What does the letter "M" represent when describing the sex of an animal?

The letter "M" in veterinary terminology is commonly used to represent "Male" when describing the sex of an animal. This designation is crucial for identifying the biological sex of animals, especially in clinical settings, breeding, and when establishing health records. Accurately denoting sex is important for procedures such as spaying/neutering, understanding reproductive health, and managing behavior.

The other options do not accurately represent the conventional use of "M." For example, "Male/Female" would typically be denoted as "M/F" or "MF," while "Mixed" and "Minor" do not correspond to standard representations of animal sex in veterinary contexts. Understanding these definitions helps veterinary assistants communicate effectively and maintain accurate records.
