The normal sperm count is between 60-120 millions and your is on lower side.Also the active sperms are 13% and non motile are 42%.The low sperm count
can also be productive if the motility is high like the active sperms are more than 60% and 80% are morphologically normal sperms then even with low count there can be fertilisation and you can have a baby.The reason for low sperm count are obstruction in way;infection suffered or varicocele
which can be treated but the motility gets affected due to life style;excess of heat or working and living in hot atmosphere;habits like smoking;alcohol etc.So if you have normal erection and do not have issues related to erection then you can consult a urologist
and get examined and he will guide you with the required treatment and the sperm count will improve there should be no problem.
