Automated Sperm Immobilization for Intracytoplasmic Sperm Injection [PDF]
IEEE Transactions on Biomedical Engineering, 2011 Sperm immobilization is a requisite step in intracytoplasmic sperm injection (ICSI). Conventionally, sperm immobilization is performed manually, which entails long training hours and stringent skills. Manual sperm immobilization also has the limitation of low success rates and poor reproducibility due to human fatigue and skill variations across ...
