I want information about gonorrhea and chlamydia

Chlamydia and gonorrhea, are bacterial infections transmitted through vaginal, anal and oral sex or contact with semen, vaginal fluids or anal secretions of infected people. They are very common diseases, affecting both men and women. However, once detected, they are easily treatable with antibiotics.

Risks & route of transmission

The most common route of chlamydia and gonorrhoea transmission is oral sex (according to our experience in Open House). Chlamydia is the most frequently detected infection in Open House.

The risks of transmission of gonorrhea and chlamydia in any type of sex (oral, vaginal or anal) is 40 to 60% by contact, if the person with whom we have had sex is infected.

Usually asymptomatic, but in some cases from the 3rd week of contact there may be stinging on urinating or abnormal fluid from the vagina, penis or anus.

People who have symptoms, be between day 2 and 10 of infection. It can cause abnormal mucus or pus in the genitals and in women, abdominal pain, fever and irregular menstrual bleeding.

Although many people infected with chlamydia or gonorrhea have no symptoms, if you have any of the following, you should consider testing:
In men, stinging on urination, burning, itching, discharge from the penis;
In women: burning or painful urination, altered discharge, pain during sex.
For both sexes: sore throat, tonsillitis, pus in the throat, rectal secretions, rectal burning or pain, abnormal feeling with stools.

  • According to Open House, 60% of Chlamydia infections in men (in the urethra) have no symptoms and 30% of cases of gonorrhea. Multiple scientific publications support this figure.
  • In the cervix and  throat infections 90% of show no symptoms.
  • You can only be 100% sure of not having Chlamydia or Gonorrhea by doing tests.
Treatment & prophylaxis

Open House fully complies with national and European guidelines in the treatment of gonorrhoea and chlamydia. We chose the right antibiotic on a case by case basis. Treatment may consist of a single dose or a course of antibiotics.

Outcomes in Open House
At Open House we successfully treat 99.5% of all gonorrhoea or chlamydia cases in house. Only 0.5% of cases get referred on to other specialists.
If you have had high risk sex for gonorrhoea or chlamydia in the last 3 days, there may be the possibility of administering prophylactic antibiotics. This is not an option for everyone and is decided on a case by case basis. Get in touch with us if you think you might be a candidate.
At Open House, whenever we have used prophylactic antibiotics, 100% of all patient were still negative in tests performed thereafter.


Long term consequences

Chlamydia is a major cause of infertility
If you are a man and have oral sex or penetration without a condom and you get infected with these bacteria, you can transmit them to another woman without realising it. In women, these infections can be very serious because they cause systemic infections, or can damage the uterus and Fallopian tubes. They are the cause of 20% of female infertility.

Chlamydia and gonorrhea, vehicle for HIV
The presence of chlamydia and gonorrhea in the throat, urethra, rectum or cervix can act as a catalyst for HIV transmission. For this reason, at Open House, if you test positive for one of these infections we will always recommend that you do an HIV test as a precaution.

I want information about other related infections

There are other infections that may cause similar symptoms to gonorrhoea and chlamydia. However these ones are not included in the normal check ups because it is only recommended to look for them and to treat them in those cases in which they are provoking symptoms.

  • Mycoplasma genitalium
  • Mycoplasma hominis and ureaplasma urealyticum
  • Trichomonas vaginalis
  • Urethritis and prostatitis
  • LGV
  • Do you have symptoms? You can do other tests
Mycoplasma genitalium

Mycoplasma genitalium is such a small and strange bacteria that we can barely detect it in routine tests. There are very few laboratories in Spain that can detect it. It produces EXACTLY the same infections as gonorrhoea and chlamydia (in the cervix, urethra and rectum) but if it decides it is going to be a silent infection, it does not cause any damage.
It has very slow incubation (2 to 6 months) and so it is common to not remember who gave you the infection. We don’t see it transmitted in oral sex, only in vaginal or anal sex, and symptoms are usually very obvious compared to gonorrhoea and chlamydia.
If we truly suspect this infection (all the symptoms but gonorrhoea and chlamydia negative) we initiate a specific treatment protocol as it is very resistant to antibiotics. It is one of the reasons that someone should never try to treat themselves with antibiotics to try to avoid testing.
Open House will be able to detect Mycoplasma genitalium and also say whether it is a resistant strain or not by 2019 when we finally acquire a long-awaited test.

Mycoplasma hominis and ureaplasma urealyticum

Before giving more details about these infections you should know that they are not exactly like gonorrhoea and chlamydia in the sense that if they are silent (without symptoms) they almost never do any damage both in men and women. Many doctors don’t even treat these infections when they are detected by chance, considering them to be part of the bacterial flora. However, it has been shown that the presence of these infections can increase the risk of catching HIV. Therefore, in Open House we always recommend the eradication of these bacteria in women.
We find these bacteria in about 30% of the adult population (vagina in women and urethra in men)
They are only transmitted in vaginal sex.
They do not do any other damage if they are silent.

Trichomonas vaginalis
  • Trichomonas vaginalis is a parasitic infection which is silent in about 50% of cases.
  • When it decides to produce symptoms, it is associated with vaginal itching and in men, urethral itching.
  • Chronic trichomonas in men can be a risk factor for developing prostatic cancer.
Urethritis and prostatitis

Data on our clinical experience with urethritis or prosatitis in men:
Cases of urethritis or prostatitis managed: 5500
Clinical success in the treatment of urethritis or prostatitis: 98.2%

Other causes of urethritis in men
Urethritis (inflammation of the urethra, the tube inside the penis) is common after sexual contacts. The symptoms of stinging inside, when you pee or on the tip of the penis may indicate urethritis. In the previous section you can read about causes such as gonorrhoea, chlamydia, mycoplasma and ureaplasma as bacterias which may cause urethritis, but there are other culprits.

Non-specific urethritis
: when a man clearly has urethritis but the tests are negative, we call this situation non-specific urethritis. It usually responds well to a particular antibiotic. A night out drinking with plenty of sex: After a night of heavy drinking that ended up with good sex, often we see urethritis which is nothing to do with bacteria, rather dehydration, trauma and chemical reactions to condoms. However, if the sex was unprotected, we recommend looking for infections first. Stress is also a cause of urethritis. Urethritis as a symptom of an underlying problem: Sometimes, symptoms of urethritis are not due to a problem of the urethra per se, rather there could be a urine infection, an imminent outbreak of herpes irritating nerves or infection in the prostate.


Lymphogranuloma venereum – the superchlamydia

Up until about 10 years ago there had only ever been seen about 100 cases of this serious infection in Spain. In recent years that is has gone up by about 500%. There is not a great deal of practical advice about this disease so Open House will share our thoughts with you here. It is of particular importance to men who have sex with men, who practise fisting or are HIV positive. It is produced by an agressive strain of chlamydia that invades the lymphatic system and can dissolve tissue and glands in the pelvis. Transmission in fistiing occurs from one persons rectum to another. In anal sex, it is transmitted from the penis to the rectum and vice versa. However, just like in other chlamydial infections, there are people who are silent carriers. A urethral infection can produce abscesses in the glands and in the rectum it can cause permanent damage. Key messages: if you have been diagnosed with urethral chlamydia and your glands are very painful, or if you have a rectal chlamydial infection that has relapsed, we should consider the possibility of lymphogranuloma and therefore a specific treatment.
