Benefits and disadvantages of manual sperm analysis and computer assisted sperm analysis

Method	Advantages	Disadvantages
Manual analysis	Low acquisition cost	Takes relatively long time for analysis
		Subjective Counting
		Only rough analysis
Computer Assisted Analysis	Fast analysis	High acquisition costs
	Highly reproducible with same settings	Regularly maintenances necessary
	Detailed analysis	Different settings may dramatically change results
	High statistical power due to objective analysis of numerous sperms
