Count means you have 2 million per mililiter as a total. I believe in a healthy ejaculate is around 100-200 million per mililiter. My husband has 60 million per ml total and then after the "sperm wash" has 12 million. Anything above 20 million is still considered normal. So you are on the lower end of the spectrum. Motility means how the sperm are moving and swimming once inside the vagina.
I am assuming since it says nil and immotility is 100% that your sperm are not moving. Morphology is the shape of the sperm. Healthy sperm have a spear-like head to burrow into the egg and a tail. Some abnormal sperm can have two tails, two heads, etc. And the sperm volume, now I am guessing here is the amount of fluid carried with the sperm.
For a better interpretation of this, you would need to consult your doctor and have them explain which criteria they followed. Some clinics use the Kruger test or the one regulated by WHO. Maybe to help improve you can take multivitmans such as the GNC Mega Man vitamin. It has all of the natural nutrients to help improve count and motility. You can also take additional vitamins such as a B-Complex vitamin to help jump start your hormones.
You can also have the doctor run a hormone or blood work up to make sure your hormones are all normal. And if there is a nutrient deficeiency, it can usually be correct with taking a really good vitamin or prescribed medication. Good luck.
