Even if a person never has childrenthat person can still reproduce how?

A person can reproduce through assisted reproductive technologies, such as in vitro fertilization (IVF) or artificial insemination, even if they never have biological children themselves. Additionally, they can contribute to reproduction by donating sperm or eggs, which can be used by others to conceive. Furthermore, they may also choose to adopt children, thereby playing a critical role in the upbringing of future generations without biological reproduction.
