Alpha-fetoprotein (AFP)-producing primary lung tumours are rare; we present the first case of an AFP-producing lung tumour with metastasis to testes. The patient, a 72-year-old man, presented with a history of flu-like symptoms and abdominal pain. On examination he had a hard, tender left scrotal mass. Imaging showed a 4.4-cm right lower lobe lung mass and the serum-AFP was raised (1189 ng/mL)....

Several clinicopathological illnesses impact the testis and paratesticular area, which are divided into non-neoplastic neoplastic diseases. Despite availability of imaging tumor marker testing, histopathological examination is primary method for diagnosing testicular lesions. Common indications orchidectomy lesions cryptorchidism, epididymitis torsion. Few non- present as mimickers neoplasm wit...

Declines in skeletal muscle size and strength, often seen with chronic wasting diseases, prolonged or high-dose glucocorticoid therapy, and the natural aging process in mammals, are usually associated with reduced physical activity and testosterone levels. However, it is not clear whether the decline in testosterone and activity are causally related. Using a mouse model, we found that removal o...

Both estrogens and androgens act on bone marrow stromal/osteoblastic cells to inhibit the production of local factors that promote osteoclast development. Based on this and the evidence that loss of sex steroids up-regulates not only osteoclastogenesis but also osteoblastogenesis, we have hypothesized that cells of the osteoblastic lineage are the mediators of the adverse effects of sex steroid...

Unilateral orchidectomy (UO) is required when further breeding potential is important. It is sometimes necessary to remove a single testis in a matured stallion for therapeutic reasons. In this study, twelve donkeys were used to evaluate three techniques of unilateral castration, histological and morphological changes on the remaining testis. Results of the study showed that each of the surgica...
