Oral Sex May Spread Common STD
Australian Study
Identifies Disease in Both Heterosexual and Homosexual Men
Jan. 6, 2006 -- Oral sex raises the risk
of a common sexually transmitted disease (STD) called nongonococcal urethritis
(NGU) in men, Australian researchers report.
NGU is a type of urethritis,
an infection of the urethra, the tube that carries urine from the bladder to
outside the
body. One of the most common causes is Chlamydia trachomatis infection, yet it
is underreported because a substantial number of people are not aware of their
infection and do not seek testing, according to the CDC.
Other less common
bacteria and viruses can also cause NGU.
Symptoms include:
- Pain
or burning during urination
- A discharge from the
urethra
A significant number of men do not experience symptoms; this can
contribute the continued spread of the STD.
NGU is common among men and
women. The Australian study only included men.
Oral sex was linked to
less common infectious causes of NGU in heterosexual men and men who have sex
with men. The researchers include Catriona
Bradshaw, MD, and colleagues.
Bradshaw works in Australia's
Melbourne Sexual Health Centre and the University of Melbourne.
The
study appears in The Journal of Infectious Diseases.
STD Study
Bradshaw's study included 636 men -- 329 with and 307 without symptoms of
NGU -- who were seen at the Melbourne Sexual Health Centre.
The men were
about 32 years old, on average. They completed surveys about their sexual
practices, gave urine samples, and got genital examinations. Those with NGU
symptoms also got a urethral smear, a medical test done to detect pathogens that
may cause the infection.
NGU was associated with receiving oral
sex. It was also associated with unprotected anal sex and unprotected vaginal
sex.
Several viruses were associated with NGU, including the herpes virus
that causes cold sores (HSV-1). However, herpes sores weren't needed for NGU to
spread. HSV-1 was strongly linked to giving oral sex and men who report having
sex with men.
The HSV-1 virus was more strongly linked to NGU than another
herpes virus, herpes simplex virus 2 (HSV-2).
Hidden Causes?
The researchers couldn't
always identify a virus that caused NGU. There may be viruses that cause NGU that
haven't been discovered yet, they write.
Treatment decisions should be
based on signs and symptoms associated with urethritis, not just tests done with
a microscope, note Bradshaw and colleagues.
The study is "a good interim
step in understanding this common and often frustrating syndrome," but more work
needs to be done to understand NGU, writes
editorialist H. Hunter Handsfield, MD.
Handsfield works in Seattle at
the University of Washington's Center for AIDS and Sexually Transmitted
Diseases, as well as the university's department of medicine.
The
findings raise the importance of oral sex as a source of bacteria and viruses as
the cause of this STD and indicate that we should broaden our search for other
infectious causes of NGU, the researchers conclude.
