Risk of cytomegalovirus transmission by cryopreserved semen: a study of 635 semen samples from 231 donors.
BACKGROUND The hypothetical responsibility of sperm donation in cytomegalovirus (CMV) transmission to recipients and precautions to prevent this transmission are widely discussed. The aim of this French CECOS Federation study was to evaluate both the reality and the importance of the CMV risk due to donor sperm and the relevance of measures used to screen it. METHODS We conducted a prospectiv...
متن کاملCytomegalovirus detection in cryopreserved semen samples collected for therapeutic donor insemination.
The presence of cytomegalovirus (CMV) in semen was retrospectively evaluated in 178 cryopreserved semen samples obtained from 97 donors recruited by two sperm banks. Thirty-three (34.0%) donors were CMV-seronegative, 51 (52.6%) were CMV-seropositive and 13 (13.4%) had an unknown serological status. CMV was detected in sperm specimens by cell culture and polymerase chain reaction (PCR). CMV was ...
متن کاملThe effects of storing and transporting cryopreserved semen samples on dry ice
OBJECTIVE This study aimed to test the effects on sperm viability of transporting cryopreserved semen samples on dry ice. METHODS Twenty normozoospermic semen samples were cryopreserved and divided into five groups. The samples in Group 1 were immersed in liquid nitrogen throughout the experiment in cryogenic storage tanks; the cryopreserved straws in Group 2 were placed in a Styrofoam box co...
متن کاملTheoretical aspects of canine cryopreserved semen evaluation.
Evaluation of canine cryopreserved semen has the ultimate goal of determining if an individual frozen ejaculate will have acceptable fertility. This is difficult in that there is no accepted normal fertility for the dog. The fertility of the female also plays a crucial role in estimating the fertility of the male. Poor female fertility can make a fertile male appear less fertile. Variability of...
متن کاملSperm Nuclear Chromatin Decondensation Test : Its Applicability to Predict Fertility of Cryopreserved Semen Samples
The nuclear chromatin decondensation test (NCDT) detects the ability of the sperm chromatin to undergo decondensation following fertilization. The test does not have direct bearing with the fertilizing ability of the spermatozoa but only reflects the proportion of sperm that may swell following exposure to in vitro decondensing agents. The gross seminal parameters do not have any direct relatio...
