MACS (Magnetic Activated Cell Sorting) is an immunomagnetic technique allowing the selection of those spermatozoa that do not show signs of cell damage or death (called apoptosis), and therefore maintain their entire DNA intact.
Seminal quality is a crucial factor when it comes to achieving a pregnancy, since it affects both fertilization and subsequent embryo quality. There are different factors that affect semen quality and one of them is the presence of apoptotic sperm. These damaged sperm can be removed from the sample using this technique because their membranes contain markers that can be detected, thus obtaining a fraction that is free of them and, therefore, better quality.
This technique can be used with any kind of patient, but is mainly used with:
90% of patients who undergo an assisted reproduction treatment at IVI become pregnant.
97% of our patients recommend IVI.
IVI provides personalised care and support during all stages of treatment.
IVI is a pioneer in the latest assisted reproduction technology in order to present the best results.
We are not the most expensive choice. We offer the most treatment options in order to achieve the best results.
Our IVI assisted reproduction clinics are pioneers in the application of Magnetic Activated Cell Sorting (MACS), with results indicating an improvement of up to 10-15% in the pregnancy rate.
The MACS technique involves the use of antibodies bound to tiny biodegradable magnetic particles that have the ability to recognize apoptotic sperm, that is, damaged sperm that are not able to fertilize the egg.
The sample is passed through columns with a magnetic field, so that these apoptotic sperm cells are retained in the walls of the column.
Thus, the fraction we obtain only contains healthy spermatozoa with the best physiological qualities for use in assisted reproduction treatments.
