PURPOSE: To determine the haemodynamic parameters in women with tubal and male factors of infertility and to investigate the effect of ovarian stimulation on the blood flow indices of the uterine and ovarian arteries.
METHODS: Prospective evaluation of the pulsitility index (PI) and resistance index (RI) of the uterine and ovarian arteries in the tubal and male factors of infertility was done. Comparisons were made between the natural and ovarian stimulation cycles.
RESULTS: In natural cycles, uterine PI was 3.55 +/- 1.39 and RI was 0.95 +/- 0.05 in tubal infertility. These were significantly lower (uterine PI = 4.13 +/- 0.08; uterine RI = 0.99 +/- 0.06) than the corresponding indices in patients with male factor infertility. After ovarian stimulation in tubal factor, uterine PI and RI were 2.62 +/- 0.73 and 0.88 +/- 0.08 and were similar (PI = 2.55 +/- 0.62, RI = 0.87 +/- 0.06) to male factor infertility.
CONCLUSIONS: The data points to measurable differences in the uterine PI and RI between the tubal infertility and male infertility in the natural cycles. These differences were abolished after ovarian stimulation.
