The eggs are able to choose the sperm they attract

/in /by

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.

Spermtrack  counting chamber is the name given to the new counting camera that the ISAS brand has launched. It is a new product that we want to improve the work of seminal analysis , an area in which the company is a leader.

With Spermtrack the offer grows with a new tool that substantially improves the counting cameras that already existed in the marking . By following the semen droplet displacement procedure, The Spermtrack eliminates most of the disadvantages of the less efficient products on the market.

Another advantage is its design. A model that facilitates its use under the microscope and makes it even easier to clean, handle and store .

One of the most striking features of this element is that it can be customized by colors . Therefore, it is easier to identify the samples with which we are working and speed up the work process in this regard. It also allows you to engrave the identifying name on the bottom of the camera, for added security .

 

Spermtrack counting chamber: for humans and animals

Aware that it will be an element that will be used in many laboratories and for different purposes, the company has decided to launch it with two different capacities. Thus, we can find Spermtrack in 10 and 20 micron models.

The first model is a 10 μm deep chamber that is optimal for traditional human clinical testing . These are the usual measurements that we usually find in this type of camera.

The Spertrack 20 is a chamber with a capacity of 20 μm , following the latest recommendations in the WHO 2010 laboratory manual. An aspect with which its use is also extended for veterinary purposes . This greater capacity allows a greater natural freedom of movement of the sperm , a necessary peculiarity for this type of sperm samples.

Another feature to consider when it comes to Spermtrack is the reliability and security that comes with laboratory analysis. Therefore, the serial numbers on the lid and the chamber are independent, allowing full traceability of the sample as marked by ISO 13485 standards .

Finally, it should be noted that Spermtrack allows better visibility under the microscope . This is because this chamber is thinner than other similar products in the lab products industry.

This is because the light from the microscope’s condenser reaches the sample much more in focus, improving optical quality and avoiding the generation of common visual artifacts that appear in other similar devices. This makes it much easier to observe and study these samples in laboratories.

Therefore, with Spermtrack you gain in reliability, safety, visibility, organization, optimization of work, safety and reliability . Aspects that are causing many laboratories to rely on this new system for their projects. If you want to test its effectiveness and improve your performance, do not hesitate and contact us.

Not only will we expand the information we have collected in this article , but we will answer any questions that may arise in this regard and we will tell you how to get them. And all this simply by contacting us through the web or by phone. Don’t hesitate and make the leap to superior quality and work!

Thrumorph: the new technique of observing sperm morphology

/in /by

Trumorph is the name of a technique that is presented as the definitive mode of work in terms of observation of sperm morphology.

A system with which you will be able to obtain reliable data with which to carry out your research on sperm samples, in the best possible way. Who your lab, using this system, will be able to be more competitive and be able to respond to the needs of users faster than is usually done.

In order to know this system, its operation and advantages, we have written this article in which we want to develop a little its concept and philosophy.

⠀

Trumorph: what is it and what advantages it offers in the observation of sperm morphology.

Trumorph is a system that allows us to analyze the morphology of sperm from a semen sample of a person or animal. So thanks to it we can know all the data we need to work with sperm samples.
⠀
To achieve this, Trumorph comprises a device and a 40x/60 PH (-) lens. So, after placing a drop between the carrier and the conventional cover, the device raises the sample temperature to 45 degrees Celsius for 5 seconds, applying a slight pressure. This allows cells to be immobilized and easier to observe in the optical microscope. Which allows you to carry out your study without any problem more quickly because thanks to this system we have prepared the sample in just a few seconds.
⠀
What saves key time for this activity, as the shorter process of preparing sperm samples usually takes about 2 hours.
