The sperms are exposed to a magnetic field – The sperms onto which the magnetic beads bind are trapped in the column. The sperms onto which the magnetic beads do not bind pass through- These are healthy sperms
Indications to use MACS
- Low sperm quality - motility and morphology
- Heavy smokers, varicocele etc.
- Patients with more than 2 cycles with unexpected poor fertilization
- Poor embryo quality/blastocyst rate
- Repeated miscarriages.
