Female fertility begins to decline gradually around age 32 and decreases more rapidly after age 37.
This decline is due to a natural decrease in the number and quality of eggs a woman produces. The quality of a woman's eggs is also affected by lifestyle factors such as smoking, alcohol consumption, and exposure to environmental toxins.
While the decline in fertility is gradual, it becomes more significant in the late 30s and 40s. By age 40, a woman's chances of getting pregnant naturally are significantly lower than they were in her 20s and 30s.
It is important to note that these are just general trends and individual experiences can vary. However, understanding the age-related decline in female fertility can help women make informed decisions about their reproductive health.
