Expression pattern of PRM2, HSP90 and WNT5A in male partners of couples experiencing idiopathic recurrent miscarriages

  • RIMA DADAEmail author
Research Note


Recurrent pregnancy loss affects approximately 3–5% of couples attempting to have a child. It is defined as the occurrence of two or more consecutive pregnancy failures before 20 weeks of gestation. In about 40% of cases, the cause remains unknown and are defined as idiopathic recurrent miscarriages (iRM) (Stephenson and Kutteh 2007). However, most of these diagnostics tests are performed in the female partner, with the male’s contribution remaining relatively underexplored (only paternal karyotyping is done). Paternal factor may be the underlying aetiology in RM (Lalancette et al.2008) and molecular abnormalities in sperm may have an adverse effect on embryonic development. Certain portion of sperm genome remains transcriptionally active and codes for transcripts which are of paramount developmental importance (Krawetz 2005; Gil-Villa et al.2010). Among these, the role of long-lived sperm RNA which are not translated is controversial. Sperm possess a remarkable set of...
