The presence of Gram-negative diplococci and pus cells in a male urethral discharge is highly suggestive of gonorrhoea, which is commonly caused by the bacterium Neisseria gonorrhoeae.

Chlamydia is caused by the bacterium Chlamydia trachomatis, which typically presents with a clear discharge rather than a purulent exudate. Genital herpes is a viral infection caused by the herpes simplex virus, which would not be detected on a Gram stain. Urinary tract infections are caused by a variety of bacteria, but the presence of Gram-negative diplococci and pus cells is more indicative of a sexually transmitted infection such as gonorrhoea.
