what is pubic-disfuction disorder and....?!

Oh, what an interesting question! You will find only information about women and childbirth if you look up "pubic dysfunction", because that is when you see the most of it.

The term refers to the bit of cartilage (symphisis pubis) that joins the two sides of the pubic bones of the pelvis. It's a good thing you don't have bone right across, as you need extra room for childbirth. Lovely picture and description here:

Males have one also, but since they are not going to experience childbirth, there isn't as much stretch in it. They can do it a bit of damage during exercise, though.

Injury

The pubic symphysis widens slightly whenever your legs are stretched far apart. In sports where these movements are often performed, the risk of a pubic symphysis blockage is high, in which case, after completion of the movement, the bones at the symphysis do not re-align correctly and can get jammed in a dislocated position. The resulting pain can be quite severe, especially on further strain put upon the affected joint. In most cases, the joint can only be successfully reduced into its normal position by a trained medical professional.
