Comment on Increase of success rate for women undergoing embryo transfer by transcutaneous electrical acupoint stimulation: a prospective randomized placebo-controlled study

30 12 2011

To the Editor:

It is widely known that embryo quality affects pregnancy and live birth rates. Nevertheless, in their article, “Increase of success rate for women undergoing embryo transfer by transcutaneous electrical acupoint stimulation: a prospective randomized placebo-controlled study,” Zhang et al. do not mention the quality of transferred embryos at all (1). In addition, there is no information about ovarian stimulation protocols (GnRH agonist? GnRH antagonist? Recombinant or urinary FSH?), length of stimulation, endometrial thickness or day of embryo transfer. One might expect day-5 cycles to be different, for better or worse, considering that the interval between intervention [transcutaneous electrical acupoint stimulation (TEAS)] and embryo implantation would have been shorter.
