In the book "Foreign Sperm" by Donald Tyler, some interesting questions are raised regarding the potential of sperm. The heart of Tyler's theory is that foreign sperm, any sperm into a woman, and another male's sperm into a man, cause diseases.

If Tyler is correct on any point, the absence of ejaculation during karezza may be a huge benefit to long term health.
