Diagnosis Of Conditions Accompanied By Penile Discharge

There are several different ways to diagnose an STD. Penile discharge urethritis is most commonly diagnosed by finding white blood cells on a urethral swab or urine sample. The color and consistency of the discharge alone does not help distinguish any non-specific urethritis from gonococcal urethritis. [5]

Gonococcal urethritis is diagnosed in 98% of men by microscopic examination of the discharge obtained from a urethral swab.
Development of more sensitive tests such as polymerase chain reaction and ligase chain reaction might allow for more precise diagnosis, especially in patients with no symptoms. [5] 

Treatment Of Conditions With Penile Discharge

Gonococcal urethritis

One of several antibiotics can be given as a single dose [5]:

• Ceftriaxone 250mg by intramuscular injection
• Cefixime 400mg orally
• Ciprofloxacin 500mg orally
• Ofloxacin 400mg orally.
• Doxycycline 100mg twice daily for seven days

Non-specific urethritis 

Typical antibiotic treatment includes doxycycline 100mg twice daily for seven days or a single dose of Azithromycin 1g if the infection is due to Chlamydia trachomatis. [5]

Prevention Of STDs

The most secure way of preventing sexually transmitted diseases is definitely sustaining from sexual intercourse. Another option is to be in a long-term monogamous relationship with an uninfected partner. 

Activities that carry a very low or no risk of developing a sexually transmitted disease are:

• Kissing
• Massage
• Masturbation
• Sexual stimulation using your hand on another person
• Oral sex on a man who is wearing a condom
• Oral sex on a woman who is wearing a dental dam or plastic wrap
