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.
The arousal does not need to be great, as testosterone increases are seen even after social interaction with attractive females. After a 5 minute conversation with an attractive woman, male testosterone levels can increase up to 30% from baseline (relative to an increase of 13% for conversing with males). This degree of testosterone increase is unlikely to exert any anabolic effect on muscle tissue, but can contribute to neurology.
