There is no definite answer to the question of whether ovulation occurs at the age of 12, because each child's physical health is different. For 12-year-olds, they are in the early stages of adolescence and their bodies are undergoing tremendous changes. Some studies have shown that adolescent children may enter the ovulation period around the age of 12, but this is only based on statistical data and theoretical inference and cannot be regarded as an absolute fact.

In addition, in adolescent girls, their ovaries may undergo some physiological changes, such as ovarian development and maturation, which may increase their ovulation period. However, these changes may also vary due to individual differences, so whether a 12-year-old child is ovulating needs to be judged on a case-by-case basis.

Children as young as 12 are in the early stages of adolescence, and their physical health may vary based on individual differences. Therefore, we should not judge whether they are ovulating based on statistical data and theoretical inference. If you or someone around you has this problem, it is recommended to consult a doctor or professional health care institution to obtain more accurate diagnosis and treatment suggestions.
