No doubt, RPO should be considered as one of the healthy and nutritional oils. However, there are inconsistent and controversial reports on its role in amelioration of obesity and by extension, male infertility prevention. Therefore, further studies to investigate the effect of RPO on the renal, hepatic, and cardiac functions as well as spermatogenesis in dietary-induced obese male Wistar rats are hereby proposed. Besides, human volunteers can be recruited for a longitudinal testing on the effect of the oil consumption over a period of 6–12 weeks.
