Luteal support

Luteal support replaces hormones the body may not produce adequately after stimulation or in a medicated frozen cycle. It typically continues until the pregnancy test and, if positive, often into the first weeks of pregnancy as the clinic advises. Do not stop it early on the basis of bleeding or a home test — call the clinic.

Also known as: progesterone support, luteal phase support
