Objectives:
To investigate the complications of the oocyte retrieval procedure currently used in in vitro fertilisation.
Material And Methods:
We examined 1.031 patients who underwent oocyte retrieval in the IVF unit of our hospital for complications developed during and after the procedure.
Results:
No complications developed related to sedation or general anaesthesia. Vaginal bleeding was observed in 3.1% of the patients. There was no intra-abdominal bleeding or pelvic organ injuries requiring surgery. Two patients developed pelvic abscesses. Ovarian hyperstimulation syndrome (OHSS) occurred in 1.45% of the patients. Almost all of the patients tolerated the oocyte retrieval process well. After the procedure, only 2% of the patients described their pain as severe, and 0.4% as the worst pain they had ever experienced.
Conclusions:
The most common complication during oocyte retrieval is vaginal bleeding, which is largely controlled by buffer application. In conclusion, the oocyte retrieval process can be considered a safe procedure.
