[Flagellar anomalies in routine spermatozoa cytograms]
1Unité de médecine de la reproduction, Hôpital Saint-Antoine, Paris.
Summary
This study introduces two new flagellar anomalies, thick and irregular, in semen analysis. Including these in routine morphological assessments can improve pregnancy chance correlation and diagnose severe asthenospermia in infertile patients.
Area of Science:
- Reproductive biology and andrology.
- Spermatozoa morphology and function.
Context:
- Routine semen analysis often overlooks flagellar abnormalities.
- Existing French classification includes four flagellar anomalies.
- Subfertile patients exhibit various flagellar defects impacting fertility.
Purpose:
- To describe two novel flagellar anomalies: thick and irregular.
- To advocate for the inclusion of these anomalies in standard semen morphological classification.
- To enhance the diagnostic accuracy of semen analysis for subfertility and infertility.
Summary:
- Two new flagellar anomalies, thick and irregular, were identified in approximately 5% of spermatozoa from subfertile patients.
- These anomalies, alongside existing classifications, are crucial for precise morphological analysis.
- Accurate identification aids in correlating sperm morphology with pregnancy outcomes.
Impact:
- Inclusion of these anomalies improves the correlation between precise morphological analysis and pregnancy chances.
- Facilitates easier detection of severe asthenospermia in infertile patients during routine semen analysis.
- Contributes to a more comprehensive understanding and assessment of male factor infertility.
