How is Froehlich syndrome related to other disorders?
General Discussion. Froehlich syndrome is a constellation of endocrine abnormalities believed to result from damage to the hypothalamus, a part of the brain where certain functions such as sleep cycles and body temperature are regulated. Froehlich syndrome appears to be acquired while certain other disorders that resemble it,…
What happens to teenage boys with Froelich syndrome?
Teenage boys with this disorder must be distinguished from those who have inherited growth delay disorders or Prader-Willi syndrome. Froehlich syndrome is characterized by increased or excessive eating that leads to obesity, small testes, and a delay in the onset of puberty.
Where is the hypothalamic gland located in Froelich syndrome?
The hypothalamic gland is the endocrine gland that produces substances that stimulate the pituitary and regulate appetite. In Froehlich syndrome, the front portion (anterior) of the pituitary gland fails to secrete the hormones that are necessary for the onset of normal puberty.
How is hormone replacement therapy used for Froelich syndrome?
Standard Therapies. Treatment. Pituitary extracts may be administered through hormone replacement therapy (HRT) to replace the missing hormones in patients with Froehlich syndrome. For males, this usually includes administration of human chorionic gonadotropin to reach puberty followed up by testosterone.
