The diagnosis of gonorrhoea in males can be made from which of the following?

The diagnosis of gonorrhea in males can indeed be established through a combination of various methods, which is why the comprehensive choice capturing all three aspects is deemed correct.

A positive urethral smear is a critical diagnostic tool; it allows for direct visualization of the organism Neisseria gonorrhoeae when a sample is taken from the urethra. This method provides definitive microbiological evidence of the infection.

Symptoms are also a vital part of the diagnostic process, as many males present with signs such as dysuria (painful urination) or purulent discharge from the urethra. These clinical manifestations can guide healthcare providers toward further diagnostic testing and indicate an active infection.

Additionally, taking a medical history is crucial in clinical settings. Understanding a patient's sexual history, possible exposure to infected partners, or previous episodes of sexually transmitted infections can provide valuable context to support the diagnosis.

Combining these approaches—urethral smear, symptoms, and patient history—enhances diagnostic accuracy and helps healthcare professionals confirm gonorrhea efficiently in males.
