The activity change during puberty suggests that humans communicate through odors. [4] Several axillary steroids have been described as possible human pheromones: androstadienol, androstadienone, androstenone, androstenol, and androsterone. Androstenol is the putative female pheromone. [5]
The change in activity during puberty suggest that humans may communicate through odors. [57] Several axillary steroids have been described as possible human pheromones: androstadienol, androstadienone, androstenol, androstenone, and androsterone. Androstenol is the putative female pheromone. [58]

In oriental beetles (Exomala Orientalis), females release the pheromone and passively wait for a male to find them. The males with superior detection and flying abilities are most likely to reach the female beetle first which leads to a selection for genetically-advantageous males. [6] In most species, pheromones are released by the non ...
The following is a list of hormones found in Humans. Spelling is not uniform for many hormones. Spelling is not uniform for many hormones. For example, current North American and international usage uses [ citation needed ] estrogen and gonadotropin, while British usage retains the Greek digraph in oestrogen and favours the earlier spelling ...
The human female reproductive system is a series of organs primarily located inside of the body and around the pelvic region of a female that contribute towards the reproductive process. The human female reproductive system contains three main parts: the vulva , which leads to the vagina, the vaginal opening, to the uterus; the uterus , which ...
An increase in vasopressin has been observed in female rats which have just given birth. Vasopressin is associated with aggressive and hostile behaviours, and is postulated to decrease sexual motivation in females. Vasopressin administered in the female rat brain has been observed to result in an immediate decrease in sexual motivation. [13]
During pregnancy, the syncytiotrophoblast cells of the placenta produce a polypeptide hormone, human placental lactogen (hPL), also known as human chorionic somatomammotropin (hCS). [ 17 ] in six weeks of gestation , production of hPL in maternal plasma is detected, then the concentration of hPL keeps increasing until week 30 of pregnancy. [ 17 ]
