[Changes of the pulsatile index in ovarian and uterine arteries of infertile women. Case-control study].

BACKGROUND: This study was performed to evaluate the frequency of female pathology that cause infertility and to appraise the difference of pulsatility index in the ovarian and uterine arteries in infertile women and in a control group of healthy women. METHODS: In the period between January 1997 and March 1999 52 infertile couples were examined carrying out an accuracy anamnesis and objective examination. The dosing of FSH, LH, estrogens, progesterone, and an ultrasound examination for each woman was required. The pulsatility index in the ovarian and uterine vases was calculated with the color Doppler technique. RESULTS: A female pathology caused infertility in 24 couples, where only in nine couples the cause was masculine. In 14 couples there was a pathology in both the partners. In 5 couples any pathology was identified. The median of pulsatility index in healthy women was 1.8. Variations were observed in all the women with ovarian or uterine pathology unless in those with uterine malformations. An increase of the pulsatility index was observed also in 3 couples in which any cause of infertility was identified. CONCLUSIONS: Female pathology is a very common cause of infertility. The evaluation of the pulsatility index in ovarian and uterine arteries can be useful diagnosing the cause of infertility and in to explain an infertility due to unknown cause.
