    TLDR Finasteride may improve sperm count in subfertile men with low sperm count.
    The effects of finasteride on semen and hormonal parameters in subfertile men were investigated in a study of 24 men. 57% of those with severe oligospermia had an increase in sperm count after cessation of finasteride, with no decrease in sperm count observed. The study concludes that finasteride should be discontinued in subfertile men with oligospermia and used with caution in men interested in having children.
