Which nutritional supplements are recommended for treating male infertility?

While there is increasing evidence that nutritional supplements tabletki na powiększenie penisa improve particular semen parameters in particular groups of men, the evidence is derived mostly from small trials. Typically evidence from large trials, involving for example hundreds or thousands of participants, is needed before particular interventions (in this case, provision of nutritional supplements) can be recommended as treatment for health conditions (such as male factor infertility). Therefore, more research, involving greater numbers of men is needed to determine whether or not nutritional supplements improve semen quality before they can be recommended as a treatment for male factor infertility. It is also important to note that most evidence to date details associations between increased micronutrient intake and improved semen parameters, but not improved fertility (for example, the time it takes for a couple to conceive or the risk of miscarriage after conception). While improved semen quality should theoretically improve male fertility, there is to date no direct evidence that the semen quality improvements associated with increased micronutrient intake also improve fertility. Studies which investigate whether or not nutritional supplements improve time to pregnancy and other indicators of fertility are also needed. Currently there remains insufficient evidence on the effect of nutritional supplements on the fertility of human males to recommend them as therapy for male factor infertility. However, we do know from strong clinical evidence that a healthy diet (e.g. low in fat and containing plenty of fruit and vegetables) and lifestyle (with plenty of exercise), which protects against the development of obesity, diabetes and other chronic health conditions protects sperm health. Men who are concerned whether their nutritional intake is affecting their sperm health should therefore filmy pornograficzne focus on improving their diet and getting regular exercise, rather than taking nutritional supplements.
