Studies on the integration of hepatitis B virus DNA sequence in human sperm chromosomes. Clinical retrospective studies reported that compared with controls, HBV seropositive male exhibited lower sperm motility and total sperm count as well as poor morphology and sperm motility [ 1516 ]. However, our study showed that semen parameters were comparable between groups.
Adverse effects of hepatitis B virus on sperm motility and fertilization ability during IVF.
Presence of hepatitis B virus in oocytes and embryos: J Submicrosc Cytol Pathol. It has been demonstrated in vitro that HBV S protein has adverse effects on human sperm function with consequences for fertilization. Meanwhile, this aberration could also be found in 4.
Semen and hormonal parameters in men with chronic hepatitis C infection.
The presence and expression of the hepatitis B virus in human oocytes and embryos. To assess the contributions of different variables to pregnancy rate, we performed binary logistic regression. A total of couples undergoing for their first oocyte donation cycle were included in this study: Clinical hepatitis low sperm count was defined as identification of a gestational sac weeks after the positive pregnancy test. Our study showed that male HBV infection had little impact on the outcomes of these three steps, even we used oocyte donation as a model, which is a useful tool for studying external variables from men affecting assisted reproduction treatments.
