A correlation of the uterine and ovarian blood flows with parity of nonpregnant women having a history of recurrent spontaneous abortions.

The aim of this prospective study was to explore the relationship between the incidence of recurrent spontaneous abortions (RSA) and values of Doppler indices characterizing the uterine and ovarian flows in nonpregnant women with a history of primary and secondary RSA using color, power and pulsed Doppler transvaginal ultrasonography. A total of 19 healthy women as a control group A and 81 women with a history of RSA as a study group B were examined on the 21st day of a regular menstrual cycle. Our study demonstrated the presence of significantly decreased uterine and ovarian blood flows in women with primary and secondary RSA if more than 3 abortions had occurred. The obtained values were less favorable in the primary RSA compared with the secondary RSA cases.
