Isolated teratozoospermia : is there a role for antioxidant therapy?

Recently, literature has emerged that offers contradictory findings of idiopathic forms of isolated teratozoospermia that may confuse clinicians. Some researchers argue that at 0-1% of normal forms of spermatozoa, morphology itself cannot be a prognostic indicator of fertility, either in the planning of natural pregnancy, or when used in assisted reproduction. In this connection, the possible causes of teratozoospermia and alternative therapies are being actively sought, in addition to known invasive and costly procedures. There is convincing evidence that reactive oxygen species overproduction is associated with the occurrence of abnormal spermatozoa in the ejaculate. An abnormal morphology can be accompanied by damage to the sperm DNA, impaired chromatin condensation, and associated unsuccessful pregnancy outcomes. Most of the studies show that using antioxidants results in positive changes. This literature review highlights the role of oxidative stress and DNA fragmentation in the formation of morphologically abnormal spermatozoa. The authors discuss drug interventions to treat teratozoospermia and present their own recommendations for antioxidant therapy in the clinical management of idiopathic forms of male infertility.
