Question

Quizplus · Accepted Answer

The age of the egg is the biggest biological barrier to pregnancy in an infertile couple trying to conceive. As women age, their eggs become more prone to genetic abnormalities and chromosomal disorders, making it harder for a fertilized egg to develop into a healthy embryo. This can increase the risk of pregnancy loss or birth defects. While factors such as the amount and quality of sperm and the age of the male providing sperm can contribute to infertility, they are not typically the biggest barriers to achieving a pregnancy. The age of the female gestator can affect pregnancy outcomes, but it is not the primary factor in achieving fertilization and conception.
