Egg culture with Blastocyst technique

In vitro culture technique (IVF) until adulthood has increased in vitro fertilization results from 30-35% to 50-60%.

Less expensive, high success rate

It was announced by the Central Obstetrics Hospital after implementing this new method for 12 couples and there were eight pairs of results. This technique applies to women who do not ovulate. Satisfactory oocyte (mature eggs) after aspiration will show healthy sperm in vitro and then reared in the appropriate environment. After 5-6 days, when the speed and morphology are normal, the doctor will inject into the uterus.

Dr. Nguyen Viet Tien, director of this hospital, said that farming with blastocyst technique is not difficult but requires very high technique, suitable chemical environment. The lab is not guaranteed to have results.

This technique has been studied and tested in advanced countries, first conducted in Vietnam. The rearing stages were carried out in the incubator, stable temperature of 37oC and in the most suitable environment, almost like in the womb of the woman.

In the past, with in vitro fertilization, embryos were transferred at 4-8 cells, meaning that 2-3 days after embryo culture was transferred into the uterus. This technique is less expensive but the success rate is not high, only approximately 25-30%. Meanwhile, blastocyst embryo transfer technique has a success rate of up to 50-60%.

Moreover, this culture will help select embryos, making the embryo transfer into the mother's uterus less, thus limiting the risk of multiple pregnancies. It also means that a series of maternal and fetal diseases caused by multiple pregnancies can be reduced, such as: easily causing pre-eclampsia, placental placenta, placenta praevia and the risk of premature birth for handicapped children. Infant.

New direction of hospitals treating infertility

The drawback of this technique is that it only applies to qualified labs and good quality workpieces. Bad embryos that can only be kept until the third day are broken.

This technique is not the same as the cultivation of young eggs. The cultivation of young eggs is like raising premature babies. In such conditions, it is still possible to grow, but up to two thirds of cases are malformed, only 1/3 of children develop normally. For premature babies, only in passive cases, which means that it cannot be kept longer, it is compulsory to give birth prematurely.

The incubation of young eggs for culture is easier than that for mature eggs (at this time the patient is easily irritated by ovarian ovulation) but the success rate is low and no one dares to claim that this culture leaves a malformation for children or not. According to Dr. Tien, this method should not be widely deployed, let some centers do well and expand to other centers to launch applications.

Blastocyst technique, according to Dr. Tien, is very superior. Currently, Vietnam has just piloted some cases. In the future, if this technique is stable, a high success rate will be deployed to infertility centers throughout the country.
