Compare And Contrast Estrogen And Testosterone

Robert Sapolsky’s collection of essays “The Trouble with Testosterone” is a thorough examination of the evolutionary roots of human behavior, by discussing the biology behind it. The book contains eighteen essays that explore this issue. The Stanford neuroscientist is a great writer: he concisely explains his views in each essay and makes it funny and easy for a layman to understand and absorb. He unpacks complex scientific ideas and explains them. The essay that I found most interesting was the titular essay, which was an examination of flawed logical reasoning that biologists make when they think there is a causal relationship between testosterone and aggression. Sapolsky, in that essay, explains why that is not true. These essays did not

1. Based on the information provided about the regulation of testosterone secretion, propose a testable hypothesis to explain how trenbolone acetate caused Frank’s testicles to shrink.

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

Focusing on just natural clarifications of human conduct, the Biological Theory trusts that physiological variables tremendously affect sexual conduct. Scholars regularly take a gander at anomalous hormonal and androgenic levels in the body and cerebrum to depict freak sexual practices as in rising hormones are identified with physical changes that advance sexual excitement, climax, discharge, and other sexual movement. "In spite of the fact that a survey of natural studies indicates clashing results about the relationship between

Hormones are also associated with sexual characteristics and function at different levels from infancy to adulthood. Puberty triggers a specific gender and one will attract to the opposite sex (normally).

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

A hormone is a type of chemical messenger that allows communication between cells. Hormones are concealed by the glands of the endocrine system and they help to maintain homeostasis and to regulate reproduction and development. Glands of the endocrine system secrete hormones right into the extracellular environment. The hormones then diffuse to the bloodstream by capillaries and are transported to the target cells. Hormones are molecules that generally apply effects at sites other than that from which they were produced and secreted.

The hormonal differences in males and females include levels of oxytocin, estrogen, progesterone, testosterone, and vasopressin. Oxytocin is more functionally present in females, which assists them with bonding and maintaining relationships. The level of female hormones, estrogen and

Changes Regular changes ( happen in the bigger populace) - The basic changes are in for the most part everybody. For instance - in men sexual excitement and pre-ejaculatory are decreased with age. . The amount of maturing impacts a particular individual shifts from i on diverse factors.((Meston, C.M(1997, October).Aging and sexuality. The Western Journal of Medicine, 167(4), 285)).Some sex-related changes happen in people as a characteristic procedure.

They are also referred to as anabolic, which is used to promote growth in muscle, specifically skeletal muscle, and androgenic, which is the development of male sexual characteristics in males and females. Testosterone is the male sex hormone responsible for developmental changes during puberty, in males. They also hold an androgenic effect, which again is primary/secondary sexual characteristic changes, such as, voice changes, hair growth, genital changes and emotional effects. Testosterone also has an anabolic effect such as muscle, bone, and red blood cell growth. The way anabolic steroids work is by affecting the activation rate of the enzymes involved in protein metabolism. This is used to enhance protein synthesis and decrease the degrading of protein in the muscle, which is called an anti-catabolic

Luteinizing hormone releasing hormone (LHRH) agonists therapy may be used to enhance a negative feedback loop between the anterior pituitary and testicles, thus inhibiting the production of TST. LHRH agonists replicate the effects of endogenous luteinizing hormone which cause an acute rise in TST production — followed by a significant decrease in long term TST levels. LHRH antagonists may be used to disrupt the hypothalamic pituitary axis and inhibit the production of male sex androgens. The therapeutical index of LHRH antagonists may be greater than that of LHRH agonists because they do not cause the acute flare in TST as

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

Sherry Baker’s article “The Home Team Advantage...and Other Sex Hormone Secrets” aims to summarize the research on what different amounts of the sex hormones, testosterone and estrogen, actually do to us. Baker looks at behaviors in low-testosterone and high-testosterone males, how prenatal exposure to testosterone influences spatial reasoning, and memory capabilities in relation to estrogen levels.

Of particular interest are those chemicals, which mimic the female hormone of estrogen, which is

The endocrine system in the human body stores a chemical known as hormones. Hormones are released by endocrine glands into the bloodstream and travel throughout the body carrying messages. A hormonal impulse is similar to a nerve impulse only much slower. The messages carried by the hormones trigger different behaviors. Hormones can affect behavior in many ways such as: Mental activity or tiredness, boredom or excitement, sexual
