The Effectiveness and Safety of Transabdominal Oocyte Pick up Using a Vaginal Ultrasound Probe in Patients with Endometrioma Undergoing Oocyte Cryopreservation

Objective: To assess whether transabdominal oocyte pick up is safe and effective in single patients with endometrioma undergoing IVF for the purpose of oocyte cryopreservation.Materials and Methods: In this retrospective cohort study 13 virgin patients with endometrioma who underwent transabdominal oocyte pick-up for the purpose of oocyte cryopreservation was analyzed.Demographic characteristics, and hormonal assessment including AMH, day 3 serum FSH, LH, estradiol and progesterone levels, and antral follicle counts were recorded.Primary outcome measures were number of oocytes retrieved, metaphase 2 oocytes frozen, follicle oocyte index, and complication rates, while secondary outcome measures were duration of stimulation, cumulative gonadotropin dose, and duration of the procedure.Results: The mean age of patients was 32,78,5.The mean diameter of the endometrioma was 48,123,6 mm, antral follicle count was 6,022,92, serum AMH was 0.620.32ng/ml, and day 3 serum FSH and estradiol were 9,32,4 IU/ml and 60,028,6 pg/ml respectively.The mean duration of stimulation was 8,51,98 days, cumulative gonadotropin consumption was 1659546 units, and duration of the procedure was 8.33.9 min.The mean number of oocytes retrieved was 5,53.1,oocytes frozen was 4,152.23,and mean modified follicle oocyte index was 0,930,17.No major complication occurred in any of the patients; however, one patient was temporarily hospitalized for six hours for severe pelvic pain.Conclusions: Transabdominal oocyte pick up is safe and effective procedure in single patients with endometrioma undergoing IVF for the purpose of oocyte cryopreservation.
