Female age is important when considering probability for getting pregnant. Increased infertility rates with aging are well documented and apparent in our society. The real issue is egg quantity and quality. Which translates into embryo quality after fertilization. As women wait longer to have children. More couples have fertility problems due to declining egg quality. And other issues that are more common in older women. Many couples end up needing advanced treatments such as IVF to overcome this age related decline. Many fertility doctors recommend that women over about 38 that are infertile should have aggressive fertility treatments and proceed to IVF sooner. Before fertility potential is lost. IUI success rates decline with female age. So older women often prefer to move on to IVF after a few IUIs have failed. All clinics have an upper age limit after which they will not do IVF with the woman’s own eggs. Most IVF centers will attempt IVF using the female partner’s eggs until about age 43-45.
