Endometriosis was induced (autotransplant) in Wistar rats. After 21 days, the rats were randomly divided into two groups (16 female rats each). Control group was forced-fed 0.9% sodium chloride solution, and the ginger group was forced-fed 0.5 mg/100 g of Roscoe fresh extract, both by gavage, for 14 days, in addition to their normal diet. After that, an anesthetic dose (ketamine/xylazine) was administered until euthanasia. Peritoneal lavage fluid was collected to evaluate tumor necrosis factor (TNF)- and interleukin (IL)-6, and autotransplant was measured and excised to evaluate histology. The final mean volumes were larger in the control group (120.92 mm  ± 78.91) than in the ginger group (40.50 mm  ± 19.57) (  = .01). The endometriosis foci increased in the control group from 45.10 mm  ± 29.96 at 21 days postimplantation to 120.92 mm  ± 78.91 on the day of euthanasia (  = .02). In the ginger group, a slight increase was observed from 38.43 mm  ± 19.96 to 40.50 mm  ± 19.57, without statistical difference (  = .83). In addition, a greater increase in growth of the endometriosis foci was found when compared with the control (75.81 mm  ± 58.95) and ginger groups (2.07 mm  ± 18.87) (  = .004). No difference was found in TNF- (  = .51) and in IL-6 (  = .12). The degree of lesion atrophy was higher in the ginger group (1 ± 0.92) than in the control group (2.25 ± 1.16) (  = .03). The ginger extract reduced and atrophied autotransplanted endometriosis foci, but did not reduce IL-6 and TNF- in the peritoneal lavage fluid.
