ABSTRACT
Despite years of research, numerous questions persist regarding the most effective sperm selection techniques. Frequently, new methods have gained popularity without thorough, extensive trials demonstrating their benefits. It is evident that there is no universally applicable solution, and it remains uncertain whether any of those techniques are genuinely advantageous in specific circumstances. The present chapter offers a thorough examination and evidence-based evaluation of existing methods, including both established practices and experimental approaches. In order to make progress, it is imperative to initiate and carry out multicentre clinical trials that can provide insights into the effectiveness of these techniques in terms of scientific, clinical, and financial outcomes.
