Why male production organ is outside?
920712
The male reproductive organ produces sperms (male gametes).These are short lived,temperature sensitive,acid sensitive.The body temp.(normal)is 37^c.The sperms get destroyed at this temp.They require temp. 2^c less than body temp for survival and normal functioning.Hence, testes are located outside the body.

Men can't possible handle birth because they don't have the proper organs to host eggs and keep them fertile until conception. Men don't have wide enough hips for a uterus, and a vaginal canal where hte baby is born through.

The previous answer is incorrect.  It will produce a male offspring if it fertilizes an egg.  Males have a Y chromosone, females have x chromosones.

because men still have the capabiltiy to produce milk...it may be weird but through the power of suggestion or with hormones it can be done... and has already been done...\n\nmost people might say its vestigial but that wouldnt be so if its still fully functional... anyway hope this helps..\n\nps: perhaps one day in the future the need will arise for men to use them (once again?)

They are hermaphrodite, that means they've got both male and female organs, still they need a partner so that they can exchange sperm, they do it by mating. the sperm stored in the seminal receptacle is later used in the fertilization of eggs and are then released in a cocoon, the new earthworm come out in about 2-3 weeks.

Well it comes from the testicles through the vas defference, usually excreted during ....oh... semmen..... my bad.

umm... masturbation if it's the organ i think u mean... if u have sex quite often, the body gets used to generating alot of sperm... so when he leaves, it still generates it, and when there's no ejaculation, it builds... and causes uncomfortable cramps... try slowing down on the sex about 3-4 weeks ahead of time... and wear loose pants and underwear (in that area)...  other times, it could just be the fact that his "organ" is not ummm... free lets say that... when wearing tight underwear, or sitting to long in an uncomfortable position too long this happens to men....

There is a lot more protections built in to protect the testes than most realize, but they may not be in the design or style YOU think is protective.  The testes are EXTERNALLY located (in scrotum) to protect them from hyperthermia.  Being external is cooler and that is a protective design feature. In fact, oneis lower than the other to prevent them from getting too bumped whilenext to each other, esp between the legs. In fact, both the Dartos and Cremaster muscles help with this too, adjusting the closeness of the testes to the body based on the environmental temp, thus keeping the testicles the critcal proper temp to keep meiosis or sperm production going.  In fact, during the fight or flight mechanism, inc during climax, these muscles adjust the testes, which are pulled up close to the body to help protect them.  Some males will also tell you that the testicles can even go back up into the inguinal canal a bit so that they are protected from harshness of an uncomfortable hard surface like a bicycle seat or motocross ride on a dirt bike (hopefully not for too long, so as to prevent hyperthermia) or even to protect them from hypothermia.  Another protective device is the production of a HUGE number of sperm throughout life and per ejaculate.  A normal male can have 250-300 million sperm per ejaculate.  A huge number of sperm die with each ejaculation, only a few can survive the trip to the egg.  The testes are also covered with a very tough connective tissue called the tunica albagenia, and it helps give them their characteristic "egg" shape. Another protection is the "wet dream" mechanism.  IF a male has not ejaculated recently, an unconscious wet dream can help release some old sperm so that a fresh batch is kept ready and available.  In addiition, if a male has had too long or hot of a jacuzzi or has worn too hot-tight pants-underwear, or has been exposed to something potentially toxic in his environment, etc, this unconscious ejaculation can help get rid of a batch that might be defective or a weaker quality.  As it is, about 20% of a"normal" males sperm are visually defective under the microscope (with 2 heads or 2 or three tails, etc) but there is opportunity for new batches on a regular basis.  Female eggs, on the other hand, have the maximum number at the fetal stage and the number of her eggs is decreasing all her life.  The design of all the human body is a magnificant creation!  Thousands of mechanisms are included to keep the body in homeostasis, inc many to keep the testes and sperm protected from harm.  The chemical nature of semen is such that the sperm are protected too. There are so many protective mechanisms! The fact that they are SO sensitive is also a protective mechanism. Males keep that on their mind a lot and will usually do a lot tokeep the "family jewels" safe from damage.

