Yes, Hepatitis B (HBV) can affect sperm. Specifically, the 'S' protein in HBV can negatively impact sperm.
How Hepatitis B Affects Sperm:
- Reduced Sperm Motility: The 'S' protein in HBV has been shown to reduce sperm motility, which is the sperm's ability to move properly.
- Decreased Fertilization Rate: The 'S' protein can decrease the rate of fertilization by sperm by over half.
- Potential Low Fertility: Some studies suggest that couples where the male partner has HBV may face a risk of low fertility, even after undergoing IVF (In Vitro Fertilization).
Impact on Fertility:
The effects of HBV on sperm can significantly impact a couple's ability to conceive. The reduced motility and decreased fertilization rate can make it more difficult to achieve pregnancy naturally.
Examples:
Imagine two couples are trying to conceive. In one couple, the male partner has Hepatitis B. In the other couple, neither partner has HBV. The couple where the male partner has HBV may experience more difficulty conceiving due to the effects of the virus on sperm motility and fertilization rates. IVF may be less successful as well.
