Risk of transmission of sexually transmitted diseases by cryopreserved semen.

The increasing incidence of sexually transmitted diseases (STD) involves the risk of the transmission of these diseases by the artificial insemination. Therefore the cryotolerance of several microorganisms causing STD and the efficiency of penicillin of the cryoprotective medium (CMP) against Neisseria gonorrhoeae (N.g.) were investigated. The results have shown that penicillinase-producing N.g. (PPNG), genital mycoplasmas and Candida species survive the cryopreservation. Trichomonas vaginalis could not be recultivated after our temperature-time-regimen of the cryopreserving process. CPM with penicillin was unable to prevent a transmission of penicillin-sensitive N.g.

[Phagocytic activity of granulocytes after UV-irradiation].

The effect of UV-irradiation on three functions of human isolated granulocytes (viability, phagocyte activity and capacity to reduce nitrotetrazolium blue) was investigated. The phagocytosis appeared to be the most sensitive function. The number of phagocytic cells was decreased under UV-doses as low as 0.63 kJ.m-2. Cell lethality was increased under UV-doses 4.32 kJ.m-2 and higher. The capacity to reduce nitrotetrazolium blue was uneffected even at the dose as high as 10.17 kJ.m-2.
