An enzymologic study of corpora lutea in early pregnant rats treated with abortifacient agents is presented. Prostaglandin F2 alpha treatmen t (500 mcg twice daily 3 or 4 consecutive times) revealed an increase in corpora lutea glucose-6-phosphate dehydrogenase (G6PDH) activity of 110-140% and a moderate increase in 20 alpha-hydroxysteroid dehydrogenas e (20 alpha-
HSD
), whereas malic enzyme decreased to 27% of control values. Aminoglutethimide treatment (10-20 mg twice daily 6 or 7 consecutive times) revealed decreased G6PDH and malic enzyme activities while 20 alpha-
HSD
activity was maintained at a very low level. Corpora lutea of these aborted rats revealed moderately active 20 alpha-
HSD
valu es and slightly higher than control values for G6PDH, whereas malic enzy me activity fell to lower levels. Clomiphene citrate treatment (.5 ml of 3 mg/ml or .5 ml plus .5 ml of 10 mg/ml progesterone) caused abortion within 63 hours postinjection. G6PDH, malic enzyme, and adenosine triphosphate (ATP) citrate lyase activities in these corpora lutea decreased to 66, 68, and 72% of control levels, respectively, while 20 alpha-
HSD
activity was maintained at a very low level. Activities of 3beta hydroxysteroid dehydrogenase, 6-phosphogluconate dehydrogenase and pyruvate kinase were not appreciably altered. These results indicate that at the beginning of luteolysis and fetal resorption the activities of steroidogenic enzymes decreased and 20 alpha-
HSD
was not yet activated. Therefore, G6PDH, malic enzyme, and
ATP citrate lyase
activities could be measured to gauge early changes of luteolysis.
