IVF procedure (program)

Dr.-Bernard-Artur-IVF-Hungary-BudapestFor pregnancy to occur, an egg must be fertilized with sperm. Normally, a single egg is released from the ovary and fertilized in the Fallopian tube.

However, during IVF, the union occurs in the laboratory after the egg and sperm have been collected. This requires a number of steps which are outlined below.

During the initial visit you will receive detailed information about these important steps.

Follicular stimulation and monitoring

Dr.-Kovács-Péter-Follicular-stimulation-and-monitoringTo control the time of egg release and to increase the chance of collecting more than one egg, the woman will be prescribed fertility drugs, selected for her individual situation. These drugs will be administered at home. To check that egg development is progressing at a satisfactory rate, the woman will need to undergo vaginal ultrasound scans of the ovaries. At the appropriate time when the follicles have grown sufficiently she will take additional medication (HCG) to complete the egg maturation process just prior to undergoing oocyte (egg) retrieval. Sufficient development and adequate number of eggs must be present in order to proceed to retrieval. The cycle will be canceled at this point if the developing follicles are too few.

Oocyte (egg) retrieval

Dr.-Kovács-Péter-Oocyte-egg-retrievalEgg retrieval is a minor ambulatory procedure performed with intravenous sedation. Under ultrasound control a needle is inserted through the vagina into the ovaries. The follicles containing the eggs are punctured and aspirated. If the procedure is successful numerous eggs will be obtained.

These eggs are inseminated by the processed sperm (obtained by masturbation shortly after the eggs were recovered) in the IVF laboratory where fertilization will take place. The fertilized eggs (embryos) are kept in the incubator until the embryo transfer.

Embryo Transfer (ET)

Embryo-Transfer-ET-IVF-Pregnancy-Center-HungaryIf the embryos have developed properly, up to three of them (depending upon patient characteristics/ preference) are replaced into the uterus by means of a small tube. This procedure is painless.

Embryos in excess of three will be frozen and stored for possible transfer during subsequent cycles. Following transfer, implantation may occur with a resultant pregnancy. However, as in natural reproduction, many embryos do not survive. In general, the success rate is about 25-30% per cycle in centers throughout the world.
