Earlier, there were many studies related to polymorphism screening by applying computational approach to predict the functional missense mutations associated with gene like ubiquitin-specific protease 9, Y chromosome, USP9Y (41); Deleted in Azoospermia Like, DAZL (42); Superoxide Dismutase 2, SOD2 (43); Phosphatase and tensin homolog, PTEN (44).

In theory, this improved sperm count could have been due to the CC alone (since we don't have semen parameters prior to the initiation of the finasteride, the azoospermia could have been a pre-existing condition) or could have been a result of the CC therapy increasing the intratesticular androgen levels to compensate for the reduced "androgenicity" related to the finasteride use.
