Assessment of male factor

Area of Science:

• Reproductive Medicine
• Andrology
• Infertility Diagnostics

Background:

• Male infertility assessment relies on World Health Organization (WHO) semen analysis methods established in the 1950s.
• Despite decades of research, established sperm function tests have not been integrated into routine clinical practice.
• Current semen analysis techniques lack the sensitivity to fully evaluate sperm function and predict fertility outcomes.

Purpose of the Study:

• To review recent advancements in sperm function and selection tests for male infertility.
• To assess the potential of novel techniques to improve upon or replace traditional semen analysis.
• To highlight the need for rigorous clinical evaluation of emerging sperm assessment technologies.

Main Methods:

• Review of recently developed sperm function and selection assays.
• Exploration of techniques including microfluidics, electrophoresis, hyaluronic acid binding, and high magnification selection.
• Emphasis on the necessity of randomized-controlled trials (RCTs) for validation.

Main Results:

• Several novel sperm function and selection methods have been developed.
• These new techniques offer potential improvements over conventional semen analysis.
• No new methods have yet been adopted into routine clinical practice.

Conclusions:

• Emerging sperm function and selection tests show potential for enhancing male infertility diagnosis.
• Randomized-controlled trials are crucial to validate these novel methods.
• Clinical integration of these advanced techniques could significantly improve fertility assessments and treatments.
