Clinical Trial Summary

The present study aims to evaluate whether the use of a "dual trigger" can improve IVF outcomes, compared to GnRH agonist (GnRH-a) alone, in patients at high risk of OHSS undergoing a freeze-all cycle. By examining freeze-all cycles with frozen embryo transfer(s) (FET) only, we eliminate the potential confounding issue of inadequate luteal support to the endometrium and focus primarily on the effect of a "dual trigger" on oocyte quality and embryo potential.

To our best knowledge, there have been no randomized, controlled trials conducted to address this hypothesis.

Description:

While the use of GnRH-a trigger has nearly eliminated the risk of OHSS, several studies have shown that this strategy may be associated with poorer IVF outcomes after a fresh embryo transfer (Engmann et al., 2008; Galindo et al., 2009; Melo et al., 2017; Sismanoglu et al., 2009; Youssef et al., 2014). These findings may be partly explained by an inadequate LH surge, following a GnRH-a trigger, and raises two separate concerns. The first concern is whether an inadequate LH surge can have an detrimental effect on luteal support following a fresh embryo transfer. The corpus luteum requires constant LH stimulation, during implantation and early gestation, in order to optimize endometrial receptivity via the production of progesterone. The second concern is whether a suboptimal LH surge can reduce the number or quality of mature oocytes retrieved during a treatment cycle. Immature oocytes will not fertilize invitro and, therefore, can decrease a woman's overall success rate with IVF. Based on this second premise, another strategy was developed whereby a "dual trigger", using a combination of a GnRH-a and a lower dose of hCG (1,500 IU), is used to help maximize the number of "mature eggs" retrieved during an IVF cycle without increasing the risk of OHSS. Two recent retrospective studies have evaluated the administration of a "dual trigger" with GnRH agonist in combination with low-dose hCG (1,000 IU), compared to GnRH agonist alone (O'Neill et al., 2016; Griffin et al., 2012). Both studies revealed a significant improvement in the number of mature oocytes retrieved between treatment and controls (Griffin et al., 2012). While these findings are promising, it is important to note that oocyte maturity does not equate to embryo potential. Therefore, whether the use of a "dual trigger" improves embryo development and competency, thus increasing a patient's success rate, remains to be determined.
