Patient: hey... my liquefaction time of my spemen analysis is 30 min (borderline), is it normal ? can I take like Nacetyl cysteine to decrese time of liquefaction, or what can I do ? is N acetyl cycsteine taken without Dr, Prescription is good ? or may alterate my sperm Thanks a lot Doctor: Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.  The normal semen liquefaction time ranges from 20-30 min and anything above 60 min is dangerous and make the process of fertilization difficult, in your case i do not think that you should be worried about it. The main two reasons for increased liquefaction time is semen infection or dehydration. I would like you to share the complete details of your semen analysis so that i may rule out the infection. If there is no infection the the cause of increased liquefaction time would be dehydration and i would recommend you to increase your hydration status. Regarding n-acetylcystiene, studies has shown that it does improves the health of sperms but it has no documented effect on sperm liquefaction time and i would recommend you not to use it without doctors prescription.  Hope I have answered your query. Let me know if I can assist you further.
