Pregnancy and Hormones. One of the most common causes of excessive swelling in the feet is pregnancy. During pregnancy a woman's body is filled with more blood than usual, which can cause veins to swell or leak blood into the tissues, which leads to swelling, especially in the feet. An imbalance in hormones can also lead to feet swelling.
The amount of testosterone synthesized is regulated by the hypothalamicâpituitaryâtesticular axis (see figure to the right). When testosterone levels are low, gonadotropin-releasing hormone (GnRH) is released by the hypothalamus, which in turn stimulates the pituitary gland to release FSH and LH.These latter two hormones stimulate the testis to synthesize testosterone.he amount of testosterone synthesized is regulated by the hypothalamicâpituitaryâtesticular axis (see figure to the right). When testosterone levels are low, gonadotropin-releasing hormone (GnRH) is released by the hypothalamus, which in turn stimulates the pituitary gland to release FSH and LH.
Thyrotropin-releasing hormone (TRH), also called thyrotropin-releasing factor (TRF), thyroliberin or protirelin, is a tropic, tripeptidal hormone, produced by the hypothalamus, that stimulates the release of TSH (thyroid-stimulating hormone) and prolactin from the anterior pituitary.RH is produced by the hypothalamus in medial neurons of the paraventricular nucleus. At the beginning, it is synthesized as a 242-amino acid precursor polypeptide that contains 6 copies of the sequence-Gln-His-Pro-Gly-, flanked by Lys-Arg or Arg-Arg sequences.
