In ART (assisted reproductive technology) cycles, embryos are transferred to a woman's uterus
after in-vitro fertilization (IVF) in a laboratory. Usually, hormones (progesterone) are
given to the patient after transferring the embryo, as a supplement, in order to mimic the
natural hormones that would normally be secreted in an unassisted pregnancy. This study will
identify whether additional gonadotropin-releasing hormone (GnRH-agonist) administration, a
natural hormone secreted from the hypothalamus, will improve the clinical pregnancy and live
birth rates when using IVF.
