Total Motile Count
Total Motile Sperm Count (TMSC)
Volume multiplied by concentration multiplied by motility: the number of actually moving sperm in the whole ejaculate. Widely used to decide between natural conception, IUI and IVF.
PED Notes
The single most practically useful number on a semen analysis, because it combines the three parameters that matter into one figure and maps directly onto treatment decisions. Rough clinical bands: above 20 million is generally reassuring for natural conception, 5 to 20 million is where IUI is typically considered, and below about 5 million tends to push toward IVF or ICSI. It falls hard on suppressive compounds and recovers as concentration and motility recover. If you track one fertility number through a recovery protocol, this is the one, since it will not flatter you the way an isolated normal-looking concentration can.
When low
What the number means in practice:
- Above 20 million moving sperm: generally reassuring for natural conception
- 5 to 20 million: the range where intrauterine insemination is usually discussed
- Below 5 million: usually points toward IVF or ICSI
These are guides used by fertility clinics, not hard cutoffs, and a single sample is not a diagnosis. Semen parameters vary substantially between samples, so an abnormal result should be repeated after about 3 months before any conclusion is drawn.
Improving it means improving its inputs: see Sperm Concentration, Total Motility and Semen Volume. Also check Sperm DNA Fragmentation, which can be poor even when this number looks acceptable.
On-cycle context: expected to be low or zero on suppressive compounds. Recovery follows concentration and motility, over months.
