Hello and welcome to HCM,
There are various parameters in
semen analysis which are important for a male to bear children.
Motility is one of them.
Motility of viable sperms is fast, forward, progressive and to-fro motion.
More than 50% sperms should have this motion.
Less than 50% sperms having this motion is abnormal and will interfere the conception.
Besides motility, other parameters are semen volume per ejaculate, sperm concentration and morphology.
Semen volume should be atleast 2 ml per ejaculate.
Sperm concentration should be atleast 20 million sperms per ml.
More than 50% sperms should have normal morphology i.e. a head, mid-piece and a tail.
Abnormal forms include double head or tail, dead sperms, abnormal shape of the head etc.
If the smeen analysis is within normal limits, other causes have to be ruled out.
Thanks and take care
