In vitro fertilization (IVF) is a method of fertilizing a woman’s mature oocytes, removed by puncture outside the woman's body and brought together with a man’s sperm, in a medical laboratory. The produced embryos are transferred into the woman's uterus or frozen for subsequent embryo transfer (cryopreservation).
A variation of the classical In vitro fertilization is a method called ICSI, which is similar to IVF, but what makes it different, is that with the aid of special equipment, one selected sperm cell is injected in the egg.
ICSI (intracytoplasmic sperm injection) is mostly applied when the couples are facing the so-called male factor –male infertility or, or more precisely said: Degraded sperm parameters of the partner.
When there is a good spermogram /semen analysis/ and the quantity of the eggs removed is big enough, it is possible in laboratory conditions to be applied a combination of the two fertilizing methods.
In both procedures, classic In vitro fertilization and ICSI, it is possible donor sperm or eggs to be used after the patients have signed the necessary documents.
