Before initiation of the run- in phase of the study, two 40- sets of random numbers will be created by a member of the research team not involved in recruitment. 15 blocks with size of 4 and combination of A for the carob and B for vitamin E group will be prepared. Allocation sequence will be password-protected and only accessible to the reproductive health researcher. She folds the paper containing 4-size blocks, put them in the standard thick envelopes and write the serial numbers on them. All of the envelope will be kept at the recruitment center. Thus, for every eligible patient, the researcher randomly selects one of the envelopes after assign subjects into intervention and comparison group, Blinding description: outcome assessor and data analyser will be blinded to group assignment for the exploratory outcomes of treatment, treatment completion and treatment response which will be assessed by medical staff not otherwise involved in the study. 3 Male infertility.
