Frozen embryo transfers entail the use of thawed embryos that were frozen in a previous in vitro fertilization (IVF) cycle. Frozen embryos could stay frozen for up to 10 years, though freezing techniquesand quality of the embryos influence the survival rate of the embryos. While a fertility patient will have the little control over the outcome of the embryo thawing process, there are several ways she could get ready for a frozen embryo transfer to make better her odds of successful pregnancy.
Keep in mind before a Frozen Embryo Transfer
- Optimize your overall health: The regular physical examinations, gynecological evaluations, and a thorough workup with your fertility doctor are suggested before a frozen embryo transfer cycle. Take vitamin supplements, incorporating folic acid. Also, fertility patients should quit smoking and limit alcohol consumption to endorse the best outcomes.
- Be aware of developing health conditions: Hypertension and diabetes could get worse during pregnancy and pose the risks to the fetus.
- Take frozen embryo transfer success rates with a grain of salt: The rates of success rely on the number of cycles a clinic performs and the complexity of cases accepted into the clinic. Comprehending how age and diagnosis cut offs influence IVF success rate data is important for observing the bigger picture. There are many other factors that influence your personal success rate including body mass index (BMI) and underlying fertility conditions are some examples.
- Consult a trusted fertility doctor for a realistic assessment on quality of your frozen: embryos. Embryos frozen using the slow-freeze techniques are at the greater risk of perishing during the thaw process. Embryos frozen with vitrification endure less ice crystal formation and are at less risk of cell rupture during the thaw process. Better quality embryos will have a higher survival rate as well.
Before a patient bears a frozen embryo transfer, it is recommended checking the hormone levels to be sure they are balanced, screening for thyroid disease, and examining the uterine cavity. Particularly if the patient has been pregnant and delivered a baby through c-section (caesarian section), scar tissue could have an effect on the uterus as well and can form it difficult for the embryo to attach. Fertility patients concerned about the risks of chromosomal abnormalities or have had an ineffective frozen embryo transfer should converse to their fertility doctor about preimplantation genetic screening (PGS).
- How many embryos should you transfer for the best chances of IVF success?You may get surprised if transferring more embryos with IVF might boost your chances of IVF success. This is an issue presently being studied at the length by fertility researchers.
If you are under 35, moving more than two embryos could enhance your chances to becoming pregnant. On the other hand, multiple embryo transfer can also enlarge your chances of having multiples. No matter what your age is, ask your doctor if you are eligible for single embryo transfer, an IVF option that many experts now commend.
