The truth is couples better-designed studies out-of females age and you may pure virility were women created on the twentieth century-however, those that create will color a optimistic picture. You to definitely studies, wrote into the Obstetrics & Gynecology during the 2004 and you may went from the David Dunson (today from Duke College), checked the possibilities of maternity one of 770 European ladies. (The brand new fertility of women in their late 20s and you will very early 30s is almost the same-information within the and of in itself.)
