Male reproductive system - the path of ejaculation

A run through the male reproductive tract from testis to the penis, stopping by the glands on the way.

Your videos are amazing, keep up the great work! The only way I'm going to pass this lab practical is because of you, thanks!

[@ashg3726]

samee these videos are my only hope for anatomy in exams!

[@edwardf9661]

Being a male…I appreciate your videos….they are like the “instruction booklet” for my body. If I were taking Anatomy…they would be priceless! Your voice and demeanor are most perfect for teaching…AND, the educational and entertaining aspect of your videos are A+. Thank you.

There is a mistake in 13:00 Both male and female have internal and external urethral sphincter

Looking forward to see more of your videos . Your videos are very conceptual . 👍🏻👍🏻👍🏻👍🏻

[@turuanu]

It baffles me why this video would be age-restricted, but anyway... I was listening to your description all the while picturing all that happening during ejaculation, but then I thought the whole coitus serves to build up momentum to the actual ejaculation, so does this process you described happen over time, or all at the moment of the orgasm? And what about the clear liquid known to most as precum? I would imagine that comes from the vesicles, right?

[@Mcfreddo]

No, that's from the cowper's gland. The vesicles produce the bulk of the semen.

In order for a vasectomy to be 100% effective, both ductus deferens need to be cut. My nephew had a vasectomy done and his wife still got pregnant.

[@larrycamilli9589]

I'm curious to know what percentage of urologists (surgeons) deny the existence of the internal urethral sphincter. [Some NIH papers say that it's now thought to be part of the muscle that surrounds the bladder - though it functions as an independent piece of muscle tissue.] Some videos (referring to the zone description of the innards of the prostate) just refer to "smooth muscle tissue". The cynic in me says that surgeons who almost certainly destroy sexual function (causing retrograde ejaculation) deny the existence for selfish reasons. "How could I have destroyed something that never existed?"

[@jahidolislam4117]

you problem Dubai

[@almeidahadzic5129]

rete testis is actually a net of tubules (rete meaning net in Latin) and tubuli recte are straight canals

[@noman2008]

Hi maam does the base of epididymis where the ductus deference connected..does it feel like a round tube or like circle tube feels like firm/hard and smooth.?

[@زاهية-ف8ب]

Love your way of teaching ❤️

[@manqavenkatesh4072]

Super explanation...sir..Tg.. good knowledge in life-long awareness

[@miketrissel5494]

Where do the 4 or 5 ejaculatory pulses originate? Is this a kind of sucking into a chamber and then pushing out the urethra, or is it all contained withing the tube? Is there a check valve of some kind to prevent back flow, or is part of the musculature able to tighten behind, push the sperm forward and then regroup for the next pulse? Does this squeezing come from the brain, the spine, or some other excitable muscle reaction? What are the normal amount of ejaculation pulses in the male? Do they all have the same number of pulses, or does it vary by age, health, etc.? Thanks

[@BenjaminISmith]

It's weird these anatomy models are all circumcised. As if that's natural human anatomy and not only what happens when knifes get involved

Great video. The secret of the prostate is not alkaline though it's actually sour! The ejaculat only has an alkaline pH because the Prostate only gives of 15-30%, while the alkaline secret of the other glands makes up 70-85%
