What are Pheromones? When do people emit Pheromones?

Answer 1

Pheromone

A substance that acts as a molecular messenger, transmitting information from one member of a species to another member of the same species. A distinction is made between releaser pheromones, which elicit a rapid, behavioral response, and primer pheromones, which elicit a slower, developmental response and may pave the way for a future behavior.

Communication via pheromones is common throughout nature, including some eukaryotic microorganisms such as fungi that exchange vital chemical signals. The cellular slime molds form large aggregations of amebas which unite to form a sorocarp made up of a long, slender stalk that supports a spore-containing fruiting body. A pheromone is responsible for the aggregation. In several species of algae, relatively simple hydrocarbons act as sperm attractants.

By far the largest number of characterized pheromones come from insect species. In social insects, such as termites and ants, there may be as many as a dozen different types of messages that are used to coordinate the complex activities which must be carried out to maintain a healthy colony. These activities might require specialized pheromones such as trail pheromones (to lead to a food source), alarm pheromones (recruiting soldiers to the site of an enemy attack), or pheromones connected with reproductive behavior. Much less is known about mammalian pheromones because mammalian behavior is more difficult to study. There are, however, a small number of well-characterized mammalian pheromones from pigs, dogs, hamsters, mice, and marmosets.

There is great potential for controlling the behavior of a given species by manipulating its natural chemical signals. For example, pheromones have been used to disrupt the reproduction of certain insect pests. This approach can lead to reduced use of pesticides as well as advances in the control of both agricultural pests and disease vectors.

Answer 2

Defination
Pheromones are naturally occurring substances the fertile body excretes externally, conveying an airborne message to trigger a response from the opposite sex of the same species.

we know pheromones are used by almost all insects and other animals but its unclear how sensitive we are to pheromones.

Territorial pheromones
Laid down in the environment, these pheromones mark the boundaries of an organism's territory. In dogs, these hormones are present in the urine, which they deposit on landmarks serving to mark the perimeter of the claimed territory.

others include: Trail pheromones, Alarm pheromones, Epideictic pheromones...

Most interesting ones are sex pheromones: In animals, sex pheromones indicate the availability of the female for breeding. Many insect species release sex pheromones to attract a mate and many lepidopterans can detect a potential mate from as far away as 10 km. Pheromones can be used in gametes to trail the opposite sex's gametes for fertilization. Pheromones are also used in the detection of estrus in sows. Boar pheromones are sprayed into the sty, and those sows which exhibit sexual arousal are known to be currently available for breeding.

Some companies sell it, here is a comment from their website:
Charlie (Scotland): "I’m the ultimate cynic, degree and MBA educated and always suspicious of product claims. But during the six month period I’ve used this product, my hit rate with women went from about 2 a year, to 7 in six months."

to good to be true!?

Answer 3

I did my senior research on this subject. It is debated whether or not humans emit pheromones (chemical signals detected by the vomeronasal organ (VNO) of animals) Through evolution, we have lost our VNO due to other means of communication. However, some research states that women living in dorms will start to cycle together after living together for a while. Pheromones may still be present afterall but more research needs to be done.

Answer 4

Hi. A chemical emitted by the creature used to influence other creatures of the same species - as opposed to the skunk - and is usually used to attract a mate.

Answer 5

It is a hormone that attracts you to the opposite,or same sex. and is secreted all the time at the start of puberty.

Answer 6

pheremones are emissions of odor/scent caused by living cells.. yes we do emit pheremones -- mostly our body odors

Answer 7

A type of hormone that is excreated during sex.

Answer 8

sex hormones. Do you emit pheremones?
