This paper describes results of mycoplasma organism and Mycoplasma hyopneumoniae detection in semen of boars. During routine examination of semen quality in 2015 and 2016, different percent of specific changes in the spermatozoa of 23 b oars were observed and these samples were subjected to mycoplasma detection. The se changes were manifested as frequent distal midpiece reflex abnormalities with sporadic coiled principal piece; but booth loops were filed with fine, net like /reticular form s ( “ entrapped pseudocytoplasmatic droplet ” ). Based on the observed morphological forms i t is suspected on the presence and influence of microorganisms, primarily of Mycoplasma origin . PCR and real time PCR molecular methods were examined in all suspected s perm samples. The presence of Mycoplasma spp was found in 15 samples, of which, Mycoplasma hyopneumoniae was found in 8 samples. In the remaining seven samples differentiation to other mycoplasma species were not carried out . This article is indicating t hat genital form of mycoplasma could manifest its effect on semen quality and this may be more significant than current literature data are indicating and recogniz ing as problem in boars. In the same time, i ts high incidence in suspected semen samples coul d be more stressed as a source of sexually transmitted infection. Further estimation of Mycoplasma influence on boar semen quality is needed.
