Hormone testing proves that:
In real life, men are accused of being "flirtatious," as if they are naturally lecherous, and male animals in nature also seem to have this problem. However, a new study has found that not all males are so prone to sexual abuse, and at least fathered male marmosets (a small monkey from Central and South America) are very restrained in their sexual needs.
The study was published in the latest issue of the journal Hormones and Behavior.
A young man was sitting in a bar with a young and beautiful girl flirting with him. If he got married, he knew he should pay attention to his behavior, but even if his conscience said not to be distracted and not to do anything out of line, sometimes the temptation of lust outweighed the power of morality, and ultimately he might take that step. But if he were not only married but also a father, would he still be so inclined to take a dangerous step towards sexual disorder? If he were a father, he would turn around and leave and return home, at least when the male marmoset has its own children, it would refuse the temptation of a beautiful opposite sex. Is it possible for humans to do the same?
The social structure of marmosets is very similar to that of humans, and researchers hope to reveal human sexual life through their research.
Researchers at the National Primate Research Center at the University of Wisconsin in Madison discovered this phenomenon through research, and they themselves were surprised by the results. For marmosets, there is a significant difference in sexual orientation between parents and mates without children. This small monkey, whose head is as big as a squirrel, has the same social structure as ours, and its social structure is closer to humans than other primates, so scientists very much like to treat them as research objects.
Endocrinologist Tony Ziegler, a veteran scientist at the National Primate Research Center at the University of Wisconsin, is dedicated to the study of the impact of the social environment on hormones and behavior. She said that studying human sexual life is not easy because it is difficult to maintain all the necessary controls, so she turned to studying marmosets. Together with Charles Snowden, the director of the psychology department at the center, she formed a research team, hoping that male marmosets can bring some light to this important topic.
Male marmosets immediately produce sex related hormones when faced with attractive mates, with an exception of one-third.
They want to know what changes occur in hormone secretion when a male marmoset or even a man faces an attractive opposite sex. When given some stimulation, such as a very pleasant female odor, does the male body begin to immediately produce sex related hormones? Hormones such as testosterone. Obviously, the answer is yes, because marmosets are highly susceptible to affection. Ziegler said, "We have just started conducting experiments and some male guys have not shown normal physiological responses."
Ziegler and his team studied 30 marmosets, and two-thirds of them saw a beautiful opposite sex and their testosterone levels soared within a few minutes. Obviously, they were full of desire for the opposite sex, but another third of marmosets showed no signs of interest, such as their testosterone levels, which barely rose.
"This discovery is very exciting," Ziegler said, because nothing excites a good scientist more than unexpected results. Even with appropriate stimulation, these marmosets still seem uninterested in sex. What's the matter with them? Scientists have found that male marmosets who resist illegal temptations are actually fathers, and male psychology can suppress the production of hormones.
After a little research, Ziegler and Snowden discovered the problem. All those marmosets that resist illegal temptations have become fathers, some have just become fathers, and some have become fathers early on. However, they have little or no response to attractive opposites.
Snowden said that the reason for this situation is that marmosets have a unique social structure. They are different from other primates. Marmosets are monogamous animals, and "loyal couples" give birth to two babies a year or two at a birth. Every member of the family is very united and helps each other, including raising children. As a father, marmosets also do a lot of work for raising children.
Ziegler said that due to such a social structure, a marmoset who acts as a father to any other member of the opposite sex, except its own wife, does not have a strong physiological response. In this case, the male's psychology suppresses the production of hormones, which can cause it to generate great sadness.
Many mammals, such as pigs and cows, respond to sexual stimulation as expected. Will human males do the same?
For an elderly father, this is not a quality issue, but a hormone "switch" that is turned off. Does this make marmosets unique? Other studies have shown that many mammals, such as pigs and cows, respond to sexual stimuli as expected. Within 30 minutes, their system will start up and receive all the hormones needed for sex. When men face sexual temptation, they also react in the same way.
But until now, there was no reason to believe that just being a father would have an impact on the psychological arousal of sexual desire, but at least for marmosets, this is the case. They are indeed different from other animals. Can human males do the same? This requires more research. However, since the social structure of humans is similar to that of marmosets, it would not be surprising if fathers were different from others.
Snowden said this is good news. He said, "I hate all men being accused of being sexually promiscuous and irresponsible. I am very happy that we have finally discovered a species where both females and males who become parents are very responsible."
Latest Findings
The first experiment to confirm that sexual behavior is beneficial for evolution
From an evolutionary perspective, sexual reproduction seems to have more disadvantages than asexual reproduction. Sexual reproduction wastes time and energy, completely confusing beneficial genes, and females (who engage in almost all reproductive work) only transmit half of the female genetic material. Therefore, scientists have always wondered why species bother so much about sexual activity when there are so many drawbacks to sexual reproduction?
Now, using an asexual yeast strain obtained by genetic engineering methods that only includes the basic content of sexual reproduction can eliminate external factors. Recently, scientists have used this method to study and found that sexual activity is indeed beneficial to health, at least for yeast. Yeasts contain small organisms that can reproduce both sexually and asexually. British scientist Matthew Goddard and scientists from Imperial College London have studied two different forms of the same yeast, one that can reproduce both sexually and asexually; The other can only reproduce asexually. They found that under normal circumstances, the "encounters" of the two forms of yeast are the same. However, in extreme cases, sexually active yeasts perform better. "Our findings suggest that sexual reproduction can provide a selective advantage in adapting to new environments," they wrote in a paper published last week in the journal Nature
