Medicaly-assisted procreation or in Vitro Fertilization (IVF) represents a method of assisted reproductive technology.
The classic IVF represents embryonic fertilization technique - fertilization of the egg cell, in which the embryologist, in an appropriate container, and the presence of a suitable medium, leaves the egg with its surrounding and concentrate of semen, which then spontaneously fertilizes the egg cell.
This technique is commonly used in situations where there is no significant disruption of semen, and its advantages are allowing "natural selection" - it is left to the most potent spermatozoid from the group to fertilize egg cell in these special conditions.
Further development of embryos takes place in standard laboratory incubator.
Although there are clinics where nearly all cycles are performed by different technique (ICSI), it is considered that classic IVF certainly has its place when there are proper findings of semen, because it allows the natural selection of the best spermatozoid.
The disadvantage of this procedure is that it has low rate of success with major damage of semen (when ICSI is traditionally used). Sometimes, even in the case of proper semen, fertilization does not occur (fertilization failure), and it can happen that few spermatozoids fertilize one egg cell, thus creating genetically defective embryos.
Medically-assisted procreation or In Vitro Fertilization (IVF), represents a method of assisted reproductive technology (ART). A key feature of this technology is taking both male and female gametes (semen and egg cells) in appropriate manners, which are then combined in the lab (the so-called In Vitro conditions). After that, the created embryo is entered...Learn more
ICSI - intracytoplasmic sperm injection, is the technique of fertilization of the egg cell from the group of micro-manipulation techniques, where a single spermatozoid is injected directly into the cytoplasm of the egg cell...
The proper development of the embryo in the body of a women or in laboratory (in vitro) conditions, implies certain dynamics of the division of the fertilized egg, in which the third day after fertilization we usually get an eight-cell embryo...
