Oocyte retrieval in an in vitro fertilization-embryo transfer program: comparison of four methods.

Abstract

The records of 191 patients involved in 316 treatment cycles over 3 years in an in vitro fertilization-embryo transfer program were reviewed. Follicular aspiration, oocyte retrieval, pregnancy rates, technical difficulty, and complications were compared in four oocyte retrieval methods: 117 laparoscopic retrievals, 116 ultrasound (US)-guided percutaneous transvesical retrievals, 43 US-guided transvaginal retrievals, and 40 combined US and laparoscopic retrievals. The mean number of aspirated follicles (9.14) was greatest in the transvaginal retrieval group, but the ratio of oocytes to punctured follicles was not statistically greater in any of the groups. The overall clinical pregnancy rate per cycle was highest in the transvaginal retrieval group: 12 of 43 cycles resulted in pregnancy, or 27.9%. The number of delivered babies (16.3%) was also highest in the transvaginal retrieval group. US-guided transvaginal oocyte retrieval is recommended as the method of choice.

Laparoscopically‐assisted transabdominal oocyte retrieval in an infertility patient with ovarian malposition

“…Her uterus showed bicornuate uterus and her fallopian tube was elongated Fig. 2 Results of the patient's pelvic MRI, which confirms the position and location, in the upper pelvic cavity, of the bilateral ovaries which were attached to the area above the common iliac vessels ultrasound-guided technique with that using the laparoscopic technique, and reported that the former outperformed the latter [2]. Recently, however, some cases of patients with ovarian malposition who underwent ultrasound-guided transabdominal oocyte retrieval have been reported [3,4].…”

Is there a benefit in follicular flushing in assisted reproductive technology?

“…Laparoscopy was soon replaced by transvaginal retrieval under ultrasound guidance as the primary route to obtain oocytes for assisted reproductive technologies (ART) due to its safety, effectiveness, and the avoidance of general anesthesia [3][4][5][6]. The conversion to a transvaginal retrieval approach was followed by refinements in the oocyte retrieval needle design in an effort to maximize recovery and minimize patient discomfort [7][8][9].…”

Retrieval of rhesus monkey (Macaca mulatta) oocytes by ultrasound‐guided needle aspiration: Problems and solutions

“…However, the laparoscopic method is a tedious and time-consuming procedure due to the complicated experimental setup (Flood et al, 1989;Bavister, 2004). Furthermore, laparoscopic oocyte retrieval is only possible when the ovarian cortex is partly exposed and follicles are visible under the surface (Wiseman et al, 1989). The ultrasound-guided follicle aspiration procedure represents a better alternative to the other two methods in terms of reduced invasiveness, infection risk and other potential detrimental effects, work involved, and post-operative recovery (Seifer et al, 1988;Flood et al, 1989;Wiseman et al, 1989).…”
