Adrenal glands
The adrenal glands are found above the kidneys. They produce a variety of hormones, including adrenaline and the steroids aldosterone and cortisol.

The ovaries are organs in females that produce oocytes (egg cells) and secrete estrogens and progesterone.

The pancreas has a dual function as an exocrine gland that secretes digestive enzymes, and an endocrine gland that releases the hormones glucagon and insulin.

Pineal gland
The pineal gland is a pine cone-shaped structure near the center of the brain that secretes melatonin. This hormone controls biological rhythms.

Pituitary gland
The pituitary gland is located at the base of the brain. It consists of an anterior pituitary lobe and a posterior pituitary lobe. Both release pituitary hormones under control of the hypothalamus.

Males have two testes contained within the scrotum, which produce both sperm and androgens, primarily testosterone.

Thyroid gland/Parathyroid glands
The thyroid gland is a butterfly-shaped organ located in the neck. The parathyroid glands are on the back of the thyroid gland. The thyroid gland synthesizes thyroxine, triiodothyronine and calcitonin. The parathyroid glands secrete parathyroid hormone.
