Detecting STR profiles from degrading menstrual blood samples and their use as possible evidence in forensic investigations.This research explores DNA consistency and attempts to detect STR profiles from the degrading menstrual blood samples (MBS) as reliable forensic evidence.  Peripheral (PBS) and MBS of 30 healthy fertile females were taken on the menstrual cycle's second day.  Moreover, complete STR profiles (24/24) for DNA were discovered in all the intervals (0, 2, and 48 h).  Periods of 0-8 h demonstrated the maximum extents of DNA materials.  Full STR were discovered in all the intervals (0, 2, and 48 h).
