Which factor can significantly affect female fertility?

Age and hormonal imbalances are critical factors that can significantly impact female fertility. As a woman ages, her reproductive system undergoes various changes, which can lead to a decline in the quantity and quality of her eggs. This decline typically begins in a woman’s late 20s to early 30s and accelerates as she approaches her 40s. Additionally, hormonal imbalances can disrupt the menstrual cycle and affect ovulation, making it more challenging to conceive. Hormones like estrogen and progesterone must be in proper balance for ovulation to occur regularly and for the body to support a pregnancy. Therefore, understanding the relationship between age and hormonal changes is essential for assessing female fertility effectively.
