We know of the menstruation cycle in women. But is there a weekly cycle of testosterone production in men?
This shows that during abstinence, testosterone spikes on the 6th and 7th days.
Could this testosterone spike be in most males – such that it’s 7 day cycle, fits into the female 28 day one?
Found this article that seems to bolster that idea.
“Fertile Women Have a Heightened Sense of Smell – reaction to male pheromones is especially high.”
“Naturally cycling women near ovulation were more sensitive to musk and the pheromones than the women on contraceptives.” From Scientific American Mind Sept/Oct 2013
