Under- Mature AND Over-Mature

Elizabeth • My name is Liz and my husband`s name is David. We have been actively trying for a baby for 5 years and more. I desperately want to be a mom and I hope God will answer our prayers
My husband and I have been trying for 5 years, and we stopped infirtility treatments last year. When I was going to my doc, he told me I have a under mature left ovary and a over mature right ovary. What does this mean and how does it affect fertility?
