Summary

A Toggenburger buck with gynecomastia had normal testosterone and estradiol levels. Elevated prolactin was identified as the likely cause of the condition, with semen quality unaffected.

Area of Science:

  • Veterinary Medicine
  • Endocrinology
  • Animal Reproduction

Background:

  • Gynecomastia in male goats can be associated with hormonal imbalances.
  • Understanding the endocrine factors contributing to gynecomastia is crucial for diagnosis and treatment.

Observation:

  • A 3-year-old Toggenburger buck presented with clinical signs of gynecomastia.
  • Physical examination revealed enlarged mammary tissues in the buck.

Findings:

  • Karyotyping did not reveal any cytogenetic abnormalities.
  • Plasma testosterone and estradiol concentrations were within normal ranges when compared to controls.
  • Significantly elevated plasma prolactin levels were detected in the affected buck.

Implications:

  • Hyperprolactinemia is identified as the probable cause of gynecomastia in this case.
  • The condition did not appear to affect the buck's semen quality.
  • This finding contributes to the understanding of endocrine-related reproductive issues in male goats.
