“Why can’t I get pregnant at 42” is a question frequently asked by women over the age of 40 who are trying to conceive. Fertility declines with age, and this decline becomes more noticeable after age 40.
The main reason for this decline in fertility is the decrease in the number and quality of eggs. As a woman ages, her ovaries produce fewer eggs, and the eggs that are produced are more likely to have chromosomal abnormalities. These abnormalities can make it difficult for the eggs to be fertilized or to implant in the uterus.
