In Canada, half of babies born today have a mother over 30 years old, twice as many as in 1975. In 2019, in Quebec, the average age at childbirth is 30.82 years. This desire to have a child later has been particularly marked since the beginning of the 1990s. The place of women in the labor market and obtaining a stable professional situation largely explain this increase in age. average to motherhood. While this reality portrays a profound change in our society, we must keep in mind that it is more difficult for a couple to conceive as the mother advances in age.
Unlike men who constantly renew their sperm reserve, there are a limited number of eggs. When she is born, the little girl has 1 to 2 million. Over the years, this number continues to decrease. A 35-year-old woman only has 12% of her ovarian reserve left, and when she turns 40, it's only 3%. Female fertility therefore declines around the age of 35 and declines more rapidly after 37 years.
