IVF/ICSI
ICSI > Intra Cytoplasmic Sperm Injection – it is generally performed in addition to an in vitro fertilisation procedure to extract often several oocytes from a woman.
IVF/ICSI is the procedure that is fulfilled naturally. Women are inserted hormones to raise the quantity of maturating eggs. Egg cells are observed with the help of ultrasound. When they reach the size from 18mm to 20mm, chorion gonadotropic hormone is injected to fasten the maturation that results in 36 hours. By this time, patients are prepared for the operation and under anesthesia egg cells are retrieved by follicular injection via ultrasound.
In between the man gives his semen. Semen is estimated, and then the most mobile and normal will be picked up and used in the procedure.
For a normal IVF procedure, egg cells are placed into Petri dish, and take root in the ratio 100.000 semen for an egg cell. Mixture is put into an incubator and next day, after egg cells are diagnosed in normal conditions and if semen is of good quantity from 70 to 80% off cells are fertilized. Egg cells continue to separate and in 2 days after recovery they reach 4th cellular. On the third day embryos reach 8th cellular. The same day, 3 healthiest embryos are taken and placed into the woman with the help of plastic catheter. In our center embryo transfer is fulfilled, which is carried out under careful ultrasound observation. Embryos are placed 2 centimeters below alvus. It results in more success for pregnancy. In 12 days pregnancy tests are done.
ICSI procedure
During IVF procedure semen and egg cells are put into the same membrane and wait until semen fertilizes an egg cell. Fertilization will not happen if the quantity of semen is not enough. Even if the semen is normal there is a variety that fertilization will not happen due to unknown reasons. During ICSI procedure, separated semen is taken and micro injected into the egg cell, this results in guaranteed fertilization.
ICSI procedures become more and more popular because they expel the probability of unsuccessful fertilization of egg cell by semen. With the help of the usual ICSI procedure the quantity of pregnancies rose. Unlike western clinics we do not take additional ICSI expenses. Sometimes semen can not be found due to absence of tube between testicle and penis. In this case semen can become active with the help of testicle biopsy. This is called TESE procedure (testicular semen). Semen that is received this way also can be used.
Rising pregnancy rate
In order to raise success ratio, a couple of processes need to be done. For example, some embryos have thick outer shell that prevents embryo replanting. That is why laser is used to make this outer shell thinner. In some cases in order to get better embryos, eggs are transferred not in 3 but in 5 days. 5 days embryos are called blastocysts, consequently the process is called blastocyst transfer.
In case of failed IVF/ICSI attempts, chromosomes may cause embryo abnormalities. In this case PGD procedure is done (Preimplantation Genetic Diagnosis). With the help of this technology one cell is cautiously retrieved from 4-cell embryo and is researched to analyze chromosomes. Then embryos with normal chromosomes are chosen and are transferred to a woman on the next day.
In several IVF/ICSI cycles several embryos are transferred. After 3 of them are used, other high quality embryos are frozen to be used in the future. Today, embryo freezing is a widespread technology that gives women a chance for pregnancy. Embryo transfer is not as expensive as regular cycle because nor medical treatment nor anesthesia is needed. In case couple wants one more child and if the cycle fails to be successful, it is possible to freeze embryos for several years.
