What is a good sperm motility score?

A total motile sperm count over 20 million is considered to be normal. Lower than 5 million is poor sperm motility. Less than 1 million is severe poor sperm motility.

What does sperm motility index mean?

Results: Sperm motility index values demonstrated statistically significant correlation with motile cell concentration, total cell concentration, and percent motile cells. They were also shown to reliably represent semen quality assessment obtained by two experienced andrologists.

What is a good motility score?

32 per cent
Motility. Your motility score within a sperm analysis is the percentage of sperm that are moving. Many stand around, idle. But if more than 50 per cent are moving, that’s a great result. Anything over 32 per cent is fine.

Is 51% sperm motility good?

Normal sperm count is more than 20 million per milliliter. Counts of less than 20 million per milliliter are considered low. This describes the percentage of sperm that are moving. 50% or more of the sperm should be moving in a normal forward movement.

What is motility grade?

Motility speed is classified as rapid progressive, slow progressive, non-progressive or non-motility. A grade of 4 indicates rapid progressive movement. Normal sperm have >50% motility and a grade of 3 or 4. Sperm motility is as important as number.

What is normal motility rate?

Semen analysis results table

Is 35 sperm motility good?

Progressively motile sperm generally move at 25 micrometres per second or more and at least 32% of the sperm in a sample must be progressively motile for the overall sperm motility to be deemed “normal”.

What is the normal active motility?

Sperm count: at least 20 million per milliliter (m/mL) Sperm motility, or the ability to move rapidly: 60% to 80% actively moving. Sperm morphology, or the sperm’s shape and size: 70% to 90% normally shaped.

What is low motility?

Low sperm motility refers to the inability of the sperm move quickly and efficiently toward their desired destination, the egg. Among men with low sperm motility, the majority of the sperm are too slow and haphazard in their motion to make it to the egg; in fact, most probably do not make it past the vaginal canal.

How do you read sperm motility results?

Sperm movement, or motility, is important to fertility because sperm must travel to fertilize an egg. An automated system analyzes the sperm for movement and rates them on a scale of 0 to 4. A score of 0 means the sperm are not moving, and a score of 3 or 4 represents good movement.

How is the sperm motility index related to semen?

Sperm motility index is a measurement of optical density fluctuations caused by motile cells; therefore, a positive correlation was anticipated between its values and semen motility parameters.

How is concentration of progressively motile spermatozoa calculated?

The derived variable `concentration of progressively motile spermatozoa’ (CPMS) was calculated by multiplying the sperm concentration by the sum of motility grades a and b (progressive motility) expressed as percentages.

What are the results of the sperm quality analyzer?

Sperm parameters including sperm motility, sperm concentration, and sperm motility index assessed by the Sperm Quality Analyzer were evaluated. Results:Five hundred seventy-six metaphase II oocytes retrieved were manipulated. The normal fertilization (2 PN) rate per oocyte was 64.9± 26.0% (mean± SD).

How long does it take for sperm motility to decrease?

Sperm motility decreases the longer it is outside your body, so be sure the sample is analyzed within 1-2 hours of collection. In the “standard” method, a technician uses a regular microscope slide to count about 100 cells [1].
