The topic of [[circumcision]] has caused a great deal of research and studies. This article lists interesting studies on various aspects.

* 1986: '''Lidocaine does not significantly reduce the adrenal cortisol response to surgery in newborns'''
:<blockquote>"Eleven male newborns were circumcised with a local dorsal penile nerve block, and 13 controls were circumcised without anesthetic. Matched pairs of pre- and postcircumcision cortisol levels in the two groups were compared. The adrenal cortisol response to surgery was not significantly reduced by the administration of lidocaine."</blockquote>

* 2004: '''Pain relief for neonatal circumcision'''
:<blockquote>"Circumcision is a painful procedure frequently performed on newborn baby boys without using pain relief. Available treatments include dorsal penile nerve block (DPNB), which involves injecting anesthetic at the base of the penis. Ring block is another form of penile block."</blockquote>
