Value of semen on finasteride?

Just wondering if any of you guys have done any blood or other tests to see whether the usage of topical fin can have a big impact on semen?  And has anyone tried to conceive successfully while on topical fin, any issues any thing? 

Yes, many men on finasteride develop a waterery semen with a decreased volume. A family member of a friend of mine took finasteride, had watery semen and a low sperm count, and made two nice babies.
