteristics. This match is correct.

### Conclusion:
After analyzing all options, the structure that is incorrectly matched to its function is **Option 2: Fallopian Tube**.

### Final Answer:
**Option 2 is the incorrect match.**
