Final answer:
Age can affect male or female fertility through the decline in the quality of eggs and sperm as individuals age.
Step-by-step explanation:
One way in which age can affect male or female fertility is through the decline in the quality of eggs and sperm as individuals age. In females, as they get older, the number of eggs decreases and the remaining eggs may have a higher chance of genetic abnormalities. This can make it more difficult to conceive and increase the risk of miscarriage. In males, the quantity and quality of sperm may decrease with age, which can affect fertility and increase the likelihood of genetic disorders.
