Most experts define infertility as not being able to get pregnant after 1 year of trying — or not being able to get pregnant after 6 months of trying if you are 35 or older. Women who are able to get pregnant, but are unable to stay pregnant because of repeated miscarriages, may also be considered infertile. About 10 percent of women ages 14 to 44 in the United States have difficulty getting pregnant or staying pregnant, according to the Centers for Disease Control. If you are unable to become pregnant or have experienced multiple miscarriages, the Kofinas Fertility Group can help. A consultation and fertility workup can provide answers and help you and your doctor establish a fertility treatment plan.
