TESA - Testicular Sperm Extraction Worldwide

Micro tesa

At North Cyprus IVF Center, we are able to offer another scientific break-through in IVF treatments, known as the "Integrated Microfluidic Chip". This system is designed to allow only the motile sperm with DNA integrity to pass through the microchannels of the chip. In a way, the sperm cells need to undergo a microscopic obstacle course in order to reach the other end of the chip. This increases our chance to use the sperm cells that are most likely to successfully fertilize the eggs.It uses no chemicals or centrifugation, meaning, the technique does not add any stress to the sperm cells while doing its job. Biologically, in natural conception, sperm cells swim through a variable fluidic environment in the female reproductive system with watery micro-channels that help guide them to the egg. The idea is to mimic what happens naturally, which is known to minimize the risk of genetic abnormalities as a result of natural selection. The integrated microfluidic chip for sperm selection is an ideal method for patients with sperm related problems. The main group of patients who can really benefit from this technology are those whose embryos fail to develop beyond a certain stage of development, due to likely genetic problems with the sperm.  It has been shown that sperm samples with high DNA defect are associated with lower blastocyst formation and lower implantation rates as a result. This is due to the fact that sperm cells empty their genetic content into the egg a few days after fertilization.  Therefore, even though there is fertilization, embryos will stop growing after a few days when there is a DNA defect with the sperm cell that has fertilized the oocyte.  This is precisely why this current technology is an important breakthrough which can possibly reduce IVF failures by a large degree.
