Humans, biologically speaking, are capable of reproducing throughout their reproductive years. In general, women are born with a finite number of eggs, and men produce sperm continuously.

For females, the reproductive age typically spans from the onset of menstruation (usually around age 12-14) until menopause, which commonly occurs between the ages of 45 and 55. During this time, women release eggs monthly during their menstrual cycles and can potentially conceive.On the male side, men can produce sperm throughout most of their lives, although the quantity and quality of sperm may decline with age.It’s important to note that individual factors such as health, lifestyle, and environmental factors can influence fertility. While the biological capability for reproduction may exist, external factors can impact the actual ability to conceive and carry a pregnancy to term.Additionally, advancements in reproductive medicine, such as in vitro fertilization (IVF) and other assisted reproductive technologies, have expanded the possibilities for conception, allowing individuals to overcome certain fertility challenges.In summary, humans have the potential for reproduction from adolescence until menopause in females and throughout much of their lives in males, but various factors can influence the actual ability to conceive.
