Effect of the primary cooling rate on the motility and fertility of frozen-thawed rabbit spermatozoa

Maeda, Tatsuhiro; Liu, Enqi; Nishijima, Kazutoshi; Tanaka, M.; Yamaguchi, Shinji; Morimoto, Masatoshi; Watanabe, Teruo; Fan, Jianglin; Kitajima, Shuji (Editorial Universitat Politècnica de València, 2012-06-30)

[EN] In the present study, we examined the effect of primary cooling rates on the motility and fertility of frozen-thawed rabbit spermatozoa. Rabbit semen diluted with an egg-yolk acetamide extender was cooled from room ...
First production of larvae using cryopreserved sperm. Effects of preservation temperature and cryopreservation on European eel sperm fertilization capacity

Asturiano Nemesio, Juan Francisco; Sorensen, S.R.; Pérez Igualada, Luz María; Lauesen, P.; Tomkiewicz, J. (Blackwell Publishing, 2016)

[EN] Contents Sperm cryopreservation is a useful tool in captive fish reproduction management, that is to synchronize gamete production, especially in the case of species as the European eel, where the time of female ...
Fish sperm motility assessment as a tool for aquaculture research, a historical approach

Gallego Albiach, Victor; Asturiano Nemesio, Juan Francisco (Blackwell Publishing, 2018)

[EN] Fish sperm motility is nowadays considered the best biomarker for the quality of fish spermatozoa, and sperm motion parameters from more than 300 fish species have been reported in more than 1500 scientific articles ...
Guidelines for the handling of rabbit bucks and semen

International Rabbit Reproduction Group. (World Rabbit Science. ICTA. UPV, 2005)

[EN] This paper contains recommendations for procedures to be used in applied reproduction trials performed with rabbit bucks and/or semen. The factors influencing sperm production (environment, age, health status and ...
Influencia de la temperatura durante el procesamiento y análisis seminal humano sobre los parámetros de calidad espermática relativos al estado del ADN y la morfología

Cerveró Bosch, Clara (Universitat Politècnica de València, 2019-10-21)

[ES] La reproducció assistida és una pràctica mèdica de gran valor per a la societat actual ja que permet fer front als problemes de fertilitat i als distints models familiars. Existeixen diverses tècniques de reproducció ...
Managing Sexual Receptivity and Ovulation Induction in Rabbit Does: Evidence from Recent Research

Rebollar, Pilar G.; Arias-Álvarez, María; Lorenzo, Pedro L.; García-García, Rosa M. (Universitat Politècnica de València, 2023-06-30)

[EN] The sexual receptivity and ovulation induction of the reproductive rabbit are key points determining their success in productive life. Adequate synchronisation of the sexual receptivity methods of inseminated rabbit ...
Sperm physiology and quality in two marine teleosts: Anguilla anguilla & Takifugu niphobles

Gallego Albiach, Victor (Universitat Politècnica de València, 2013-12-20)
