What Effects do Male Pheromones Have on Women?
You might never guess from all the hype and hoopla about male pheromones that investigating how they affect women’s hormone levels is a very recent research activity. The effect of pheromones on physiology in animals is quite clear, but only since the late 1990s have scientists attempted to prove that these effects occur in humans, too.
The primary design of most research studies trying to pin down the relationship between male pheromones and female physiology focuses on how women respond to male sweat or perspiration. Pheromones are secreted primarily by the apocrine glands in the human armpits (axillae). By acting on the hypothalamus and the pituitary gland in the brain, pheromones increase the secretion of the gonadotropins, luteinizing hormone (LH) and follicle-stimulating hormone (FSH).
Several studies track a rise in one or both of these hormones after women were exposed to male pheromones. Exposure to male pheromones typically happens through smelling an extract of male sweat or a T-shirt that has become imbued with male sweat after being worn for an extended period.
In women, LH and FSH increase the blood levels of estrogen, progesterone, and androgens. The first two of these are essential […]
