Types of Sperm Movement
Motility % (PR)
Sperm swimming straight or in large circles, actively moving forward. This is the most important type for natural conception.
Target: ≥32%
Non-Progressive (NP)
Sperm moving but not going forward - swimming in small circles or only tail movement. Less helpful for fertilization.
Normal: 1-3%
Immotile (IM)
No movement observed. May be alive but not moving, or dead. High immotility requires vitality testing.
Normal: <60%
What Your Motility Results Mean
Normal Motility (≥32% Progressive)
Your sperm are swimming well! This indicates healthy sperm function and good chances for natural conception. Continue maintaining your healthy lifestyle.
Outlook: Excellent fertility potential from a motility perspective.
Mild Asthenozoospermia (20-31% Progressive)
Slightly reduced motility that often improves with simple lifestyle changes. Many men in this range still achieve natural pregnancy, though it may take longer.
Action: Implement lifestyle changes - expect improvement in 2-3 months.
Moderate Asthenozoospermia (10-19% Progressive)
Significantly reduced motility that may require both lifestyle interventions and medical support. Natural conception is still possible but may be challenging.
Recommendation: Combine lifestyle changes with fertility consultation.
Severe Asthenozoospermia (<10% Progressive)
Very low motility requiring medical evaluation to identify causes. May need assisted reproductive techniques, but identifying and treating the cause can sometimes restore motility.
Important: Seek fertility specialist evaluation promptly.
