Summary

This study found higher malondialdehyde levels and altered trace element concentrations in semen from men with low sperm count or motility. Lipid peroxidation may contribute to reduced sperm motility.

Area of Science:

  • Reproductive Biology
  • Environmental Toxicology
  • Clinical Chemistry

Background:

  • Sperm quality is crucial for male fertility.
  • Trace elements and oxidative stress markers like malondialdehyde (MDA) may influence sperm parameters.
  • Understanding these relationships is vital for diagnosing and potentially treating male infertility.

Purpose of the Study:

  • To measure copper, iron, zinc, and MDA concentrations in human seminal plasma.
  • To correlate these levels with sperm count and motility.
  • To investigate the role of trace elements and lipid peroxidation in male infertility.

Main Methods:

  • Atomic absorption spectrometry was used to quantify copper, iron, and zinc.
  • High-performance liquid chromatography (HPLC) measured malondialdehyde concentrations.

  • Seminal plasma levels were correlated with sperm count and motility in normospermic and infertile men.

    • Main Results:

    • Significantly higher MDA concentrations were found in asthenospermia and oligoasthenospermia compared to normospermia.
    • Elevated copper and iron levels, and lower zinc levels, were observed in men with abnormal sperm parameters.
    • A negative correlation between MDA and sperm motility was noted in abnormal groups; no direct associations were found between trace elements and MDA.

    Conclusions:

    • Alterations in seminal trace element concentrations may be linked to impaired sperm quality.
    • Lipid peroxidation, indicated by MDA, appears involved in the decline of sperm motility, independent of seminal copper, iron, or zinc levels.
    • These findings suggest potential biomarkers for male infertility and avenues for further research into therapeutic interventions.
