How does age factor into fertility?

As women age, their fertility declines due to decreased quantity and quality of eggs. With age, fertile cervical mucus also tends to decrease and cycles become shorter. Declining fertility is inevitable even for very healthy women, and this natural process begins in our late twenties. However, if you're in your late thirties or early forties, there are many options available to you; we recommend consulting with your doctor about doing a fertility evaluation and doing intrauterine inseminations (IUI).
