To study H19 ICR methylation levels in association with sperm 47 parameters routinely analyzed in idiopathic recurrent spontaneous miscarriage cases.
Academic research setting.
Male partners of couples with a history of idiopathic Recurrent Spontaneous Miscarriage (RSM group) and Male partners of couples with proven fertility (control group).
Main Outcome Measure(s):
Paternal age, sperm concentration, motility, chromatin compaction status, morphology, and H19 ICR methylation were assessed in control and idiopathic RSM group participants
Paternal age and basic semen parameters analyzed did not show any significant difference between the two groups; however H19 ICR methylation levels were reduced significantly at (p<0.01) in the idiopathic RSM group compared with the control group. Conclusion(s):
Significant reduction in the H19 ICR methylation without significant difference in the sperm parameters demonstrates aberrant imprinting to be associated with idiopathic RSM.
