Primary hypogonadism (congenital or acquired): Testicular failure due to diseases and conditions in the body such as cryptorchidism, bilateral torsion, orchitis, vanishing testis syndrome, orchiectomy, Klinefelter Syndrome, chemotherapy, or toxic damage from alcohol or heavy metals; these men usually have low serum testosterone levels and gonadotropins (FSH, LH) above normal range Hypogonadotropic hypogonadism (congenital or acquired): Gonadotropin or luteinizing hormone-releasing hormone (LHRH) deficiency or pituitary-hypothalamic injury from tumors, trauma, or radiation; these men have low testosterone serum concentrations but have gonadotropins in the normal or low range.
Testosterone is a hormone that is produced in large amounts by males (and a little bit in females), in the testes and adrenal glands. High testosterone levels are associated with sexual performance, reproductive function, muscle mass, hair growth, aggressive, competitive behaviors, and other such manly things. Testosterone levels tend to peak at the age of 40, and slowly decline from there. Luckily, there are many things you can do to increase testosterone, so if you feel like your T levels could use a boost, you've come to the right place.
There is no doubt about it, in the world of anabolic androgenic steroids testosterone is king and in the human body itself it is an imperative hormone. Yes, there are side effects of testosterone use but they are manageable, largely preventable and often of no concern if were responsible. There is a very real risk to reward ratio that exist around exogenous testosterone use; the more we use the greater the reward but the more we use the greater the potential for negative or adverse side effects. Further and often overlooked, a healthy diet can greatly improve our odds; as cholesterol and blood pressure can be a concern we should consume diets that promote healthy levels of both.
