Luteal phase support

Progesterone given after transfer to support the lining.

Medicines

Luteal support is usually vaginal progesterone pessaries or gel, sometimes injections or tablets, started around the time of egg collection or before a frozen transfer and continued into early pregnancy. It compensates for the effect of IVF medicines on natural progesterone production. Follow the stop date your clinic gives rather than stopping early.

Also known as: progesterone support, luteal support, pessaries
