What role does chemical attraction play in human relationships?

Chemical attraction, such as pheromones and neurotransmitters, can influence initial attraction and bonding in human relationships. These chemical signals can impact emotions, behavior, and physical attraction between individuals. However, while chemical attraction may play a role in sparking initial interest, it is not the sole determinant of the success or longevity of a relationship. Other factors such as communication, compatibility, and shared values also play significant roles in human relationships.
