RESUMO
Sixty follicular fluids obtained from 26 women with either clomiphene citrate and human menopausal gonadotropins (hMG) or hMG-induced ovulation were analyzed for the contents of total proteins, fibrinogen, plasminogen, antithrombin III, ceruloplasmin, alpha-2 macroglobulin, alpha-1 antitrypsin and immunoglobulins (IgG, IgA, IgM). Concentrations of these proteins was correlated to the type of ovarian follicle growth induction. Follicular fluids from patients stimulated with clomiphene citrate-hMG contained significantly higher concentrations of ceruloplasmin than those treated with hMG alone. No significant differences in the concentrations of other proteins were noted between the two types of ovarian induction. A multivariate data analysis resulted in three Varimax factors (VRX I) suggesting that proteins with antiprotease activity in the follicular fluid may play a role in human follicle maturation. Follicular fluid Ig may reflect the degree of follicular wall permeability under hMG treatment. Accordingly, it may be assumed that a combination of different proteins described by VRX factors could be used for evaluation of ovarian stimulation.
