Preparing for the embryo transfer procedure
Transferring your embryos into the uterus is a relatively simple procedure. Much more effort is required to prepare the body of the expectant mother. The main stage is the formation of the desired endometrium, it is achieved by the correct balance of drugs and the duration of the course. It is the endometrium that determines whether the embryo can attach to the walls of the uterus and turn into a long-awaited baby.
How embryo transfer occurs
About the middle of the cycle into the cavity The highest quality embryo obtained will be transferred to the uterus. The embryo can be transferred immediately after the IVF procedure - this is the transfer of fresh embryos, or some time after the procedure - the transfer of frozen embryos. The embryo is implanted within a few days, and blood tests are usually performed 10 to 12 days after the transfer. To make sure that pregnancy has occurred, a repeat test is performed a few days later. The standard test is beta-hCG or BHCG, a blood test that looks for hormonal changes that occur during pregnancy. A positive test will be a reason for the first great joy, and very high results could mean twins!
When the hormone level is over 1500 units, the fetus can already be seen on a transvaginal ultrasound. And with an indicator of 4,000 units, the baby can be seen on a transabdominal ultrasound.
On the first attempt, the highest quality embryo is transferred. The next attempts are made with the remaining embryos, the quality of which may be lower. Therefore, it is important to approach the first transfer with maximum responsibility and proper preparation.
Correction of embryo development
< p id="">Now it is possible to do preimplantation genetic screening - PGS or PGD. It will help correct the course of embryo development and identify problems. Other ways to increase the chances of pregnancy include embryonic “glue”, intracavitary injections, and oral drug support. Sometimes it takes a little more time to prepare properly. The advantage of freezing embryos is that you can wait for the best time to transfer. Modern methods of embryo freezing or “vitrification” are so effective that many clinics prefer to use frozen embryos.
Transferring two embryos at a time
All over the world, clinics use two variants of embryo transfer protocols. The first option is more often used by American reproductive specialists—one embryo per attempt. Doctors in Europe and Russia are considering transferring two embryos at a time. The number of embryos transferred does not increase the chance of pregnancy. Clinical data show that the transfer of several embryos increases the likelihood of twins or triplets, and the number of pregnancies occurring is no more than with the transfer of a single embryo. Therefore, each family chooses the appropriate option for itself.
Risks of multiple pregnancy
Multiple pregnancy is accompanied by risks. Babies are forced to share space and food, which affects the well-being of the mother. Often such a pregnancy leads to premature birth. More than 60% of twins are born before 37 weeks, that is, premature, as they no longer fit in the uterus. In multiple pregnancies, preeclampsia, gestational diabetes are common and, unfortunately, placental abruption sometimes occurs. Therefore, it is very important to take the diagnosis of embryos responsibly and follow the doctor’s recommendations when preparing the mother’s body.
