Spermatozoa elemental composition analysis reveals differences in sodium and potassium levels between fertile and infertile men. These elemental variations may offer future diagnostic potential for assessing male fertility.

Area of Science:

  • Reproductive Biology
  • Biochemistry
  • Andrology

Background:

  • Male infertility affects a significant portion of couples seeking fertility treatment.
  • Subcellular elemental composition of spermatozoa is crucial for function.
  • Previous studies have explored elemental content, but detailed regional analysis is limited.

Purpose of the Study:

  • To compare the subcellular elemental composition of morphologically normal spermatozoa from men with normal semen parameters versus those with oligozoospermia or asthenozoospermia.
  • To identify potential elemental biomarkers for male reproductive potential.

Main Methods:

  • Spermatozoa were collected from men attending an infertility clinic.
  • Subcellular elemental composition was measured in acrosome, nucleus, mid-piece, and tail regions.

  • Analysis compared samples from men with normal semen parameters against those with low sperm count (oligozoospermia) or low motility (asthenozoospermia).

    • Main Results:

    • Sodium and potassium levels were significantly lower in spermatozoa from men with abnormal semen parameters (oligozoospermia/asthenozoospermia).
    • Overall elemental distribution was similar between groups, but a non-significant trend towards higher total elemental values was observed in abnormal semen.
    • Highest elemental concentrations were consistently found in the nuclear and mid-piece regions of all analyzed spermatozoa.

    Conclusions:

    • Specific elemental differences, particularly lower sodium and potassium, are associated with male infertility.
    • Subcellular elemental analysis of spermatozoa holds promise as a diagnostic tool for evaluating male procreative potential.
    • Further research into elemental profiling could refine diagnostic capabilities in andrology.
