DNA extraction from used condom for male DNA.

The wife found the used condom in the trash.  The husband said it was his child's or someone else.  The DNA extraction proved that it was his semen/sperm in the condom.  A YPLEX extraction would not have resolved this situation because a son was involved.  It is important that we understand the specifics of your case to make sure the proper test is run.
