Pheromones are naturally occurring chemical secretions that the fertile body releases externally, which sends messages to potential mates and generates sexual and reproductive responses. Scientists are still uncertain about whether the pheromones have an influence on the sexual life, relationships and physical attraction among humans and those doubts have led to many researches that follow the development of that type of subconscious communication. Biologists have found out that there are four classes of pheromonal communication: repellants, bond relationships between mothers and babies, synchronization of the fertile period in a closed group and the type, which promotes sexual attractiveness and focuses the attention of individuals of the opposite sex. According to a research, made by Dr. Winnifred Cutler, the five factors that determine the sexual attractiveness when it comes to women are: physical appearance and grooming, social skills, sexual motivation and interest in close contact, sexual skills and finally, excretion of sex attractant pheromones. Her study proved that during the time people have been under the effect of a placebo, only 24% would receive more attention, while with those, who have been taking real pheromones, the percentage is around 76%.

As we gained more knowledge on the endocrine system in the 20th century two men, Magnus Hirschfeld and Auguste Florel speculated that hormone imbalances could result in homosexuality. Genetic factors began to be considered in the 1940s. Since then there have been numerous studies attempting to prove the genetic predisposition to homosexuality. The earliest experiment in biological research began in 1938 with the research of Alfred Kinsey. Kinsey was studying human sexuality with the goal of discoverin... ... middle of paper ... ...sexuality–heterosexuality.
