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.
Necrospermia is usually confused with asthenozoospermia, which is the inability of the sperm to move even when alive. To check for necrospermia, samples with a high percentage of immobile sperm are stained to check for vitality. If they are dead sperm they will be stained, as the membrane is broken and the dye enters indiscriminately.
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). This is the most common type of fertility testing.
With vasectomy reversal surgery, there are two typical measures of success: patency rate, or return of some moving sperm to the ejaculate after vasectomy reversal, and pregnancy rates. In one study [3] 95% of men with a vasovasostomy were found to have motile sperm in the ejaculate within 1 year after vasectomy reversal. Almost 80% of these men ...
Asthenozoospermia (or asthenospermia) is the medical term for reduced sperm motility.Complete asthenozoospermia, that is, 100% immotile spermatozoa in the ejaculate, is reported at a frequency of 1 of 5000 men. [1]

When performing cryopreservation of semen, it is the sperm quality after reviving the sample that is of importance, because many sperm cells die in the process. To be of use in assisted reproductive technology, the sample should after thawing have more than 5 million motile sperm cells per ml with a good grade of mobility. If the grade of ...
The research is mixed on whether cycling affects male fertility, including sperm—but doctors offer some tips on protecting your swimmers, if you have concerns.
