Mecobalamin (Me-B 12) improved sperm production in oligozoospermic mice. Treatment increased sperm count, motility, and mature sperm output, suggesting enhanced testicular function.

Area of Science:

  • Reproductive biology
  • Pharmacology
  • Toxicology

Background:

  • Oligozoospermia, characterized by low sperm count, is a significant cause of male infertility.
  • Adriamycin-induced testicular damage serves as a model to study male reproductive dysfunction.
  • Mecobalamin (Me-B 12) is a form of vitamin B12 with potential therapeutic applications.

Purpose of the Study:

  • To investigate the effect of Mecobalamin (Me-B 12) on sperm production in a mouse model of experimentally induced oligozoospermia.
  • To quantitatively assess changes in sperm parameters following Me-B 12 administration.

Main Methods:

  • Oligozoospermia was induced in mice using adriamycin treatment.
  • Mice received oral administration of Mecobalamin (Me-B 12) at 1.0 mg/kg/day for 10 weeks.

  • Sperm production and quality were evaluated using Percoll density gradient centrifugation to analyze sperm distribution, motility, and count.

    • Main Results:

    • Mecobalamin (Me-B 12) treatment significantly increased sperm count and motility in oligozoospermic mice.
    • The percentage of mature, motile sperm with higher apparent density was notably enhanced.
    • Adriamycin-induced reduction in sperm parameters was ameliorated by Me-B 12 administration.

    Conclusions:

    • Mecobalamin (Me-B 12) demonstrates a positive effect on testicular function and sperm output.
    • Me-B 12 may hold therapeutic potential for improving sperm quality and treating male infertility associated with oligozoospermia.
