Effects of cow's milk on reproduction in ICR male mice / 生物医学与环境科学（英文）

ABSTRACT

<p><b>OBJECTIVE</b>To study the effects of Cow's milk on the reproduction in male mice.</p><p><b>METHODS</b>Twenty-four male mice were divided randomly into two groups: milk group (M) and control group (C). Each mouse was given 10 mL milk per day from 4 to 16 weeks in the group M. At the age of 17 weeks, all the mice were sacrificed.</p><p><b>RESULTS</b>Serum testosterone was decreased in the group M (P=0.037). No significant difference was found in weight of testes, seminal vesicle or adrenal gland of mice between the groups C and M. However, the weight of seminal vesicle decreased when expressed in g/100 g body weight in the group M. Epididymal sperm concentration, motility, morphology, and sperm head number were not affected by milk.</p><p><b>CONCLUSION</b>Cow's milk has adverse effects on the reproductive system in ICR male mice. Further studies are needed to clarify the specific effects of milk on reproductive health.</p>
