Transvaginal follicel aspiration guided by transvaginal ultrasound for ova recovery is rapidly gaining popularity in many centers practicing in vitro fertilization and embryo transfer (IVF-ET). Cycle outcome following this new method has not been directly compared to the traditional, laparoscopic recovery technique. To this end, the authors evaluated multiple parameters in 66 laparoscopic (group A), and 44 transvaginal ova recovery procedures (group B) in patients undergoing IVF-ET. No statistically significant differences could be demonstrated between the groups in all but the rate of ova fertilization. The rate of fertilization was higher in the ova recovered by transvaginal follicle aspiration (59.6 versus 69.2%; P < 0.01). No difference could be demonstrated between the groups in the other parameters examined, which included the number of ova recovered (5.7 ± 0.4 versus 6.0 ± 0.7), ova maturity (87 versus 84% intermediate ova), rate of polyspermic fertilization (3.9 versus 5%), rate of cleavage (88 versus 91%), cleavage stage at transfer (37.8 ± 0.8 versus 3.5 ± 0.4 cells per embryo), number of embryos transferred per patient (2.7 ± 0.1 versus 3.3 ± 0.2), and pregnancy rates. The potential detrimental effects of general anesthesia and CO2 pneumoperitoneum present during laparoscopy but not ultrasound guided recovery on ova quality may underlie the observed difference in fertilization between the groups.
