Hypogonadism in males is due to the inability of the body to produce a sufficient amount of testosterone. This disease can be hereditary or can manifest after injury or infection. There are two classes of hypogonadism: primary and secondary. Primary hypogonadism is caused by a problem in the testes, while secondary hypogonadism is caused by problems in the pituitary gland or the hypothalamus. The hypothalamus is responsible for secreting gonadotropin releasing hormone (GnRH), which stimulates the pituitary gland to produce follicle stimulating hormone (FSH) and luteinizing hormone (LH). Luteinizing hormone then stimulates the tests to produce testosterone, which is important in masculine growth and secondary sexual characteristics. There are
The location of the pituitary gland is in the sella turcica of the sphenoid bone and attaches to the hypothalamus(Marieb & Hoehn 441). The Hypothalamus is included in the function of the pituitary gland as it sends chemical stimulus to it(Marieb & Hoehn 442).Part of the pituitary is called the “ master endocrine gland” due to the fact that is produces many hormones that affect the whole body(Shannon 175).This part of the pituitary gland is called the anterior pituitary(Marieb & Hoehn 601). There are six hormones that the anterior pituitary secretes normally. These Hormones are growth hormones,thyroid stimulating hormones,adrenocorticotropic hormones,luteinizing hormones,follicle stimulating hormones and prolactin hormones( Shannon 175).The Hormone prolactin is one that in normal function stimulates the act of lactation for new mothers to feed their baby(Shannon 175).
CAH is an autosomal recessive genetic disorder and males and females are affected in equal numbers. Chromosome 6 is where the group of genes lie that causes the most common forms of CAH. Adrenocorticotropic hormones (ACTH) are released by the anterior lobe in the pituitary gland. Its role is to act on cells of the adrenal cortex which then synthesizes corticosteroids and cortisol. However, those with CAH have insufficient amounts of the enzyme 21-hydroxylase, needed to convert 17-hydroxyprogesterone (17-OHP) into cortisol.
Our text describes pedophilia as a person who “gains sexual gratification by watching, touching, or engaging in sexual acts with prepubescent children, usually 13 years old or younger” (Comer, 2013, p. 411). The movie, The Woodsman describes the story of a convicted sex offender recently released from prison. Walter, depicted by Kevin Bacon shed some insight into the motivations and thought processes that a sex offender, specifically a pedophile might have.
The hormones produced from the endocrine system come from a wide range of different places. Among those responsible for hormone production are the glands and a few organs as well. The glands that are involved are the pituitary, thyroid, thymus, parathyroid, and adrenal. The organs, which also play a vital part, are the pancreas, gonads, kidneys, heart, and parts of the digestive tract. All these different glands or organs work together in the production of certain hormones. Those produced in one location will almost always have an effect on many other areas of the body, not just the surrounding tissues.
The thyroid organ, though small, impacts every cell in the body by providing metabolism regulation (endocrine web). This butterfly-shaped, endocrine organ located at the neck, secretes hormones to control the body’s metabolism - or the way the body uses energy that help the body with energy, manage heat, and help organs such as the heart and brain function properly (thyroid.org). When not functioning properly, thyroid dysfunctions occur disrupting the three points of control: the hypothalamus in the brain, the pituitary gland, and the thyroid gland. Common thyroid disorders include Hashimoto’s, Graves’ disease, thyroid disorders like hypothyroidism and hyperthyroidism, and nodules or goiters (health line).
Masters and Johnson were a pioneering team in the field of human sexuality, both in the domains of research and therapy. William Howell Masters, a gynecologist, was born in Cleveland, Ohio in 1915. Virginia Eshelman Johnson, a psychologist, was born in Springfield, Montana in 1925. To fully appreciate their contribution, it is necessary to see their work in historic context. In 1948, Alfred C. Kinsey and his co-workers, responding to a request by female students at Indiana University for more information on human sexual behavior, published the book Sexual Behavior in the Human Male. They followed this five years later with Sexual Behavior in the Human Female. These books began a revolution in social awareness of and public attention given to human sexuality. At the time, public morality severely restricted open discussion of sexuality as a human characteristic, and specific sexual practices, especially sexual behaviors that did not lead to procreation. Kinsey's books, which among other things reported findings on the frequency of various sexual practices including homosexuality, caused a furor. Some people felt that the study of sexual behavior would undermine the family structure and damage American society. It was in this climate - one of incipient efforts to break through the denial of human sexuality and considerable resistance to these efforts - that Masters and Johnson began their work. Their primary contribution has been to help define sexuality as a healthy human trait and the experience of great pleasure and deep intimacy during sex as socially acceptable goals. As a physician interested in the nature of sexuality and the sexual experience, William Masters wanted to conduct research that would lead to an objective understanding of these topics. In 1957, he hired Virgina Johnson as a research assistant to begin this research issue. Together they developed polygraph-like instruments that were designed to measure human sexual response. Using these tools, Masters and Johnson initiated a project that ultimately included direct laboratory observation and measurement of 700 men and women while they were having intercourse or masturbating. Based on the data collected in this study, they co-authored the book Human Sexual Response in 1966. In this book, they identify and describe four phases in the human sexual response cycle : excitement, plateau, orgasm, and resolution. By this point in time, the generally repressive attitude toward sexuality was beginning to lift and the book found a ready audience.
