Impact of Cold Exposure on the Reproductive Function in Female Rats

Figure 2

(a) Microphotographs (10×10) of cellular characteristics for the identification of the estrus stage. A proestrus smear mainly consisted of nucleated epithelial cells (I); an estrus smear primarily consisted of anucleated cornified cells (II); a metestrus smear consisted of the same proportion among leukocytes, anucleated cornified cells, and nucleated epithelial cells (III); a diestrus smear primarily consisted of leukocytes (IV). (b) Effects of cold exposure on estrus cycle (n=12). Values were presented as the mean value ± standard error. p < 0.05 and p< 0.01.
