Infertility affects 15% of couples in fertile age. Male factor is a cause of infertility in almost half of cases, mainly due to oligoasthenoteratozoospermia (OAT).
A study published by the Archives of Italian Urology and Andrology reviewed the effects of nutritional supplements as a medical treatment for idiopathic male infertility. Use of vitamin E, vitamin A, vitamin C, zinc, etc. supplement were evaluated.
There are rising evidences from published randomized trials and systematic review suggesting that nutritional supplementation may improve semen parameters and the likelihood of pregnancy in men affected by OAT. This improvement, however, is not consistent and there is a wide variation in the treatment regimens used. Well designed and adequately powered RCTs are needed to better clarify the role of nutritional supplements as treatment for male infertility.
