The volume of the semen sample (must be more than 1.5 ml), approximate number of total sperm cells, sperm motility/forward progression, and % of sperm with normal morphology are measured. It is possible to have hyperspermia (high volume more than 6 ml) or Hypospermia (low volume less than 0.5 ml).
Total motile spermatozoa (TMS) [25] or total motile sperm count (TMSC) [26] is a combination of sperm count, motility and volume, measuring how many million sperm cells in an entire ejaculate are motile. Use of approximately 20 million sperm of motility grade c or d in ICI, and 5 million ones in IUI may be an approximate recommendation.
