How hormone medicine can help

Hormones are chemicals that your body makes naturally. Each type of hormone has its own function. In some cases, hormones are used for assisted reproductive treatment (ART). Hormone medicine can help:

• Make more eggs. Follicle-stimulating hormone (FSH) causes the ovaries to make more mature eggs each month. Normally 1 egg matures each month. Note that this does not make you run out of eggs faster.

• Trigger ovulation. Human chorionic gonadotropin (hCG) is used to cause ovulation. This can help by controlling the timing of when an egg can be fertilized after sex. It may also be used for ART.

Hormone medicine can also help change the levels of other hormones. To help you ovulate, you may be given medicine to treat:

• Anovulation or oligovulation. This is when you don't ovulate or don't ovulate regularly.

• High levels of the hormone prolactin. This can stop ovulation from occurring.

• An imbalance of thyroid hormone levels. This can cause problems with fertility. It can also cause miscarriage.
