The proper development of the fetus of the fetus requires not only testosterone of the tests, but also a second hormone produced by other tissues, including the placenta.
According to the Televisa portal, embryo that incorporates a chromosome. His father is something that can occur from the first moment of fertilization.
If you wear it, be a genetic child.
But, as it forms male sexual organs during its development, it must continue to cross a number of weeks.
For this, there is a complex process where any small hormonal variation that passes during pregnancy leads to a wide range of possibilities.
"Virinization starts about 10 weeks of pregnancy and leads to the development and growth of the penis and the development of male internal organs, such as the prostate gland. Prior to this, male and feminine fetuses are genital and similar genitalia . "
Here are the words of Paul A. Fowler, director of the University of Aberdeen Institute of Medical Sciences (Scotland, the United Kingdom), Michelle Bellingham, University of Glasgow, and colleagues in the United Kingdom, France and Sweden
He and a team of researchers from France and the Karolinska Institute of Pediatric Endocrinology in Sweden discovered a further hormonal tract that was involved in the process of producing the penis and the fittings of & # 39 ; r placenta and other organs.
Scientists already know that there is a different source in the synthesis of the hormones that are related to genital development. Here is the mechanism called backdoor.
But, so far, they did not know exactly how it worked.
The PLOS Biology magazine published a study where Fowler and colleagues have made this perception publicly.
For fetal fumes and for the penis to develop properly, testosterone of test and source supertestosterone & # 39; (also known as DHT for its biochemical, 5-dihydrotestosterone composition) that results from the horses and the tests. other organs.
In the placenta, progesterone is involved in the synthesis of androsterone, another hormone capable of producing DHT supertestosterone.
Here is the missing second link that specifies the one that contains the back door of the three steroid hormones.
These hormones act on the genetic tubercle, an organ outline that is common to men and women.
This becomes a male header, rather than a female chlitoris by acting the DHT hormone.
What scientists are still unclear is why these hormonal differences occur.
"We have to find out why there is a difference in androsterone between male and female fetuses," said Paul Fowler.
