Objective To determine whether the p53 codon 72 single nucleotide polymorphism, a change of the amino acid arginine (Arg) to proline (Pro) resulting from a single nucleotide mutation of guanine (G) to cytosine (C), has a clinically significant effect on implantation rate in fresh IVF cycles. Design Prospective cohort analysis. Setting University-affiliated private IVF center. Patient(s) One thousand fifty-six female patients undergoing fresh nondonor IVF cycles. Main Outcome Measure(s) Embryo implantation rate. Result(s) Of the 1,056 patients (2,600 total embryos transferred) undergoing their first IVF cycle, 289 had no implantation events and attempted a second cycle. Of the 289 patients in their second cycle, 72 had no implantation events and attempted a third cycle. The p53 codon 72 single nucleotide polymorphism frequencies in the first cycle (homozygous major allele Arg/Arg [G_G] = 45%, heterozygous allele Arg/Pro [G_C] = 44%, and homozygous minor allele Pro/Pro [C_C] = 11%) did not differ significantly across subsequent IVF cycles. There was no statistically significant difference in embryo implantation rate with respect to the single nucleotide polymorphism. Conclusion(s) The p53 codon 72 single nucleotide polymorphism lacks a clinically significant effect on embryo implantation rate in patients undergoing fresh nondonor IVF cycles.
