The sexual response cycle Video
Church Services Are Designed to Influence You. Here’s How the sexual response cycle
There is a correlation between mate choice, odour preference and genetic similarity at the MHC. An evolutionary explanation is that females are attracted to males with MHC alleles different from their own, to provide their offspring with a stronger immune system.

Females currently using hormonal contraceptives preferred the scent of men with MHCs similar to their own. Olfactory cues can be used to recognise kin.
Over thirty olfactory receptor genes have been located at the HLA class I region, [20] which presents responxe from inside the cell to be destroyed by the immune system. HLA- linked olfactory receptor genes can therefore provide a possible mechanism for https://digitales.com.au/blog/wp-content/custom/african-slaves-during-the-nineteenth-century/family-system-dynamics.php HLA- specific odours. Men and women are attracted to the pheromones they produce and HLA is related to the perceptions of other peoples' odours.

Androstenol is produced by fresh male sweat and is most attractive to women, while androstenone is produced once the sweat is exposed to oxygen and is highly unpleasant to women. Studies have shown that women who are at the most fertile stage of their menstrual cycle prefer the smell of men that have higher testosterone levels.
Females, especially when not using hormonal contraceptives, are more attracted to the scent of males heterozygous for HLA. Androstenone, from stale male sweat, is unattractive. However, the same attraction and mate preferences are not held by males for heterozygous females.
Males are, however, more attracted to the scent of females with rare Responsf alleles. For example; pumpkin pie, liquorice, doughnuts, and lavender can increase penile blood flow consequently causing arousal. Studies [26] showed that MP2 has the strongest response produced by female vomeronasal organ VNOwhich is the first stage of the olfactory system.]
