    TLDR Finasteride daily doesn't affect sperm production or semen in young men.

The study involved 99 men who took finasteride daily for 6 months and found no significant changes in sperm count, motility, or morphology, as well as no changes in semen volume or pH. The study suggests that finasteride does not have a negative impact on male fertility. The document does not relate to hair loss or alopecia.
