Eggs that are grown with drug treatments that start on the 2nd day of menstruation are collected from the ovaries with a special device under anesthesia in the operating room environment. The collected eggs are first placed in special culture solutions, then kept in incubators containing 6% CO2 at 37 degrees for 3-5 hours. During this process, the sperm sample taken from the man is washed and prepared. The eggs are fertilized with sperm using a microinjection technique with the help of a special microscope. After 14-16 hours, the cells around the eggs are cleaned and fertilization is checked. The patient does not feel any pain during this procedure
