Resumo: The present research was carried out to investigate the relationships between spermatozoal parameters and concentrations of IGF-I in the seminal plasma of boar. Semen samples (duplicates) were collected from mature boars (n=27). In each ejaculate, the macroscopic and microscopic characteristics were determined. After centrifugation to separate sperm cells from seminal plasma, concentrations of IGF-I in seminal plasma samples were determined by a human-specific immunoassay kit. The mean concentration of the boar seminal plasma (n=54 samples) IGF-I was 1.5±0.2 ng/mL. There was no correlation (p>0.05) between IGF-I with most of the evaluated parameters. There was only a low negative correlation (-0.29; p=0.0331) between the concentration of IGF-I in seminal plasma and the motility degradation rate. This study suggests that IGF-I in the seminal plasma of boars is not related to initial fresh semen parameters. However, the hormone did increase the duration of sperm motility.

Amostras de sêmen (duplicatas) foram coletadas de machos maduros (n=27). Em cada ejaculação, as características macroscópicas e microscópicas foram determinadas. Após a centrifugação para separar espermatozóides do plasma seminal, as concentrações de IGF-I em amostras de plasma seminal foram determinadas por kit de imunoensaio humano específico. A concentração média de IGF-I do plasma seminal de varrões foi de 1,5±0,2 ng/mL (n=54 amostras). Não houve correlação (p>0,05) entre IGF-I com a maioria dos parâmetros avaliados. Houve apenas uma correlação baixa negativa (-0,29, p=0,0331) entre a concentração de IGF-I no plasma seminal e a taxa de degradação da motilidade. Este estudo sugere que o IGF-I no plasma seminal de varrões não está relacionado com os parâmetros seminais iniciais do sêmen in natura. No entanto, o hormônio aumentou a duração da motilidade espermática.Universidad de Córdoba2020-03-05T19:31:46Z2020-03-05T19:31:46Z2013-09info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfZANGERONIMO, M.
