Women can have children when they have menstrual periods at around 12-13 years of age, but the optimal age for women to have children is around 23-30 years of age. Generally, a woman enters puberty around the age of 12, and puberty develops around the age of 12-13 when menstruation occurs. Although she has the ability to conceive normally at this time, her body is not fully developed, and this is not the optimal age for childbearing. The optimal age for women to have children is generally between 23-30 years old. At the age of 23-30, a woman’s body is fully developed and her eggs are of the highest quality, which makes childbirth less risky, better for the growth and development of the fetus, and less likely to result in a preterm baby or a deformed baby. Even if a woman can give birth at a younger age, it is difficult for her to meet the standards of eugenics, so it is not recommended to give birth at the youngest age.
