Sperm Testing in Assisted Reproductive Technology: Diagnosis and Outcome Prediction.

Infertility is a major global reproductive health challenge with significant social consequences, affecting an estimated 1 in 6 couples worldwide. Declining sperm quality represents a key contributing factor, making sperm analysis essential for diagnosing male infertility. Beyond conventional semen analysis, advanced assessments such as sperm DNA fragmentation testing and acrosome function evaluation have become standard diagnostic tools. Meanwhile, new technologies-such as 3D sperm imaging, high-precision microscopy, and genetic sequencing-are transforming sperm evaluation by analyzing movement, structure, function, and genetics in detail. These technological advancements enable two synergistic clinical improvements: (1) Deeper mechanistic understanding of sperm physiology via behavioral observation and molecular characterization, and (2) Enhanced sperm selection for assisted reproductive technologies (ART) through precision screening. The integration of interdisciplinary approaches-combining andrology, bioengineering, and computational biology-promises to accelerate the translation of novel sperm analysis platforms into clinical practice. This paradigm shift ultimately aims to elevate ART success rates while establishing evidence-based diagnostic frameworks for male infertility management.
