Sperm sorting (MACS)

MACS or annexin columns is a sorting technique that makes it possible to select the spermatozoa with the best characteristics to be used in assisted reproduction techniques, improving the possibilities of achieving a pregnancy.

With the sperm training, we manage to separate the spermatozoa progressively motile from the rest in the sperm sample to increase the percentage of good quality spermatozoa with fertilization capability.

With MACS, we are able to retain motile spermatozoa with DNA damage in one column, thus increasing the percentage of good quality spermatozoa in the sample, enhancing the fertilization rate in the cycles with good quality embryos.

It is recommended in couples with severe male factor, with prior failures in IVF treatments, and in those whose prior studies show a high percentage of spermatozoa with fragmented DNA.
