TL;DR: The current knowledge on the behavioral, physiological, and molecular aspects of pheromone detection in mammals is discussed in this review.
Abstract: In recent years, considerable progress has been achieved in the comprehension of the profound effects of pheromones on reproductive physiology and behavior Pheromones have been classified as molecules released by individuals and responsible for the elicitation of specific behavioral expressions in members of the same species These signaling molecules, often chemically unrelated, are contained in body fluids like urine, sweat, specialized exocrine glands, and mucous secretions of genitals The standard view of pheromone sensing was based on the assumption that most mammals have two separated olfactory systems with different functional roles: the main olfactory system for recognizing conventional odorant molecules and the vomeronasal system specifically dedicated to the detection of pheromones However, recent studies have reexamined this traditional interpretation showing that both the main olfactory and the vomeronasal systems are actively involved in pheromonal communication The current knowledge on the behavioral, physiological, and molecular aspects of pheromone detection in mammals is discussed in this review

TL;DR: The major endocrine processes during the follicular and luteal phases that precede and follow ovulation are described and the role of nutrition and metabolic status on these processes are briefly discussed.

TL;DR: Only androstenone, exhibiting an intense urine-like odour, has been proved to contribute significantly to boar taint, but this compound does not explain all of the off-odours associated with boar fat.

TL;DR: In sheep, preventing the vomeronasal organ (VNO) from functioning does not affect the female responses to male odor suggesting that, unlike in rodents, the accessory olfactory system does not play the major role in the perception of this pheromonal cue.

TL;DR: The studies suggest that probing the vaginal cervix rats exerts an analgesic action, apparently not due to an action on the final motor pathway, for limb or facial movement induced by electrical stimulation of the pyramidal tract was not suppressed by the probing.
