title: Total ovarian volume before human chorionic gonadotrophin administration for ovulation induction may predict the hyperstimulation syndrome.
abstract: Total ovarian volumes were measured before the administration of HCG in 42 women undergoing treatment for infertility by in-vitro fertilization (IVF) and embryo transfer and considered to have an exaggerated response to stimulation ( > 20 follicles). Seven women who subsequently developed moderate or severe ovarian hyperstimulation syndrome (OHSS) (n = 7; group 1) were compared with 35 matched controls (five matched controls per case; n = 35; group 2) of similar age, number of follicles and duration of infertility who underwent follicular stimulation, oocyte recovery, in-vitro fertilization and embryo transfer during the same period but did not develop moderate or severe OHSS. The mean age, duration of infertility and total number of follicles were similar but the mean total ovarian volume was significantly higher in the group of women who developed moderate or severe OHSS compared with controls (271.00 +/- 87.00 versus 157.30 +/- 54.20 ml; P < 0.01). We conclude that total ovarian volume measured before HCG administration is higher in women who develop moderate or severe OHSS compared with controls and may therefore be used as an additional parameter in the preventative strategy for the ovarian hyperstimulation syndrome.
