However, further detailed and extensive research is still required to determine the dosage and the usefulness of lycopene as a treatment for male infertility. Hum Fertil Cambridge, England 16 3 — The lack of an effective placebo control group in each of these studies limits their interpretation and generalisability and highlights the need for a randomized placebo control trial. Oxidative stress is believed to play a role in the pathogenesis of idiopathic male infertility and although reactive oxygen species play an important role in normal sperm function, disequilibrium of reactive oxygen species and antioxidant defence appears to be detrimental [ 37 ]. Nevertheless, this paper did provide an indication of the likely sample size required, and on this basis, we aimed to recruit 30 participants per treatment arm.
