Donno what HH is. Also don't know tha cause. I have no other issues so I'm not sure what's up. My doc didn't seem concerned enough to look into it. I also don't know what primary or secondary means in this instance. Not tryin to b smart ass just ignorant to some of tha terms
HH is Hogans Hero

- Let me give you a run down on HPTA so you understand the terminology.
HPTA stands for Hypothalamic-Pituitary-Testicular Axis. A link between 3 glands/clusters that results in testosterone and sperm production.
Hypothalamic:
This refers to the Hypothalamus. This is a small cluster in the brain that links your central nervous system to the endocrine system. This is where it all begins. Hypothalamus sends a signal out to the Pituitary gland. This signal is called Gonadotropin Releasing Hormone (GnRH). Gonadotropins are your Luteinizing Hormone (LH) and Follicle Stimulating Hormones (FSH). These are explained in the next step.
Pituitary:
This refers to the Pituitary gland in your head, just under the brain, and releases LH, FSH, and more (because it received the signal from the hypothalamus). To stay on topic, we'll just discuss LH and FSH. LH is a hormone that is sent over to the testes for the purpose of stimulating Leydig Cells to produce testosterone. FSH is another hormone sent to the testes for the purpose of sperm production, which is accomplished by joining testosterone in the stimulation of Sertoli Cells. Both LH and FSH are required as they work in synergy for the betterment of production by the testes.
Testicular (also known as Gonadal; ie HPGA):
This refers to the testes. This is where your Leydig Cells and Sertoli Cells (mentioned above) reside. These are cells that produce testosterone and sperm when stimulated by LH and FSH (which arrived because the pituitary sent them). This event completes the chain reaction that started at the Hypothalamus, and now we have testosterone and sperm production.
Low T in men is referred to as Hypogonadism. You could be primary or secondary hypogonadal. Primary would indicate a problem with the testes. Secondary would be indicative of an issue in the brain, particularly the Hypothalamus and/or Pituitary.
It's important to find out what type of hypogonadism you have. You could be restarted and no longer require therapy for many years. Have you used antidepressants often in the past?
