Weekly summary - 286/287/288th week -- Risk of taking off Propecia

I just read a post from hair loss help forum that discuss of the risk of quitting Propecia or Finasteride.
Many of us who taking Propecia will afraid the consequences not only before we taking it but if one day, we want to stop to take the medicine.
Old question that in our heart most likely, when you quit Propecia:
1. Will I lost my hair? Definitely or most likely Yes
2. How soon will I lost my hair? It depends from weeks to month, some shedding very much, some said not much different.
3. Can you use Rogaine to substitute Propecia once you stop it? Most likely not but I guess it helps.
4. Will I regain libido once I stopped? Most people will said yes but there are people that never recovered. The plus side is there are people who never lost their libido with or without Propecia, so which story you listen?
5. Will I loss my libido? If you never feel a decrease of libido when you are with Propecia, you may be affected.
6. Are your sperm still healthy after many years with Propecia? I am unsure since some said if affects lower sperm count (which I think is likely) but some claim (Merck is one of it) your body will reversible to affect. So once you quit, you are likely to be normal back but everything is just possible.

In the end, no conclusion. SO many possibility and I just think, why I am bald and not the majority guys....
