In Vitro Fertilization
For Whom Is IVF Treatment Suitable?
The fertilization is expected to occur spontaneously by putting the oocytes retrieved from the woman and the sperms retrieved from the man together. Contrary to what is believed, the fertilization process takes place in small plastic plates called dish, not inside the tube. These plates are kept in a device called an incubator, mimicking the mother’s uterus.
The temperature, humidity and carbon dioxide ratios are stable in these devices. In in vitro fertilization technique, one of the sperms floating around the oocyte is desired to penetrate the oocyte shell and fertilize the oocyte. After the first sperm enters, the oocyte does not allow any other sperm entry since it changes its shell structure.
The next day, fertilization control is done and the family is informed about how many oocytes are fertilized. Fertilization rates are more related to the capacity of the sperm rather than eggs. Since fertilization cannot occur if there is a motility, number or deformity disorder in the sperm, in vitro fertilization cannot be performed with this type of sperm. Microinjection procedure would be more appropriate.
