Hi, I’m Dr. Ingrid Rodi and I am a specialist in reproductive endocrinology and infertility with RodiMD.com. Today I am here on behalf of About.com to talk to you about How Age Impacts Infertility.Age is primarily a factor for women’s fertility. Men’s fertility also decreases with age, especially after 40, but not to the same degree. Age only became a significant issue for women in the last quarter of the 20th Century. Until that time, women married young and our primary occupation was to have and raise children. That all changed when more of us started going to college and joining the work force. We devote longer periods of time to developing our careers. As a result, we marry and have children at an older age.Women are the most fertile in our mid 20s. Some women start having trouble getting pregnant in their late 20s. As women enter their 30s and 40s, an increasing percentage will have difficulty getting pregnant. By the time a woman is 47 years of age, her chance of having a healthy baby with her own eggs is almost zero.There are a number of reasons why women have difficulty having children as we age. The first is that the most fertile eggs are probably ovulated early in the woman’s life. It may also be that the longer they are in a woman’s body, the more they have been exposed to the elements. An extreme example of this is a woman who has been exposed to radiation or chemotherapy. Some women have more medical problems as they age, which can reduce fertility. An example of this is diabetes. Most women gain weight with age. A BMI over 25 is associated with a decrease in fertility. In addition to an increase in infertility with age, women experience increasing rates of miscarriage as well. This combines to further lower the chance of delivering a healthy baby.Thank you for watching. To learn more, visit us online at About.com.
