Clinical Trial Regulation and Phases
Addison’s Disease Diagnosis
Exams and Tests to Figure Out If You Have Addison’s Disease

An Overview of the Testes
Testes secrete the male hormone testosterone
The testes are twin endocrine glands that release testosterone, a hormone necessary for the normal development of male physical characteristics, such as muscle mass and hair growth. This article overviews testes function in the endocrine system.
An Overview of the Pineal Gland
Maintaining Circadian Rhythym
The pineal gland is the most mysterious organ in the endocrine system. It is influenced by light and produces the hormone melatonin, which affects your circadian rhythm and sleep cycles.
An Overview of the Thymus
The Gland that Protects You Long after It’s Gone

An Overview of the Ovaries
Estrogen, Progesterone, and Reproduction
The ovaries play a vital role in not only the reproductive system but also the endocrine system. Their main hormones—estrogen and progesterone—ensure proper female development and fertility. This article also summarizes ovarian diseases.
An Overview of the Hypothalamus
The Endocrine System’s Link to the Nervous System
The hypothalamus helps maintain your internal balance by regulating many of the body’s key processes, such as heart rate and body temperature. It also controls some hormones of the pituitary gland to ensure that the body functions properly.
An Overview of the Adrenal Glands
Beyond Fight or Flight
The adrenal glands secrete adrenaline to help your body respond to stress, but they also regulate many vital processes in your body, such as metabolism.
About the Endocrine System
Endocrine Glands and Hormones
The endocrine system helps your body properly function by communicating and coordinating vital processes via hormones. Hormones are produced and released by specific glands and are delivered through the bloodstream. Article is an endocrine overview.