Good question...\n\nAccording to a previous best answer to the same question:\n\n"To maintain the low temperature, so the temperature is cooler than our body. Sperm will die in heat."\n\nSeems like a reasonable answer to me.\n\n(But I think your theory is pretty darn funny!) :D

Good grief, you need some basic understanding of human anatomy: without a blood supply nothing can live outside the human body. When organs are transplanted they are held suspended on ice in coolers in solutions made to mimic body fluids.  Kidneys cannot live outside the human body and must be connected to a blood supply to function.\n\n A fish breathes water through its gills and cannot live on land unless it is amphibian, in which case it is not a fish. A fish is nothing remotely resembling a human kidney.\n\nhttp://en.wikipedia.org/wiki/Amphibian

in our caveman days it served several purposes. first it helped to protect the genitals from dirt and other elements, in guys it would also help to keep the are warm. sperm need a certain temperature to stay alive, if it gets too cold they die. also the hair would help to hold the smell. gross nowadays but back then the smell was what people were attracted to, there's a lot of pheromones in sweat.

Your body is producing to much testosterone witch is the male hormone that causes hair growth in places like the face.

Men have more male hormones near the genitals that tend to stimulate hair growth thus we have more hair there

All men are born sterile, it is after puberty that they can breed and produce kids.\ngo to bed little boy I think I hear your mommy.

Semen is a fluid that contains spermatozoa. It is secreted by the gonads (sexual glands) of male or hermaphroditic animals, including slugs, for fertilization of female ova. Semen discharged by an animal or human is known as ejaculate, and the process of discharge is called ejaculation. Like blood, semen consists of two parts, the cellular part (spermatozoa and in some instances leucocytes and epithelial cells) and noncellular part (seminal plasma).\n\nDepending on the species, spermatozoa can fertilize ova externally or internally. In external fertilization, the spermatozoa fertilize the ova directly, outside of the female's sexual organs. Female fish, for example, spawn ova into their aquatic environment, where they are fertilized by the semen of the male fish.\n\nDuring internal fertilization, however, fertilization occurs inside the female's sexual organs. Internal fertilization takes places after insemination of a female by a male through copulation. In low vertebrates (amphibians, reptiles, birds and monotreme mammals), copulation is achieved through the physical mating of the cloaca of the male and female. In marsupial and placental mammals, copulation occurs through the vagina.\n\nMammalian semen is a whitish, milky fluid, very viscous, containing water and small amounts of salt, vitamin D, protein, and fructose. The plasma portion of semen may contain dissolved water- and fat-soluble constituents, depending on the diet of the organism in question.\n\nApproximately 200- to 500-million spermatozoa (also called sperm or spermatozoans), produced in the testes, are released per ejaculation. However, they make up only about 2–5% of the volume of semen. The bulk of the semen is composed of seminal plasma, the fluid portion of semen. This fluid is contributed by the accessory male reproductive organs. Some 60% of the volume of ejaculate is produced by the seminal vesicles, and most of the remainder is generated by the prostate. A small amount of viscous mucus secreted by the bulbourethral glands contributes to the cohesive jelly-like texture of semen.\n\nSeminal plasma of humans contains a complex range of organic and inorganic constituents. They include metal and salt ions, sugars, lipids, steroid hormones, enzymes, prostaglandin hormones, amino acids and basic amines. The seminal plasma provides a nutritive and protective medium for the spermatozoa during their journey through the female reproductive tract. The normal environment of the vagina is a hostile one for sperm cells, as it is very acidic (from the native microflora producing lactic acid), viscous, and patrolled by immune cells. The components in the seminal plasma attempt to compensate for this hostile environment.\n\nBasic amines such as putrescine, spermine, spermidine and cadaverine are responsible for the smell and flavor of semen. These alkaline bases counteract the acidic environment of the vaginal canal (which is harmful to sperm), and protect DNA inside the sperm from acidic denaturation. Salts and metal ions in the semen help to create a more hospitable environment for the sperm in the vaginal canal. A typical ejaculation can contain up to 5 mg of zinc. Zinc serves to help to stabilize the DNA-containing chromatin in the sperm cells. A zinc deficiency may result in lowered fertility because of increased sperm fragility. Zinc deficiency can also adversely affect spermatogenesis.\n\nThe simple sugar fructose is the main energy source of sperm cells, which rely entirely on sugars from the seminal plasma for energy. Other components of semen (mucus and texturizing proteins) serve to increase the mobility of sperm cells in the vagina and cervix by creating a less viscous channel for the sperm cells to swim through, and preventing their diffusion out of the semen. Prostaglandin hormones are involved in suppressing an immune response by the female against the foreign semen.
