OBJECTIVE: To investigate the possible involvement of collagen in the characteristic structure and function of human corpora lutea (CL), type V collagen expression was determined in the CL tissues during the menstrual cycle and early pregnancy. DESIGN: In vitro experiment. SETTING: Department of Obstetrics and Gynecology, Wakayama Medical University, Wakayama, Japan. PATIENT(S): Regulatory cycling women and pregnant women with ovarian tumor and ectopic pregnancy who underwent adnexectomy. INTERVENTION(S): Composition of the various types of collagen in human CL was analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. MAIN OUTCOME MEASURE(S): Expression of type V collagen. RESULT(S): The ratios of type III to type I collagen and the ratios of type V to type I collagen in the CL tissues were significantly increased in early pregnancy compared with those in the menstrual cycle. CONCLUSION(S): These results suggest that alterations in composition of collagen might play an important role in determining the physiology and structure of the CL during the menstrual cycle and early pregnancy.
