In vitro fertilization and embryo transfer in patients with one ovary.
The purpose of this investigation was to compare follicular response and pregnancy rates in patients with one and two ovaries who have undergone in vitro fertilization (IVF). No statistically significant difference was found in serum estradiol levels on the day of human chorionic gonadotropin administration, mean number of follicles (greater than 15 mm), mean total number of oocytes recovered, mean number of mature oocytes recovered, or number of pregnancies per transfer. The total number of oocytes recovered in the one- and two-ovary groups was 47 and 123, respectively. There was a significantly greater mean number of immature oocytes recovered (1.5 +/- .03 versus 0.5 +/- 0.2, P less than 0.01) and embryos transferred (2.7 +/- 0.3 versus 1.7 +/- 0.3, P less than .04) in patients with two ovaries. Though not statistically significant, a trend was noted in the two-ovary group for a greater number of pregnancies per transfer (9:25 versus 2:14). The authors conclude that single-ovary patients may have a reduced outcome with IVF compared with patients with two ovaries.
