Area of Science:

  • Reproductive Biology
  • Andrology
  • Sperm Morphology Analysis

Background:

  • Accurate sperm morphology assessment is crucial for male fertility evaluations.
  • The IVOS (Integrated Visual Optical System) aids in objective sperm analysis.
  • Standardization of slide preparation and staining is needed for consistent IVOS system performance.

Purpose of the Study:

  • To standardize slide preparation and staining for the IVOS system.
  • To enhance the efficiency and effectiveness of normal sperm morphology readings.
  • To evaluate the impact of preparation and fixation timing on results.

Main Methods:

  • Experiment 1: Evaluated five Diff-Quik staining procedures and assessed effects of slide preparation and fixation timing.
  • Experiment 2: Compared manual sperm morphology assessment time with IVOS computer analysis time.

  • Utilized semen samples from patients at the Reproductive Biology Unit, Tygerberg Hospital.

    • Main Results:

    • No significant difference was found between the five staining procedures (p = .60).
    • Slide preparation time (within 1h or >5h) and fixation time (immediate vs. 24h) did not significantly affect computer analysis.
    • IVOS system assessment time (4 min:39 s) was competitive with manual assessment (3 min:6 s and 3 min:53 s).

    Conclusions:

    • Standardization of staining procedures is vital for repeatability and comparability in sperm morphology analysis.
    • Immediate slide preparation after liquefaction and immediate fixation after air drying are recommended.
    • The IVOS system offers competitive assessment times for sperm morphology.
