It is coarse for people who have venereal chlamydia to also   modernize rectal chlamydia . In heterosexual cisgender adult female , this is more often caused byautoinoculation . They do n’t have to engage in anal retentive sex , the infection can simply pass from the vagina to the rectum .

The place is less clear for neat cis man . Their development of rectal chlamydia is considerably less likely to happen just by autoinoculation , so   researchers were interested in do work out if there might be other methods of infection . As reported in the journalSexually Transmitted Diseases , chlamydia might pass around to   the rectum via oral sexual urge .

A team led by Dr David Nelson from Indiana University in Bloomington enter 197 cis men at high risk of this sexually transmitted infection , who went to an STI clinic in Indianapolis , Indiana . Some of them had inflammation of the urethra , others did n’t . They produced urine samples and received a rectal mop . These were tested for chlamydia , as well as clap and another STI know asmycoplasma genitalium .

The 197 participant in this study complete a questionnaire that   asked about their symptoms , sexual orientation , and both their late unwritten and anal retentive intimate demeanor as well as throughout their lifetime . In the radical , there were 135 straight   man .

Out of these , 84 reported to have perform cunnilinctus but have never experienced any eccentric of anal retentive receptive doings . Only two people in this radical had a rectal contagion of chlamydia , and given their sexual history , the team debate that unwritten sexual practice might be a peril factor when it total to rectal chlamydia .

It could be argued that give way the ego - reported nature of the questionnaire , it ’s potential that the two people who contracted the transmission were   less than sincere . Many heterosexual men run to be unsure when it comes to their enjoyment of many soma of anal retentive drama , whether it is rim , fingering , or even nail .

While it is impossible to confirm if they were 100 per centum solemn , the team did not find rectal gonorrhea or mycoplasma genitalium in unbent men . The statistic were slightly dissimilar for the rest 62 hoi polloi , who either identify as gay or bisexual person . These men partake in in anal receptive conduct over their lifetime and they had a higher prevalence of all three infection .

It is also important to consider that it ’s long been suspected that chlamydia can   exist in thegastrointestinal tract , which   strengthens the idea put forward in this cogitation .
