Steroids
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 in the male is produced mainly in the testis, an a small amount is being produced in the adrenal. It is synthesized from cholesterol. The regulation of its production may be simplified which means the hypothalamus (part of the brain) produces gonadotrophin releasing hormone which acts on the anterior pituitary to increase the production of luteinizing hormone and follicle stimulating hormone. The luteinizing hormone acts on the Leydig cells in the testes, causing them to produce testosterone. The follicle-stimulating hormone with testosterone acts on the Sertoli cells in the testes to regulate the production and maturation of the spermatozoa. Testosterone in turn acts on the hypothalamus and anterior pituitary to suppress the production of gonadotrophin releasing hormone, follicle-stimulating hormone, and the luteinizing hormone producing a negative-feedback mechanism. This keeps everything well regulated. The small amount produced in the adrenal (in both sexes) is regulated by secretion of adrenal corticotrophin hormone, also secreted by the pituitary.
Testosterone, and its metabolites such as dihydrotestosterone, act in many parts of the body, producing the secondary sexual characteristics of then male: balding, facial and body hair, deep voice, greater muscle bulk, thicker skin, and genital maturity. At puberty it produces acne, the growth spurt and the enlargement of the penis and testes as well as causing the fusion of the epiphyses bringing growth in height to an end. It plays some role in maintaining the sexual organs in the adult, but only a low concentration is required for this.
The normal production of testosterone in the adult male is 4 to 9mg per day. The normal plasma concentration is 22.5nmol/l, of which 97% is pro...

...h blood pressure, other cardiovascular diseases, baldness, stunted growth in adolescents, and enlargement of pre existing prostate tumors can persist even after steroid use has stopped. Female steroid users, in addition to the problems listed above, can have virilizing (masculinizing) symptoms when using the harsher, androgenic compounds, including amenorrhea (which is reversible), clitoral hypertrophy, deeper voice, excessive growth of body hair, loss of scalp hair and alterations in skin texture (which frequently aren't reversible). Not all of these conditions are caused by all anabolic steroids. Some of the harsher anabolic steroids will only cause these problems for a certain percentage of the users, above certain dosages. Some of the milder anabolic steroids cause almost none of these side effects. There fore, it is a mistake to state that all steroid users will come down with these side effects. Any such silly statements will be readily flamed on m.f.w. Most of the side effects of steroid use result from the conversion of testosterone to estrogen or dihydrotestosterone. Some anabolic steroids do not undergo this conversion. These steroids will have fewer side effects.
In A Separate Peace, the main characters are foils of one another. The plot is pushed along by the changing dynamics of their friendship. Their relationship begins to drift apart when their personalities clash. The changing dynamics of Gene and Finny's relationship and the revelations in Gene's personality are what move the plot along.
In the novel, A Separate Peace by John Knowles, the protagonist Gene Forrester constantly battles within himself to find the true emotion towards his friend Phineas and to find out who he really is. Gene and Phineas formed an illusion of companionship, but there was always a silent rivalry between them in Gene’s mind. In the beginning, Gene thought his feeling towards Phineas was completely normal and it will go away in time. However, as the time went on and Gene matured he found out that his feeling was much more than little jealousy but it has turned into hate. Gene Forrester develops into a mature adult when he finally accepts his feeling and faces reality.
The book "A Separate Peace" contained many different and unusual, yet original relationships between the many characters in the book. There are many exciting and emotional relationships that occur in "A Separate Peace" which help the boys grow into responsible men, such as the relationships between Gene and Finny and Leper and Gene. Gene had a friendly relationship with almost everyone at school. Everyone tried to be friends with everyone else, but usually that relationship was not real or one-sided. They would all act nicely toward people to their face, but when they would leave, they would talk about them badly and behind their backs. They would never have enough courage to stand up for their beliefs and express their feelings. They were scared of being rejected.
The problems with performance enhancing drugs are that they give the user unfair advantages over other athletes and come with many health risks such as baldness. Steroid use can result in very substantial legal consequences and can ruin the user’s reputation. There are many alternatives to steroids but not all of them are safe. Different organizations have different rules on steroids, but in most cases, the user can get suspended, fined, or even both. Various types of steroids can have various short-term or long-term side effects. There are several types of steroids, the most popular ones being anabolic steroids. Historically, steroids have been around for many years, but the debate surrounding them started recently, more specifically a few decades ago. An important term to know is anabolic steroids which are made to work with the user’s muscle mass. Another term to know is clarified by Ida Walker, author of the book, Steroids: Pumped Up and Dangerous, published by Mason Crest Publishers in 2008, defines, peliosis hepatis is a rare condition in which cysts filled with blood form in the liver, if the cysts were to pop then internal bleeding would occur. A positive argument about steroids is stated by Adrianne Blue, author of the essay, “Performance Enhancing Drugs Should Be Legal,” published in the book Athletes and Drug Use, published in 2009, disputes, “Blue concludes that legalizing performance- enhancing drugs can protect athletes from dangerously abusing them.” The utilization of performance enhancing drugs has left a giant scar on sports and has compromised the achievements of many athletes; therefore, they are transforming the sports world into a drug filled world.
