The white tea in a healthy drink, but this tea can interfere in some growth factors involved in the reproduction and in the metabolism. So, the aim of this work was to verify the effect of the white tea consumption in the metabolism, number of corpora lutea and in the weight of superovulated rats. There were utilized two groups of rats: control (n=30) that received water and the group that received only white tea to drink (n=30). The experiment lasts three months and the liquid and ration consumption were verified. In the end of each month, 10 rats of each group were superovulated with 150 UI/Kg of eCG, and 150UI/Kg of hCG 48 hours later. After 48 hours of the superovulation, the rats were weighted, sacrificed and the ovaries were weighted and the corpora lutea counted, besides the blood of animals were collected for hemogram and serum biochemistry. Não houve diferença no número de corpos lúteos e peso dos ovários entre os grupos. The statistical analysis was ANOVA test followed of Tukey analysis, differences were considered when P<0.05. The group treated with white tea showed higher ingestion of ration (39.63 &#61617; 3.91 g) than control group (37.19 &#61617; 4.00 g; P<0.05). However there wasn t any difference in the animals weight. Moreover, the treated group presented lower cholesterol concentration (32.02 &#61617; 9.62 mg/dL) than control group (76.70 &#61617; 10.41 mg/dL; P<0.05). No one statistical difference was observed in the number of corpora lutea, neither in the ovaries weight between the groups. The conclusion that white tea inhibis the excessive weight gain and decreases the cholesterol concentration; furthermore the white tea does not interfere with number of corpora lutea neither in the ovaries weight of superovulated rats.
