Difference between Hormones and Pheromones

Hormones are released inside the bodies of both plants and animals. Endocrine glands are the organs that create and release hormones whereas Pheromones are substances that animals and insects create that alter the behaviour of other members of the same species.

Here are some of the main differences between hormones and pheromones to help you understand how both differ:

Hormones Vs Pheromones:


Hormones act as chemical messengers.

Endocrine glands are those that make and emit hormones. For the purpose of getting to their intended tissues, hormones are discharged right into the circulation.

Hormones fall into three categories: steroids, proteins/peptides, and derivatives of amino acids.

Progesterone, estragon, and testosterone are examples of steroid hormones that are used in both male and female sex hormones.

Cortisone, a steroid hormone, is also used by insects to induce melting.

Peptide hormones including pituitary hormones, insulin, and secretin make up the majority of hormones.

 Adrenaline and thyroxine are two examples of hormones that are derived from amino acids as compared to pheromones.


Pheromones are chemicals produced by animals and insects that influence the behaviour of other members of the same species.

Pheromones are secreted to the outside even though they are created inside the body.

Most pheromones cause the opposite sex to engage in sexual behaviour, all insects often interact with one another using pheromones.

There are numerous varieties of pheromones; to choose a mate and protect oneself from predators, animals employ aggregation pheromones.

These pheromones unite the people in a group, the teams are referred to as aggregations.

What is Difference between Hormones and Pheromones?

Hormones often have an internal influence and only affect the person secreting them while Pheromones are ectohormones, in contrast to the majority of other hormones.

They influence another person’s behaviour since they are secreted outside the body.

Let’s discuss the difference between them as follows:

The regulating compounds that are delivered in blood or sap and stimulate particular cells to carry out their duties are referred to as hormones.Pheromones are chemical substances sent into the environment by animals and insects to affect the behaviour of other members of a species.
Hormones have an effect on the animal or plant that secretes them.They have an effect outside the animal or insect that secretes them as compared to hormones.
There are many different roles that hormones play in the body.Few bodily processes are impacted by pheromones.
Together with the neurological system, hormones coordinate how the body works.Males are drawn to females by pheromones, which serve as messengers and promote sexual reproduction.
Abscisic acid, auxins, cytokinins, pituitary hormones, and male and female sex hormones are types of hormones.Pheromones include, for instance, aggregation pheromones, trail pheromones, signal pheromones, releaser pheromones, and alarm pheromones.


After reading this article you learned a lot about the differences between hormones and pheromones.

The body’s processes can be induced or prevented by hormones both animals and plants can create hormones.

Animals, as well as insects produce pheromones.
