The successful recovery and fertilization of oocytes from the pouch of Douglas.
Two groups of women were studied in whom a proportion of follicles had either ovulated spontaneously (7 women) or ruptured during manipulation at laparoscopy (30 women), and oocytes were recovered from the pouch of Douglas. There were no significant differences in the fertilization rates of oocytes collected in the pouch of Douglas from ovulated follicles, compared with those from the remaining intact follicles [15/20 (75%) vs 14/20 (70%)]. Also, there was no significant difference between the fertilization rate of oocytes from follicles ruptured at the time of oocyte collection and that of oocytes from intact follicles [25/38 (66%) vs 101/140 (72%)]. One woman became pregnant, following the transfer of four four-cell embryos, all derived from spontaneously ovulated oocytes found in the pouch of Douglas. She gave birth to a baby girl. The present study has shown that oocytes may still be retrieved from the pouch of Douglas, despite follicle dispersal; these oocytes can be fertilized; and the embryos derived from ovulated oocytes recovered from the pouch of Douglas may generate an ongoing pregnancy following in vitro fertilization and embryo transfer.
