age-related fertility decline

Age-related fertility decline refers to the gradual decrease in a person's ability to conceive as they get older, mainly due to changes in reproductive health. In women, the number and quality of eggs in the ovaries diminish over time, especially after the mid-30s, reducing chances of conception and increasing risks of miscarriage or genetic issues. In men, sperm quality and quantity decline more slowly but can also reduce fertility with age. Overall, biological changes with age mean fewer viable eggs and sperm, making conception more difficult and increasing the likelihood of fertility challenges.
