"As far as health is concerned, 24 to 30 is the best age to get pregnant because a woman is at the peak of fertility. Too early or too late carries risks of complications," says Dr Joe Wanyoike Gichuhi, a senior lecturer in the Department of Obstetrics and Gynaecology at the University of Nairobi. As age increases, he says, so does the risk of other problems that may affect fertility such as uterine fibroids, adenomyosis and endometriosis.
