- This statement is correct. Puberty is the stage in life when individuals develop the ability to reproduce, as their reproductive organs mature.

2. **Statement 2**: "All human beings of the same gender reach puberty at exactly the same age."
- This statement is incorrect. As discussed in the video, puberty does not occur at the same age for everyone of the same gender. There is a range of ages in which puberty can occur, typically between 10 to 14 years for girls and 12 to 16 years for boys, but this can vary widely among individuals.

3. **Statement 3**: "Puberty comes to an end once an individual attains sexual maturity."
- This statement is correct. Puberty is the process that leads to sexual maturity, and it concludes when an individual reaches this stage.

4. **Statement 4**: "The age at which puberty starts is different for all human beings."
- This statement is also correct. The onset of puberty can vary significantly from person to person due to genetic and environmental factors.

Based on this analysis, the statement that is not correct is **Statement 2**: "All human beings of the same gender reach puberty at exactly the same age."
