In Vitro Fertilisation Treatments

In Vitro Fertilisation procedure: The eggs are placed in a Petri dish and inoculated with 100.000 sperm per egg. Mixture is placed in incubators and following day eggs are checked for fertilization. In normal circumstances with a good sperm count approximately 70/80 percent of the eggs are fertilized. The eggs continue to divide and two days after the egg recovery they achieve 4 cell stage. On the third day, embryos reach 8 cell stage. Same day, healthiest three embryos are taken and placed in the women’s uterus by plastic catheter. In our center all the embryo transfers are performed under careful ultrasound guidance in which uterus is seen easily, and embryos are transferred exactly 2cm below the top of the cavity. This gives the best pregnancy chance. Pregnancy test is performed 12 days later. In order to increase the success rates, certain procedures are performed as necessary. For example,some embryos have a thick outer layer which prevents the embryos to attach the lining of the womb. To solve this problem, the laser is used to thin out the outer layer. This is called the Assisted Hatching. Also in some cases, the embryos are transferred not 3 but 5 days after the egg recovery to select best embryos. 5th day embryo is called blastocyst and this procedure is called blastocyst transfer. .In some In Vitro Fertilisation/ICSI cycles several embryos are produced and three of them are given, remaining good quality embryos are frozen for the future use. Embryo freezing is a well developed technique today that allows women to have another chance of pregnancy. Embryo transfer is much cheaper than regular cycle because no medication is used and no anesthesia is required. Embryos are frozen for several years and can also be used in the future if the couple desires another child or if the first cycle is unsuccessful.In Vitro Fertilisation success rates are the percentage of all In Vitro Fertilisation procedures which result in a favorable outcome. Depending on the type of calculation used, this outcome may represent the number of confirmed pregnancies, called the pregnancy rate or number of live births, called the live birth rate.Due to advancement in reproductive technology, the In Vitro Fertilisation success rates are substantially better today than they were just a few years ago.
