All parameters appear to be good except for the sperm concentration of 3 million/ml. One of the reasons for this low density is due to the higher level of 7ml of ejaculate volume. If he has not abstained from ejaculation for about four days prior to testing, retesting after a few days of abstinence would improve this parameter.
Here is a link that gives latest WHO reference values for semen analysis.
As can be seen, WHO specifies a concentration level of 15 million/ml.
In any case since other parameters appear to be good, the sperm concentration should be possible to be improved with some medications. Is he known to have varicoscle or some other issues with the testicles?
Please consult your urologist for further help in this regard.
Had 7 days of break before doing the test.
