Claims ejaculate can have wellness benefit is usually restricted to thesleaziest kind of fake news program . However , a newspaper in a respected compeer - reviewed diary has ply grounds that exposure to semen gun trigger change that boost resistance to HIV . The inquiry could explicate some puzzle aspect of HIV transmission , but definitely should n’t be used as an excuse to engage in unsafe sex .
Professor Luis Montanerof the Wistar Institute remark reports that some sex worker in Puerto Rico tested negative to HIV despite say they did not consistently apply condom . Based on the incidence of HIV in the residential district , they had almost for sure been exposed to the computer virus many time .
In 2015 , Montanerpublished evidencethat frequent semen exposure triggers change in the vagina that increase HIV immunity . The idea that the primary medium for the transmission of the virus could also leave partial protection brings to mind the saying “ sinful claim require extraordinary test copy ” , and that paper was far from conclusive .
Now , Montaner has co - author a paper inNature Communicationsreporting what happened after distaff macaque were exposed to come twice a week . Some of the sampling include inactivated particles of the simian immunodeficiency virus ( SIV ) , a relative of HIV used by researchers to model the behavior of the human virus . After 20 weeks , the macaque , along with a control radical , were exposed to moo vaginal SIV dosage .
The semen - exposed monkeys were 42 percent less potential to be infected by the SIV than the controls . They also showed rock-bottom aspect of CCR5 receptors on the CD4 + T cells that are HIV and SIV ’s prey . The viruses target these receptors to oblige to and enter the cells , so fewer receptors could explain the reduced risk of infection . Moreover , semen exposure was relate with increase levels of the HIV - suppressing ingredient CCL5 in the cervix and vagina . Finally , exposure to come induced increases in vaginal tissue paper known to be associate with viral and bacterial fighting capacity .
" While HIV contagion has been with us for more than 30 years , this is the first study that account how semen pic over time could result in local tissue paper change that limit HIV infection in humans , " Montaner enunciate in astatement .
creature , even our fellow hierarch , are not always dependable guide to how the human body will behave . Nevertheless , the results are consistent with what Montanerpreviously reportedabout the immune organization of gender proletarian who had frequent condomless sexual activity compared to a control grouping .
A 42 percent reduction is still far below the aegis provided by condom and even the macaque who resisted the down in the mouth doses give in to higher SIV photo . Consequently , as a method acting of avoiding HIV , lots of unprotected sex is a non - starter . However , as a Spanish pointer to possible pathways for acquire drugs to prevent HIV transmission , the work could be priceless .
