What is the relationship between female age and fertility?
Starting in a woman’s late 20’s, fertility begins to slowly decline. After the age of 35-37, this decline accelerates and, by the time a woman reaches her early 40’s, she has only a 5% chance of conceiving each month. For this reason, fertility specialists often recommend seeking treatment after only 6 months of trying if the woman is over 35 years old. Women over 40 should consider consulting with a fertility specialist as soon as they are ready to conceive.
