Advanced maternal age: how age affects fertility

As women reach an advanced maternal age, their fertility naturally declines. This is because women are born with a finite number of eggs, and the number of eggs in their ovaries decreases as they get older. Additionally, the quality of eggs can decline with age. This is because older eggs are more likely to have chromosomal abnormalities. Our New Jersey fertility doctor helps women understand why it’s harder to conceive as women get older.

The decline in the number of eggs in a woman’s ovaries is one way age affects fertility

The number of eggs in a woman’s ovaries starts to decline at around age 30. By age 40, the number of eggs has decreased by about half. By age 50, most women have gone through menopause, which means that they no longer have regular menstrual cycles and are no longer able to get pregnant naturally. The quality of eggs can also decline with age. Older eggs are more likely to have chromosomal abnormalities, which can lead to miscarriage or birth defects. The risk of chromosomal abnormalities increases significantly after age 35.

The decline in fertility with age is due to several factors, including:

• A decrease in the number of eggs in the ovaries
• A decrease in the quality of eggs
• A decrease in the ability of the ovaries to release eggs
• Aging of the uterus that may occur due to scarring or infection

Advanced maternal age increases the risk of miscarriages and babies with birth defects

At an advanced maternal age, women are at an increased risk of having a miscarriage or a baby with a birth defect. The risk of miscarriage increases significantly after age 35, and the risk of birth defects increases significantly after age 40.

The risk of miscarriage is about 15% for women under age 35. The risk of miscarriage increases to about 20% for women between ages 35 and 39, and to about 30% for women over age 40.

The risk of birth defects is about 3% for women under age 35. The risk of birth defects increases to about 5% for women between ages 35 and 39, and to about 10% for women over age 40.

Fertility treatment options for women who want to conceive at an older age

There are a number of fertility treatment options available to women who are struggling to conceive at an older age. These options include:

• In vitro fertilization (IVF): IVF is a procedure in which eggs are retrieved from the ovaries, fertilized with sperm in a laboratory, and then transferred back into the uterus.
• Egg donation: Egg donation is a procedure in which eggs are donated by another woman, and then fertilized with sperm and transferred back into the uterus.
