Apart from these changes, the initial evaluation and handling methods remain in most instances the same as in the fourth edition of the manual, 5 i. The following categories of defects are important: Evidence suggests that sperm defects are the major contributors to complete failure of fertilization in IVF. The decision to reject categorizing progressive spermatozoa into fast and slow in the WHO manual was also based on the inability of technicians to gauge velocities accurately and the manual suggests that if velocities need to be known, a computer assisted sperm analyser system should be employed.
