Abstract

In the present study, all superovulatory response variables in poor donors were significantly lower than in good donors. Plasma progesterone concentrations at the time of uterine flushing in all heifers were positively correlated with the total number of oocytes and embryos recovered per collection. In good donors, the slope of the regression line for plasma progesterone concentration with total number of of ova and embryos elevates from the time of flushing upto day 10 after flushing and declines gradually, whereas, in poor donors, the slope of regression line shows a decline on day 3 from day 0 and rises afterwards till day 17. The results of the present study indicate that poor embryo donors develop abnormal luteal function following embryo collection.
