The science of reproductive medicine is constantly evolving in the realms of fertility treatment. With the guidance of Mexico’s knowledgeable IVF clinics, you can choose the most effective fertility treatment that will help make way for a new life. Many fertility specialists, including IVF experts in Puerto Vallarta recommend frozen embryo transfer method for patients who wish to avoid the discomfort and inconvenience of ovulation induction and egg retrieval, as well as their accompanying high-priced fees.
Embryos from IVF treatment in Mexico can be frozen for use in later treatments or donated to other infertile couples with embryo donation. Cryopreservation stores the embryos in liquid nitrogen. A Frozen Embryo Transfer Cycle or embryo freezing in Mexico is the process of thawing a previously frozen embryo and implanting it into a woman’s uterus to successfully establish pregnancy. IVF treatment using cryopreserved embryos follows the same procedure as newly fertilize embryos.
The Frozen embryo transfer method in Mexico has an equally high success rate and there is no increased rate of abnormalities using frozen embryos. Patients are often encouraged to choose the cost-effective route of freezing their embryos as a guarantee in the event that the first embryo transfer fails, or pregnancy is not carried out to term. The cost of the IVF with frozen embryo transfer in Mexico is the driving force for many oversees couples who are looking for an affordable solution to their infertility problem. Frozen embryos can be frozen and stored for several years, reducing the stress of further treatments.
FET Procedure
The Frozen Embryo Transfer (FET) process using donor embryos is the same as the process using your own embryos. Once the pituitary gland is suppressed, estrogen is given. Estrogen thickens the uterine lining. Estrogen can be given as pills, patches, or even injections. The uterine lining is monitored with transvaginal ultrasound. Progesterone is introduced as a vaginal suppository or as injections.
The number of days progesterone is given before the transfer must match the stage of embryo development. Synchronization is significant in embryo donation cycles.
Once the uterine lining has been prepared, the frozen embryos are thawed and placed into the uterus. The embryo donation recipient continues to take estrogen and progesterone until a pregnancy test is done. If she is pregnant, she continues both the estrogen and progesterone until the 11th week of pregnancy.
If a woman has regular, ovulatory menstrual cycles, a frozen embryo transfer can be performed without the use of hormone preparation.
Who Can Benefit from Frozen Embryos?
IVF treatment is not always successful on the first cycle. Freezing eggs allows couples to attempt a second cycle without repeating the egg collection procedure. Fertility drugs can cause ovarian hyperstimulation syndrome in some women. Women who are at risk of OHSS are advised to freeze all of their eggs to be used in later assisted reproductive treatments. Cryopreservation is also utilized in Mexico by couples who wish to have a further child or whose health may affect their future fertility.
Embryo Freezing Method
Embryo cells contain water, which must be removed prior to freezing so as to prevent ice crystal formation. The embryos are then mixed with a cryoprotectant fluid, and put into a glass ampoule. They are stored in liquid nitrogen at a low temperature to preserve the quality of the embryos.
Embryo Thawing Method
To thaw frozen embryos, they are removed from the ampoule and brought to room temperature. The cryoprotectant fluid is gradually removed and carefully diluted with water. When the embryos are fully resumed to room temperature, they are transferred to the recipient mother.
