No results posted yet for this study

Summary

The researchers hypothesize that emergency contraception (EC) will initiate the changes associated with atresia or ovulatory failure at all stages of follicular development and that the image attributes associated with atresia will be similar regardless of the diameter of the dominant follicle when ovarian suppression is initiated. Second, changes associated with atresia may be observed, but ovulation of the dominant follicle is unimpeded.
