Essay on The Effects of Testosterone and Steroids

One of the biomarker for overtraining is the hormone testosterone (Wyatt, Donaldson, & Brown, 2013). Normally testosterone is marker of anabolic status and accelerates growth in tissues and blood flow. Testosterone also interacts with the metabolic system and stimulates protein synthesis and red cell production (Wyatt et al., 2013). Overtraining can reduce testosterone, which may cause a reduction in protein synthesis, decrease red blood cell production, and delay overall recovery. Many metabolic changes are linked to reduced substrate availability, which suggests an over-reliance on the gluconeogenic process (Wyatt et al.,

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

In some cells it produces difficulties such as changed lipid metabolism specifically in the liver, while in other is produced as demanded cells to increase the muscle size. Training or exercise along with proper nutrition is needed to build large muscles and make sure that fats do not increase in large amount. Steroids are taken in pill form or through injection. They stimulate particular proteins which are involved in the building of muscle tissue. The side effects of steroids, without a proper medicine or doctor's prescription, are: cancer, liver tumors, high blood pressure, increased risk of heart attack, and extreme acne.

a family of hormones that include the natural male hormone testosterone… These hormones have anabolic (“muscle building”) and androgenic (“masculinizing”) effects, resulting in increased muscle strength and athletic performance, at times beyond what could be attained naturally (7).

    Anabolic-androgenic steroids are a group of hormones, which includes the natural male hormone, testosterone, and a number of synthetic compounds. "Anabolic" refers to muscle building, while "androgenic" refers to increased masculine characteristics. Anabolic effects are basically muscle growth. Androgenic effects produce secondary male sex characteristics like facial hair, body hair, deepening of the voice, and so on. In the 1950's scientists were trying to isolate the muscle building properties without the masculinizing effects. This lead to the development of synthetic anabolic steroids.

Testosterone exerts effects as androgenic and anabolic in an extensive variety of target tissues, including the reproductive system, the central nerve system, anterior pituitary gland, kidney, liver, muscles and heart (Hebert et al., 1984; Shahidi, 2001; Sinha-Hikim et al., 2002). The Androgenic effects are responsible for the growth of the male reproductive tract and development of secondary sexual characteristics, while the anabolic effects stimulate nitrogen fixation and increase protein synthesis (Shahidi, 2001). The anabolic activity of testosterone and its derivatives is manifested primarily in your mycotrophic action, resulting in an increase to muscle mass by increasing the protein synthesis in the muscle (Kam, Yarrow, 2005) and by controlling body fat levels.

These are lipids (fat-soluble chemicals) produced naturally by the human body. Some of these steroids include the male hormone testosterone (an androgen) and the female hormones estrogen and progesterone. Testosterone is responsible for many of the physical changes that occur to males during adolescence, such as deepening of the voice and increase in muscle mass. Even after adolescence, testosterone continues to influence a variety of male sexual and emotional processes.

Testosterone is a hormone required for male development and sexual function. It is also responsible for building muscle mass, sperm production, and sex drive. Testosterone also influences male pattern fat distribution, bone density, and red blood cell production. The normal developing male peaks at his testosterone level during early adulthood. Once he has reached the age of 30, testosterone decease at approximately 1% per year.

Jessica’s focus, testosterone replacement therapy, is intended for men who have a medical condition called hypogonadism, in which the body does not produce enough testosterone due to injury or disease. However, direct-to-consumer marketing campaigns push products such as AndroGel, Testim, and Axiron, claiming a condition known as “Low T,” or low testosterone, could cause men to experience symptoms such as low libido, muscle loss and weight gain. But a drop in testosterone levels is a natural part of aging in men. Testosterone supplements are designed not for age-associated declines

Testosterone is a hormone that is quite predominant in men. It is because of this hormone that a man can act sexually and perform well in life. This hormone helps a lot in the body growth and the muscle-building of the human being. It is primarily responsible for reproduction and creating an urge for sex in men. Thus it is very important that one has adequate quantities of this hormone in the body. Some men take this hormone externally when they feel that their body is unable to produce the hormone in the right quantities. It is during this time that they take the testosterone boosters and improve the body's capability to perform. Most bodybuilders take this booster for their muscle growth. This supplement helps in stimulating the physical growth of the individual specially men. The only disadvantage of this supplement is that it leads to the growth of characteristics like excess hair on the face, body, and also leads to voice cracking. All this is attributed to the male hormone testosterone and the one who do not have it has to take in the booster dose for better growth.

It has long been known that hormones in the body can have biological as well as behavioral effects on animals. Hormones can stimulate animals to grow, regulate, and differentiate as well as press them to exhibit a wide variety of behaviors for an even broader scope of reasons. Perhaps no other hormone has gained the public notoriety of testosterone. Long considered a masculine hormone, testosterone is inextricably coupled in the minds of the public as the hormone that makes men tick. To its effects are attributed all things manly, from muscle and hair growth to aggression to an unwillingness to ask for directions. But what are the true effects of testosterone on the body, and are they different in humans as compared to other

Thus, the excess of FFAs contributes to the development of hyperglycemia and hyperinsulinemia. In addition, adipocytes of visceral adipose tissue contain large amount of β3-adrenergic receptors, corticosteroids, androgen receptors, and conversely, a relatively small number of insulin receptors and α2-adrenoceptors. Consequently, the visceral adipose tissue has a high sensitivity to catecholamines lipolytic action and low sensitivity to antilipolytic effects of insulin. On the background of estradiol deficiency and hyperinsulinemia, levels of sex hormone binding globulin (SHBG), which binds testosterone, decreases. As a result, increased concentrations of free testosterone and insulin growth factor-I,-II (IGF-I, IGF-II) can be found in the blood (Figure 1)

Anabolic steroids are synthetic derivatives of the male hormone testosterone. Most healthy males produce 2-10 milligrams per day of testosterone. Testosterone is responsible for

The participants were divided into four groups: those given a placebo with or without weight training, and those given 600-mg testosterone enanthate with or without weight training. Diet and training times were controlled. Fat-free mass, muscle size and strength increased more than placebo in both groups taking testosterone than in the groups taking placebo. The subjects in the exercise plus testosterone group had a 9 percent increase in mass and 23 percent increase in bench-press strength, compared with 3 percent and 9 percent, respectively, in the subjects in the exercise plus placebo group.6 These doses were comparable with the doses that many athletes who use steroids take.

However, we can also see that, in a reversal of roles, that males possess a higher quantity of muscle mass. This is due to the fact that males naturally produce a higher amount of the hormone known as testosterone, even though it can still be produced by the females. Testosterone is a hormone that not only helps both muscle growth and development (or repair), but also helps develop a male’s sexual characteristics.
