hard to say. I started taking it when I was around 23 / 24. Only thing I noticed is that it retarded my beard / body hair development. No issues on the sexual sides.
And it is all a guess, because, how can I know it affected my beard growth (I have little facial hair) since it never happened? Was it suppressed by finasteride or it would be like that anyways?
My guess it slowed it down was because I stop taking it for 4 months (being 38 yo) and my beard started to come like crazy - never had this before. Some hairs on my chest started to pop out too.
It would probably halt and/or reverse your hair loss. That's what it did for me. Same hairline from 23 to 38. Quit for a while, receded a lot. Got back, hairline regrew (took ~5yrs to regrow my temples). Quit a second time, receded again.

Now, you want my HONEST opinion on all this finasteride thing?
If I only knew how the drug worked, its effects on hormones and prostate.. I would not take back then, would just buzz my head very low and go lower each year.
Why? Well now, I hate the idea of having to stick with the drug or go totally bald in less than 1 year, instead of 5 or 10 in the natural route. It's a shock.
And, I don't like the idea of what it could have done or will do on my prostate. What if it up-regulated my body, and now it's super sensitive to DHT, to the point that if I stop, my body will go crazy and my prostate start to age and grow in a matter of months, and give me a ****ing cancer? Should I stick with finasteride, since my body is "used to it"? If so, won't the drug give me a cancer? **** man, I want to live more than 50 years.
Honestly, I am stressed as ****, because nobody knows the answers to my questions. Just because nobody has been using the drug for a lifetime yet. Maybe we will all be ****ed, maybe not.
Sorry about the depressing post. Just my current thought on all this.
And, yes, I resumed my finasteride intake.. 0.5mg. Will do it for a couple years, then try to tapper off during a whole year, til I am taking super-micro doses. Because when I quit cold turkey last time, my hair almost fell all at the same time and my prostate gave me issues...
Good luck with your decision.
