Abstract

In women and men, an important proportion of estrogens and androgens are synthesized locally at their site of action in peripheral target tissues. This new field of endocrinology has been called intracrinology. In postmenopausal women, 100% of active sex steroids are synthesized in peripheral target tissues from inactive steroid precursors while, in adult men, approximately 50% of androgens are made locally in intracrine target tissues. The last and key step in the formation of all estrogens and androgens is catalyzed by members of the family of 17beta-hydroxysteroid dehydrogenases (17 beta-HSDs) while different 17 beta-HSDs inactivate these steroids in the same cell where synthesis takes place. To date, seven human 17 beta-HSDs have been cloned, sequenced and characterized. The 17 beta-HSDs provide each cell with the means of precisely controlling the intracellular concentration of each sex steroid according to local needs.

  • Peripheral tissue metabolism of steroids (intracrinology) is accepted as a key way in which tissues such as the endometrium can utilise inactive steroids present in the blood to respond to local physiological demands and fine-tune activation or inhibition of steroid hormone receptor-dependent processes.

    “Peripheral tissue metabolism of steroids (intracrinology) is now accepted as a key way in which tissues, such as the endometrium, can utilise inactive steroids present in the blood to respond to local physiological demands and ‘fine-tune’ the activation or inhibition of steroid hormone receptor-dependent processes.”
  • Supplementation with physiological amounts of exogenous DHEA permits the biosynthesis of androgens and estrogens only in target tissues that contain the specific steroidogenic enzymes.

    “supplementation with physiological amounts of exogenous DHEA permits the biosynthesis of androgens (essentially testosterone and DHT) and estrogens only in the target tissues that contain the specific steroidogenic enzymes (25,33).”
  • Women at menopause are not only deprived from estrogens because of rapid loss of ovarian activity but also have been deprived from androgens for a longer period because of progressive decrease of serum DHEA levels starting years before menopause.

    “women, at menopause, are not only deprived from estrogens because of a rapid loss of ovarian activity but also have been deprived from androgens for a longer period because of a progressive decrease of serum DHEA levels starting quite a few years before menopause.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
