In recent decades, an increase in the incidence of problems related to fertility and low testosterone levels in young people has been observed.
- Low sperm production;
- Infertility;
- Micro penis;
- Erectile dysfunction;
- Low sexual desire;
- Poor development of male characteristics;
- Cryptorchidism, which is the condition in which the testicles do not descend into the scrotum;
Testosterone decline is a trend in developed and developing countries. According to the study, from 1999 to 2000, there was a 20% decline in testosterone among young men, and a 10% to 40% decline in adults over 39 years old. [11]
The problem appears to only affect white men of European and Asian descent while black men of African descent appear to be unaffected by the problem.

Reduced penis is one of the effects of testosterone loss. |
The cause of the problem:
The main cause of this problem is the increasing exposure to substances that act as hormone disruptors, which contain:
- Antiandrogens, which are substances that block the effect of testosterone;
- Estrogenic, which is the main female hormone.
Food is the main source of exposure to hormone disruptors, due to the use of pesticides and other substances during the production process.
With the growing demand for food, the agricultural industry is forced to seek greater productivity and efficiency, and with this, the use of pesticides has become more frequent, intense and indiscriminate.
Many of these pesticides in use are known to cause hormonal dysregulation, such as dichlorodiphenyldichloroethylene (DDE) and fungicides such as vinclozolin. Despite the side effects, large-scale food production makes the use of pesticides inevitable, and therefore, these pesticides are allowed to be used under certain requirements, such as the minimum time interval between the use of the pesticide and the harvest. , however in practice, these requirements are not met correctly.

Some of the banned pesticides are still commercialized |
Furthermore, pesticides banned due to their high impact on hormonal disruption are still used on a large scale and due to a lack of supervision, whether due to the difficulty of monitoring their use in the field or due to intentional negligence, due to the government's interest in meeting the demand for food for the population.
In addition to pesticides, there are other sources of exposure to hormone disruptors in food, due to direct or indirect consumption (such as ingredients). Among the main sources are:
- Cow's milk: Cow's milk contains considerable concentrations of estrogen, due to the gestation process necessary for milk production, and the use of hormones to extend the time of milk production after pregnancy;
- Soy: soy contains isoflavones, a type of plant estrogen (phytoestrogen) that has a similar function to human estrogen, which despite having a weaker effect, can have a major impact on hormonal dysregulation when exposure is continuous (daily consumption);
There are many other sources of contamination, such as contact with water, soil contaminated by pesticides, industrial products such as plastic packaging, the inner lining of cans, the use of plastic bottles or cups, baby bottle nipples, the use of beauty or personal hygiene products, such as makeup, nail polish, moisturizer, sunscreen, shampoo, sunscreen), air conditioning pipes and others.
The research suggests that the population is exposed to hormone disruptors on a much larger scale than anticipated, as tests that verify safety for human health do not detect all substances that affect hormonal regulation in humans, as they use rodents that are less sensitive to the effects of hormonal regulation than humans.
How hormone disruptors affect masculinity
Hormone disruptors act in two ways: affecting the programming of male characteristics and environmental exposure
Exposure to hormone disruptors causes a reduction in masculine characteristics during exposure, such as reduced fertility, low libido, impotence and loss of masculine behavior. The effects tend to disappear when exposure to hormone disruptors is stopped, but the effects of long-term exposure are still unknown.
Changing the programming of male characteristics:
When exposure occurs during the programming phases of male characteristics, the effect becomes irreversible.
There are two critical periods in which exposure to hormone disruptors permanently affects male characteristics, which are during pregnancy and during the development phase until the end of puberty.
In addition to being permanent, male hormonal dysregulation is hereditary, that is, it is inherited by descendants. This means that a man who has suffered a reduction in masculine characteristics due to the effect of hormone disruptors will pass this effect on to his children, and as exposure to hormone disruptors increases each year, this will cause a continuous cycle of reduced masculinity, generation after generation.
Why Black Men Are Not Affected?
The critical period for exposure to hormone disruptors during pregnancy occurs between weeks 7 and 15, where the most important phase of programming male characteristics occurs. Failure at this stage of development causes an irreversible reduction in male characteristics [02].
A 1988 survey found that during pregnancy, black women have a testosterone production that is approximately 48% higher than women of other races [01][03]. The hypothesis is that this additional amount of testosterone provides protection against the effects of substances that cause hormonal dysregulation, reducing or nullifying the effects.
During the development phase until the end of puberty, where the second critical period for the formation of male characteristics occurs, it was found that young black men have approximately 20% more free testosterone than young white men of the same age [04] . This extra testosterone would also act as protection against hormone disruptors.
In addition to periods of programming male characteristics, black men have higher testosterone levels than other races throughout their lives [09], which would also protect them from the transitory effects of exposure to hormone disruptors.
The higher amount of testosterone during the development phases indicates why black men have more pronounced masculine characteristics such as a lower percentage of fat, greater muscle mass, and larger and more developed sexual organs [09].
Hormone disruptors and changes in society
The populations of Nordic countries, Europe and the USA, have experienced an increase in problems related to male fertility, with an increasing number of young people seeking treatment for sexual impotence [10].
The most relevant impact of hormone disruptors is their hereditary effect, that is, an individual who has suffered underdevelopment of male characteristics due to exposure to hormone disruptors will transmit these characteristics to their descendants [05][06][07][08 ].
This has the potential to permanently alter the aesthetic and reproductive characteristics of a breed over the course of a few decades.
In a near future
With continued and increasing exposure to hormone disruptors, white and Asian men are in an ongoing cycle of loss of masculinity.
In this scenario, in a few generations we will have a population of white men with a partial or total absence of masculine characteristics, while black men are establishing themselves as the standard of masculinity.
It is possible that in a few decades black men will become the only viable option for female reproduction and pleasure.

Amazing! This just proves what I've been feeling for a long time... Congratulations on the post!
ReplyDeleteVery interesting! There is more to be explained and many questions to still answer. In the USA, there is a rise of 'transgenderism' and this includes black males. Such males say they are female, dressing up in girl outfits and so on, and will even participate in female sports often. There are also males, again black males included, who cross dress and are featured as 'transgender' models on magazines and on television commercials. Clearly this shows black men are too acting feminine and are 'sissies' to use that colloquialism. I find that more striking since in the USA black males are about 6% of the total population so the number of black men included in this 'transgender' craze, even teenage black males who compete in girls high school sports, is overrepresented in amount. Males across the board seem to susceptible to the 'transgender' fad with out barriers set by race.
ReplyDeleteI also must point out that gif shows two males having sex. Homosexuality is not traditionally viewed as masculine and virile or strong, so the black man having gay sex is just as detached from the classic hallmarks of masculinity as the white man who is being sodomized. More analysis of these matters will happen in years to come I am sure, given these issues don't seem to be disappearing.
It's an interesting point of view.
ReplyDeleteIf you can, please indicate the sources regarding this membership of black transgender people.
The post highlights the progressive loss of masculinity of white men from a purely biological point of view.
We are making a post about how the loss of masculine behavior as a societal behavioral trend across society, which considers white masculinity as something toxic. But some of this can also affect black men.
However, unlike white masculinity, black masculinity is socially seen as an expression of culture, which is why black men have become the standard of masculinity in commercials and TV shows.
There is no cultural consensus that having sexual relations with a trans feminine woman is homosexuality, since the attraction is caused by the feminine appearance.
Masculinity is a set of characteristics that indicate that the individual is an alpha male, such as dominant behavior, muscles and masculine appearance.
So true <3
