Abstract
Cancer has been affecting a growing number of children, adolescents and adult males in reproductive age. Male reproductive potential is adversely affected by chemotherapeutic drugs and patients are at risk for prolonged infertility. Fertility recovery is related to the chemotherapeutic agent and dosage used, being thus difficult to predict. As a result, there is a strong need to identify a natural or synthetic compound that is able to preserve male fertility without interfering with the efficacy of the chemotherapeutic regimen. New procedures, as well as several drugs, are being investigated to assess their efficiency in protecting male reproductive functions from the chemotherapy side-effects. This review provides an overview of the wide range of chemotherapeutic drugs regularly used in cancer treatment and their detrimental effects on male fertility. In addition, it also assesses the existing protector agents for male fertility and their usefulness in preserving and protecting male reproductive functions exposed to chemotherapeutics. Several protector agents for male fertility are being studied, and results are promising. Nonetheless, further research must be implemented to identify a supplemental therapy that addresses the multiple side effects of chemotherapy on male reproductive function. Until such therapy is discovered, it is fundamental that all fertility preservation options are discussed with patients, before treatment is initiated, to assure parenthood.
