Morphine inhibition of ovulation: reversal by naloxone.

abstract：:Progesterone, which is normally produced in the endoplasmic reticulum, was found to be rapidly degraded in the cytosolic fraction of the guinea pig adrenal cortex in vitro. Assuming this finding reflects what happens in vivo raises a question as to the source of progesterone for interacting with a nuclear progesterone...
