Ovaries and adrenals in murine Schistosomiasis mansoni. II. Some observations on the function of the ovaries in acute infection.

In mice with acute schistosomiasis mansoni the mean serum level of progesterone, as determined by radioimmunoassay, was significantly lower than in non-infected control animals, probably due to the atrophy of corpora lutea and the discontinuance of their development described in an earlier paper. In spite of the histopathological changes in the ovaries and the decreased level of progesterone in the blood, estrus was present in some infected animals.
