I’m 37 and would like to start trying for a baby—have I waited too long

Increasing numbers of women are delaying their first pregnancy until they are in their late 30s and early 40s and, as with any life choice, this has advantages and disadvantages. The main concern for women is that fertility does decrease with age, and so for some women it may take a little longer to get pregnant, or they may find that they need to look at ways of assisting conception (see p.27). Also, the risk of having a baby with a chromosomal abnormality such as Down syndrome increases as you get older, rising from a 1 in 356 chance at 35 years old to a 1 in 240 chance at 37 years old
