The eggs are able to choose the sperm they attract. This is, at least, what emerges from a study carried out by the universities of Stockholm and Manchester. A work published by the scientific journal The Royal Society, in its section dedicated to ongoing research. This magazine is very relevant. And it is one of the most prestigious publications in the world as far as knowledge of the human body is concerned.
At Proiser we know that the field of human reproduction has many unanswered questions. Findings that could clarify and facilitate assisted reproduction processes. Hence, we are attentive to each of the advances that occur in this regard. And that we value positively that publications such as the newspaper 20 Minutos echo these advances.
So that our followers can know them, we share a good part of that news.
The eggs are able to choose the sperm they attract
Human eggs are able to choose the sperm with which they want to combine. And they do it regardless of the relationship that people have with each other. It is not affective at all.
This is, at least, the conclusion reached by researchers from the Universities of Manchester University NHS Foundation Trust (United Kingdom) and Stockholm (Sweden) who work in this field together.
This selection, according to the investigations, is carried out according to quality criteria or by DNA. But this sperm isn’t necessarily from the partner.
A fact that qualifies what was known up to now and revolutionizes the procedures that have been developing in the assistance to conception. And it is that although we knew that eggs use chemical signals to attract sperm. Now we must add that these signals also serve to choose sperm. This behaviour varies according to the woman. And it is that, some eggs attract different types of sperm than others.
And all is done according to the quality or genetic compatibility that both cells share. In other words, the interactions between human eggs and sperm depend on the identity of the man and woman involved.
Advances to better understand reproduction
All these investigations shed light on some of the great questions of assisted reproduction processes. Especially, when they are failed and there is no proven physical explanation to support it. Thus, we can say that research on how eggs interact with sperm will bring advances in fertility treatments. This will allow us to continue developing systems that make them more and more efficient.
Excellent news for professionals in the sector like those of us who are behind Proiser, as we develop proposals, products and instruments to ensure that these processes are developed successfully.
And it is that although we thought that empathy should be between people, the reality is very different. And it is that at least what this study shows is that this choice continues after the sexual relations of the same. Since the choice of the ovum to attract according to the type of sperm is totally independent of who the woman’s partner is.
In any case, while these theories have just been developed, remember that in Proiser you will be able to find everything your laboratory needs for assisted reproduction processes. You just have to visit our website and get in touch with us. Your laboratory will be equipped with the best on the market and will achieve the best results.
