Hey there.
Here are the values of a german user (born 1984) who used Finasteride from April 2005 till June 2007. (age of 21-23)
Hormones
Hormone-Test early 2007 (on propecia for 2 years, still on it)
Testosteron: 4,69 ng/ml (3,5-8,6)
Prolactin: 14,10 ng/ml (<15)
SHBG: 34,90 nmol/l (13-71)
DHT: 271 ng/l (250-1000)
FSH: 2,72 mlU/ml (1-7)
LH: 4,07 mlU/ml (1,5-9,3)
DHEAS: 3,0 mg/l (1,6-4,5)
Hormone-Test early 2009 (about 2 years after quitting)
Testosteron: 6,66 ng/ml (3,5-8,6) -> 42% INCREASE!
Prolactin: 147 mU/l (<354) ->equals 6,94 ng/ml (<15) -> 50% DECREASE!!!
FSH: 2,9 mlU/ml (1-7)
LH: 3,3 mlU/ml (1,5-9,3)

Spermiogram
Spermiogram early 2007 (2 years finasteride, still on it)
- 40 Million sperm/ml (Norm >20 Mio/ml, average ca. 60 Mio/ml)
- mobility:
12% fast progressive sperms (Category A)
8% progressive (Category B)
Attention: This is seen as a pretty BAD Mobility!
Spermiogram early 2009, (2 years after quitting finasteride)
- 78 Million sperm/ml
- mobility:
23%: fast progressive (Category A)
6%: progressive (Category B)
Urologe says mobility still not ideal, but shouldn't make problems now anymore.
Summary:
- Testosterone raised a lot after quitting, prolactin decreased strongly -> Good for Libido.
- Spermiogram showed MUCH BETTER values AFTER quitting, almost doubled amount, Highly increased Mobility.
So there you have it folks. Propecia can affect the sperm quantity AND quality /mobility.
Of course, somepeople will show up and say "Look this is 1 case in a million". Yeah right. This is about the first case that someone has done a before and after spermiogram and posted it into a hair loss-board, and it's coincidence that he's one of the 1.000.000 who had decreased sperm count and bad hormonal balance right?
