Though reproductive system interactions with other body systems are relatively meager, oneâthat with the endocrine systemâ stands out and will receive the bulk of our attention. Indeed, these two systems are difficult to divorce from one another, particularly since the gonads themselves function as endocrine organs. Most other reproductive system interactions, such as those with the nervous and cardiovascular systems, are mediated through its hormones.
The endocrine system is made up of pituitary, pineal, thyroid, parathyroid and adrenal glands, pancreatic islet cells (also known as islets of Langerhans) and the ovaries or testicles. 1  The pituitary, pineal and parathyroid glands are neuroendocrine glands. Neuroendocrine cells in the digestive system regulate intestinal movements and the release of digestive enzymes. 2  Neuroendocrine cells in the respiratory system are believed to play a role in the developmental stages of the respiratory organs. 3  They also regulate respiratory function.
