OVARIAN STIMULATION BY ADRENAL EXTRACTS†

Abstract
Extracts from adrenals of pregnant and non-pregnant mares and from geldings were injected twice daily for 5 days into 82 female rats 21-25 days old. Subsequent examination of the ovaries showed: large follicles or corpora lutea; ovulation in 50% of animals. Extracts of blood, blood serum, liver and ovaries from horses were without ovarian effect.
