What does Casa measure?
OBJECTIVE: The CASA is able to measure multiple values for sperm motility. Included within these measurements is VAP (average path velocity), VSL (straight line velocity), VCL (curvilinear velocity), ALH (amplitude of lateral head), BCF (beat cross frequency), STR (straightness), and LIN (linearity).
How do you perform a CASA test?
The semen specimen is placed on the stage of the microscope. This microscope has a high resolution video camera attached. The video camera feeds data into the computer where it undergoes analysis by software. A computerized semen analysis will give many more parameters that are useful to the fertility specialist.

What does a sperm analysis tell you?
A semen analysis is a lab test that evaluates sperm count, motility, morphology and more. It can be a fertility test in men or confirm that a vasectomy was successful. For accurate results, follow instructions and provide a clean sample. Abnormal results often mean that more testing is necessary.
What is CASA system What are the advantages of this technique over manual microscopic method?
CASA systems are automated or semi-automated instruments which are able to identify the movement of sperm and interpret this information thanks to an algorithm [34, 35]. More precise results are hence pro-vided in a faster way compared to manual semen analysis. …
Is Hypospermia normal?
The U.S.-based National Institutes of Health defines hypospermia as a semen volume lower than 2 mL on at least two semen analyses. The presence of high levels of fructose (a sugar) is normal in the semen and originates almost entirely from the seminal vesicles.
What is the Casa test?
Research Leader. CASAS tests assess basic and academic skills in real-world contexts. Our system monitors progress in reading, math, English language, writing, and work-readiness skills. CASAS is the most widely used adult education competency-based testing system in the United States.
What is good sperm motility?
What Is a Normal Sperm Motility? A total motile count of over 20 million is considered normal. However, even if you have more than 20 million motile sperm, it may not result a higher chance of pregnancy. If you have fewer than 20 million motile sperm, your chances of having a successful pregnancy go down.
What is the normal sperm count to get pregnant?
Normal semen contains 40 million to 300 million sperm per milliliter. A low sperm count is considered to be anything between 10 and 20 million sperm per milliliter. Twenty million sperm per milliliter may be adequate for pregnancy if the sperm are healthy.
How do I read my sperm test 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 do you fix hypospermia?
Hypospermia or low semen volume may be remedied with the aid of supplements. Supplements like Prosolution pills, Semenax, and Volume Pills have been clinically proven to enhance male performance; Spermac and Vital M-40 capsules are effective herbal remedies for treating low semen production.
Does drinking water increase seminal fluid?
You can’t increase the semen volume by drinking lots of water. There is no way to increase the amount of fluid that the seminal vesicles can produce. The sperm in the seminal vesicles and prostate gland will multiply when you don’t ejaculate for a while.
