A very important fertility factor is reproductive age.

First thing that I want to talk about is a female's age and how that impacts our reproduction. Women are born with almost all of their eggs, and we're going to use up our eggs during our lifetime. And once our eggs are gone, we're going to go through menopause.

The average age for menopause in the United States is 51, but we rarely see a pregnancy with a woman using her own eggs past the age of 44. And that's because as we reach our mid 40s, we have most of our eggs being genetically abnormal. So, two really important factors for female age are the egg number, which declines over time. But also, the quality of the eggs. These factors combined can make it difficult to have a pregnancy as we age.

Another really important thing is male age. And this really hasn't been highlighted until recently. Some recent studies show that male age is also very important. Although, a man will continue to make sperm, and be able to have children late into his life, which is different than a woman, we are now finding that male age is also important in the health of a pregnancy. And actually may be related to increased risks of autism or schizophrenia. Both of these things are very important. And one of the things that we would talk about during an initial evaluation.
