Five hundred ninety-one oocytes were laparoscopically recovered in 93 consecutive stimulated cycles. Fifty-three of the 591 oocytes were collected from the cul-de-sac in 39 cycles. The cul-de-sac-originated oocytes had fertilization and cleavage rates of 72 and 79%, respectively; these rates were similar to those achieved in oocytes originating from follicles. A significant decrease in the fertilization rate of cul-de-sac-originated oocytes was noticed in oocytes collected from the cul-de-sac 60 minutes or more after the beginning of the procedure. Oocytes collected from the cul-de-sac yielded 21% of the embryos transferred in cycles where some of the oocytes were recovered from the cul-de-sac. These findings indicate that repeated aspirations of the cul-de-sac may increase the number of embryos transferred.
在连续93个促排卵周期中，通过腹腔镜回收了591个卵母细胞。在39个周期中，从直肠子宫陷凹收集了591个卵母细胞中的53个。源自直肠子宫陷凹的卵母细胞的受精率和分裂率分别为72%和79%；这些比率与源自卵泡的卵母细胞所达到的比率相似。在手术开始60分钟或更长时间后从直肠子宫陷凹收集的卵母细胞中，发现源自直肠子宫陷凹的卵母细胞的受精率显著下降。在一些卵母细胞从直肠子宫陷凹回收的周期中，从直肠子宫陷凹收集的卵母细胞产生了21%的移植胚胎。这些发现表明，反复抽吸直肠子宫陷凹可能会增加移植胚胎的数量。
