1. Reproductive effects of the psychoactive beverage ayahuasca in male Wistar rats after chronic exposure
Abstract Ayahuasca is a psychoactive beverage used ancestrally by indigenous Amazonian tribes and, more recently, by Christian religions in Brazil and other countries. This study aimed to investigate the reproductive effects of this beverage in male Wistar rats after chronic exposure. The rats were treated by gavage every other day for 70 days at 0 (control)

2. Extracts effect of Heteropterys aphrodisiaca O. Mach. (nó- de-cachorro) and Anemopaegma arvense (Vell.) Stellfeld &J.F. Souza (vergateza) on the testicle and the spermatogenic process of adults rats Wistar / Efeitos dos extratos de Heteropterys aphrodisiaca O. Mach. (nó-de-cachorro) e Anemopaegma arvense (Vell.) Stellfeld &J.F. Souza (vergateza) sobre o testículo e o processo espermatogênico de ratos Wistar adultos
No Brasil, o uso das plantas medicinais constitui uma forma direta de obtenção de medicamentos, e com base nos saberes e práticas tradicionais ocupam lugar de destaque no tratamento de doenças. Entre várias utilidades, o uso afrodisíaco desperta interesse especial da população e substâncias de diversas espécies são consumidas com esta finalidade.

3. 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

4. Efeito da infusão do caule de cipó-cravo (Tynnanthus fasciculatus Miers, Bignoniaceae) sobre as características morfométricas de componentes testiculares de ratos Wistar adultos / Infusion effect of the stem herb (Tynnanthus fasciculatus Miers, Bignoniaceae) on the morphometric characteristics of testis components of adult rats Wistar
Nos últimos anos tem aumentado a procura de substâncias de origem vegetal na busca constante da resolução das disfunções sexuais, especialmente masculinas. O cipó-cravo, Tynnanthus fasciculatus, é uma planta utilizada como medicamento caseiro para combater má digestão e dores no estômago, e também adotada popularmente como estimulante geral e afr

5. Reproductive characteristics of ligth and semi-heavy roosters submitted to different photoperiods / CaracterÃsticas reprodutivas de galos leves e semi-pesados submetidos a diferentes fotoperÃodos.
With the objective of evaluating the effects of differents photoperiods on the reproductive parameters in roosters of light and semi-heavy strains, an experiment was conducted in the Animal Science Department of the Federal University of Lavras. 24 roosters of the Lohman LSL strain (light) and 24 roosters of the Lohman Brown strain (semi-heavy), aged 19 week

6. 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

7. Secretion of Unconjugated Androgens and Estrogens by the Normal and Abnormal Human Testis before and after Human Chorionic Gonadotropin
The secretion of androgens and estrogens by normal and abnormal testes was compared by determining the concentrations of dehydroepiandrosterone (DHEA), androstenedione (Δ4A), testosterone (T), estrone (E1), and 17β-estradiol (E2) in peripheral and spermatic venous plasma samples from 14 normal men and 5 men with unilateral testicular atrophy. Four normal m

8. Estradiol and Testosterone Secretion by Human, Simian, and Canine Testes, in Males with Hypogonadism and in Male Pseudohermaphrodites with the Feminizing Testes Syndrome
The role of the human testis in the production of 17β-estradiol (E2) was investigated by determining the concentration of E2 and testosterone in peripheral and spermatic vein plasma samples. Specimens were obtained from eight normal men, three men with hypogonadism, and two patients with the incomplete form of the feminizing testes syndrome. For comparison,
