You have a number of eggs since you were born. And you cannot produce more eggs in your life. Since you come into puberty, your body starts to release an egg a month (can be more). Over time, the number and the quality of the eggs can decrease, especially when you are old.

When the egg is fertilized by a sperm, and implant in the womb, you get pregnant. If the egg is not fertilized by a sperm, you have a period. Your body stop releasing eggs when you come into menopause.

Chemotherapy affects fertility

Chemotherapy can affect your fertility when you have not come into menopause. It affects your ovaries and egg’s quality.

Your fertility after chemotherapy depends on the types of medicines, doses, and your age. You may stop having periods when the treatment start, then start having them months or years after the treatment. If your periods return, it does not mean your fertility is normal and you can get pregnant.

Age

You are more likely to get pregnant after chemotherapy if you are treated for cancer before 30. If you are 40 or older, you are more likely to come into menopause after chemotherapy. If you are close to menopause, you cannot get pregnant after chemotherapy.

Types and doses of medicines

Some certain types of drugs can make it hard for you to be in pregnancy, such as:

Some women can have a normal menstrual cycle and get pregnant after hormonal therapy, but some cannot.
