In men, it causes impaired muscle and body hair development, gynecomastia, decreased height, erectile dysfunction, and sexual difficulties. If hypogonadism is caused by a disorder of the central nervous system (e.g., a brain tumor), then this is known as central hypogonadism.
Hone Health reports that if your levels of testosterone drop below 300 ng/dL and you experience unpleasant signs of low testosterone, you officially have a medical condition known as testosterone ...
Hypergonadotropic hypogonadism (HH), also known as primary or peripheral/gonadal hypogonadism or primary gonadal failure, is a condition which is characterized by hypogonadism which is due to an impaired response of the gonads to the gonadotropins, follicle-stimulating hormone (FSH) and luteinizing hormone (LH), and in turn a lack of sex steroid production. [1]
Hypogonadism can occur through a number of different mechanisms. The use of the term hypogonadotropic relates to the fact that the hypogonadism found in HH is caused by a disruption in the production of the gonadotropin hormones normally released by the anterior pituitary gland known as luteinising hormone (LH) and follicle stimulating hormone ...
Hypogonadotropic hypogonadism (HH), is due to problems with either the hypothalamus or pituitary gland affecting the hypothalamic-pituitary-gonadal axis (HPG axis). [1] Hypothalamic disorders result from a deficiency in the release of gonadotropic releasing hormone ( GnRH ), while pituitary gland disorders are due to a deficiency in the release ...
Low testosterone can be defined as hypogonadism in people with testes. Hypogonadism in people with testes is established as the hormonal inhibition of testosterone that can either be inherited or acquired at a later stage in life. Under the circumstances of pre-pubescent hypogonadism, many sexual developmental characteristics may be altered.
The use of dynamic endocrine tests is particularly helpful in isolating a diagnosis of PAIS. [ 1 ] [ 12 ] One such test is the human chorionic gonadotropin (hCG) stimulation test. If the gonads are testes , there will be an increase in the level of serum testosterone in response to the hCG, regardless of testicular descent . [ 1 ]
For example, the male mutation of the GnRH coding gene could result in hypogonadotrophic hypogonadism. A mutation that cause a gain of function for LH receptor can result in a condition known as testotoxicosis, which cause puberty to occur between ages 2–3 years. Loss of function of LH receptors can cause male pseudohermaphroditism.
