datadragon Posted February 14, 2018 Share Posted February 14, 2018 (edited) Alpha Androstenol in my research seems to be the cause of some change in menstrual cycle and a large contributor to early puberty in girls. There have been many links between father absence and earlier puberty in girls. I was able to find an article that pointed me to the idea that its the presence of a non biological male in the household and not the absence of a father... Without Dad little girls grow up too fast Looking into that further as to what might cause that, alpha androstenol has been found in studies to decrease luteinizing hormone (LH) pulse frequency during the follicular phase of the human menstrual cycle causing a change. Lutenizing Hormone is a pituitary hormone that triggers ovulation in a woman. There is no question on the many studies by different authors on this part. https://academic.oup.com/biolreprod/article/68/6/2107/2683595 https://academic.oup.com/chemse/article/25/4/465/342748 Married vs unmarried women had a difference https://www.ncbi.nlm.nih.gov/pubmed/20977093 A few other of the reported adjustments in cycles included: two days closer together over a four to six-month interval (McClintock, 1971) and a 1.4 day shortening (Stern & McClintock, 1998). Luteinizing Hormone also is highly correlated with sex drive in women, it surges just prior to ovulation time when sex drive is highest. It also causes secretion of testosterone in men from the testicular Leydig cells. So Alpha Androstenol will also have effects in both women and men there from the increase in LH. https://www.ncbi.nlm.nih.gov/pubmed/20646176 I dont see strong evidence yet however that this also means women sync up their cycles simply from the pulse change, only that there is definate effect on luteinizing hormone causing a change from the exposure to alpha androstenol, as well as has been shown to start puberty earlier from the effect on LH in mice, and based on that article probably in those who are non related. The amount of change should also vary further based on exposure timeframe. Edited February 17, 2018 by datadragon Link to comment Share on other sites More sharing options...
