Llama (Lama glama) semen collection via thermo-electric artificial vagina: effect of seasonality and collection interval on ejaculate characteristics
(Elsevier, 2015-09-09)
Adult male Llamas (Lama glama) (n = 6) were collected using a receptive female and a thermo-electric artificial vagina assembled with a polyethylene collection bag with the following objectives: (a) to develop a reliable ...
Electrostimulation is an effective and safe method for semen collection in medium-sized lizards
(Elsevier Science Inc, 2018-09)
The development of safe and consistent semen collection protocols should be ensured to understand basic sperm parameters of a species. Electroejaculation has been hypothesized and tested to be a safe method to evaluate ...
Effect of egg yolk-based extender and seminal plasma removal on sperm viability of cooled donkey semenEfeito do diluente à base de gema de ovo e remoção do plasma seminal na viabilidade espermática do sêmen refrigerado de jumento
(Universidade de São Paulo, 2021-03-23)
Developing effective cooled semen protocols is essential to increase pregnancy rates and reproductive efficiency in donkeys. This study aimed to evaluate the effect on sperm kinetic parameters and membrane integrity in ...
Seminal plasma proteins modify the distribution of sperm subpopulations in cryopreserved semen of rams with lesser fertility
(Elsevier Science, 2017-09-27)
Any physiological mechanism involved in sperm selection and semen improvement has effects on heterogeneous sperm populations. This is mainly due to the fact that sperm populations within a single ejaculate have considerable ...
Patients with chronic prostatitis/chronic pelvic pain syndrome show T helper type 1 (Th1) and Th17 self-reactive immune responses specific to prostate and seminal antigens and diminished semen quality
(Wiley Blackwell Publishing, Inc, 2020-09)
Objectives: To assess the presence of self-reactive immune responses to seminal and prostate antigens (PAg), biomarkers of inflammation of the male genital tract, and semen quality parameters in patients with chronic ...
Modeling of behavioral responses for successful selection of easy-to-train rams for semen collection with an artificial vagina
(Elsevier Science, 2018-05)
The aim of this study was to analyze the reproductive behavioral responses in Australian Merino rams, to identify those related to a faster training for semen collection with an artificial vagina. Eight Australian Merino ...
Hormonal levels and semen parameters of Criollo breed stallions under intensive training
(Elsevier Science Inc., 2020-06)
The stress associated with intensive training may reduce reproductive efficiency in Criollo stallions. The objective was to compare semen quality and cortisol, testosterone, and estradiol levels in Criollo stallions under ...
Reproduction in chinchilla (Chinchilla lanigera): Current status of environmental control of gonadal activity and advances in reproductive techniques
(Elsevier Science Inc, 2012-04-30)
A review of the biology of reproduction of chinchilla, focusing on environmental control of the gonadal activity, is presented. Chinchilla is a South American hystricomorph rodent genus currently considered almost extinct ...
Use of Androcoll-ETM to Separate Frozen-Thawed Llama Sperm From Seminal Plasma and Diluent
(Frontiers Media, 2021-01)
It is not easy to separate frozen-thawed South American camelid sperm from seminal plasma (SP) and diluents to be used for in vitro embryo production. The objective of this study was to evaluate Androcoll-E™ (AE) efficiency ...
