Testicular cancer is considered a rare disease affecting approximately 1% to 2% of the male population. This neoplasm has a cure rate of over 95%; as a result, a major concern is the future of fertility of carriers from this disease. There are several histological subtypes of testicular tumors; however, the Testicular Germ Cell Tumors (TGCTs), comprising both seminoma and non-seminoma tumors, are considered the main subtypes of testicular neoplasms. TGCT are characterized by being a solid tumor

... that mostly affects young men aged between 15 and 40 years old. While TGCT subtypes may have an invasive potential, seminoma subtype does not affect other cells rather than germ cells, while non-seminomas have more invasive properties and can achieve somatic cells; thus, having a more aggressive nature. This research intends to review the literature regarding information about sperm parameters, correlating the data found in those studies to the subfertility and infertility of patients with TCGTs. Furthermore, it will also correlate the data to the non-seminoma and seminoma histological subtypes from pre-and post-cancer therapy. PubMed databases were used. Searched keywords included: seminoma AND non-seminoma; male infertility; germ cell tumor; chemotherapy AND radiotherapy. Only articles published in English were considered. Current studies demonstrate that both TGCT subtypes promote deleterious effects on semen quality resulting in decreased sperm concentration, declined sperm total motility and an increase in the morphology alterations. However, findings suggest that the non-seminoma subtype effects are more pronounced and deleterious. More studies will be necessary to clarify the behavior of seminoma and non-seminoma tumors implicating the reproductive health of male patients.
