What are the biggest signs of fertility in a semen analysis, out of all of the many things that are checked?

Tests that may be done during a semen analysis include:

1.Volume. This is a measure of how much semen is present in one ejaculation. 

2.Liquefaction time. Semen is a thick gel at the time of ejaculation and normally becomes liquid within 20 minutes after ejaculation. Liquefaction time is a measure of the time it takes for the semen to liquefy. 

3.Sperm count. This is a count of the number of sperm present per milliliter (mL) of semen in one ejaculation. 

4.Sperm morphology. This is a measure of the percentage of sperm that have a normal shape. 

5.Sperm motility. This is a measure of the percentage of sperm that can move forward normally. The number of sperm that show normal forward movement in a certain amount of semen can also be measured (motile density). 

6.PH. This is a measure of the acidity (low pH) or alkalinity (high pH) of the semen. 
White blood cell count. White blood cells are not normally present in semen. 

7.Fructose level. This is a measure of the amount of a sugar called fructose in the semen. The fructose provides energy for the sperm. 


All the above tests are important to determine whether
a man has a reproductive problem that is causing infertility.
Good luck
