Immunization against 5α-androstenone in boars

Livestock Production Science, 1985
The effects of specific immunization against 5α-androstenone have been examined in large, genetically homologous groups of boars reared either to bacon weight (90–95 kg live weight) or to heavy manufacturing weight (115–120 kg live weight). At the lighter weight, immunization significantly (P < 0.05) reduced the concentration of androstenone in the ...

Quantitative determination of androstenone in pig adipose tissue

Journal of Chromatography A, 1986
A simple, cheap and rapid method for the quantitative determination of the boar taint substance, 5 alpha-androst-16-en-3-one, in pig adipose tissue is described. After saponification of the fat the androstenone is extracted, derivatised with o-(pentafluorobenzyl)hydroxylamine hydrochloride in pyridine and analysed by fused-silica open-tubular capillary

Androstenone and testosterone levels and testicular morphology of Duroc boars related to estimated breeding value for androstenone

Theriogenology, 2013
Androstenone and testosterone levels in Duroc boars with an estimated breeding value for androstenone (EBV(androstenone)) were followed in the period from birth to sexual maturity. The breeding value for androstenone had been estimated based on androstenone levels in 1202 Duroc boars at an age of 24 weeks. Testosterone and androstenone levels in plasma

128 The Effect of natural product treatments on the hepatic metabolism of androstenone in boars.

Journal of Animal Science
The pregnane X receptor (PXR), constitutive androstane receptor (CAR), and farnesoid X receptor (FXR) are ligand-activated nuclear receptors that modulate the hepatic metabolism of endogenous compounds, including androstenone, a testicular steroid ...

Male Sexual Orientation Affects Sensitivity to Androstenone

Chemosensory Perception, 2009
Androstenone has often been discussed as a human social chemosignal, as it is one of the major contributing substances to the human body odor for which humans possess specific receptors. Here, we investigated whether male sexual orientation influences the perception of androstenone.

The expression of androstenone receptor (OR7D4) in vomeronasal organ and olfactory epithelium of horses.

Domestic Animal Endocrinology, 2020
Androstenone is the first mammalian steroidal pheromone to be identified. Pheromones are chemicals that animals use to communicate within a species. Pheromone detections are related to vomeronasal organ (VNO) and olfactory epithelium (OE) in mammals ...

20  The effects of androstenone on the plasma concentration of serotonin, β-endorphin, and cortisol in horses

, 2021
The neuroendocrine system is the main factor that regulates animal behavior and is generally mediated by internal or external stimuli, including pheromones.

Enhanced Sensitivity to Androstenone Following Regular Exposure to Pemenone

Chemical Senses, 1995
The responses elicited by olfactory stimuli may be modified throughout an organism's life. For example, Wysocki et al. found that regular presentations of 5a-androst-16-en-3-one (androstenone) to anosmic subjects resulted in a graded increase in the perceived intensity of this substance in about half of their subjects (Wysocki et al., 1989).

Norwegian consumers' acceptability of boar tainted meat with different levels of androstenone or skatole as related to their androstenone sensitivity

Meat Science, 2010
The aim of work was to study Norwegian consumers' acceptance of pork meat with different levels of skatole and androstenone. One group of androstenone sensitive consumers (N=46) and one group of non sensitive consumers (N=55) participated in a home test and evaluated 11 samples with different skatole (range 0-0.35 ppm) and androstenone (range 0-9.0 ppm)

Exposure to male sexual scents (androstenone) influences women’s drinking.

Experimental and Clinical Psychopharmacology, 2017
In a demonstration of a heretofore unknown motivational pathway for alcohol consumption, we recently showed that exposure to scents emitted by human females during the fertile phase of their menstrual cycle could increase men's drinking. The current study examined the reverse: whether exposure to male sexual scents (androstenone) would increase women's
