According to Medical News Today, the best age for childbearing is between 20 and 35 years of age. According to She Knows, the ideal range is between 25 and 35 due to the fact that most individuals have completed their education and are in the workforce by age 25.
Although it is possible, childbearing after age 35 is not ideal due to the fact that age-related fertility problems increase after this age. For men, semen counts gradually deteriorate over the years. Medical News Today notes that children fathered by older men have an increased risk for schizophrenia and genetic disorders.
