While it seems that the rate of Chlamydia infection risk in women is higher than in men, the Chlamydia here is more common than any other male sexually transmitted disease, with millions of new reported cases each year. 
Chlamydia is a sexually transmitted infection (STI) caused by a tiny bacterium, Chlamydia trachomatis. In case of men suffered from Chlamydia, the bacterium will affect to inside the urethra, the tube through which men urinate and pass sperm; in women the primary infected site is on the cervix, which is the opening between the uterus and the vagina.
During unprotected sex these bacteria will transfer through genital fluids from one partner to the other. Unprotected anal sex, whether by gay or straight partners, also puts man at risk of contracting chlamydia.
Men with Chlamydia symptoms may experience:
- Irritation of penis – the tip and opening of the penis may feel itchy much or all of the time, or even become a sharper burning pain. There may be some reddishness or inflammation around the opening, but this is more often caused by scratching or rubbing the itchiness rather than by the infection itself.
- Painful urination – the penis may or may not itch or burn generally during the day, but upon urinating you may feel pain or even intense burning, sometimes making urination a very painful and dreaded ordeal.
- Frequent urination – you may begin needing to urinate more often than you used to.
For diagnosis and treatment, the only way to detect Chlamydial infections is by requesting a particular type of test . Both men and women, especially young group aged under 25, should be annually tested for Chlamydia, which is quite simple and it might be taken in the form of a urine sample or a swab from the cervix (in women) and urethra (in men). Once detected, the infection is very easy to cure with antibiotics.
Without treatments, men can have complications as serious as affection of sperm function and male fertility. Left untreated Chlamydia can be cause of inflammation in the testicles and sperm-conducting tubes (epididymo-orchitis) in men under the age of 35. Symptoms include pain and swelling in the scrotum. Chlamydia can also trigger joint inflammation in some men.
