Materials and Methods: One hundred twelve infertile women undergoing standardized
controlled ovarian hyperstimulation for ICSI- ZIFT entered this randomized clinical
trial. Patients were randomized to equal groups of combined PTX and tocopherol
therapy or none (not receiving PTX and tocopherol). These drugs were administered to
the intervention group for two cycles before starting ICSI-ZIFT cycle. Main outcome
measure was clinical pregnancy rate. SPSS.11 software (SPSS Inc. Chicago IL.) was
used for data collection and analysis.
