How Does Ovum Growth Follow-Up Take Place in IVF Treatment?
Both begin with oocyte growth treatment. It is tried to obtain about 5-10 oocytes from every woman by using egg-growing drugs. The number of oocyte is as important as the age of women in determining pregnancy chance.
Drugs used for this purpose are in the form of injection and are usually administered subcutaneously. Roughly it is required to be administered at the same time every day. It is usually initiated on the 2nd or 3rd day,although there are different drug schemes. 5-6 days later, 2nd control is performed. The sizes of oocytes are measured during this control. According to the situation, the drug dose adjustment is made. The next controls are every 2-3 days.
As the oocytes reach medium size, this time another injection preventing early cleavage begins to be used on a daily basis. Because a cleaved oocyte without complete maturation will not be useful.
When the oocytes that grow in this way for a few days reach to a size of 17-20 mm, the egg cracking shot is administered. The purpose here is not to cleave the oocyte. Because it will not be possible to collect the cracked and dispersed oocytes in the uterus.
