THE ENTRY OF ASCORBIC ACID INTO THE CORPUS LUTEUM IN VIVO AND IN VITRO AND THE EFFECT OF LUTEINIZING HORMONE

Abstract
SUMMARY: Judged from the exchange rate between luteal and plasma ascorbic acid there appears to be no compartmentalization of ascorbic acid within the corpus luteum. Evidence is presented to show that the uptake of ascorbic acid into slices of superovulated rat ovary is an energy-dependent process which is inhibited by luteinizing hormone (LH) by means of its stimulatory effect on progesterone synthesis. The results are discussed in relation to the adrenal cortex and methods involving ascorbic acid depletion used in the assay of corticotrophin and LH.
