Best Doctor List Near You for Frozen Embryo Transfer (fet) in San sebastian

Frozen embryo transfer (FET) is a procedure in assisted reproductive technology (ART) where previously cryopreserved embryos are thawed and transferred into a woman's uterus to achieve pregnancy. This technique is commonly used in conjunction with in vitro fertilization (IVF) when extra embryos have been frozen for future use, allowing patients to avoid undergoing additional ovarian stimulation and egg retrieval procedures. The process involves several steps: first, the embryos are carefully thawed and assessed for viability. Simultaneously, the recipient's uterus is prepared through hormonal medication, typically including estrogen and progesterone, to create an optimal environment for embryo implantation. Once the uterine lining is adequately prepared, the thawed embryos are transferred into the uterus using a thin catheter inserted through the cervix. Frozen embryo transfer is beneficial for patients who have excess embryos from a previous IVF cycle, those undergoing fertility preservation, or those who wish to delay pregnancy for personal reasons. It also provides a chance for additional attempts at conception without the need for a new IVF cycle. However, FET carries potential complications. The success rate can be influenced by the quality of the thawed embryos and the health of the uterine lining. There is a risk of embryo damage during the thawing process, which may reduce the likelihood of implantation and pregnancy. Additionally, the process of preparing the uterine lining with hormonal medications can lead to side effects such as mood swings, bloating, or headaches. While FET offers a practical and less invasive option for achieving pregnancy, the procedure's success depends on several factors, including embryo quality and uterine receptivity.
