13. Morfometria testicular em ratos wistar adultos tratados com paracetamol (acetaminofeno) / Testis morphometry in adult Wistar rats treated with acetaminophen
Acetaminophen is non-prescrition analgesic and antipyretic considered safe and well tolerated in therapeutics doses, but it might cause hepatic and extrahepatic damage in animal and human models exposed to high doses. The chronic use of paracetamol in supratherapeutics doses has been implied in testicular lesions and sexual behavior alterations in animal mod

14. Effects of the association of cadmium chloride and guarana (Paullinia cupana) on the testis of wistar rats : morphometry, structure and ultrastructure / Efeitos da associação de cloreto de cadmio e guarana (Paullinia cupana) no testiculo de ratos Wistar : analise morfometrica, estrutural e ultraestrutural
Guaraná (Paullinia cupana Mart. var. Sorbilis) is a Brazilian plant, found in the Amazon basin. Previous studies have demonstrated the antioxidant properties of guaraná and its potential to neutralize free radicals. This plant is traditionally used for several therapeutic purposes and, recently, has been investigated to ascertain the potential of guaraná

15. Association of cyclosporine and Heteropterys aphrodisiaca (no-de-cachorro) administered to Wistar rats : testicular structure, ultrastructure and morphometry / Associação de ciclosporina e Heteropterys aphrodisiaca (no-de-cachorro) adminstrados a ratos wistar : estrutura, ultra-estrutura e morfometria testicular
Cyclosporine A (CsA) has potent immunosuppressive properties and it has markedly improved the ability of transplant patients to survive grafts and is also used in some autoimmune diseases. However, the drug has several side effects, including testicular toxicity, leading to male infertility (and temporary impotence). Stimulant and aphrodisiac properties has

16. Morfometria testicular de ratos Wistar adultos tratados com infusão aquosa de catuaba (Trichilia catigua A. Juss. Meliaceae) / Testicular morphometry of adult Wistar rats treated with aqueous infusion of catuaba (Trichilia catigua A. Juss. Meliaceae)
Throughout the last decades, it was observed an increase of the search for substances of vegetal origin, which can act in the reproductive organs assisting in the performance of the sexual functions, mainly of males. However, a few works have been doing to evaluate the effect of those substances in the reproductive organs. The effect of the extracts of Trich

17. Association of cadmium and Ginko biloba in rats tests : structure, ultrastructure and morphometry / Associação de cadmio e Ginko biloba em ratos : avaliação dos testiculos quanto a modificações de estrutura, ultra-estrutura e morfometria
o cádmio (Cd) é um dos poluentes ambientais importantes que causam danos a vários órgãos e tecidos, incluindo os testículos. O objetivo deste trabalho é investigar o efeito protetor e curativo do extrato de G biloba (GbE) nos testículos de ratos adultos Wistar tratados com dose única de Cd. Trinta animais foram divididos aleatoriamente em 5 grupos q

18. Wild boars (Sus scrofa scrofa) seminiferous tubules morphometry
Objetivou-se com esta pesquisa estudar as características morfométricas e funcionais dos túbulos seminíferos de javalis adultos. Utilizaram-se testículos de cinco animais submetidos a orquiectomia unilateral. O parênquima testicular foi composto por 82,1 ± 2,2% de túbulos seminíferos e 17,9 ± 2,2% de tecido intertubular. O diâmetro tubular foi de

19. Avaliação morfológica do aparelho reprodutor masculino e morfometria dos testículos de Chromacris speciosa (Thunberg,1824) (Orthoptera : Romaleidae) submetido a três fotoperíodos / Morphological evaluation of the male reproductive system and texticle morphometry of Chromacris speciosa (Thunberg,1824)(Orthoptera : Romaleidae) submitted to three photoperiods
O regime alimentar dos ortópteros é bastante variado, praticamente da monofagia à polifagia, predominando,todavia, a fitofagia, daí serem altamente nocivos às plantas cultivadas e, por isso mesmo, economicamente importantes sob o ponto de vista agrícola. Chromacris speciosa (Thunberg, 1824) (Orthoptera: Romaleidae) é considerada como devastadora ocasi

20. Morphofunctional analysis of the testis and spermatogenesis in adult African lions (Panthera leo, Linnaeus, 1758) / Análise morfofuncional do testículo e espermatogênese de leões africanos (Panthera leo, Linnaeus, 1758) adultos
The study of the testis morphology and the spermatogenetic process in wild animals is fundamentally important for the knowledge about the physiologic patterns by which the assisted reproduction protocols are established. The following objectives were proposed in this study: to describe the data of both testis morphometry and seminiferous tubule; to quantify

21. Estrogen-Induced Developmental Disorders of the Rat Penis Involve Both Estrogen Receptor (ESR)- and Androgen Receptor (AR)-Mediated Pathways1
This study tested the hypothesis that the estrogen receptor (ESR) pathway, androgen receptor (AR) pathway, or both mediate estrogen-induced developmental penile disorders. Rat pups received diethylstilbestrol (DES), with or without the ESR antagonist ICI 182,780 (ICI) or the AR agonist dihydrotestosterone (DHT) or testosterone (T), from Postnatal Days 1 to 6
