MRI scan on protate - does this affect fertility?

I'm soon going to have an MRI scan on my prostate - will this effect the quality of my sperm in any way ? I'm NOT so much afraid of infertility - I'm more concerned about the possible affect on any potential new life that might ensue if fertilisation occurs AFTER the MRI scan. In other words - is it possible that the MRI scan would negatively affect the health of any baby that might be conceived ?
