Answer

To solve the question regarding reproductive health and identify the incorrect statement, we will analyze each statement provided in the question step by step.

### Step 1: Analyze the First Statement
**Statement:** Nearly 45 to 50 million MTPS (Medical Termination of Pregnancy) are performed in a year all over the world.

- **Analysis:** This statement is true. It is estimated that around 45 to 50 million abortions occur annually worldwide, which is approximately one-fifth of all pregnancies. Therefore, this statement is correct.

### Step 2: Analyze the Second Statement
**Statement:** STDs are also called venereal diseases (VD).

- **Analysis:** This statement is also true. Sexually Transmitted Diseases (STDs) are indeed referred to as venereal diseases. The term "venereal" is derived from Venus, the Roman goddess of love, and these diseases can be transmitted through sexual contact as well as other means such as needles and blood transfusions. Thus, this statement is correct.

### Step 3: Analyze the Third Statement
**Statement:** The intracytoplasmic sperm injection (ICSI) is a technique involved in in vitro fertilization (IVF).

- **Analysis:** This statement is true. ICSI is a specialized form of IVF where a single sperm is injected directly into an egg to facilitate fertilization. The resulting zygote is then cultured and transferred to the uterus. Therefore, this statement is correct.

### Step 4: Analyze the Fourth Statement
**Statement:** The inability to conceive or produce children even after nine months of unprotected sex is called sterility.

- **Analysis:** This statement is incorrect. The medical definition of sterility refers to the inability to conceive after one year of unprotected sexual intercourse, not nine months. Therefore, this statement is incorrect.

### Conclusion
After analyzing all the statements, the incorrect statement regarding reproductive health is the fourth statement.

**Answer:** The incorrect statement is option 4: "The inability to conceive or produce children even after nine months of unprotected sex is called sterility."
