We have conducted a comparative analysis of developing human embryos in the course of in vitro fertilization (IVF) as a method of sterility treatment of two groups of patients: herpes simplex virus (HSV) was detected in the fraction of motile sperm of male partners in group I (n = 28) and no HSV was found in sperm in group II (n = 103). W assessed number of fertilized ova, embryos during cleavage, and blastocysts as well as such parameters as frequency of implantation and frequency of pregnancy in IVF cycles. It was established that the presence of HSV in spermatozoa did not affect the efficiency of fertilization or cleavage of zygotes. At the same time, in cases of virus-infected male gametes, the frequency ofblastocyst formation was two times less (p = 0.015), and the frequency of embryo implantation and pregnancy was, on average, five times lower (p = 0.01 andp = 0.016, respectively). Based on the obtained results, a conclusion was made about the negative influence of HSV-virus in male gametes at the early stages of embryo development and the frequency of achievement of pregnancy in respect to the methods of assisted reproductive technologies (ART). |
