Efficient association between PGF2α and methyl 4-hydroxybenzoate sex pheromone prior to electroejaculation in dogs.

摘要: Electroejaculation is a technique that can be used to collect semen from canines, but its use with this group of animals restricted by low success rate and quality. Here, we evaluated whether pharmacological sexual sensory stimuli, which may affect ejaculation, increase electroejaculation efficiency improve ejaculate We worked 20 dogs mixed breed weighing between 5.3 22.2 kg, divided into two groups. Both groups were exposed spayed female for 10 min, in the second group, same had her vagina impregnated methyl 4-hydroxybenzoate synthetic pheromone min after receiving dinoprost tromethamine IM, 0.1 mg/kg. After stimulation, all chemically restrained ketamine, 8 mg/kg, IM; xylazine, 1 subjected protocol. obtained 100% antegrade treatments when 80% she did not. Sperm motility was significantly different (p < 0.05) controls test (10.1 ± 4.5 43.0 8.3, respectively). concluded adopted protocol efficient PGF2α associated stimulation quality undergoing procedure.
