What is normal progression for sperm?
Normal motility is 50% or higher. In other words, at least 50% of the sperm in an ejaculate should be live, swimming sperm. Progression is the rate and speed of forward movement. The desired progression is +2 or higher on a scale of +1 to +4.
What is progressive status of sperm?
There are two kinds of sperm motility, referring to the way the individual sperm swim. Progressive motility refers to sperm that are swimming in a mostly straight line or large circles. Non-progressive motility refers to sperm that do not travel in straight lines or that swim in very tight circles.
What is sperm progressive percentage?
Sperm concentration. 15–259 million per mL. Total motility (progressive and non-progressive) 40–81 percent. Progressive motility.
How is progressive motility calculated?
It is calculated by multiplying the volume by the concentration (million sperm/ml) by the motility (% moving). There should be more than 20 million motile sperm in the ejaculate.
What is motility progression grade?
Motility – Motility refers to the percentage of moving sperm in the raw ejaculate. Samples are considered normal if they have greater than 40% motility. Progression –Progression refers to the forward movement of sperm and is recorded as: Grade 4: Fast and forward progression where sperm move in a straight direction.
Is 55 active sperm motility good?
Sperm count: at least 20 million per milliliter (m/mL) Sperm motility, or the ability to move rapidly: 60% to 80% actively moving.
What are the who guidelines for semen analysis?
This investigation is carried out according to WHO guidelines, focusing more on the concentration, morphology and motility of the sperm(s). Semen Analysis explained according to WHO criteria: A complete semen analysis should include ejaculate volume, sperm count, concentration, motility and morphology.
What is the who criteria for normal sperm morphology?
WHO criteria: >30% normal forms ( 100 cells evaluated) b. Strict criteria (higher predictive value in determining rates of pregnancy in IVF program) are based on the morphology of postcoital spermatozoa found at the level of the internal cervical os. 100 cells evaluated for only normal sperm (>14% normal forms).
Can the patient be considered fertile based on normal semen analysis?
The patient cannot be considered fertile based only on normal semen analysis. It was shown that 30% of all patients with normal semen analysis have abnormal sperm function. Semen specimen are obtained by masturbation into a sterile wide-mouth container after 2-5 days of abstinence and analyzed within 1 hour of collection.
How many patients with normal semen analysis have abnormal sperm function?
It was shown that 30% of all patients with normal semen analysis have abnormal sperm function. Semen specimen are obtained by masturbation into a sterile wide-mouth container after 2-5 days of abstinence and analyzed within 1 hour of collection. Therefore, the patients should be strongly recommended to collect samples within clinic area.
