Testosterone: Male Hormones

Mary Decker Mary Thereza Decker-Slaney was born on August 4th, 1958 in Flemington, New Jersey. When she was just 14 years old, she was known as “Little Mary Decker” for winning the 800m at a US-Soviet meet(The). At 15 years old she broke indoor records in the 1000 and 800

All Sexual Health Issues are Related to a Man's Overall Health 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 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

WHAT ARE STEROIDS Steroids are a form of performance enhancing drugs. People use steroids for legal medical reasons, however most users illegally inject themselves with steroids to look and feel muscular, most commonly athletes. Steroids imitate the effects of male hormone testosterone, although they also occur in women.

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

Getting the testosterone level right is critical for a man, since it effects many of their daily

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

In my life, I have gone through several situations that were certainly inevitable. Considerably, I had to teach myself that things just happen for a reason, and realize that sometimes the reason is just unknown. On November 20th, 1997, I was born in the wrong body. The biological hormones I

Hypogonadism What is hypogonadism? Hypogonadism is a medical condition characterized by reduced testosterone production in men due to either testicular failure (primary hypogonadism) or pituitary disease (secondary hypogonadism). Men may develop symptoms such as decreased sexual desire (reduced libido), erectile dysfunction, problems with ejaculation, fatigue, and anemia as a result of low testosterone levels.

Hormonal Secreation of a hormone release is dependent on the secretion of another hormone. 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.

It’s also important to understand that testosterone is the body’s natural ingredient that helps this process along. If we didn’t have testosterone in our system, then we wouldn’t be able to build as much muscle as quickly. This is why anabolic steroids are sometimes used to treat people who have testosterone deficiencies—because without it, building muscle isn’t really possible.

When an individual "comes out" as homosexual or bisexual, they most likely hear the words "well that's your choice." But for any one person who actually is homosexual, they know it's not a choice. So what makes us this way? The answers are small chemicals that control our very lives. These chemicals are the Androgens, Testosterone and Estrogen.

Although "normal" testosterone levels are defined differently in different labs, most studies define low testosterone ("hypogonadism") in men as a total testosterone of less than 300 ng/dl. In men younger than 40 years old, there may be significant differences between morning and evening levels. Blood testing should thus be conducted in
