There are several reasons for the decline in fertility with age:
Ovarian Reserve: Women are born with a finite number of eggs, and this reserve decreases over time. Egg Quality: The quality of eggs diminishes as a woman ages, leading to increased chances of genetic abnormalities. Hormonal Changes: Hormonal fluctuations can affect ovulation and menstrual cycles. Uterine and Cervical Aging: Changes in the uterus and cervix can impact the ability to conceive and maintain a pregnancy.
