How Many Embryos Should I Transfer?
The process of In-vitro Fertilization (IVF) treatment in Pune or any assisted fertility treatment for that matter, is not only sensitive but complex too. It requires total mutual understanding, empathy, and harmony between the partners. It is sensitive because it is related to an individual's own life and involves many delicate decisions. The most difficult question for the couples is obviously about the transfer of embryos. "How many embryos should be transferred?"
In recent times the world has seen revolutionary development in the IVF treatment in Pune process and Assisted Reproductive Technology (ART). As such the treatment has become much more secured and has witnessed better success rate, per embryo transfer. The process of cryopreservation (freezing) of embryos is remarkably superior. It is now possible to do cryopreservation of additional embryos in case a future pregnancy attempt is required. Therefore, the fertility specialists are now able to guarantee better success in pregnancy rate. This advancement has led to the decrease of triplet and quadruplet pregnancies. However, the transfer of two embryos is still commonly done in order to keep the chance of having twins.
It has been proved that multiple pregnancies pose a big threat to a woman's health and fetuses. There are chances of complications such as pre-eclampsia, preterm labor during pregnancy. The risk of gestational diabetes cannot be ruled out. Similarly, the percentage of premature delivery is higher. Due to the high risk to the mother and baby, doctors avoid multiple pregnancies as far as possible. If higher-order multiple pregnancies take place it may be possible to minimize the danger for the woman and fetus. This helps to have a singleton or twin pregnancy with the help of the ultrasound method. Nevertheless, the risk associated with pregnancy cannot be ruled out. Besides due to some religious or cultural compulsions and taboos many couples do not opt for multifetal reduction.
In this backdrop, we find certain guidelines in respect of the number of embryos to be transferred in an IVF treatment in Pune. They are just indications suggesting how many embryos could be transferred, depending on the day of transfer, quality of the embryo, age of the patient, prognosis category, and so on. But these are just indicatives and they serve only as a help to the patient and doctor. Generally, the prognosis is thought to be favorable in the case of the first IVF cycle. In this case, the embryos are found to be of good quality and there are chances of having surplus embryos available for freezing. If a couple is having successful IVF earlier, the prognosis is considered to be favorable. However, the embryologist recommends the transfer of fewer embryos if the transfer is taking place at the blastocyst stage, i.e. after 5-6 days after fertilization. This is because if an embryo reaches the blastocyst stage in the laboratory it should get a better chance of implanting. In the case of women with advanced age, the doctors would suggest the transfer of more embryos. Doctors may also increase the number of embryos to be transferred if the previous IVF cycle has not been successful.
Nevertheless, it is important for the patient and the doctor to determine how many embryos to be transferred. They need to make a conscious decision in this regard. The wannabe parents of course have the choice to decide whether to transfer one embryo or two of them. But they need to discuss with the physician properly in order to ensure the best pregnancy outcome.
At Xenith, with embryos of each patient being cultured separately and very high blastocyst formation rate, we usually transfer one or two embryos in order to keep the risk of multiple pregnancy rates low, at the same time maintain very high success rates.
