How to perform a sperm analysis under the microscope | urologist göttingen

[@OBCS80]

I’ve recently had to do two tests for fertility so this was very illuminating in explaining me what (hopefully) happens in the lab that tested my samples. Thank you.

[@bendirval3612]

Super interesting. This is fascinating as an amateur microscopist and as someone interested in this type of testing. Thanks.

[@MorleyGames1]

Such a good doctor they gave him the title twice

[@UroChannel1A]

And in this video I reveal the secret why: kzbin.info/www/bejne/Y6CZqKOJnLqSprM

You’re a great teacher

G❤❤d Spe₹m Analysis .This episode shed light on my quest as why an Microbiologist told me to keep the container of my spe₹m on Radiator before it was taken to lab in London.

[@joea.1606]

Thank you so much this helped me understand where we come from…

[@UroChannel1A]

You are so welcome!

[@janeajapawung1763]

You don't mention the stains nor the composition of the fixatives

[@jeanninecathcart627]

If a 2-tailed sperm fertilizes the egg will it result in a normal pregnancy?

[@ChrisD4335]

I just wanted to see my sperm so i bought a microscope off facebook marketplace and couldn't make out anything, it seems my mistake was just not waiting for it to declump

[@UroChannel1A]

Most probably, you didn’t buy a microscope with phase contrast. In usual bright field microscopy you won’t see much.

[@kenzobatt5718]

Does darkfield or brightfield work better?

[@Eroc.48]

What is the recommended magnification for this?

[@UroChannel1A]

Times 1,000 for morphology, for the rest times 400.

[@casparroofingchannel]

Very helpful

[@UroChannel1A]

Glad you think so!

[@tyson393]

In my casa report, I have vitality 0, but 53% motiles sperms including decebt rapid and moderate progressive..is that an error in the report?

[@Airbender24B]

How does this process vary if it is to verify the success of a vasectomy?

[@UroChannel1A]

It will be much simpler, yet also quite time-consuming. It is centrifugation of the ejaculate and thoroughly looking through 2 samples for any spermatozoa.

[@nightstormoutdoors6080]

May I ask why did you not use a cover glass on the slide before viewing it under the scope? Also, could you tell me which stains you used, and would Meth Blue be a good stain to use to check for white blood cells (Leukocytes) in the semen?

[@UroChannel1A]

I always use cover slips. The only exception is for morphology where I use oil. The stains are described in the WHO lab handbook. Methylene blue is not standard procedure.

[@animeshrose]

I know this is stupid. But is there any way to collect sperms from water. Like if semen is mixed with water can a viable sperm be extracted out for fertilization (say)?

[@UroChannel1A]

If you mix sperm with water, the survival time of spermatids will be very limited.

[@muhammadhamzashakeel6014]

why results of different labs varies....how much variation can be seen. If we got tested by two lab in same months...how much percentage variation can be come into see.....

[@UroChannel1A]

Different people examine samples from different dates with different methods using different equipment. I think, this opens a window into the various possibilities of differing results.

[@Macatho]

Great video. But is this stuff not automated nowadays?

[@UroChannel1A]

Thank you! Automated solutions are on the way but so far it is very difficult to produce reliable results with automation.

[@Thunderguitars]

Hi, thanks for this vieo. A question, do you need phase contrast to visualize fresh sperm? Thanks ;)

[@UroChannel1A]

Yes, absolutely. Without phase contrast , the view is very restricted.

[@rosalen77]

As per WHO 2010 you should not use vortex and only mix specimen by strile pipette, may I know what kind vortex are you using? Won't it effect the sperms?

[@UroChannel1A]

I am afraid, that's not true. Thorough mixing is very important to distribute the spermatozoa evenly within the ejaculate in order to avoid incorrect results. A vortex mixer is allowed, in Germany for our regular national proficiency tests it is explicitly recommended. The WHO laboratory manual, 5th edition, 2010 does not ban these devices. It only cautions not to overdo it: "Do not mix with a vortex mixer at high speed as this will damage spermatozoa." (p.18)

[@waldrobfarms3946]

What was the magnifications used

[@UroChannel1A]

400 + 1000

[@janiceellaine]

What are possible factors that affect microscopic examination of sperm?

[@UroChannel1A]

Sample issues. Either not all of the ejaculate has been collected or problems in the workflow. Sperm needs a warm place otherwise it will affect sperm motility. It is important to commit to sperm analysis. I always make time for this at the end of the day. There is a certain time slot for doing the analysis. Storing the sample away all day is no option.

[@mikenealon4042]

what is the shelf life of sperm?

[@UroChannel1A]

If you put them on a table, just a few minutes.

[@uzoechisamuel]

Is this a volume of semen from a single ejeculation?

[@UroChannel1A]

Yes!

[@dpmercado5400]

Doctor, I had orchitis 30 years ago and developed azospermia. I caught mumps in my late 20's. From then on my sexual appetite has not gone down; so I suppose it has not affected my testoseterone levels, right? Now in my 50's, my libido is still very high, moreso as I lift weights quite regularly. My testosterone is okay despite azospermia right?

[@pinkpanther0001]

Bin beeindruckt. Wusste nicht dass urologen auch solche Tätigkeiten machen. Hut ab

[@UroChannel1A]

Vielen Dank! Aber das ist Kerngeschäft. Urologischer geht kaum. Frohe Weihnachten!

[@Ali-tb2py]

So interesting!

[@princefk9923]

Nice bro❤

[@UroChannel1A]

Thank you!

[@shivamdwivedi4067]

fixation liquid ?

[@UroChannel1A]

What for?

[@Kaldoon73]

i think that the video will be better without music

[@wayneenterpriseslimitedukw3130]

I’m really concerned and worried as me and my partner are trying for a baby for the past 10 months no such look yet , but we both have had a megaton of stress ?

[@keithvoller4424]

Very helpful. Could do without the background music though

[@therealmarv619]

I wish you showed different real colors of Semen, and the type of semen which has "jelly-like globules" and the normal size of these globules..

[@guhitph]

Ah, this is how its done... Nice

[@LongThanhYoutube]

Doctor with a harzard tag on the blouse ???

[@UroChannel1A]

Believe it or not: the authorities demand it! Germany has indeed some crazy bureaucratic regulations…
