sex organs

In addition to producing gametes, the female ovaries and male testes also secrete hormones. These hormones are called sex hormones. The secretion of sex hormones by the gonads is controlled by pituitary gland hormones such as FSH and LH. While both sexes make some of each of the hormones, typically male testes secrete primarily androgen's including testosterone.

Later in life Men have a decrease in testosterone and may need supplements or a combination of eating right and going to the gym regularly. I find that for me running three miles a week and eating healthy gives me more of a sex drive. I recommend not taking steroidal hormones that aren't FDA approved because long term effects are not known.

Pancreas

This organ has two functions. It serves as a ducted gland, secreting digestive enzymes into the small intestine. The pancreas also serves as a ductless gland in that the islets of Langerhans secrete insulin and glucagon to regulate the blood sugar level. The islet cells secrete glucagon, which tells the liver to take carbohydrate out of storage to raise a low blood sugar level.
I have been tested once for diabetes and my doctor had to put me on a better diet then I was on. The doctor originally though my body wasn't producing enough insulin which would cause diabetes. So lucky for me I don't have diabetes because I exercise often and eat healthier.

Thyroid hormones regulate metabolism, therefore body temperature and weight. The thyroid hormones contain iodine, which the thyroid needs in order to manufacture these hormones. If a person lacks iodine in his/her diet, the thyroid cannot make the hormones, causing a deficiency. In response to the body’s feedback loops calling for more thyroid hormones, the thyroid gland then enlarges to attempt to compensate (The body’s plan here is if it’s bigger it can make more, but that doesn’t help if there isn’t enough iodine.). This disorder is called goiter.
I have always been a seafood person and since I dont live on the cost I have to make sure I get enough tuna, lobster, and seaweed in my diet to avoid the above disorder called goiter. Once the government added iodine to our salts this has alleviated many problems.
