Luo L, Chen M, Wen Y, et al. - Via performing an open‐label, randomized, controlled trial, researchers sought to compare the live birth rate and cost effectiveness of artificial cycle‐prepared frozen embryo transfer (AC‐FET) with or without GnRH agonist (GnRH‐a) pretreatment for women with polycystic ovary syndrome (PCOS). Among the sample of 343 women with PCOS (aged 24–40 years) who were scheduled for AC‐FET and receiving no more than two blastocysts, 172 formed the pretreatment group and received GnRH‐a pretreatment; and 171 formed the control group and did not receive GnRH. Outcomes suggest that pretreatment with GnRH‐a is not correlated with improvement in pregnancy outcomes but with a significant rise in patient cost among women with PCOS receiving AC‐FET.
