For women fertility naturally declines with age because of a decrease in both the number and quality of eggs. Women are born with a fixed number of eggs. As they age this number decreases. The quality of eggs also declines, leading to a risk of chromosomal abnormalities, which can affect embryo development and increase the chances of miscarriage. For men age also has an impact although it is generally less significant. Sperm quality may decline over time affecting fertilization and embryo health.
