Bilateral Leydig cell tumor in stallion
(Elsevier B.V., 2007-10-01)
The authors report a rare case of bilateral Leydig cell tumor in a noncryptorchid stallion, describing the gross. and microscopic findings. An 8-year-old Appaloosa stallion was examined for a unilateral enlargement of the ...
Anatomical study on domestical fowl (Gallus domesticus) reproductive system
(2007-12-01)
Lately, researchers have taken into consideration studies on birds since they represent an excellent nutritional source. There are several classical descriptions of the male reproductive tract, always aiming at establishing ...
Fipronil-induced decrease in the epididymal sperm count: Oxidative effect and protection by vitamin E
(2018-01-01)
The toxic effects of the insecticide fipronil on the sperm production and oxidative damage in the testis were evaluated, as well as the protective action of vitamin E. Male rats received vehicle or fipronil 5 mg/kg and ...

Testis structure, spermatogonial niche and Sertoli cell efficiency in Neotropical fish
(2019-03-01)
Neotropical icthyofauna represents one of the most diverse and extreme ecosystems in the world. Likewise, reproduction showed enormous diversity with different reproductive systems, modes and behavior. On the other hand, ...
Monoclonality of asynchronous bilateral lymphoma of the testis
(Karger, 2000-12-01)
Objectives: Lymphoma is the most frequent testicular malignancy in men over 60 years of age. Even though patients present initially with localized disease, the high incidence of bilateral involvement, synchronous or not, ...
Spermatic and testicular damages in rats exposed to ethanol: Influence of lipid peroxidation but not testosterone
(Elsevier B.V., 2015-04-01)
Chronic consumption of ethanol causes morphological and physiological changes in the reproductive system of mammals. Vitamin C has an antioxidant role in organisms by neutralizing the ROS (reactive oxygen species) produced ...
Involvement of soluble Fas Ligand in germ cell apoptosis in testis of rats undergoing autoimmune orchitis
(Elsevier, 2012-11)
Experimental autoimmune orchitis (EAO) is a model of chronic inflammation and infertility useful for studying immune and germ cell (GC) interactions. EAO is characterized by severe damage of seminiferous tubules (STs) with ...
Cytosolic glucocorticoid receptor in the testis of Bufo arenarum: Seasonal changes in its binding parameters
(Elsevier Inc, 2006-07)
Glucocorticoids (GC) are the hormonal mediators of stress. In mammals, high levels of GC have negative eVects on reproductive physiology. For instance, GC can inhibit testicular testosterone synthesis by acting via ...
IL17A impairs blood-testis barrier integrity and induces testicular inflammation
(Springer, 2014-09)
Experimental autoimmune orchitis is a useful model for studying testicular inflammation and germ/immune cell interactions. Th17 cells and their hallmark cytokine IL17A were reported to be involved in the development of ...
