Semen analysis

Semen analyses at Reproductive Medicine Albury are carried out using standards recommended by the World Health Organisation.

 

A semen analysis measures several parameters, including:

 

i) Volume of ejaculate produced

 

ii) Count/Concentration
This is an accurate measure of the number of sperm in an ejaculate and
includes non-motile sperm.

 

iii) Motility
An accurate measure of the proportion of motile (moving) sperm is assessed. The speed at which the motile sperm are moving is included in this assessment.

 

iv) Morphology
This test assesses the number of normal sperm in both shape and size within the ejaculate. Abnormal sperm do not cause abnormal babies or miscarriage but a large proportion of abnormal sperm in a sample may lead to a decreased capacity of the sperm to fertilise an egg.

 

v) Anti-sperm Antibody Test
Antibodies may be present in either the seminal fluid or in the serum (blood). This is often a problem following vasectomy reversal. Antibodies may bind to the head or the tail of the sperm and stop the sperm from fertilising the egg. They may also cause the sperm to stick to each other (agglutinate), thus preventing them from reaching the egg.
