Dutasteride causes persistent infertility in men
-
This study showed that even after discontinuation of dutasteride for 6 months, men that took it long-term still show signs of infertility like decreased semen volume I and motility.
If that is true for dutasteride than it's probably true finasreride as well, since they share the same mechanism of action.
"Long-term use of dutasteride may lead to male infertility by persistently impairing semen volume and sperm motility."

I have previously posted studies showing finasteride/dutasteride can cause penile fibrosis, down regulation of the androgen receptor and upregulation of the estrogen receptor.
