In vitro fertilization (IVF)

In vitro fertilization (IVF) was originally developed as a treatment method used when there is a fault with the fallopian tubes. Nowadays, IVF is the most efficient treatment method regardless of the causes of infertility. With each couple in question, this treatment also allows us to obtain new information on the background of their infertility. The IVF cycle is started with hormonal treatment, with the objective of maturing several follicles simultaneously in the ovaries. Thus, several eggs can be retrieved, of which 2/3 are fertilized and begin to multiply. There are many factors, however, affecting the number of eggs and their fertilization. The treatment is carried out by maturing the follicles for about 10 days with hormonal injections. The response to these injections is followed by ultrasound scans. After this, ovum pick-up is performed using transvaginal ultrasound.	Fertilization of the oocytes

The retrieved ova are fertilized on culture dishes by adding a sufficient number of sperm. The fertilized eggs are normally cultured for 48 hours. By this stage, the fertilized oocytes will have been divided into the 2-4-cell stage. One or two of the best embryos are selected for the transfer, and if there are several good-quality embryos, the rest can be frozen for later use. Embryo transfer is a procedure where the embryos are introduced into the uterine cavity with a soft thin plastic catheter.	Fertilizited oocyte
