Spermatocytic tumor (ST) is a very rare disease, accounting for approximately 1% of testicular cancers. Previously classified as spermatocytic seminoma, it is currently classified within the non-germ neoplasia in-situ-derived tumors and has different clinical-pathologic features when compared with other forms of germ cell tumors (GCTs). A web-based search of MEDLINE/PubMed library data was performed in order to identify pertinent articles. In the vast majority of cases, STs are diagnosed at stage I and carry a very good prognosis. The treatment of choice is orchiectomy alone. Nevertheless, there are two rare variants of STs having very aggressive behavior, namely anaplastic ST and ST with sarcomatous transformation, that are resistant to systemic treatments and their prognosis is very poor. We have summarized all the epidemiological, pathological and clinical features available in the literature regarding STs that have to be considered as a specific entity compared to other germ GCTs, including seminoma. With the aim of improving the knowledge of this rare disease, an international registry is required.

Testicular cell differentiation is a highly regulated process, essential for male reproductive health. The histone variant H3.5 is apparently a critical player in this intricate orchestra of cell types, but its regulation and function remains poorly understood.

Introduction: Bilateral testicular tumours occur in 3-5% of all cases with testicular neoplasms. In the majority of cases, histology of the two new growths is identical. The time interval between the two neoplastic events rarely exceeds 10 years.

The aim of this study was to deepen our understanding of the reproductive biology of male spotted wolffish () using two different experimental approaches involving juvenile and mature broodstock fish. The first approach consisted of a detailed histological examination of the testes to identify the onset of gonadal maturation and characterise the spermatogenic stages in two- and three-year-old juvenile specimens. Light microscopy analysis revealed clear differences between the age groups.

Objective: The CHOP combined chemotherapy regimen (cyclophosphamide, doxorubicin, vincristine, and prednisone) is commonly used to treat non-Hodgkin Lymphoma (NHL). While these drugs are effective for cancer treatment, they may have side effects on the reproductive system that are poorly studied. This study used a mouse model to investigate the mechanisms of reproductive function impairment induced by the CHOP regimen and developed a predictive model for assessing reproductive damage with a non-invasive procedure.
