Semen analysis: what is normal?

The WHO recently re-analyzed "normal" values for semen analysis. Without boring you with statistics, I think that the results can be summarized as follows:

More is better.

Let me elaborate.
10 million sperm is better than 5 million sperm and 20 million is better than 10 million. To go further, 50 million beats 30 million while 100 million beats 50 million. In other words, the probability that a couple will conceive within a year increases as sperm counts increase. Same with motility and morphology.

Do what is my job? My job as a male infertility specialist is to help you produce more and better quality sperm.
