Sexual attraction existed in different cultures is controversial. Pheromones have been determined to play a role in sexual attraction between people. They influence gonadal hormone secretion, for example, follicle maturation in the ovaries in females and testosterone and sperm production in males. Research conducted by Donald G. Dutton and Arthur P. Aron in the 1970s aimed to find the relation between sexual attraction and high anxiety conditions. In doing so, 85 male participants were contacted by an attractive female interviewer at either a fear-arousing suspension bridge or a normal bridge. Conclusively, it was shown that the male participants who were asked to
Hormone differently to the same hormonal signal. The rate of hormone biosynthesis and secretion is often regulated by a homeostatic negative feedback control mechanism. Such a mechanism depends on factors that influence the metabolism and excretion of hormones. Thus, higher hormone concentration alone cannot trigger the negative feedback mechanism. Negative feedback must be triggered by overproduction of an "effect" of the hormone. Hormone secretion can be stimulated and inhibited by: One special group of hormones is the tropic hormones that stimulate the hormone production of other endocrine glands. For example, thyroid-stimulating hormone (TSH) causes growth and increased activity of another endocrine
