Graafian follicle growth and development and Doppler flow analysis of blood vessels in the wall of the follicle, was analyzed. Twelve patients with primary infertility were observed between days 12 to 15 of the cycle. Analysis of resistance index (RI) and pulsatility index (PI) of the wall vessels was performed. Statistically significant difference in RI and PI indices in preovulatory and post-ovulatory period was observed.
