Males also have the hormone estrogen. Estrogen menlarges breast size. Women have more of it, so they have bigger breasts. They also have luteniezing hormone which produces milk for mammary glans after giving birth. Men do not have that. Women displaying male qualities like beards have an excess of testoserone and androgen

When the egg and the spermatozoid unit, a zygote if formed.  That zygote begin to develop, neither as male or female.  Or should I say it develops as DEFAULT which is, female.  At 6 weeks of gestation, the zygote becomes an embryo and THEN, and only then, it differenciate to male or female.  \n\nAs you may know, female have XX chromosome and male have XY chromosome.  On that tiny Y chromosome there's a gene, called SRY, that tells the embryo's body to produce testicules.  If the embryo's female, then the second X commands the formation of ovaries.  Then hormones are produced, and penis or uterus appear.\n\nYour nipples are simply made before that 6th week, when the zygote is a "default female" and once they're there, they stay there, even after the testosterone hormone start being produced.

a steroid hormone needed for differentiation of males and females (organs, voice, hair, muscle development...) \nIt is in higher levels in men because not as much is changed into estrogen as it is for women.

It is made by the testes, ovaries and adrenal glands in adult.  In the embryo, it is made by the primitive gonadal streak, IIRC; I may have the name wrong.  That sets up a positive feedback loop, that makes the gonads turn into testes instead of ovaries.\n\nTestes make a lot more T than ovaries do, so once they form, you are heading to be a male!\n\nIf the adrenals malfunction, making too much T, you end up as "intersex"; your secondary sexual characteristics will be intermediate between male + female.\n\nAfter menopause, women get by on even less T that we do in our reproductive years, with some nasty effects... :-(\n\nFat makes some oestrogen; we do not just get oestrogen from our ovaries and adrenals.  I am not sure if fat can make T.\n\nThe steroid hormones do inter - convert a bit in the body; they are very similar, chemically, and all derive from cholesterol.

Function\nLike the ovaries (to which they are homologous), testicles are components of both the reproductive system (being gonads) and the endocrine system (being endocrine glands). The respective functions of the testicles are:\n\nproducing sperm (spermatozoa) \nproducing male sex hormones, of which testosterone is the best-known \nBoth functions of the testicle, sperm-forming and endocrine, are under control of gonadotropic hormones produced by the anterior pituitary:\n\nluteinizing hormone (LH) \nfollicle-stimulating hormone (FSH) \nStructure\nUnder a tough fibrous shell, the tunica albuginea, the testis contains very fine coiled tubes called the seminiferous tubules. The tubes are lined with a layer of cells that, from puberty into old-age, produce sperm cells. The sperm travel from the seminiferous tubules to the rete testis, the efferent ducts, and then to the epididymis where newly-created sperm cells mature (see spermatogenesis). The sperm move into the vas deferens (also called the ductus deferens), which opens into the urethra. Upon any sufficient sexual arousal, the sperm cells move through the ejaculatory duct and into the prostatic urethra, where the prostate, through muscular contractions, ejaculates the sperm, mixed with other fluids, out through the penis.\n\nThe genital anatomy described here, along with the neuroanatomy and hormonal systems that enable it to perform ejaculation, have as primary evolutionary functions the impregnation of a fertile female of the same species (or a sufficiently close one), via sexual intercourse with her.\n\n \nTransverse section through the left side of the scrotum and the left testis. The sac of the tunica vaginalis is represented in a distended condition.Between the seminiferous tubules are special cells called interstitial cells (Leydig cells) where testosterone and other androgens are formed.\nin the absence of these testis I doubt whether that person could have any capacity for reproduction

Hormones... just hormones. Female sex hormones tend to lower your basal metabolic rate (BMR). BMR determines the rate at which you burn calories and produce heat. With a low BMR (as with excess female sex hormones) means less calories being burnt and more weight gain as fat. Thyroid hormones also play a vital role. Testosterone which is the male sex hormone, raises BMR. That is why men are bit more physically active than women, because they have more testosterone. Both sexes have both hormones but not in equal amounts. Of course there are aberrants.

Actually sexual appetite is caused by the increased activity of hormone testosterone in males and andosterone in females. Now with the release of either of the hormone, the brain recieves stimuli that guide our thoughts to the sexual activities and thus leading guys to "gals". The effect of the female sex hormone is also there but females have the ability to keep it off their brains..

