Age significantly impacts fertility for both men and women:
- Women: Female fertility declines with age, particularly after the age of 35. The number and quality of eggs decrease, leading to a higher risk of infertility, miscarriage, and chromosomal abnormalities.
- Men: While men can father children later in life, male fertility also declines with age. Sperm quality, including motility and morphology, can decrease, leading to challenges in conception.
