Classic IVF

IVF comes from In Vitro Fertilization, meaning fertilization in laboratory, artificial conditions, outside of the mother’s body.

The basic principle is removal of the mature eggs from ovaries, followed by their fertilization outside the body (in laboratory conditions) by sperm from partner or donor and transfer of one or more embryos back to the uterus.

The classic IVF is the embryological technique for the fertilization of the egg cell, in which the embryologist uses appropriate vessel and in the presence of the appropriate medium leaves the egg cell in the environment with the spermatozoa, which then spontaneously fertilizes the egg cell.

This technique is commonly used in situations where sperm disturbance exists, and its benefits are that it allows “natural selection” or that it leaves the most sophisticated spermatozoid from the group to fertilize the egg cell in these special conditions.

Further development of the embryo takes place standardly in the laboratory in the incubator.

Although there are centers in which almost all cycles are performed by another technique (ICSI), it is considered that the classic IVF certainly has its place, because it allows the natural selection of the best spermatozoa.

Disadvantage of this procedure is that it yields a low success rate for cases with significant sperm damage, in this cases ICSI is standard procedure.
