Exists a “ideal time” to have a family? Take it from these mums who know firsthand. Everyone you ask will offer a different answer, but accept it anyhow.

Late teens to late 20s are a woman’s reproductive prime. Fertility declines after 30. After mid-30s, deterioration accelerates. By 45, most women can’t conceive naturally.

At what age does having a family make sense? Science says

Eggs are few. Women age lose eggs. Older eggs may have defective chromosomes. As women age, uterine fibroids and endometriosis may affect fertility.

Biologically, women should have children before 35 and men before 40. 27% of physicians had this talk with 18-34-year-olds.

Postponing family planning should be more widely known.1 in 4 healthy 20s and 30s women will get pregnant in a single menstrual cycle.

By age 40, 1 in 10 women will conceive per cycle. Men’s fertility falls with age, but less predictably.

Age increases miscarriage and stillbirth risk. Older ladies have more multiples. Ovaries release more eggs per month as they age.

Parents debate when to have kids. Many women wait until their late 20s or 30s to have children, focusing on their careers.

According to the Independent, women who had birth in their 30s lived longer.
