Testosterone: Male Hormones

While it is common for many sexual dysfunctions to be related to a medical condition, it is not true one hundred percent of the time. Certain sexual health issues, such as premature ejaculation, can be tied to an underlying medical malady, such as obesity. Yet, there are many men across the world who deal with premature ejaculation, erectile dysfunction, and delayed ejaculation who are otherwise perfectly healthy. This is not to say that the men in question

Testosterone is released from the leydig cells and circulates the body. Like estrogen, testosterone can enter the target cell, bypassing the cell membrane and is transported to the nucleus by a carrier protein. Testosterone is also a transcription factor in which testosterone binds to genes and influences the function. Depending on the type of cell, testosterone can be converted into another form before reaching the nucleus. Only about seven percent of circulating testosterone is converted to dihydrotestosterone (DHT) and less than one percent is converted to estrogen. Testosterone first takes effect in the womb, allowing male reproductive organs to differentiate from female organs. The presence or absence of testosterone determines whether a baby will be male or female. At the onset of maturity, testosterone also signals other cells in the testes to begin production of sperm. Secondary sex characteristics include hair distribution on the face and body, the deepening of the voice as testosterone causes a growth in the larynx, induced male pattern fat distribution, bone growth, increase in sex drive and behavior. The hypothalamus regulates the amount of testosterone circulating the body by releasing follicle stimulating hormone and luteinizing hormone (Nieschlag, Behre, and Nieschlag, 2012). Testosterone utilizes a negative feedback loop by acting upon the hypothalamus to inhibit GnRH release and on the pituitary

Testosterone is a hormone in both men and women, but in greater extent in the men, testosterone is a chemical compound (C19H28O2) and is responsible for the characteristic of men such as, sexual characteristics/sexual organs, deepening of the voice, and facial and body hair. (Neil Schlager, Jayne Weisblatt, and David E. Newton 2006) Testosterone/Steroids has bodybuilding and masculinizing effect as well as treating a variety of medical conditions, like asthma, the steroid is used in a puffer, they can be used for anabolic or androgenic purposes and made for synthetic purposes making them illegal. (BROWER, K. J. 2001) Many athletes will use these to gain an advantage on competitors, with lean muscle and higher endurance, with many uses, there

Testosterone belongs to a class of male hormones called androgens that is vital for sexual and reproductive development. The National Institutes of Health regards “testosterone as the most important male hormone”(Rettner). Although the primary role of testosterone directly relates to males, women also produce testosterone at lower levels. Women’s total levels are about a “tenth to a twentieth of men’s levels”(Rettner). According to the Mayo Clinic, this hormone plays a role in sex drive, sperm production, fat distribution, red cell production, and maintenance of muscle strength and

Testosterone is a hormone that plays a vital role in men's health. Over time, or through various conditions, the testicular ability to produce testosterone levels declines, or fails, leaving men with lower than optimal testosterone levels. Testosterone gels for men, natural testosterone boosters, injections and patches are available to treat low levels.

Testosterone in the male is produced mainly in the testes and a small amount is

Anabolic-androgenic steroid is a family of lipophilic hormone that derived from cholesterol, which includes the natural male hormone testosterone and its synthetic derivatives, such as nandrolone and androsterone (Janjic et al. 2012; Basile et al. 2013). Testosterone is the principle molecule that possesses both anabolic and androgenic properties, which semantically refers to the ability to stimulate the synthesis of complex biological molecules and the growth of masculine characteristics respectively (Quan et al. 2011). The supplement of testosterone has been used in medicine as an effective treatment of hypogonadism or severe muscle catabolism since its discovery. However, due to the poor efficacy in the form of oral medication and

One of the most obvious physical changes is hair growth. I have had a significant increase in the amount of hair on my face, chest, abdomen, arms, and legs. The hair has darkened as well as gotten coarse. My skin also feels rougher, and I have experienced some acne as a outcome of that. Being that Testosterone has the ability to thicken your vocal chords, My Voice has Deepened tremendously. I have also noticed a difference in the way my body is shaped as well. Testosterone redistributes the fat in the body, and it has made me look more masculine. For example, my shoulders have broad out, and it makes me appear taller. Although these changes did not take place overnight, they certainly have made an incredible impact on the way I see

Gonadotropin is released from the hypothalamus. It travels through the hyposeal tract into the anterior pituitary lobe. The anterior pituitary lobe is stimulated by gonadotropin to release follicle-stimulating hormones (FSH) and lutenising hormones (LH) into the blood to stimulate the gonads to produce sex steroids such as testosterone. Growth hormones also operate using this mechanism.

Whatever the cause, adult onset low testosterone may be associated with fatigue, reduced interest in sex, less frequent spontaneous erections, and loss of muscle strength. Fatigue is the most common symptom.

Hormones affect our bodies more than we could ever think. In the 1730’s the voice of a grown man by the name of Farinelli an opera singer caught the attention of many. He was castrated before puberty in order to maintain his voice. When a boy reaches puberty his voice changes but Farinelli’s didn’t because of this castration. Castration is the removal of the testes. A lot of people would ask how the testes could affect so many different parts of the body. Arnold Berthold did an experiment on chickens to see how castration changes the body. He wanted to see if he could hold or reverse the effects of castration. He took the testes from cockerels and transplanted them in the abdomen of other cockerels. Surprisingly it showed that it would maintain their sexual activity and their aggressive behavior, this is how Berthold answer the question of how the testicles could affect other parts of the body. This showed that whatever was happening was happening through the blood. We now know that his finding were the release of testosterone from the testicles. Then came along the experiment of Brown Sequard, a scientist that thought he had found a method on how to rejuvenate old men. He mixed together blood of the testicular veins, semen and juice

Helps maintain testosterone levels: Testosterone is a key factor when considering the development of one’s organs and muscles. If the testosterone level is not optimum, it can lead to various problems such as improper development of bones and muscles, skin diseases, lack of immunity against diseases and much more.

Steroids imitate the effects of male hormone testosterone, although they also occur in women. There are two effects on the body caused by testosterone which are anabolic and androgenic. Anabolic effects stimulate muscle growth, instant recovery from injury and thicker bones. Androgenic effects creates and develops masculine characteristics, including facial hairs, testicles, deeper voice and muscle mass. These effects still occur naturally in women but not in such large amounts as men. Men and women often

Testosterone was often referred to as the "male hormone", It is responsible for the development of the male characteristics such as lowering of the voice, hair growth, and because the male body produces much more of it than the female. However, it is responsible for stimulating quite a few other processes. Steroids are a very large class of compounds, which occur in all animalsalso. The steroids used by athletes are mostly androgenic steroids: steroids, which act like testosterone. These steroids are used to treat inflammatory disorders such as cortico steroids, which do not have anabolic effects.

Testosterone and estrogen hormone handle the growth and maintenance of sexual characteristics in males and females. Testosterone controls male features like muscle mass and hair. On the other hand, estrogen is responsible for feminine attributes such as growth of breasts.
