The treatment to follow varies depending on whether it is a fresh embryo transfer (after an IVF cycle) or a frozen embryo transfer.
With fresh embryos, patients follow a hormonal treatment based on applying injections to stimulate the ovaries during 10 days approximately. After retrieving the eggs, the patient starts taking progesterone vaginally or subcutaneosly.
With frozen embryos, patients have to prepare during 2 weeks with estrogens (in patches or tablets). Depending on the day of the embryo transfer, progesterone may be prescribed as well. In some cases, the patient follows a natural cycle, without using estrogens.
