Age and Fertility

Many, many women elect to have children at later ages. There are varied reasons for doing so, from fulfilling career obligations to not finding the right partner until later in life to simply not feeling ready. Fertility does decline with age, noticeably after age 38 and markedly after age 42. But fortunately, the medical technology we use at Arizona Associates for Reproductive Health (AZARH) provides a number of options to women over the age of 35 who wish to get pregnant. We are honored that you are considering Arizona Associate for Reproductive Health to help you build your family. Our Arizona fertility specialists welcome you to schedule a consultation at our Phoenix, area fertility clinics located in Scottsdale and Gilbert or call 480-946-9900 to start your journey!

Why Does Fertility Decline with Age?

Normal, age-related changes occur in the ovaries as women get older. Every woman is born with all of the eggs she will ever have. At birth, a typical female has approximately one million eggs in her ovaries. By puberty, there are only about 300,000. Of these remaining eggs, only about 300 will actually be ovulated throughout her life, with the rest lost through a normal degenerative process. Along with a decline in the total number of eggs, as a woman ages, there is a decrease in both the egg quality and egg quantity.

Fertility after 30

Quality of Eggs for Women after 30

As a woman ages so do her eggs. And with time more and more of a woman’s eggs have either too few or too many chromosomes. If one of these eggs is fertilized, the resulting embryo will also have too few or too many chromosomes. In these cases, most of these embryos result in miscarriage.

Quantity of Eggs for Women after 30

As years pass, the number of eggs a woman has decreases. Our Arizona fertility doctors refer to this as a “loss of ovarian reserve,” and makes it more difficult to conceive a baby. Compounding the difficulty, it is more difficult for the remaining eggs to mature and ovulate.

Pregnancy Rates by Age

A woman’s best chance of conceiving is in her 20s. By her 30s there is a normal and gradual decline in fertility, particularly after age 38 and markedly after 40. While a typical healthy 30-year-old woman has a 20% chance of getting pregnant each month, a 40-year-old woman’s chance drops to 5% per cycle. By the mid-40s, most women are unable to have a successful pregnancy. The fertility experts at Arizona Associates for Reproductive Health recommend that if you’re over 35 and haven’t conceived within 6 months of trying that you consult a specialist.

Fertility by Age

There are several options that can help women with age-related fertility problems, including the following:
