As we have mentioned in previous articles, infertility is defined as the inability of a couple to conceive after 12 months of unprotected intercourse. It affects more than 5 million couples in the US alone and many times more in the world. Due to unfamiliarity with treatments, only 10% seek help from a professional specialist. In this article we will discuss what is biochemical analysis of male infertility?
The study of the chemicals and vital processes that take place in male testicles, such as the concentration of white blood cells, the level of fructose in the semen and the volume, pH and fluidity time of the ejaculate.
The semen sample of the semen is taken by masturbation in the laboratory of the clinic, the semen is sent for analysis for chemicals and vital processes as stated in the definition.
This test is a semen analysis that is typical for:
The required semen sample for this test is not less than 2.0 ml or more
It measures sperm count per milliliter (ml) of ejaculate
pH is a measure of the acidity or basicity of a solution (PH of 07 is considered neutral). In this test, it is required in the range of 7.2-8.0 to be considered normal.
3. Sperm Concentration
It measures the number of sperm cells per milliliter of ejaculate, a normal sperm concentration requires 20,000,000 per ml or more.
Motility is a measure of sperm for movement, normal sperm motility is 50% or more with forward progression. It can be classified into 4 grade:
a) Sperm with progressive motility:
These are the strongest and swim fast in a straight line
b) Non-linear motility: These also move forward, but tend to travel in a curved or crooked motion.
c) Non-progressive motility:
Sperm do not move forward despite the fact that they move their tails.
Can’t move at all.
5. Fast forward progressive motility
Sample sperm must have at least 25% or more of this type of sperm to be considered normal.
It is the study of the normal and abnormal shape of the sperm. It is considered normal if so
a) 30% or more normal forms (WHO criteria)
b) 11% or more normal forms (Tygerberg strict criteria developed by Dr. Roelof Menkveld, Tygerberg Hospital, South Africa, and disseminated by Dr. Thinus Kruger)
The sample must contain at least 75% live sperm in a semen sample
8. White Blood Cells
The sample should contain a white blood cell count of less than 1,000,000 per ml. Otherwise, it may be an indication of immunity causes of infertility and require more testicles.
Sometimes the semen sample may also be tested for bladder function, citrate or acid phosphatase for the prostate gland, and free carnitine as an index of epididymal function, at the request of your fertilization specialist.
