While women have their own unique and personal issues to contend with, men have a very personal and intimate issue of their own. Men like to feel as masculine as possible when they consider their penile length. However, there are many men that either feel that they don’t have adequate penis length, or they genuinely don’t have enough penis length. The average size of a flacid penis is around three inches, while an erect penis is around five to six inches.

However, there are men who are naturally lacking in penile length. For example there are men who find that they measure at an inch and a half, possible up to two inches when their penis is flaccid. These same men might only achieve an erect length of two to three inches. While experiencing a lack of length is rarely a medical problem, men who experience a lack of penile length suffer emotional and psychological distress. Therefore, these men will seek out devices that will help them to naturally achieve penile length.

Doctors have found that penis extenders do offer come results when men wear these as prescribed. The way that the penis extender works is that it’s attached to the shaft of the penis. The device is weighted, so that it slowly but surely stretches out the shaft of the penis. The skin and the soft tissue of the shaft will eventually stretch, offering the man who wears these devices length. These traction devices are to be worn for up to six hours a day. These should also be worn for six months, in order to notice results.

Men who experienced testing with a penis extender found that when they wore the device for six months, up to six hours a day, they experienced almost an inch of new growth when the penis was in a flaccid state. This includes several manufacturers: X4 labs, Size Genetics, and Jes Extender. When men experienced an erection, they noticed an inch and a half of new growth. For many men, even an extra inch of new growth is something to be very appreciative of. Men feel that every inch counts, because extra length can equate to extra pleasure for their partners.

While a penis extender can work for men who are lacking what is considered to be normal length, there are men who are of normal length, yet would like to add to their sexual abilities. It’s best for men who use a traction penis device to follow instructions and to not wear this device to the extreme. For example, some men wear these devices for more than six hours, or they fall asleep while wearing the device. Doctors have found that when men use these devices to the extreme, men cause permanent damage to their shaft. Men can experience either broken capillaries, or broken areas of their shaft.

However, if a man is willing to be patient and if he is willing to wear a penis extender as prescribed, then they will notice in time that their efforts might be worth the wait.

The term “pheromone” was defined by the German biochemist Peter Karlson and Swiss entomologist Martin Lüscher in 1959. The word has two Greek roots: “pherein” (transport) and “hormone” (excite). Thus, pheromones were defined as substances secreted by individuals that received by other individuals of the same species, cause a specific reaction, behavior or biological change.

The first sex pheromones were discovered in 1959 by Adolf Butenandt (who won the Nobel Prize for Chemistry in 1930), after 20 years of work. From 500 000 females of silkworm (Bombyx mori), he received 6.4 mg of purified attractive sex pheromone: the bombykol (which is actually an alcohol). Adolf Butenandt was not the only one to question the role of these odors. For over 50 years, biologists have been interested in the role of odor emissions in animals and discovered that most living organisms produce substances they release into the environment. Wilson’s article in 1963 entitled “Pheromone “was a trigger for many biologists. Many scientists noticed that the topics they were studying could be reread in light of these new concepts. In 1960, Jeanine Barbier and Michel Pain isolated and identified the queen substance of bees, which inhibits the development of the ovaries of the workers. This was the first pheromone amending known to date.

Since then, progress in the field has been enormous. Numerous pheromones are now known in insects even though the early work of isolation and purification was slow at times. Few pheromones identified in aquatic organisms, however, were reported in brown algae in mold lakes and rivers. Some pheromones were discovered in fungi, one of them producing a sex pheromone: the female gamete secretes a substance that attracts the male gametes. This was the first isolated pheromone from a plant.

In vertebrates, the term pheromone is more elusive and there are many examples. Pheromones have also been identified in rodents, carnivores and monkeys. In these mammals, pheromones are generally secreted by glands near the sexual organs or the head.

Different types of pheromones

There are many kinds of pheromones and they can be divided into two major categories: incentive pheromones that affect the behavior of animals and modifying pheromones that act on the biology of animals.

Pheromones of territory are hormones that animals (e.g. canids) use to mark their territory. Trace pheromones have been identified as bile acid derivatives. The animals use them to trace their tracks (e.g. ants). The alarm pheromones are volatile (or very soluble in water for fish) and they are released by an animal in case of injury or attack by a predator, and that triggers the leak or aggression in other individuals of the same species. Sex pheromones indicate the availability of females to be fertilized. Depending on the type of reproductive cycle of the insect, pheromones play different roles. However, the coupling always takes place at a well-defined life cycle of the insect, and even at a specific time of day sometimes. Sex pheromones are by definition created to ease communication with each other in order to ensure the sustainability of the species.
