Recently, American scientists discovered unusual substances in sperm that may mean that sperm makes independent decisions and at some point actually thinks for both the man and the woman. This discovery forces us to reconsider the traditional idea of seminal fluid, which was considered only an intermediary - a vehicle that delivers sperm to the egg.
A study led by Rebecca Burch of the State University of New York at Oswego suggests that semen also comes into direct contact with the female body. Birch discovered some unexpected and mysterious substances in sperm, in particular hormones that cause ovulation - that is, the release of a mature female reproductive cell from the ovary into the body cavity. Men may need a similar sperm composition as a strategy to combat hidden ovulation in women.
Although there is always chemical evidence that a woman is ovulating, there are no obvious signs of this process. Therefore, a man who wants to reproduce can waste his time. Thus, sperm, which itself, being in the reproductive organs of a woman, can cause ovulation at the right moment, would be extremely convenient for representatives of the stronger half of humanity.
The concept of safe days, beloved by people who practice unprotected sex, may now be under threat. Birch's findings are a major blow to this concept, which is based on the idea that on some days in a woman's cycle she cannot become pregnant.
However, many scientists still doubt that a significant part of the identified components is able to penetrate the female bloodstream. Despite this, Birch's discovery was an important step in understanding the human reproductive system and could lead to new methods of contraception and infertility treatment.
Thus, sperm, which was previously considered just an intermediary, today comes to the fore as an independent player in the process of conception. This discovery allows for a better understanding of how the human reproductive system works and could lead to new methods of contraception and infertility treatment.
