Sperm Separation - ZYMOT
What Is Sperm Separation with the ZYMOT Method
The ZYMOT method is a modern sperm separation technology used in the embryology laboratory during assisted reproduction treatments, such as in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI).
Unlike traditional sperm processing methods, this technique imitates to some extent the natural sperm selection process that occurs in the female reproductive system, allowing the isolation of sperm with better characteristics for use in fertilization procedures.
How ZYMOT Technology Works in the Laboratory
ZYMOT technology is based on microfluidic devices (microfluidic chips) designed to allow the natural separation of sperm based on their motility and functional capacity.
Microfluidic Technology (microfluidics)
The ZYMOT device includes a specially designed system of microscopic channels through which sperm move toward a clean culture medium. Only sperm with good motility and adequate functional capacity can pass through these microchannels.
This process enables the selection of high-quality sperm without the need for intensive laboratory handling.
Natural Selection of Sperm
The device’s function imitates to some extent the natural barriers sperm encounter in the female reproductive system, such as the cervix and the uterus. In this way, sperm with better motility and a greater ability to progress toward the egg are selected.
Isolation of High-Quality Sperm
After the process is completed, the sperm fraction containing the sperm with the best motility and morphology characteristics is collected. These sperm can then be used in laboratory fertilization procedures, such as in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI).
Advantages of the ZYMOT Method in Sperm Separation
1.Reduction of Sperm DNA Fragmentation
Sperm DNA fragmentation is a factor that may affect fertilization and embryo development. With the ZYMOT method, sperm with better motility characteristics are selected, and these often show lower levels of DNA fragmentation.
2. Lower Exposure to Oxidative Stress
The centrifugation process used in some traditional sperm processing methods may increase the production of reactive oxygen species (ROS). ZYMOT technology avoids centrifugation, thereby reducing the likelihood of sperm exposure to oxidative stress.
3.Selection of Sperm with Better Motility
The method is based on the ability of sperm to move through microchannels. In this way, mainly sperm with good progressive motility are selected, which are considered more suitable for use in the fertilization process.
4.Avoidance of Intensive Laboratory Handling
Unlike some conventional sperm processing techniques, this method requires fewer processing steps. This helps reduce laboratory handling and limits factors that could affect sperm quality.
In Which Cases Can It Be Used
Increased Sperm DNA Fragmentation
In cases where increased sperm DNA fragmentation is identified, selecting sperm with better characteristics may be an important factor during the fertilization process. The ZYMOT method may help isolate sperm with a lower degree of DNA fragmentation.
Male Factor Infertility
In cases of male factor infertility, where problems such as reduced motility or abnormalities in sperm morphology are observed, the ZYMOT method can be used as an additional tool for sperm selection prior to fertilization.
Previous failed IVF attempts
For couples with a history of failed IVF attempts, additional techniques that may help optimize laboratory procedures are sometimes considered, such as sperm selection using the ZYMOT method.
Poor sperm quality
ZYMOT technology can also be used in cases where sperm quality is compromised, to select the spermatozoa with the best possible characteristics for use in the fertilization process.
How is the ZYMOT method incorporated into in vitro fertilization?
The procedure is performed on the day of fertilization, following sperm collection. The sample is processed using the ZYMOT device, and the fraction containing the selected sperm is then used in the laboratory fertilization procedures.
The method can be applied to various assisted reproductive techniques, such as:
Intracytoplasmic Sperm Injection (ICSI)
In intracytoplasmic sperm injection, a single sperm is selected by the embryologist and injected directly into the egg. The use of the ZYMOT method can help select sperm with better characteristics prior to the ICSI procedure.
In Vitro Fertilization (IVF)
In conventional IVF cycles, sperm are placed together with the eggs in the laboratory to facilitate fertilization. Sperm processing using the ZYMOT method can help select the sperm to be used in this procedure.
Safety and scientific data
ZYMOT devices are CE-certified and have been approved by the U.S. Food and Drug Administration (FDA) for laboratory use. In recent years, this technology has been studied at the research level in the context of assisted reproduction, with the aim of improving the sperm selection process prior to fertilization.
The use of this method serves as an additional tool in the embryology laboratory and is applied following an evaluation of the sperm characteristics and the specific needs of each treatment.
