Embryos are transferred to the surrogate’s uterus 3-5 days following egg retrieval and 2-3 days of rest is recommended for optimal outcome.
The surrogate will be given daily progesterone injections and/or suppositories in order to maintain an optimal environment for implantation and approximately 7-10 days after the embryo transfer will undergo a pregnancy test.
A positive test indicates that implantation is taking place. In such an event, the hormone injections will be continued for an additional four to six weeks.
An ultrasound examination will be performed to confirm a clinical pregnancy. If the test is negative, all hormonal treatment is discontinued, and menstruation will follow within three to 10 days.
If the surrogate does not conceive, the aspiring mother may have her remaining embryos (if any) frozen, be thawed and transferred to the uterus of another woman at a later date. If the surrogate does not conceive, after both the initial attempt and subsequent transfer of thawed embryos, the infertile couple may schedule a new cycle of treatment.
