Why Do Surrogates Need to Take Medications for Pregnancy?

Because the pregnancy is not naturally conceived, surrogates take hormone supplements in order to prepare their uterus for an embryo. Surrogates are required to have medications in order to:

Coordinate the menstrual cycle of the surrogate to ensure her uterus is primed and ready to accept the embryo(s)

Prepare the surrogate’s uterus for pregnancy by providing two important hormones: estrogen and progesterone. Taken in sequence, these two hormones are meant to stimulate the surrogate’s natural cycle. This combination maximizes the chances of pregnancy and helps to prevent a miscarriage
