When follicles that have reached a certain size (structures containing fluid-filled eggs observed on ultrasound) are obtained with ovarian stimulation, a cracking needle (hCG; Profasi; Pregnyl or Ovidrel) is applied and egg collection is performed 36 hours later.
Today, egg retrieval is always performed with vaginal ultrasonography. While the patient is lying in the gynecological examination position, he is covered with sterile covers, and vaginal local area cleaning is applied after speculum application. We perform the egg retrieval procedure under light general anesthesia in our clinic. Then, vaginal ultrasonography is started. The ovaries are reached with a needle passed through the guide on the vaginal ultrasonography. Each follicle is entered one by one and its contents are emptied into a heated sterile tube with the help of a special aspirator. The contents of the tube are immediately passed to the laboratory and examined under a microscope whether it contains eggs. Sometimes, if the egg cannot be obtained in the first pull (aspiration) from the follicle, the inside of the follicle is washed with a special liquid and the remaining egg is tried to be removed. In this way, it is tried to collect eggs from the whole follicular.
Egg collection takes about 15-20 minutes. After an hour of rest, the patient can go home.
