Does addition of low-dose aspirin and/or steroid as a standard treatment in nonselected intracytoplasmic sperm injection cycles improve in vitro fertilization success? A randomized, prospective, placebo-controlled study.

PurposeTo investigate the effects of short-term low-dose aspirin and/or steroid use on implantation and pregnancy rates in nonselected intracytoplasmic sperm injection (ICSI) cycles.MethodsTwo-hundred patients undergoing ICSI for their first cycle were enrolled in this study. Participants were then randomized into four groups on the embryo transfer day. Aspirin (100 mg/day) in group A, prednisolone (10 mg/day) in group B, aspirin along with prednisolone in group C were given while placebo was administrated to group D.ResultThere were no statistically significant differences recorded in the demographic, ovulation induction cycle characteristics between groups. Mean transferred embryo number and mean top quality embryo number were similar among study groups. There were no statistical differences in implantation and pregnancy rates between study groups.ConclusionAdministration of low-dose aspirin and prednisolone alone or concomitant as a standard treatment have no positive effects on implantation and/or pregnancy rates.
