本文选用15组(每组3～4只)健康的成年雄性小白鼠,从附睾尾和输精管中取出精子,分别在37℃、40℃、43℃温育3小时后,进行体外受精,测定精子穿透率,分别为54.1％、56.2％和46.4％,对照组与温热组穿透率差异无统计学意义。从而进一步说明小白鼠精子对温热不敏感。 In this study, 15 healthy adult male mice (3-4 per group) were selected and spermatozoa were removed from the epididymal tail and vas deferens. After 3 hours of incubation at 37, 40 and 43 ℃ respectively, in vitro fertilization was performed to determine sperm Penetration rates were 54.1%, 56.2% and 46.4%, respectively, while there was no significant difference between the control group and warm-warm group. To further explain the mouse sperm is not sensitive to heat.