Estrogens (also oestrogens) are a group of steroid compounds, named for their importance in the oestrus cycle, and functioning as the primary female sex hormone. While estrogens are present in both men and women, they are usually present at significantly higher levels in women of reproductive age. They promote the development of female secondary sex characteristics, such as breasts, and are also involved in the thickening of the endometrium and other aspects of regulating the menstrual cycle.\n\nEstrogen is produced primarily by developing follicles in the ovaries, the corpus luteum and the placenta. Follicle stimulating hormone (FSH) and luteinizing hormone (LH) stimulate the production of estrogen in the ovaries. Some estrogens are also produced in smaller amounts by other tissues such as the liver, adrenal glands and the breasts. These secondary sources of estrogen are especially important in post-menopausal women.\n\nSynthesis of estrogens starts in theca interna cells in the ovary, by the synthesis of androstenedione from cholesterol. Androstenedione is a substance of moderate androgenic activity. This compound crosses the basal membrane into the surrounding granulosa cells, where it is converted to estrone or estradiol, either immediately or through testosterone. The conversion of testosterone to estradiol, and of androstenedione to estrone, is catalyzed by the enzyme aromatase.\n\nEstradiol levels vary through the menstrual cycle, with levels highest just before ovulation.-

pheromones.. sex hormones . it comes from males and females usaly from the sweat glands

Yes, this is called gynecomastia and can occur in men who take female hormones (for whatever reason) and some other medications (such as cimetidine and spironolactone). This can also happen in patients with several disorders: chronic liver disease, hyperthyroidism, testicular tumors, klinefelter's syndrome, and many more.

Testosterone boosts growth in humans. Men have more testosterone which is why they are usually bigger. As men grow their larynx grows and the Adam's apple bulges.\n\nA larger larynx is also why men usually have deeper voices.

Depends on the hormone.  Different glands produce different hormones.  Some are produced by the hypothalamus in the brain, the thyroid, the adrenal glands on the kidneys, the liver, & the testis & ovaries.

Read this first\n\nhttp://en.wikipedia.org/wiki/Anabolic_steroid\n\nIf you still have problem, just add some more details, someone or I may help again.\n\nAnabolic androgenic steroids produce both anabolic and virilization (also known as androgenic) effects. Most anabolic steroids work in two simultaneous ways. First, they work by binding the androgen receptor and increasing protein synthesis. Second, they also reduce recovery time by blocking the effects of the stress hormone, cortisol, on muscle tissue. As a result, catabolism of the body's muscle mass is greatly reduced.\n\nExamples of anabolic effects:\n\n>Increased protein synthesis from amino acids \n>Increased muscle mass and strength\n>Increased appetite \n>Increased bone remodeling and growth \n>Stimulation of bone marrow increasing production of red blood cells \n\nExamples of virilizing/androgenic effects:\n\n>Growth of the clitoris (clitoral hypertrophy) in females and the penis in male children (the adult penis does not grow indefinitely even when exposed to high doses of androgens) \n>Increased growth of androgen-sensitive hair (pubic, beard, chest, and limb hair) \n>Increased vocal cord size, deepening the voice \n>Increased libido \n>Suppression of endogenous sex hormones \n>Impaired spermatogenesis

From Mens Health and Well Being Association\n\nTestosterone is not just a sex hormone.  Every cell in the body has a receptor for testosterone. It is vital in the production of protein and therefore in the formation of muscle. It has a key role in the manufacture of bone. It improves the oxygen uptake of cells, helps control blood sugar, helps regulate cholesterol levels and helps maintain a powerful immune system. It helps concentration, improves mood and may protect against Alzheimer’s disease.\nThe male form of menopause is called andropause and is caused by a slow decline in testosterone production by the testicles and adrenal glands.  In men, 90-95% of testosterone is produced by the Leydig cells of the testicles and the remainder is formed by the adrenals. Unlike the female menopause, which is caused by a sudden decrease in hormone levels, the male andropause occurs much more gradually over a 20 year period and therefore may be less obvious.\n\nPeak testosterone levels in men occur in the late teens. After that there is a gradual decline. Andropause typically begins in men in their early forties or fifties. By the age of 50, 50% of men have low testosterone levels compared to age based guidelines. That figure is a lot higher if levels are compared to optimal levels that occurred during youth. By the age of 60 at least 50% of men will have levels of testosterone low enough to start causing serious health problems. A few men are lucky enough to maintain youthful levels right into old age and the result is usually health and vitality. For the rest of us, symptoms of andropause can include:\n \n\n    * fatigue (often the earliest sign). You just don’t feel like getting up in the morning anymore. It’s called the TAT syndrome (Tired All the Time).\n    * depression, anxiety and irritability. It’s called the USTA syndrome (I ‘usta’ enjoy life).\n    * reduced libido\n    * decreased morning erections\n    * loss of drive, creativity and self-confidence\n    * facial wrinkles\n    * muscle pain and stiffness\n    * increased body fat\n    * decreased muscle mass\n    * increased blood pressure\n    * angina\n\n\nIt is associated with an increase in the incidence of heart attacks, strokes and brain ageing.  There is also a strong association between decreased testosterone levels and type 2 diabetes, elevated cholesterol, osteoporosis and arthritis.\n\nSo how do you know if you would benefit form testosterone replacement? First of all, check to see if you have any of the above symptoms.

Researchers believe that female c*m is produced by the Skene's glands, which are located in a woman's urethra and are made of tissue that's similar in composition to a man's prostate gland. These researchers point to chemical analysis of female ejaculate that reveals the presence of high levels of prostatic acid phosphatase (a chemical secreted by the prostate gland and found in semen). This would seem to indicate that a woman's ejaculation is similar in composition to semen (only without the sperm, of course).
