At what stage of life does the ability to reproduce typically begin?

The ability to reproduce typically begins in puberty, which is the developmental stage that signifies the transition from childhood to adulthood. During puberty, individuals experience various physiological changes driven by hormonal shifts, leading to the development of secondary sexual characteristics and the maturation of reproductive organs.

For females, this includes the onset of menstruation, known as menarche, marking the beginning of reproductive capability. For males, puberty results in the production of sperm and the development of features such as increased muscle mass and body hair. This stage sets the foundation for future reproductive health and behavior.

Menopause occurs much later in life and signifies the end of a female's reproductive years, while adolescence encompasses a broader age range that includes both pre-puberty and post-puberty stages. Infancy refers to the early stage of life, well before the onset of reproductive abilities. Thus, puberty is the accurate stage of life when the capacity for reproduction begins.
