preview of the answer..
Semen is mostly a common finding when sexual assault investigations are being conducted. There are various methods, which are used concerning semen, and they include the location of semen using the fluorescence techniques and macroscopic examination. Other methods include semen detection with microscopic examination, semen detection with acid phosphatase test, and the FISH technique. According to me, semen detection with the microscopic examination is the best method since it confirms sexual intercourse. This method is also acceptable to both the judicial authorities as well as he medical teams (Savino, Turvey & Freeman, 2011) …
