Spermatogenesis - sperm diagnostics
3 important questions on Spermatogenesis - sperm diagnostics
The predictive parameters of sperm for sperm diagnostics?
- motility
- volume and the concentration van the sperm
- the darkest yellowish colour -> higher concentration of spermatozoa
- morphology
How to calculated the concentration of sperm with the Burker counter chamber?
- You count the sperm cells in 100 squares of the Burker counter chamber.
- focus on sperm heads
- Count two borders of a square, it does not matter which sides you do not count
- 1 square is 1/4000 mm^3
- calculation for the concentration of sperm cells: 100 square spermcells X dulitionfactor X 4000/100 (we did this X 1000 to get from mm3 to ml)
- 159 x 200 x 4000/100 x 1000 -> 1272x10^6 million spermcells/ ml
How do you evaluate the morphology of the sperm?
For morphology you make a smear and stain the sperm cells -> Red colour enter the dead spermatozoa --> they are membrane permeable, membrane is damages.
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
