How Age Impacts Fertility

Age plays a significant role in a couple’s ability to conceive. While both men and women experience changes in fertility as they grow older, the impact is more pronounced in women.

Why Does Age Matter?

Fertility is not constant throughout life. As we age, natural biological changes reduce the chances of conception. This is primarily due to the decline in egg quality and quantity in women and gradual sperm quality changes in men.
