I disagree with this — TimeLine
You are free to--science is not absolute and can always be proven wrong--but we have strong evidence that more testosterone does indeed cause more aggression or tendency towards violence.

"Atavistic residues of aggressive behavior prevailing in animal life determined by testosterone remain in man, attenuated and suppressed by familial and social inhibitions, but still manifesting in various intensities and forms from thoughts, anger, verbal aggressiveness, competition, dominance to physical violence. Testosterone plays a significant role in the arousal of these behavioral manifestations in the brain centers involved in aggression and on the development of the muscular system that effects their realization."
"The action of testosterone on the brain begins in embryonic life. During the fourth to fifth month of pregnancy a surge of fetal testosterone occurs reaching adult testosterone levels which induces anatomical and organizational changes in the male embryos brain. Even earlier at the DNA level, the number of CAG repeats in the genes of the androgen receptors appear to play a role in the expression of aggressive behavior. Men with fewer CAG repeats have more active androgen receptors and enhanced testosterone action."
We often assume that since men are biologically stronger that it somehow equates to biologically likely to be aggressive but again, aggression is not physical. It is a subjective disposition and if men act on this, they do so for mostly social and environmental reasons and not because they are genetically predisposed — TimeLine
This, too, goes against our current understanding of human biology, as explained in the quotation I just cited.
The word 'irrational' is a strong word to use for fluctuations in hormones that - depending on the woman - has a minor or temporary affect, just as much as a bad night sleep can have. Can you show me this scientific evidence that women become 'irrational' because of their menstrual cycle? — TimeLine
While I think comparing the hormonal changes that happen during this stage of the menstrual cycle with a bad night's sleep is disingenuous, you're probably right that my word choice wasn't quite fitting. Irrationality isn't technically a very scientific term.
However, as I have already said, my only point in bringing this up was as an example of biological differences between males and females. I did not say or imply that men are more rational than women. I wasn't meaning to comment on women's rationality at all, only at one of the many biological differences between men and women.
For what it's worth, though, I've had long-term romantic relationships with 4 women in my life who I have lived with for varying amounts of time, and every one of them displayed what I would characterize--and what
they also referred to--as irrational behavior.
I also grew up with a mother and three sisters, and every one of them have many times addressed the fact that when they have PMS, they are irrational. Their words.
This is not scientific evidence, this is anecdotal. But seeing as how eight out of eight or 100% of the women I have been closest to in my life have both clearly displayed what I would characterize as irrational behavior, and verbally confirmed on multiple occasions that they, too, view themselves as being irrational during this time, I feel confident concluding that it is a common occurrence among females during this stage of their menstrual cycle. I will not try to argue that there is scientific evidence for irrationality, since I personally don't believe that is possible due to irrationality being a fairly subjective term. I also won't try to argue that my experience with these 8 women applies to all women. But I find it perfectly reasonable for someone with my experiences to conclude that the biological/hormonal changes that happen during the pre-menstrual stage often cause women to be more irrational during this time.
