Abstrakt: The consequences of hepatitis B virus (HBV) infection for fertility are still unclear. Spermatozoa with decreased motility have been reported in HBV-infected patients. It has been demonstrated in vitro that HBV S protein has adverse effects on human sperm function with consequences for fertilization. In a case-control study design, 32 IVF cycles in couples with male HBV infection were compared with 64 cycles in non-infected couples, matched for age, time period, cycle rank and sperm parameters on the day of oocyte retrieval. Sperm motility before selection was significantly reduced in the HBV group (36.3 ± 11.6% versus 45.3 ± 14.4%,P = 0.003). A low fertilization rate (LFR) was more frequently observed in the HBV group (34.4% versus 15.6%, P = 0.036) and was associated with a decreased number of embryos available for transfer, although embryo quality on day 2 or 3 was not different.Implantation and pregnancy rates were comparable between groups. This study shows that HBV has a deleterious effect on sperm motility in vivo and that couples whose male partner is infected have a higher risk of LFR after IVF, a risk which is independent from the initial sperm motility.
