Most of the cases of liver injury are associated with the use of acetaminophen at doses that exceed 4000 milligrams per day, and often involve more than one acetaminophen-containing product. 1  VICODIN, VICODIN ES, and VICODIN HP should not be used if you are allergic to hydrocodone or acetaminophen.
Re: Non-Ejaculation. The only way I can see is in my eyes, and understand I am no doctor that a man can orgasm without ejaculation when masturbating and not during other acts is excess. When a man has a allot of sex in a short period of time, he may have a dry orgasm. It is possible, I think every man has had at least one.
In some cases, varicocele can cause azoospermia, or the complete lack of sperm in the ejaculate (see HERE for more information about azoospermia). Since varicoceles are so common and since they usually go undetected throughout life, likely around 80% of men with varicoceles are able to conceive with their partners without any medical intervention.
