ICSI involves the injection of a single sperm into an oocyte with a sharp micropipette. Injecting a sperm with DNA fragmentation (i.e., physical breakage of the DNA double strands) into the oocyte deterministically lowers the IVF fertilization rate \\[1\\]\\[2\\] and increases the miscarriage rate \\[3\\]\\[4\\]. Since the invention of ICSI in 1992, single sperm selection in ICSI has been made manually by embryologists, who select sperm by qualitatively choosing sperm with "good" motility and/or morphology based on their empirical experience. This involves significant subjectivity and inconsistency. We have developed a robotic system to select sperm with low sperm DNA fragmentation. Automated sperm selection also eliminates the subjectivity and inconsistency in manual sperm selection. The system consists of a camera to acquire images of sperm and a software to analyze the images. Embryologists select sperm by observing the same sperm characteristics as in the software criteria (e.g., speed etc.), but the software provides a more accurate and quantitative measure of sperm characteristics, thus ensuring the selected sperm have low DNA fragmentation.', 'detailedDescription': 'Intracytoplasmic sperm injection (ICSI) is one of the standard clinical treatments for infertility.
