There were statistically significant differences in AngII receptors in individual conditions: NOF showed a correlation between AT1 and AT2 receptors and a negative correlation between AT1 receptor expression, embryo fragmentation and number of metaphase II (MII) oocytes; PR showed a negative correlation between AT2 receptor expression and number of MII oocytes; PCOS AT1 receptor expression correlated negatively with the units of FSH administered and with patients' age; ENDO showed no significant correlations.