Steroids are used daily in America in body building, medicine, and food production. There are three main types of steroids, Corticosteroids, Anabolic steroids, and hormone steroids. Corticosteroids are the kind of steroids doctors prescribe to patients when they are sick or have some kind of medical issue. These steroids reduce overactive immune responses and reduce swelling. Anabolic steroids are used for building muscle. They also contain a lot of testosterone. Testosterone is naturally produced by one's body but too much can cause a vast variety of problems. Hormone steroids are the steroids people put in animals (DeNoon).
Several effects of steroid use have been identified. These include an increase in low density lipoprotein (LDL) cholesterol and a decrease in high density lipoprotein (HDL) cholesterol. These lipid changes if allowed to continue over long periods of time could result in coronary heart disease (6). Some other side effects of steroids in men include shrinking of the testicles; reduced sperm count, infertility, baldness, development of breasts, and increased risk of pro...
"Anabolic steroids is the familiar name for synthetic substances related to the male sex hormones (e.g., testosterone). They promote the growth of skeletal muscle (anabolic effects) and the development of male sexual characteristics (androgenic effects) in both males and females”(National Institute on Drug Base).First, the benefits of steroids are very obvious to see. The user gains strength, mass, and speed in a short amount of time. Also, the user has a more aggressive attitude, which is good for football players. However, there are more bad side effects than good.
The testes produce sperm and sex hormones, testosterone. Surrounding each testis is a coiled tube called the epididymis, which collects and stores sperm, very much similar to that of a human. Before ejaculation a seminal fluid is added by the seminal vesicles, to prevent the sperm from drying out.
While the effects of steroids can seem desirable at first, there are serious side effects. Excessive use can cause a harmful imbalance in the body's normal hormonal balance and body chemistry. Heart attacks, water retention leading to high blood pressure and stroke, and liver and kidney tumors all are possible. Young people may develop and a halting of bone growth. Males may experience shrinking testicles, falling sperm counts, and enlarged prostates. Women frequently show signs of masculinity and may be at higher risk for certain types of and the possibility of birth defects in their children. The psychological effects of steroid use are also alarming: drastic mood swings, inability to sleep, and feelings of hostility. Steroids may also be psychologically addictive. Once started, users, particularly athletes, enjoy the physical "benefits" of increased size, strength, and endurance so much that they are reluctant to stop even when told about the risks. Major athletic competitions, including the Olympics, routinely screen athletes to prevent steroid use.
Over one million American seek short cuts to larger muscles and greater endurance with anabolic steroids and other performance enhancing drugs. Steroids are drugs that act like chemical in the body. Most steroids are transformed into testosterone when they enter the body. Testosterone is a male growth hormone. While user may gain short-term results, they are seriously shortchanging their health (Kalawalski 13-15).

“Steroids are any type of a large group of fat-soluble organic compounds, as the sterols, bile acids, and sex hormones most of which have specific physiological action” (Dictionary.com). When our bodies are still developing, the effects of steroids can be dangerous and can also be permanent (“Above”). Steroids are made out of substances such as nandrolone, stanozolol, testosterone, fluoxymestrone, and oxandrolone. Sometimes people say when you can’t pronounce something, you probably shouldn’t use it. In the 1940’s testosterone began to be widely used in competitive sports, but the dangers of loading up on testosterone were not yet clear (“History”). Instead of using steroids for a bad reason, there is a medicinal purpose. Cortisteroids can treat arthritis, asthma, lupus and multiple sclerosis, eczema and rashes, and some types of cancer (“Steroids: Medline”). Also, steroids can be used to treat anemia, to improve weight loss due to severe illness, and to treat osteoporosis. Steroids can only be sold to you by a pharmacist f...
Steroids can have many health effects on your body. Many doctors say not to use steroids because of the possible long term effects. A source from a reputable website says, “It is speculated that possible long-term effects may include adverse cardiovascular ef...
Steroids increase the rate of protein synthesis within the cells. Athletes use anabolic steroids; Anabolic steroids resemble androgenic hormones such as testosterone (2). These steroids enhance weight gain, speed, power, and aggressiveness. The intake of anabolic steroids induces an increase in muscle size by both hypertrophy and the formation of new muscle fibers (1). Anabolic steroids have an androgenic and anabolic effects, which are essentially the male hormone testosterone. Androgenic eff...
The male reproductive system is a set of organs that works together to produce sperm which will later in life fertilize females eggs. The testes are the most important part of the system because it produces sperm cells. It is similar and looks similar to ovaries of a female’s reproductive system because it also holds what they need to reproduce. Its job is to produce the sperm cells needed to reproduce. Due to hormonal imbalances the production of sperm cells may not even be possible in some males. Testosterone is the male the hormone that gives men there manly characteristics. It is made up of hydrogen, carbon, and oxygen with a white color. In the male body it helps develop sex organs, a deeper voice, and facial hair (Khalid, 2013). Cancer or a genetic disorder in males is the most common thing that cause the reductions of testosterone production in the body. Behind the testes is the epididymis which lets sperm go through the vas deferens from the testes (Dictionary, 2014). It looks like leach the way it is position right on the testes but it is thinner. When sperm is produces the ...
