At Dr. Aravind’s IVF – Tanjore, we are committed to offering the most advanced and personalized fertility care. That’s why we provide Magnetic-Activated Cell Sorting (MACS) — an innovative sperm selection technique that helps isolate the healthiest, most viable sperm for assisted reproduction. As the Best IVF Center in Tanjore, we combine cutting-edge lab science with compassionate care to support your journey to parenthood.
MACS is a powerful laboratory method that uses super-tiny magnetic beads coated with antibodies to detect and remove sperm cells showing early signs of programmed cell death (apoptosis). These beads bind to a marker called phosphatidylserine, which flips to the surface in dying sperm. When the sperm sample is passed through a magnetic column, the “tagged” apoptotic sperm are held back, letting the healthy, non-apoptotic sperm pass through.
Why Choose MACS at the Best IVF Center in Tanjore?
- Improved Sperm Quality: MACS helps remove damaged or dying sperm, enriching the sample with sperm that have better DNA integrity.
- Better Reproductive Outcomes: Clinical studies show that MACS-selected sperm can boost fertilization, increase pregnancy rates, and reduce miscarriage risk. In particular, research suggests a potential improvement in live birth rates when MACS is used for men with high DNA fragmentation.
- Tailored for Male Factor Challenges: This technique is especially beneficial for men with high sperm DNA fragmentation, apoptotic sperm, or previous failed IVF/ICSI cycles.
- Safe & Non-Invasive for Sperm: MACS is performed in the lab without harming the selected sperm — it doesn’t involve surgery, and it's compatible with IVF or ICSI.
How the MACS Process Works at Our Clinic
- Collection: A semen sample is taken and initially processed using standard methods (like density-gradient centrifugation).
- Magnetic Sorting: The sample is mixed with magnetic beads that bind only to apoptotic sperm; then passed through a magnetic column.
- Selection: Healthy, non-apoptotic sperm pass through the column and are collected for use in ICSI or IVF.
- Use in ART: These selected sperm are then used for fertilization, improving the potential for generating healthy embryos.
Who Can Benefit Most from MACS?
- Couples dealing with male infertility related to high sperm DNA damage
- Patients who’ve had recurrent IVF or ICSI failures
- Men with a history of recurrent miscarriage where poor sperm quality may be a factor
- Those looking to maximize embryo quality and increase chances of successful pregnancy
