Abstract:

Dear Editor,

We read the article by Banker et al. (1) with pleasure because their results support our prior observations (2, 3, 4). We had also compared 2 matched cycles of 59 oocyte donors, 1 with follicular estradiol scheduling (FES) and 1 without (2, 3). Both were flexible gonadotropin-releasing hormone antagonist cycles; however, different from the study by Banker et al. (1), we administered 2 mg of estradiol valerate tablets 3 times a day, from cycle day 2 until commencement of gonadotropins on a scheduled day (1, 2).
