The human brain at that age is still growing and has an amazing ability to recover and heal. But I am not sure if you will cause lasting damage during this growth period (until you are 25) if you are messing with your hormone levels. That question must be asked of a neurosurgeon who...
anabolic steroid- any of a group of synthetic steroid hormones used to stimulate muscle and bone growth; more than 100 have been developed and each requires a prescription to be used legally in the United States; sometimes used illicitly by athletes to increase their strength ...
What are the main sex hormones that affect men’s health? LH and FSH are hormones produced by the pituitary gland in the brain. These hormones play a role in male fertility. Testosterone is the main male sex hormone that impacts sex drive (libido), fertility, muscle mass, energy levels an...
Name three hormones that regulate bone growth in humans. List hormones in the class Steroids and include what gland or structure they are produced from. Name and describe the differences between the method of action of hormones that are lipid soluble vs. those that are not. List which class(...
and bone marrow. They also indirectly affect other organ systems by changing the immune response (e.g., bone, cardiovascular, CNS, and others). The basic and secondary immune organs are both significantly impacted by sex hormones. Sex hormones control the growth of the adult thymus as well as...
Given that sex hormones play crucial roles in the reproductive maturity and the development of extra-reproductive systems (e.g., bone, brain, and cardiovascular), exposure to any xenobiotics that can interrupt the homeostasis of sex hormones during peripubertal period could affect the health of ...
The progesterone receptors (PR-A and B) appear to be responsible for smooth muscle growth. Animal studies show that progesterone reduces coronary vasospasm. In women with exercise-induced ischemia on stress testing, addition of progesterone increases exercise time, confirming the vasodilatory effect of...
The mechanisms by which thyroid hormones affect bone are poorly defined, but the presence of thyroid hormone receptors on bone cells suggests that their actions may be directly mediated. Thyrotoxicosis is associated with bone loss and increased risk for fracture at the hip and possibly other sites;...
Testosterone and its derivatives have been shown to interact with the AR to activate genomic and non-genomic pathways that affect a wide variety of body tissues. The evidence presented in this review indicates a variety of conditions that may be correlated with and possibly caused by low levels ...
Sex hormones impact a number of aspects of immunity. As a result of the aging process, dramatic changes occur in the endocrine system, particularly in the sex hormones. Thus, it is possible that the hormonal environment may play a role in the effects of aging on normal aspects of the aging...
