BTG3 and Infertility: Some experiments determined that autoantibodies such as APL, ANA, antitissue antibodies, thyroid autoimmunity, anti-ovarian antibodies, and other antibodies have a tendency of increasing the rate of infertility (Wilson et al., 1975; Hoek et al., 1997; Reimand et al., 2001; Shoenfeld et al., 2006; Abalovich et al., 2007), and APL, ANA, and anti-ovarian antibodies were noted as having a correlation with a low rate of implantation and pregnancy (Table 2; Kaider et al., 1999; Ying et al., 2012; Zhong et al., 2012).
