Dear tweety

The answer to this question is extremely complex and unfortunately this forum does not allow me to detail the scientific basis for the choice of this treatment. However it may suffice to say that a critical mass of sperm are required to attach to a single egg in order to induce certain biochemical changes within that egg and to allow the fertilisation by a single sperm even though thousands of sperm may have attached to the wall or the surface of the egg. Unless this critical mass is reached and the sperm binding is functional, no fertilisation will occur and therefore IVF/ICSI becomes a necessary option.

Sometimes the sperm is so bad that it cannot swim up to the egg and fertilise it.
