lisääntymisikäisenä

lisääntymisikäisenä is an Estonian term that translates to "of reproductive age" in English. It refers to the period in a person's life when they are biologically capable of reproduction. This age range typically begins with the onset of puberty, when reproductive organs mature and hormonal cycles commence, and ends with menopause in females or a general decline in fertility in males.

The specific age at which individuals enter and exit the reproductive age can vary based on genetic factors, environmental influences, and overall health. In many societies, the legal age of consent for sexual activity and marriage, which are often associated with reproduction, may differ from the biological reproductive age. Understanding the concept of reproductive age is important in various contexts, including demographics, public health, and discussions about family planning and reproductive rights. It is a biological classification rather than a social or legal one, though societal norms and laws may interact with this biological reality.
