"Obviously, during copulation, any ripe spermatozoon can escape and cause fertilization.
During the practice of transmutation, if the procreation of another human being is desired, any mature spermatozoon can escape in order to fertilize an ovum, and that is all." (Samael).
It's confusing. So, if a couple wants to have a baby, it s enough just to "desire" it?
How can a couple control fertilization, if "any ripe spermatozoon can escape and cause" it?
