Three biological reasons why men are unfaithful

It is said that the frequency of extramarital affairs in Taiwan has "progressed" from the "seven-year itch" to the "four-year itch"; while the peak period for extramarital affairs among Americans is five years after marriage. Men seem to be becoming more and more promiscuous. In addition to factors such as sex gradually becoming a matter of staying in hotels, increased social interactions, and high competitive pressure, there may be some biological reasons for men's infidelity. In other words, men themselves can't do anything about being unfaithful. Here are some biological reasons why men are unfaithful.

XY chromosomes make men more aggressive

The natural mission of sex chromosomes is to reproduce. Compared with the XX combination, X and Y in the XY combination are in a competitive environment. Both X and Y hope to "compete for jobs". Reproduction inherently involves competition. The males of the XY combination are more sexually aggressive, or in other words, Y is more sexually aggressive.

Male animals are generally sexually aggressive

The sexual aggressiveness of male animals is manifested in all aspects. The strongest male mammals are generally the "emperors". They "occupy" the females in the group and are willing to fight for the "throne". In fact, they are fighting for the opportunity to pass on genes and maintain their dominant position in effectively passing on their own genes. What's more, they are willing to sacrifice their lives to pass on their genes. There is a kind of spider where the male is small and the female is big, and there is also a praying mantis where the male is eaten by the female immediately after mating. They are willing to sacrifice their bodies to reproduce offspring. Animals do not have consciousness or thoughts; this is just their nature. The continuation of the species requires such nature and also sexual competition.

Finding a way out for sperm memory advantage

It is generally believed that the normal range of a man's sperm count is between 60 million and 120 million per milliliter, with 80 million per milliliter being the middle number. Each ejaculation is 1 to 6 milliliters, with an average of about 4 milliliters, which means there are an average of 300 million sperm each time. Women ovulate once a month on average, and each egg only receives one sperm. With 300 million sperm competing for one position, the intensity of the competition is indescribable, and the fierce internal competition drives the active external search. This biological competitive drive is difficult to imagine with consciousness, but it is a biological existence.

Reasons other than “reasons”

Humans are animals, but they are rational and advanced animals. The biological "reasons" are all characteristics of "animality". The development and progress of human society itself are constantly transforming and diluting its own "animality" and "beastiality"; at the same time, it is constantly improving its own "humanity" level. For example, human beings have gone through the "matriarchal society" of polyandry and the "patriarchal" society of polygamy, and evolved into the current civilized society of monogamy. The constantly improving social norms are restricting the biological "reasons", and the constantly developing rationality is managing the biological "reasons". People will not "act recklessly" like animals. For example, no matter what kind of social and cultural form, incest will be universally and strongly condemned and will definitely be severely punished by law.
