About the ejaculation mechanism

Ejaculation typically occur at the peak of the pleasurable feelings in a man that is excited enough and typically it occurs during orgasm, that is the stage where these feelings culminate. Before the ejaculation, the seminal vecicles are typically full of seminal fluid having been produced in the prostate.

Both the orgasm and ejaculation occur as a result of sensorial stimuli from the genital region to the spinal cord and brain, and signals sent back via the sympathetic nervous system to the genital organs in responce to these stimuli. The sigals sent back results in steadily stronger erection, inflation and galndular action. These physical responces result in even stronger sensorial stimuli sent to the central bervous system and even stronger signals sent back in responce. Both the feelings and the physical reactions thus increase through several stages until the muscles in the genital area get enoug stimuly to contract and effect an ejaculation.

The mechanism of ejaculation involves 2 reflexes: the "glans-vasal", which brings the semen from the seminal vescicals to the posterior urethra (emission phase of ejaculation), and the "urethromuscular" which ejects it to the exterior (ejection phase).

In the first reflex, the smooth muscles in the seminal vecicals and muscles around them contract to expel the semen into the urethra in response to signals from nerve fibres belonging to the sympathetic nervous system. Upon these signals, the vas deferens, the tube from each testicle also contract so that fluid with sperm cells are blended into the substance from the seminal vescicles before entering the urethra. The tube from the seminal vecicles join with the vas deferens on each side to a common tube and this opens then into the urethra. All these tube connections occur inside the prostate gland.

Also secretions from the bulbourethral glands laying at both sides under the prostata is injected into the urethra.

In the second reflex muscles around the base of the penis and especially around the lower side of the structures of perineum, the bulbuspongious muscles, squeeze rhythmically, pushing the semen through the urethra and out of the penis. Also inner muscles in the pelvic floor, for example the pubococygeus muscles participate in these contractions.

In a man with full seminal vecicles, the ejaculation typically contain 10-15 contractions.

A man experiences usually the first ejculation in the beginning of puberty in the age 12 - 15, and usually during masturbation or during wet sexual dreams. A boy often have had orgasms during masturbations from a much earlier age, but then without any ejaculation.

About deer velvet antler, including waipiti elk velvet antler

Antlers are the usually large and complex horn-like and often branched outsprings on the head of most deer species, especially male individuals. Each antler grows from an attachment point on the skull called a pedicle. While an antler is growing the inside constists of cartilage and it is covered with skin called velvet having a rich blood supply which supplies oxygen and nutrients to the growing structure. When the antler is in the last growing stages, the inside is calcified to real bone. Then the velvet is lost and the antler's bone dies. This dead bone structure is the mature antler.

The elk drops its antler each year, and in the spring of the next year a new antler grows out to its full size. This can only happen if the antler in its growth face contains a lot of vitamins, minerals, essential nutrients and hormons used as tools and building material for this rapid growth.

The antlers are used by the males in fighting games for the opportunity to copulate with the prefered females, and probably also to attract the females. Antlers are shed after each mating season.

Velvet antler is the antler with the velvet still in place.

Velvet antler in the stage before the cartilage in the inside has been calcified to real bone is a mainstay of traditional Chinese medicine, probably second only to ginseng in importance. Typically the antler is cut off near the base after it is about two-thirds of its potential full size, and before any significant calcification occurs.

The antler is dried and is used powdered or in tea form for a wide variety of health remedy and health maintenance purposes.

Substances in the antlers have a generally tonic or strengtening effects on body functions like nerve functions, muscle efficiency, glandular functions, blood generation, respiration, digestion and immune defenses. It also strengthens development, growth and regeneration of body tissues. It also exert anti-inflammatory effects. The more specific functions mostly derive from these gereral effects.

One specific effect directly attributable to these general effects and perhaps also to specific effects on the genitals is a strenghening effect upon libido and sexual performance. Antler will for example stimulate the production of testosterone.

Velvet antler has been hused as a medical remedy by all cultures in the parts of world where animals of the deer familiy is found, including North American Indians, in Tibet, in Korea and in Chine. In the East Acian culture velvet antler is a standardized remedy of the traditional medicine. In Russia velvet antler is systematically used as a general strengthening remedy for athletes. In Korea antler is used by most families as a general health strenghtener and the monthly use of an Korean family is around 30 grams.

Western scientific studies have supported some of the claims, particularly the anti-inflammatory effects and athletic performance enhancement. One Canadian study on young males (football players and police recruits) found higher testosterone levels after taking velvet antler supplements for several weeks.

Since velvet antler is a structure with high tissue growth activity, it wil naturally contain high concentration of tissue hormons stimulating growth and maturation, and a high concentration of vitamins and minerals. Since calcium and other minerals are being rapidly deposited into the growing antler, but much of them have not yet been incorporated in a rigid crystallic structure, velvet antler probably contains these minerals in a form that it is easy to take up from the digestive tract.

Moose, as all members of the deer family, will produce new antlers yearly (primarily males, except in caribou/reindeer). The bulls are not harmed by antler removal, which is generally done around June in the northern hemisphere. After the antlers are cut off the bull may grow a small antler pair to replace them or perhaps no regrowth, but the antler base is left, and that "button" will be shed early the following year, at the same time the whole antler would have been shed, when the new antlers start to grow.

Exceptionally large elk antlers can weigh 50 lb (20 kg) for a pair. These grow rapidly from about March or April till July (again, Northern hemisphere). The velvet of the antlers are said to be the fastest growing membrane known, and it is this rapidly growing tissue that contains the micronutrients needed to improve some human health deficiencies.

Most of the world's supply of velvet antler comes from red deer and elk or wapiti, including a large deer farming industry in New Zealand. A smaller percent is produced in America, mostly from elk. Due to the size and quality of Canadian and American elk antlers, they have been a preferred source of velvet. It is most often available in capsule form, containing 250 mg or 500 mg of dried velvet antler powder. The velvet antler is processed under USDA supervision, with routine bacteria testing. It is bottled for commercial use and is available in some health food stores.
