In order to assess whether electro-acupuncture (EA) can reduce a high uterine artery blood flow inpedance, 10 infertile but otherwise healthy women with a pulsatility index (PI) =3.0 in the uterine arteries were treated with EA in a prospective, non-randomized study. Before inclusion in the study and throughout the entire study period, the women were down-regulated with a gonadotrophin-releasing hormone analogue (GnRHa) in order to exclude any fluctuating endogenous hormone effects on the PI. The baseline PI was measured when the serum oestradiol was =0.1 nmol/l, and thereafter the women were given EA eight times, twice a week for 4 weeks. The PI was measured again closely after the eighth EA treatment, and once more 10-14 days after the EA period. Skin temperature on the forehead (STFH) and in the lumbosacral area (STLS) was measured during the flrst, fifth and eighth EA treatments. Compared to the mean baseline PI, the mean PI was significantly reduced both shortly after the eighth EA treatment (P < 0.0001) and 10-14 days after the EA period (P < 0.0001). STFH increased significantly during the EA treatments. It is suggested that both ot these effects are due to a central inhibition of the sympathetic activity.

Results Blood flow impedance Compared to the mean baseline PI, the mean PI was significantly reduced both soon after the eighth EA treatment (P < 0.0001) and 10-14 days after the EA period (P < 0.0001) (Figure 1), at which time six women had a mean PI <2.6 (Table II and Figure 2).
