At Viamed Fertility Institute, we know how frustrating it can be when, despite a semen analysis showing good results, embryos fail to develop or fertilisation does not occur. Often, the problem is an \u201cinvisible\u201d male factor: sperm cells that appear healthy under the microscope but have begun a process of programmed cell death known as apoptosis. <\/p>

The MACS technique is the technological solution that allows us to act as an \u201cintelligent filter\u201d, using magnets to separate sperm with the best potential from those that are not viable for creating life.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

What is the MACS technique and how does the \u201cmagnetic filter\u201d work?<\/h2>

MACS stands for Magnetic Activated Cell Sorting. To explain it simply, imagine passing the semen sample through a high-precision magnet that only captures the \u201cwounded soldiers\u201d. <\/p>

We use molecules called annexin V columns, which bind specifically to the membrane of sperm cells that are beginning to degrade, a process known as apoptosis. When the sample passes through this magnetic filter, the damaged sperm remain attached to the magnet, while healthy sperm, with an intact membrane and well-preserved DNA, flow freely and can be used for fertilisation. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
