“…The current results support previous reports that demonstrated a strong association between the longer AR‐CAG repeats and the oligozoospermia and teratozoospermia (Badran et al., 2009; Batiha et al., 2018; Dowsing et al., 1999; Fesai et al., 2009; Grigorova et al., 2017; Hadjkacem et al., 2004; Han et al., 2013; Khatami et al., 2015; Kukuvitis et al., 2002; Mostafa et al., 2012; Zare‐Karizi, Amin‐Beidokhti, Rahimi, & Mirfakhraie, 2016), as well as the lack of association between azoospermia and CAG repeats in the AR gene (Batiha et al., 2018). On the other hand, some studies reported a significant correlation between AR‐CAG repeat length and azoospermia in Australia, Greece, USA, Singapore, Ukraine, Iran and Baltic (Dowsing et al., 1999; Fesai et al., 2009; Grigorova et al., 2017; Kukuvitis et al., 2002; Mifsud et al., 2001; Zare‐Karizi et al., 2016). Interestingly, a Japanese study indicated an association between the reduced CAG repeats length (14 and 15 repeats) and impaired spermatogenesis in infertile men (Komori et al., 1999).…”
