The female hormonal cycle is a function of a highly evolved chemical feedback loop between the pituitary gland and the ovaries and uterus. If conception does not occur after ovulation, 14 days later, the uterus ‘sheds’ its lining in the form of a period, and a new cycle starts all over again. This cycle lasts on average 28 to 30 days. Females are responsible for continuing the human species. Females have very high concentrations of ESTROGEN AND PROGESTERONE. Females have TESTOSTERONE too, but the average amount is 10 x less than that found in men.
The hormone fluctuations in women are vertiginous. Plotted on a graph they resemble a roller coaster. For men, we all know this is NOT the case. We all know that MEN DON’T HAVE PERIODS, but keep in mind that hormones are messengers and work on feedback loops that are dynamic. In men, hormones, specifically that of testosterone, need to follow a rhythm for proper feedback to occur. Patterns emerge, manifesting these changes in relative blood concentrations that have been regularly measured. Given that men do not have a uterus, the signs of any kind of cycle are very subtle. Men are not usually taught to understand these signs and therefore go unnoticed.
