“…The other two (Al-Inany et al, 2016;Gibreel et al, 2012) included studies comparing mild ovarian stimulation versus standard IVF. Gibreel et al (2012) compared clomiphene citrate with gonadotrophins (with or without GnRH antagonist) versus gonadotrophins with GnRH agonist protocols; the search was updated in February 2015 to yield a total of seven RCTs applicable to our clinical question (Fenichel et al, 1988;Grochowski et al, 1999;Harrison et al, 1994;Karimzadeh et al, 2010;Long et al, 1995;Revelli et al, 2014;Zhang et al, 2014). Al-Inany et al (2016) compared GnRH antagonist versus long agonist protocols; the search was updated in June 2015 to yield a total of nine RCTs relevant to our clinical question.…”
