Abstract

To gain insight into the physiological significance of basal ovarian stromal blood flow and to assess whether its detection ability is related to ovarian reserve in infertility patients undergoing in vitro fertilization (IVF)-embryo transfer (ET) treatment. Thirty two consecutive infertile women scheduled for IVF-ET treatment were prospectively evaluated. Basal ovarian hormonal, ovarian volume and stromal blood flow studies were performed on day 3 of a natural cycle before treatment. The performer of the ultrasound studies was blinded to the clinical data. Women in the study were divided into two groups in accordance with estradiol level on the day of administration of human chorionic gonadotropin. Day-3 follicle-stimulating hormone and ovarian volume were significantly poorer in the women with low (group A) as compared with good (group B) ovarian reserve. Likewise, the numbers of follicles ≥14 mm in diameter, oocytes retrieved and embryos achieved were significantly lower in group A than group B. Six clinical pregnancies were obtained in group B, whereas no pregnancy was obtained in group A. Nine out of the 15 (60%) women in group A had undetectable basal stromal blood flow in at least one of the ovaries, whereas only one of the 17 (6%) women in group B had undetectable flow (p < 0.002). Basal stromal peak systolic blood flow velocity, pulsatility index and resistance index mean values did not differ significantly between the two groups. We conclude that undetectable basal ovarian stromal blood flow in at least one ovary is related to low ovarian reserve in infertile women undergoing IVF-ET. It seems that undetectable basal stromal blood flow is not solely a technical issue, but rather linked to the pathophysiology of ovarian aging.
