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).

Erythropoietin is an endogenous hormone that stimulates erythropoiesis. Forms of recombinant human erythropoietin (rHuEpo) are also erythropoiesis-stimulating agents, and are mostly called epoetin; for example, epoetin alfa and beta are different isoforms of erythropoietin and the main differences in their actions arise from differences in glycation (60 E).
