Objective:
To assess the level of lipid peroxidation in the peritoneal fluid of infertile women with peritoneal endometriosis and of fertile disease-free controls.
Study Design:
Level of lipid peroxidation (malondialdeyde, malondialdeyde with copper addition, and cholest-3,5-dien-7-one) was measured in the peritoneal fluid obtained from 21 women with endometriosis-related infertility and from 21 fertile women having tubal ligation.
Results:
: The level of lipid peroxidation did not differ significantly (P > 0.05) according to the stage of endometriosis. The level of lipid peroxidation (malondialdeyde, malondialdeyde with the addition of copper, and cholest-3,5-dien-7-one) did not differ significantly (P > 0.05) between patients with endometriosis-related infertility (0.07 nmol/ml, 0.34 nmol/ml, 0.24 microg/ml, respectively) and disease-free controls (0.04 nmol/ml, 0.21 nmol/ml, 0.25 microg/ml, respectively).
Conclusion:
The level of lipid peroxidation did not differ between women with endometriosis-related infertility and fertile disease-free controls, suggesting that increased reactive oxygen species may not be one of the factors responsible for compromised fertility in patients with endometriosis.
