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.
Semen supplied by a sperm bank prepared for ICI or IUI use is also suitable for ICI. A retrospective cohort study showed that total motility and total motile count (TMC) after thawing were associated with ongoing pregnancy rate; with best ICI results at total motility of ≥20% and a total motile count (TMC) of ≥8 × 106 after thawing.

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.
Sperm motility is dependent on several metabolic pathways and regulatory mechanisms. The axonemal bend movement is based on the active sliding of axonemal doublet microtubules by the molecular motor dynein, which is divided into an outer and an inner arm. Outer and inner arm plays different roles in the production and regulation of flagellar motility: the outer arm increase the bea
The practise of tucking can reduce both the sperm count and sperm quality. [41] Meta-analysis indicates that mobile phone exposure affects sperm quality negatively. [42] Regarding diet, malnutrition or an unhealthy diet can lead to e.g. Zinc deficiency, lowering sperm quality. Sperm quality is better in the afternoon than in the morning. [43]
c is the concentration of motile sperm in a sample after freezing and thawing, approximately 5–20 million per ml but varies substantially; r s is the pregnancy rate per cycle, between 10% and 35% [39] n r is the total motile sperm count recommended for vaginal insemination (VI) or intra-cervical insemination (ICI), approximately 20 million pr ...
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.
