Zymot in Seville: high-precision sperm selection

At Viamed Fertility Institute, we know that for an assisted reproduction treatment to be successful, it is not enough to have sperm cells; we need the best ones. Until now, laboratories relied on mechanical methods to separate gametes, but technology has evolved. The Zymot technique represents the most natural and sophisticated way to choose the sperm cell with the greatest potential to help create a healthy baby.

From Viamed Hospital Santa Ángela de la Cruz, we offer you this microfluidic innovation, designed so that your Life Project has the best genetic foundation from the very first second.

What is the Zymot® technique and how does it help choose the “champion”?

Traditionally, laboratories use centrifugation to separate sperm cells. However, this process can generate oxidative stress, which may damage genetic material. Zymot changes the rules of the game: it is a microfluidic device that imitates the natural journey sperm cells take inside the woman’s body towards the egg.

It is, quite literally, an obstacle race. The Zymot chip contains a series of micropores that can only be crossed by sperm cells with the best motility and, most importantly, the best structural health. In this way, our outstanding team of professionals selects the “champions” organically, without chemicals or aggressive mechanical processes.

The end of fragmentation: why Zymot is vital for success

One of the greatest enemies of male fertility is sperm DNA fragmentation. If the sperm cell’s DNA is damaged or broken, the resulting embryo is much more likely to present abnormalities, which may lead to implantation failure or recurrent miscarriage. The Zymot technique acts as an exceptional biological filter. It has been shown that sperm cells able to swim through the microfluidic chip are those with intact and well-preserved DNA. By using Zymot, we help ensure that the embryo receives the correct genetic instructions to develop successfully.

Safety and excellence at Viamed Hospital Santa Ángela de la Cruz

Choosing Zymot at Viamed Fertility Institute is not just choosing a technique; it is choosing the safety of a highly complex hospital environment.

At our hospital in Seville, sample processing with Zymot is carried out in state-of-the-art laboratories under strict quality controls. The support of Viamed Salud guarantees that every sample is handled with absolute traceability by experts who understand that behind every process there is a dream to protect.

Who is Zymot recommended for?

Although it can be used in most IVF cycles, our medical team especially recommends it in the following cases:

Advanced paternal age

Where the risk of DNA fragmentation is higher.

Asthenozoospermia

Men with low sperm motility.

Unexplained infertility

When other tests do not explain previous failures.

Recurrent miscarriage

To minimise the male factor in pregnancy losses.

Poor embryo quality

When embryos have stopped developing in previous cycles.

Real benefits: more than selection, a better beginning

Scientific evidence supports the fact that the use of Zymot can significantly improve results:

Higher fertilisation rates

By using sperm cells with better penetration capacity.

Improved embryo development:

Embryos are healthier and reach the blastocyst stage with greater strength.

Reduced risk of miscarriage

By reducing the proportion of embryos with damaged DNA.

FAQs: frequently asked questions about Zymot in Seville

Zymot is a much more respectful and natural technique. Unlike MACS or centrifugation, it does not use magnetic fields or acceleration forces, which reduces cellular stress and better protects the integrity of the sperm cell.

It can be used in the vast majority of cases, as long as the semen sample has a minimum concentration of motile sperm cells to allow filtration through the chip.

Yes, because a normal semen analysis only measures quantity and visible movement, but tells us nothing about the internal DNA. Zymot helps ensure that, in addition to moving well, the sperm cell is genetically healthy.

Do not leave the selection of your future to chance
