Oxytocin is a peptide hormone and neuropeptide normally produced in the hypothalamus and released by the posterior pituitary. [4] Present in animals since early stages of evolution, in humans it plays roles in behavior that include social bonding, love, reproduction, childbirth, and the period after childbirth.
Oxytocin is released at orgasm and is associated with both sexual pleasure and the formation of emotional bonds. [13] Based on the pleasure model of sexual motivation, the increased sexual pleasure that occurs following oxytocin release may encourage motivation to engage in future sexual activities.
In 1995, rage was hypothesized to occur when oxytocin, vasopressin, and corticotropin-releasing hormone are rapidly released from the hypothalamus. This results in the pituitary gland producing and releasing large amounts of the adrenocorticotropic hormone, which causes the adrenal cortex to release corticosteroids. This chain reaction occurs ...
Most people just think of men when they hear testosterone, but the primary male sex hormone is produced in women too (in the ovaries, in fact) and it turns out that more of it is released ...
The biology of romantic love has been explored by such biological sciences as evolutionary psychology, evolutionary biology, anthropology and neuroscience.Specific chemical substances such as oxytocin and dopamine are studied in the context of their roles in producing human experiences, emotions and behaviors that are associated with romantic love.
Testosterone is the most commonly studied hormone involved with sexuality. It plays a key role in sexual arousal in males, with strong effects on central arousal mechanisms. [ 65 ] The connection between testosterone and sexual arousal is more complex in females.
It has been shown to lead to reductions in stress hormones such as cortisol and epinephrine. When laughing, the brain releases endorphins that can relieve some physical pain. [ 20 ] Laughter also boosts the number of antibody-producing cells and enhances the effectiveness of T-cells, leading to a stronger immune system. [ 21 ]
5-DHT or DHT is a male reproductive hormone that targets the prostate gland, bulbourethral gland, seminal vesicles, penis and scrotum and promotes growth/mitosis/cell maturation and differentiation. Testosterone is converted to 5-DHT by 5alpha-reductase, usually with in the target tissues of 5-DHT because of the need for high concentrations of ...
