Where is estrogen produced post menopause




















Instead, it is produced in a number of extragonadal sites and acts locally at these sites as a paracrine or even intracrine factor. These sites include the mesenchymal cells of adipose tissue including that of the breast, osteoblasts and chondrocytes of bone, the vascular endothelium and aortic smooth muscle cells, and numerous sites in the brain.

Thus, circulating levels of estrogens in postmenopausal women and in men are not the drivers of estrogen action, they are reactive rather than proactive. This is because in these cases circulating estrogen originates in the extragonadal sites where it acts locally, and if it escapes local metabolism then it enters the circulation. This process is experimental and the keywords may be updated as the learning algorithm improves.

Stimulates growth of breast tissue Maintains vaginal blood flow and lubrication Causes lining of the uterus to thicken during the menstrual cycle Keeps vaginal lining elastic Many other functions, including preserving bone.

Prepares lining of the uterus for a fertilized egg and helps maintain early pregnancy. How do menopause and age affect this hormone? During perimenopause, levels fluctuate and become unpredictable. Eventually, production falls to a very low level.
