Moderate exercise 'better for sperm' than high intensity exercise

ConclusionThis randomised controlled trial indicated doing exercise three times a week may increase sperm quality and count. It showed that undertaking moderate-intensity continuous training was more beneficial than high-intensity continuous training or high-intensity interval training.All three types of training were more beneficial than no exercise.The study was well designed and accounted for confounding variables where possible. However, there are some limiting factors to consider: One of the reasons for the benefit may be due to losing excess weight – all three training programmes were found to reduce BMI and fat, therefore it may be the lower weight contributing to the sperm quality rather than exercise itself. The study was carried out in Iran where there may be diet, cultural and lifestyle factors that might affect sperm quality that are not applicable to populations in other countries. The participants all had a history of doing little exercise. This means they may have been less fit and healthy in the first place compared with the general population of 25-40 year old men. Overall, the study indicates that moderate exercise is conducive to improved sperm quality. However, the exact optimal amount and duration of exercise is unknown, with some research suggesting that participation in very intense competitive sports can lower sperm quality.Read more advice about improving your fertility and what to do if you or your partner are concerned about your fertil...
