Infertility is a disease that impacts one in eight Americans. The current definition of infertility is the inability to conceive after one year of trying or after six months if the female is over the age of 35. While traditionally thought of as a women’s issue, infertility impacts men as well. One-third of the causes of infertility are female-related, one-third are male-related, and one-third are unknown causes.
In the US, Americans are starting families later in life, when it is harder to have a baby. Unlike men who generate new sperm throughout their lives, women are born with their lifetime supply of eggs. As a woman ages, the number of remaining eggs decreases, with a sharp decline in egg quantity seen in her mid-to-late thirties. Along with egg quantity, egg quality also declines and there is an increased risk of pregnancy loss.
