"In vitro" effect of progesterone on alpha-L-fucosidase activity of human endometrium.

Alpha-L-fucosidase activity was found to be increased in organ cultured normal endometrium and in endometrial adenocarcinoma compared with non cultured tissue. The enzyme activity was lowered with addition of progesterone to the medium. Non cultured adenocarcinoma showed a higher activity compared with non cultured normal endometrium.
