“…After review of the titles and abstracts, 41 studies were identified as potentially eligible for inclusion. After full review, four systematic reviews were excluded (Levine et al, 2015;Lopategui et al, 2017;van Dorp et al, 2016;Burkart et al, 2019), one publication because data could not be extracted (Zynda et al, 2012), 15 original studies because of the absence of a healthy control group (Carter et al, 2006;Kiserud et al, 2007;Sudour et al, 2010;Speiser et al, 2011;Hamre et al, 2012;Hansen et al, 2013;Reinmuth et al, 2013;Shepherd et al, 2006;Greaves et al, 2014;Naessén et al, 2014;Hoshi et al, 2015;Wu et al, 2015;Yonemoto et al, 2016;Shandley et al, 2017;Nichols et al, 2018) and three additional studies because they generically referred to reproductive prognosis after cancer without splitting data for cancer subtypes (Green et al, 2009;Reulen et al, 2009;Dillon et al, 2013).…”
