Semen
The American photographer Andres Serrano sometimes takes photographs of body fluids and displays them as artworks. One example is Blood and Semen II (1990), which is a picture of blood and semen mixed together. Some people are shocked by such pictures and think it is wrong of him to make them, while others think that as an artist he is free to create such works. Another of Serrano's pictures, Blood and Semen III, was featured on the cover of the 1996 music album Load by the American heavy metal band Metallica.
