[Ovum-embryo competitiveness determined by the quantification of perifollicular indices in Doppler vascular micro-architecture].

OBJECTIVE: To obtain the linear correlation between Doppler flowmetry rates and follicular development and the observed embryo growth in ovarian hyperstimulation cycles in the IVFTE/ICSI results.

MATERIAL AND METHODS: A prospective and observational study including 29 patients was carried out. The ovarian reserve was determined--by the ovaries morphometric conditions--as well as basal FSH. These were correlated with pulsatility rates (PR), resistance rates (RR), and the systole/diastole ratio (S/D) and the maximum flow rate (TAmax), using a USG pulse-colour Doppler. All these were correlated to embryo development. Covariance, regression lines and confidence intervals analyses were performed for its statistical determination.

RESULTS: A correlation between RR and the formation of mature follicles was observed (p = 0.05), and, at the same time, a negative relationship between FSH and ovarian volume was found.

CONCLUSIONS: A series of markers of ovarian reserve have been described, however, none of these is a specific marker when ovum quality is expressed through the administration of ovulation inducers. Considering the data obtained in our study, we can say that Doppler flowmetry rates can indicate follicular expression and the resulting ovum and embryo development.
