Answer

To determine how many of the given statements about the human reproductive system are incorrect, we will analyze each statement one by one.

### Step 1: Analyze Statement (A)
**Statement (A):** The uterus is an inverted pear-shaped organ.

- The uterus is indeed described as an inverted pear-shaped organ. It is a muscular organ located in females where the fetus develops during pregnancy. Therefore, this statement is **correct**.

### Step 2: Analyze Statement (B)
**Statement (B):** Each testis possesses 150 testicular tubules.

- Each testis contains numerous structures called testicular lobules. Each testis typically has about 250 lobules, and within each lobule, there are seminiferous tubules where sperm is produced. Since the statement claims there are only 150 testicular tubules, this statement is **incorrect**.

### Step 3: Analyze Statement (C)
**Statement (C):** Mammary tubules open into the mammary ducts.

- Mammary glands are responsible for milk production and consist of lobes and lobules. The mammary tubules do indeed open into the mammary ducts, which transport milk to the nipple. Therefore, this statement is **correct**.

### Conclusion
After analyzing all three statements:
- Statement (A) is correct.
- Statement (B) is incorrect.
- Statement (C) is correct.

Thus, only **one statement** is incorrect.

### Final Answer:
**Only 1 statement is incorrect.**
