A sperm analysis involves checking a sample of semen for overall sperm health. The process can help doctors to determine the underlying cause of a person’s inability to conceive, or it may confirm the outcome of a vasectomy. A sperm analysis tests for several markers of sperm health, including:
1.The number of sperm in 1 milliliter (ml) of semen
2.The size and shape of the sperm
3.The ability of the sperm to move correctly
People may require a sperm analysis for different reasons. Some individuals or couples will request a sperm analysis if they are having difficulty conceiving. In couples that have been unable to conceive, some estimates suggest that there is a male factor present in 40 to 50 percent of cases.
