Final answer:
Males should keep their nails trimmed by regularly cutting or filing the free margin of the nail and maintain good hygiene by washing hands thoroughly, including using a nail brush to clean under the fingernails.
Step-by-step explanation:
Males should keep their nails trimmed to maintain good hygiene and prevent the accumulation of dirt and germs. The process involves cutting or filing the free margin, which is the part of the nail that extends beyond the tip of the finger or toe. While trimming nails is a straightforward task, it's essential to do it properly to avoid injury and maintain nail health. Regular hand washing and cleaning underneath the fingernails are also crucial for personal hygiene. It is recommended to use a nail brush when washing hands to remove debris and microorganisms from under the fingernails effectively.
In the context of personal hygiene, keeping one's nails trimmed is part of a broader set of practices aimed at maintaining the health of the reproductive stem. This includes keeping the genitals clean and avoiding contact with body fluids such as blood or semen. For males, regular hygiene practices also extend to monthly self-examinations for early detection of health issues.
