Well, I went through the most difficult period in my life and shortly thereafter started to shed quite a bit. To my Derm (also Father) it was textbook Telogen Effluvium. I just got back from lunch with him and he told me that it still doesn't fit the male pattern baldness profile. I am convinced that he is wrong and I have faced the fact that I am just losing my hair. Sometimes I think the shedding is slowing, but that may just be wishful thinking. I started Propecia on Feb.2 and don't know if its working or not, I guess it is too soon, but it definitely is not helping in the front, that I do know. It seems like everybody on this website has gone through periods of shedding and seen them stop so I figured I would see mine stop eventually, but it just isn't and we're approaching the 5 month mark. I am reluctant to get on minoxidil, but it seems I am doing pretty much everything else. I could deal with the hairloss if it weren't happening so damn fast. I know, have patience.
By the way, I am 34 and somebody here told me that when it hits you at that late stage it usually is not very aggressive, but I am receeding 1/4" every month with no end in sight. I have already been thinking about the day that I post here on HairLossTalk.com and say thanks to everybody and good luck, but my battle is over, I lost. If nothing changes it isn't that far away.
I also don't think you should get that concerned with all those biological changes you're experiencing, much of it seems somewhat normal.