Endocrinology can be defined as the study of the structure and function of the endocrine system (Tortora & Grabowski 1996). The endocrine system is composed cells, known as endocrine cells, which are distributed around the body and produce the chemical messengers known as hormones. Following secretion by endocrine cells, hormones travel in the blood where they affect tissues outside of their tissue of origin - and are therefore a form of cellular communication. In multicellular organisms, such as humans, cellular communication is essential for a number of body processes and the maintenance of homeostasis (Campbell, N.A. et al. 2015). In this essay, I am going to outline some of a number of body
The thyroid gland is found in the front of the neck and produces two main hormones. The hormones are called thuroxine (T4) and Triiodothyronine (T3). Together these hormones regulate the body’s metabolism by increasing energy use in cells, regulate growth and development, help to maintain body temperature and aid in oxygen consumption. These two hormones are regulated by hormones produced by the hypothalamus and pituitary gland. The hypothalamus senses changes in body’s metabolic rate and releases a hormone known as thyropin-releasing hormone (TRH). This hormone then flows through connecting vessels to the pituitary gland which signals it to release another hormone. This hormone is known as thyroid-stimulating hormone (TSH). TSH then makes its way to the bloodstream until it reaches the thyroid where it is then signaled to activate T3 and T4 production [1]. This mechanism is controlled by a negative feedback loop meaning that when there is a sufficient amount of thyroid hormones in the blood stream, this will signal back to stop production of thyroid stimulating hormones. Complications occur when the thyroid hormones keep increasing even though there is already a sufficient amount of T3 and T4 in the blood stream. This process of over expression of thryroid hormones is known as hyperthyroidism. Hyperthyroidism is a general term that includes any disease that has a consequence of an overabundance of thyroid hormones. Hyperthyroidism is a general term but there are many variant diseases that are in the hyperthyroidism category. These diseases include diffuse toxic goiter, Basedow’s disease, thyrotoxicosis, Parry’s and Graves’ disease.
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.
A man has been married to his wife for seven years. The couple has two beautiful children, a fabulous home, and appear to have the perfect marriage. After the husband leaves work one afternoon, he decides to stop in at the local bar. The man sits at a table in the corner of the room. Not long after his arrival, a woman approaches him. She asks the man if she can join him at his table. The two seem to have quite a bit in common and enjoy each other’s company. The woman asks if he would like to go back to her apartment. He has not had a fight with his wife today. In fact, she surprised him with a love note in his briefcase. Their sex life is enjoyable, frequent, and without complaint. The couple is not currently having financial problems. Despite this, why did the man decide to leave with a stranger and cheat on his wife? A great deal of research has been carried out on the topic of infidelity. Marital therapists have reported that more than half of the couples they counsel are in therapy as a result of infidelity (Atkins, Jacobson citation). Therapists also consider an extramarital affair as, “one of the most damaging relationship events and one of the most difficult problems to treat in couples therapy” (whisman predicting sexual infidelity…). Some therapists estimate that 50% to 65% of couples seek help after an incident of infidelity in their relationship (Atkins, Jacobson & Baucom). Identifying the reasons for this problem are essential to the success of its reduction. Infidelity is not a new phenomenon. However, there was little research on the topic until the late 1970’s (Drigotas & Barta, 2001). Numerous factors have been examined while trying to determine the root cause for extramarital relationships a...
Hyper Sexual addiction is a disorder that can be defined as a person having a habitually elevated sex drive, fantasies, and urges. Nevertheless, compared to other sexual addictions, this could be known as one of the most riskiest and dangerous addiction. Hyper Sexual Addiction has become more prevalent because of the infidelities amongst some celebrities and political figures. Sexual addiction has always existed, but because of technology and social media, people have become more aware of it. People who suffer from this disorder are like drug addicts that crave drugs; they think they can stop, but the urges are constantly there. According to An Elements Behavioral Health article (2016), for the sex addict, sexual activity provides an intense,

The thyroid gland is part of the endocrine system, and it is controlled by the pituitary which is known as the “master gland” of the endocrine system. The pituitary controls the thyroid by producing Thyroid Stimulating Hormone (TSH) which stimulates the production of thyroid hormones. . The thyroid gland secretes two main hormones: Thyroxine (T4) and Tri-Iodothyronine (T3). These hormones increase metabolic rate, heat production, oxygen consumption, appetite, growth hormone secretion, alertness and quicker reflexes. The thyroid gland is located in the anterior portion of the neck, beneath the Adam’s apple. It is divided in two lobes on either side of the windpipe: right lobe and left lobe. These lobes create what looks like a butterfly shape. The gland is essential to the contribution of maintaining the homeostasis of the body. It plays a role in monitoring the body’s expenditure of energy and running the body’s metabolism.
Men and women sexually go through a cycle. This cycle is known as the sexual response cycle. The sexual response cycle is made up of four different phases, the excitement, plateau, orgasm, and resolution phases. The cycle is also categorized in two ways, vasocongestion and myotonia. Vasocongestion is where swelling occurs because blood rushes to certain areas of the body such as earlobes, for women to the opening of the vaginal area, and for men around the testes, it also causes the erection of the penis. Myotonia is what causes hands and feet to spasm, affects the face, and the involuntary movements of orgasm, these occur because the muscles are tightening creating these movements and spasms to occur. (Nevid & Ruthus, 2005).
There are many enzyme-catalyzed reactions that occur in cells through control mechanisms, which keep humans in chemical balance. There are two systems that have a major responsibility for regulating body chemistry known as the endocrine system and nervous system. The endocrine system depends on chemical messengers that flow in the bloodstream known as hormones. Hormones travel to target cells, where they connect with receptors that initiate chemical changes within cells. The nervous system depends on neurotransmitters that are electrical impulses in nerve cells activated by its own chemical messengers. The nervous system counts on a much faster means of circulation. This cycle is what allows drugs to work so well, because they mimic the crucial role of hormones and neurotransmitters in the function of the human body.
