background: the piwi-interacting rna (pirna) pathway has an essential role in transposon silencing, meiosis progression, spermatogenesis, and germline maintenance. hiwi genes are critical for pirna biogenesis and function. therefore, polymorphisms in hiwi genes contribute to spermatogenesis defects and can be considered as risk factors for male infertility. the aim of the present study was to i...
