1. Can we use LDL instead of egg yolk in BotuCrio® extender to cryopreserve sperm from the Mangalarga Marchador stallion?
Abstract The objective of this study was to compare the BotuCrio® extender with the Merk - egg yolk and the INRA 82 modified by the inclusion of acetamide, methyl cellulose and trehalose in substitution of glycerol for freezing equine semen. The semen was diluted after centrifugation to obtain 100 x 106 of sperm/ml in: BotuCrio® (control); Merk - egg yolk

2. Reproductive toxicity of neem seeds (Azadirachta indica) in male quail (Coturnix coturnix japonica)
RESUMO: Considerando que o neem (Azadirachta indica A. Juss.) causa efeitos deletérios na fertilidade, objetivou-se avaliar o efeito da alimentação com sementes de neem sobre a qualidade seminal, parâmetros biométricos e morfometria testicular com codornas (Coturnix coturnix japonica Linnaeus, 1758) com 90 dias de idade, como modelo experimental. Após

3. Improvement of fertility parameters with Tribulus Terrestris and Anacyclus Pyrethrum treatment in male rats
ABSTRACT Objective Anacyclus Pyrethrum (AP) and Tribulus Terrestris (TT) have been reported as male infertility treatment in several studies; however, in Iranian traditional medicine these two plants are prescribed simultaneously. In this study, we aimed to determine the effects of AP and TT extracts both separately and simultaneously on the male Wistar ra

5. Efeito da adição de plasma seminal oriundo de animais de alta e baixa fertilidade na criopreservação de espermatozoides da cauda do epidídimo e do ejaculado de garanhões subférteis
RESUMO O objetivo do presente estudo foi avaliar o efeito da adição de plasma seminal de garanhões de alta e baixa fertilidade sobre a congelabilidade e a viabilidade de espermatozoides do ejaculado (EJ) e do epidídimo (EP) de garanhões subférteis. Foram utilizados seis garanhões com histórico de subfertilidade. Após coleta, espermatozoides do ejacu

6. Protective Effect of Rosa Canina Extract Against Doxorubicin-induced Testicular Toxicity in Mice
Abstract The present study was aimed to investigate the in vivo effects of Rosa canina extract on doxorubicin-induced testicular toxicity in mice for the first time. Male NMRI mice were randomly divided into six treatment groups (10=per group) as follows: (I) vehicles, (II) doxorubicin alone (3 mg/kg, i.p. on days 7, 14 and 21), (III and IV): Rosa canina ext

7. SUPLEMENTAÇÃO DE SELÊNIO NA DIETA E QUALIDADE ESPERMÁTICA DO SÊMEN DE TOUROS BRANGUS
Resumo Objetivou-se avaliar a qualidade espermática do sêmen de touros suplementados com selênio (Se) na dieta. Foram utilizados 16 touros Brangus, igualmente distribuídos em grupo controle (GC) e grupo Se (GSe − 0,1mg de Se/kg de MS de dieta). O experimento teve duração de 75 dias, e os animais foram suplementados por 60 dias. Foram realizadas quatr

9. Pollen has higher water content when dispersed in a tricellular state than in a bicellular state
ABSTRACT Pollen is generally dispersed in a sexually immature and somewhat dehydrated, metabolically quiescent state. Yet, in some species, pollen at anthesis is well-hydrated and metabolically active, and in 30 % of angiosperms pollen is dispersed after having formed its sperm cells. Pollen water content and sexual maturity may be correlated, either because

10. Star anise extracts modulation of reproductive parameters, fertility potential and DNA fragmentation induced by growth promoter Equigan in rat testes
ABSTRACT Equigan is an anabolic steroid that has been developed for veterinary use and derived from endogenous sex hormone testosterone that plays a key role in the development of male reproductive tissue as well as in puberty and spermatogenesis. The current study is aimed to investigate the possible prophylactic effect of star anise extracts (SAE) on the t

11. Aggravation of cyclophosphamide-induced reproductive toxicity in mice by aqueous extract of Aegle marmelos (L.)
ABSTRACT Aegle marmelos (L.) (Rutaceae) commonly known as bael is an important medicinal fruit tree. The present study focused on the effects of aqueous extract of Aegle marmelos (AEAM) on the testis and sperm characteristics induced by cyclophosphamide (CPA) in mice. Thirty six adult Parke’s strain mice were divided into six groups: group I given only dis

12. Biochemical and seminal parameters of lambs fed palm kernel cake under grazing system
ABSTRACT This study aimed to assess the effects of palm kernel cake on semen quality and biochemical parameters of Santa Inês lambs. A total of 40 animals with 24.10±2.72 kg body weight and five months old were assigned in a completely randomized design into four groups and 10 replicates. The animals were subjected to four levels of palm kernel cake (0, 15
