Sperm anlysis:ph: 8;count: 48.9 million/ml;motility: actve 60%;morphlogy: normal 86%. Is my sperm count low? My wife is facng problem wth conceiving.

Not sure. You didn't list the volume of the semen. If the volume is one or more milliliters than your account appears to be normal. Further evaluation with your wife should be performed.
Normal. Your semen analysis appears normal, though the morphology appears a bit high for the normal values that most fertility doctors use. It is just as important that you wife is evaluated. Make sure she sees a fertility specialist or her gyn.
