The peritoneal environment in endometriosis is known to have growth-
promoting effects on endometrial cells. To investigate whether follicular
fluid, a contributor to the peritoneal fluid, stimulates endometrial cell
proliferation, we incubated endometrial stromal cells in culture with
various dilutions of follicular fluid obtained from women with or without
endometriosis undergoing oocyte retrieval for in- vitro fertilization. Cell
proliferation assays were performed using follicular fluid from 28 women
(without endometriosis, n = 13; with endometriosis, n = 15) in eight
different endometrial stromal cell culture set-ups. Cell proliferation was
assessed by a colorimetric method. Maximum cell proliferation was detected
when endometrial cells were incubated with 50% dilution of follicular fluid
for 48 h. Follicular fluid from women with endometriosis induced
significantly higher cell proliferation than follicular fluid from women
without endometriosis (P < 0.05). Our findings indicate that follicular
fluid contents may contribute to the growth-promoting factors in the
peritoneal fluid of women with endometriosis.
