Spermary promotes sexual behavior,gonadal development and sperm count production in male zebrafish
Objective To explore the effects of spermary on sexual behavior,gonadal development and sperm count production.Methods Fifty-six male zebrafishes of 10-month-old AB strain after fertilization were randomly divided into 7 tanks and set up as the normal group,model group,positive control group(clomiphene citrate group,Wuzi Yanzong Pills group),and Spermary low,medium and high concentration groups,8 fishes in each group.Except for the normal group,cyclophosphamide was given in water solution to establish the zebrafish oligospermia model,respectively.On 9 d of modeling,the positive control group was ad-ministered at a concentration of 0.1 μg/mL in the clomiphene citrate group and 6 μg/mL in the Wuzi Yanzong Pill group;the spermary low,medium and high concentration groups were administered at 200,300,900 μg/mL,respectively.On 16 d of modeling,the normal female zebrafishes were placed in the culture tank of each group in a 1∶1 ratio,and the frequency of tail-chasing was observed and recorded in male and female fishes.The body length,weight,testis weight and sperm count were measured and the statistical analysis was performed by comparing the differences among the groups before and after drug administration(one-way ANOVA).Results Com-pared with the normal group,the frequency of tail-chasing of zebrafishes,body length,body weight,testis weight and sperm count in the model group were significantly decreased(P＜0.05).Compared with the model group,the frequency of tail-chasing of zebrafishes,body length,body weight,testis weight and sperm count in the spermary low,medium and high concentration groups all were significantly increased(P＜0.05),in which the vitality change of sexual behavior in the spermary medium concentration group was most obvious,and the increase of sperms count was most obvious.Conclusion A certain dose of spermary could effectively promote the sexual behavior,gonadal development and sperm count production in male zebrafish with oligospermia.The efficacy of spermary in enhancing the male sexual function and treating oligozoospermia and infertility de-serves to be studied.
