Question:
I have muscles in my lower region that makes it possible to move my
testicles up and down, one at a time or both together on their own 1-2
inches. Growing up I thought this was normal, but I brought it up with
a couple of friends and everyone thinks I'm crazy and no one will
believe me, even my own father. I was wondering if anyone has ever
heard of this because I can't seem to find any answers of the why and
how.

Answer:
Hey Guest, how re you doing? These are not truly undescended testes
and are called retractile testes. They do not need any treatment.
During development of the male embryo in the womb the testicles grow
and develop inside the abdomen. They move down into the scrotum
towards the end of pregnancy. In some babies this does not happen
properly and one or both testicles are not in the scrotum. Many of
these will descend after the child is born. As the child gets older
this becomes more unlikely and some treatment to bring them down is
needed. Some boys have testicles which have come down into the
scrotum but can move up and down easily. Often they are pulled back up
into the abdomen when the child is cold. For excellent patient
