The theme of this dissection was reproduction. Dr von Hagens revealed the organs that carry a sperm from its origin in the testis, through many metres of convoluted tubing and into the female genital tract. The dissection, especially of the male genital tract, is challenging because many of the tubes are small and hidden within the bony walls of the pelvis. The dissection involved cutting through the bones of the pelvis in just the right place to keep the relevant organs in tact.
