Ultrasound-guided, transvaginal egg retrieval is a procedure whereby a long, thin needle is passed through the vagina into the ovary. Although women are under sedation or local anesthesia, this procedure can cause mild to moderate discomfort. Injuries during this procedure are extremely rare. Structures near the ovaries, such as the bladder, bowel, or blood vessels, could possibly be injured and require further surgery. Limited bleeding from the ovary may occur, but the need for transfusion is extremely rare.
Infections following transvaginal egg retrieval are also possible but rare.
Laparoscopic egg retrieval can be complicated by any of the surgical risks associated with laparoscopy. The risk of major injury to the bladder, bowel, uterus, blood vessels, or other pelvic structures occurs in approximately 1 in 500-1,000 surgeries. If injury occurs, further surgery may be required. Infection following laparoscopy rarely occurs. Anesthesia complications are rare in healthy women.
