Abstract

OBJECTIVE: Our purpose was to determine in the rat model whether endometriosis could influence ovarian function by altering oocyte release or folliculogenesis. STUDY DESIGN: We histologically examined the ovaries of reproductively cycling rats with (n = 16) and without (n = 10) surgically induced endometriosis. The rats in these two groups were further subdivided into unilaterally ovariectomized or ovarian-intact groups. Serial sections of ovaries were examined, and follicular development and frequency of luteinized unruptured follicles were determined. RESULTS: A significant tenfold increase in the number of luteinized unruptured follicles was observed in the ovaries from rats with endometriosis (2.7 per rat) compared with unoperated and sham-operated control groups (overall mean 0.26 per rat, p < 0.05). Additionally, ovaries from unilateral ovariectomized animals with endometriosis contained four times as many luteinized unruptured follicles (four per rat) as did the ovaries from bilaterally ovarian-intact rats with endometriosis (1.40 per rat, p < 0.01). Fewer follicles were present in rats with endometriosis (180 follicles per ovary) than in control rats (231 follicles per ovary, p < 0.05). CONCLUSION: In the rat model the presence of ectopic endometrium is associated with an increased frequency of luteinized unruptured follicles and altered follicular development.
