Hypogonadism Testing Algorithm. Hypogonadism is one of the most common endocrine disorders in men and is characterized by low serum testosterone levels and/or low sperm counts with clinical signs and symptoms of androgen loss. Prevalence ~4-5 million men in U.S. 20% of men â¥60 years.
Diencephalon: The diencephalon, along with the telencephalon (cerebrum) comprise the two major divisions of prosencephalon (forebrain). Main structures of the diencephalon include the hypothalamus, thalamus, epithalamus (including the pineal gland), and subthalamus.The diencephalon relays sensory information between brain regions and controls many autonomic functions of the peripheral nervous system.unction: The diencephalon is involved in several functions of the body including: 1  Directing Sense Impulses Throughout the Body. 2  Autonomic Function Control. 3  Endocrine Function Control. 4  Motor Function Control. 5  Homeostasis. 6  Hearing, Vision, Smell, and Taste. 7  Touch Perception.
Function of the Thalamus and Hypothalamus. The thalamus sends and receives signals to and from the brain and body. The brain sends a signal to the thalamus, which relays the signal to the body. Similarly, the body sends a signal to the thalamus, and the thalamus relays the signal to the brain.esson summary. The diencephalon is located deep in the brain underneath the cerebrum, and it is the link between the nervous system and the endocrine system. It includes the thalamus and hypothalamus. The thalamus relays signals to and from the brain and body.
