Lipid and lipoprotein contents of XXXX follicular fluid.

@entity1 @entity1420 @entity4082 @entity1674 @entity165
The concentrations of total @entity165 , phospholipids, @entity1674 and lipoproteins were measured in 87 follicular fluids obtained from 35 @entity1 undergoing in vitro fertilization and embryo transfer. The results were correlated with the levels of @entity1420 in follicular fluid. Two different types of ovarian stimulation were used. High density lipoproteins were the dominant lipoproteins found in the preovulatory follicular fluid. Low density lipoproteins were absent or appeared in trace amounts. Significantly higher @entity1674 and high density lipoprotein levels were found when stimulation with @entity1 menopausal gonadotropins and chorionic gonadotropin was applied, as compared to the @entity4082 -menopausal gonadotropin-chorionic gonadotropin menstrual cycle. In both groups, extracorporal fertilization resulted in cleavage of oocytes and embryo transfer. No significant correlation between any follicular fluid lipid and @entity1420 concentration was found. The lipids estimated in the follicular fluid appeared to have no influence on the oocyte fertilizability. The presence of @entity1674 and high density lipoproteins in the follicular fluid may indicate follicular wall permeability under the treatment with menopausal gonadotropins.
