Single embryo transfer success rate

Single embryo transfer success rate 

 They found no statistically significant difference in live birth rate when comparing cumulative single embryo versus double embryo transfer rate (38.8 % vs. 42.9 %, P = 0.3). Compared to the eSET arm, the rate of multiple births was significantly greater in the double embryo group (0.8 % vs. 33.1 %, P < 0.001).

Depending on the patient, implanting two embryos can slightly increase the chance of at least one of those embryos implanting and resulting in a successful pregnancy. Implanting two embryos can also result in those adorable twins, which is particularly appealing to parents needing IVF to get pregnant. They often think they can get two kids in one try and not have to go through IVF again.

But a pregnancy with twins can be more dangerous than adorable. Multiple pregnancy – which we call a pregnancy of twins, triplets or more – is fraught with potential health problems for the children and mother.

Multiple gestation pregnancies have higher risks for low birth weight children and premature birth, which can result in infant mortality or other problems for the children. Problems can include needing special care at birth (short or prolonged neonatal intensive unit care) and facing long-term issues such as developmental delays, ongoing lung and gastrointestinal dysfunction, cerebral palsy and other debilitating problems.

The mother carrying twins has an increased risk of Caesarean section, which prolongs recovery and can result in hemorrhage during and after delivery. Worse, one or both fetuses may not survive to term and require removal. Carrying twins can also increase mom’s morning sickness, weight gain, and risk of developing gestational diabetes and blood pressure problems including preeclampsia. Further, the sleep deprivation, fatigue, marital and family stress created from caring for more than one baby has been shown to be far higher than when caring for one at a time.

Mothers and fathers have a choice: implant a single embryo or two. While it is possible to implant more than two embryos (remember Octomom?), few doctors will do that these days.

10 common questions about Single embryo transfer success rate

1What are the chances of twins with a single embryo transfer?
The prevalence of true zygotic splitting was 1.36%, and the researchers found that, compared to singleton pregnancies, using frozen-thawed embryos increased the risk of zygotic splitting embryos by 34%, maturing the blastocysts in the lab for a few days before embryo transfer increased the risk by 79%, and assisted
2What is the success rate of embryo implantation?
Any patient, no matter the amount of time between embryo freezing and thawing, can expect nearly the same potential for success as they experienced with the fresh IVF cycle that the frozen embryos came from. Women 35 years and younger have over a 60 percent chance of pregnancy per transfer
3Does transferring two embryos increase chance of pregnancy?
Implanting two embryos can reduce IVF success by a quarter if one of the embryos is of poorer quality, new research suggests. ... When a good quality embryo was transferred at the same time as a poorer quality one, the chance of pregnancy was reduced by 27 percent compared with transferring a single good quality embryo
4Can a single blastocyst split into twins?
There is an increased risk of identical twins with blastocyst transfers. ... Any couple wishing to avoid the chance of twins for any reason may choose single blastocyst transfer. In natural conception, fertilized eggs do not enter the uterus until five days after fertilization
5Can a single frozen embryo transfer result in twins?
Why single embryo transfers in IVF sometimes result in twins. ... However, despite performing SET, multiple pregnancies do happen due to a phenomenon known as 'zygotic splitting', when one embryo divides resulting in twins or triplets. It is more prevalent following SET than in spontaneous conception
6Can I poop after embryo transfer?
During the IVF embryo transfer procedure, Robert, my long-time ultrasonographer, has been telling patients for years: "Laughing, coughing, sneezing, peeing, pooping and walking do not knock the embryos out. ... Yes, you should relax and take it easy after an IVF embryo transfer. But no, bed rest is not necessary
7Is a blastocyst a baby?
During this time, it divides to form a ball of cells called a blastocyst. A blastocyst is made up of an inner group of cells with an outer shell. The inner group of cells will become the embryo. The embryo is what will develop into your baby
8Is it better to transfer 1 or 2 embryos?
Why a 2 Embryo Transfer is Best! There has been a big push in the country to transfer only one embryo, mainly to avoid the risks of twins. So, if a patient has four embryos, the recommendation would be to transfer one at a time, until all four embryos would be transferred; as opposed to doing two transfers of two each
9How soon does an embryo split into twins?
Unlike the single baby, this fertilized egg cell will split into two separate embryos, and grow into identical twins. This remarkable event takes place during the first week after fertilization, and can happen at several different times: At the two cell stage on days 1 to 3. At the early blastocyst stage on days 4 to 6.
10Is FET more successful than IVF?
Most definitely. The fasted growing trend in IVF is egg freezing but for us FET cycles have increased faster than any other treatment. In Cardiff, FET cycles increased by 32% (2017 vs 2018) and we've already done 20% more in 2019 compared to the same time in 2018!
