Dr will most likely want to do another test to be sure. Things such as too long or too short abstainance, sample being left too long before being tested amongst other things can dramatically effect the results.
What was his count? 25% is quite low as the the minimum needs to be 50%. Thats not to say that you cannot get pg from that level of motility, just that it is unlikely (naturally pg that is).
In most cases of very low motility, IVF/ICSI is usually what is needed.
Best of luck to you and I hope that this next test shows a more promising result
