B. The reproductive events occur after puberty.
C. The formation of sperms continues even in old men.
D. Insemination is not considered a reproductive event in humans.

Answer

To identify the incorrect statement in relation to human reproduction, we will analyze each of the provided statements step by step:

### Step-by-Step Solution:

1. **Statement Analysis**:
- **Statement 1**: "There are remarkable differences between the reproductive events in the male and in the female."
- **Analysis**: This statement is true. Males and females have different reproductive processes. For example, males produce sperm throughout their lives, while females have a finite number of eggs and typically stop ovulating around age 50 (menopause).

2. **Statement 2**: "The reproductive events occur after puberty."
- **Analysis**: This statement is also true. Puberty is the stage when individuals develop secondary sexual characteristics and become capable of reproduction. In both males and females, reproductive events begin after reaching puberty.

3. **Statement 3**: "The formation of sperms continues even in old men."
- **Analysis**: This statement is true as well. Unlike females, who have a limited number of eggs, males can produce sperm throughout their lives, although the quantity and quality may decline with age.

4. **Statement 4**: "Insemination is not considered a reproductive event in humans."
- **Analysis**: This statement is incorrect. Insemination, which is the introduction of sperm into the female reproductive tract, is indeed considered a crucial reproductive event in humans as it is necessary for fertilization to occur.

### Conclusion:
The incorrect statement in relation to human reproduction is **Statement 4**: "Insemination is not considered a reproductive event in humans."
