here we have the male reproductive organs the male reproductive organs or really a system and what's interesting about a male reproductive system that's different than a female reproductive system is with the male reproductive system we also get the urinary system or at least part of it so we could actually call this the male urogenital system euro genital system now with a female the reproductive system is totally separate from the urinary system so this term doesn't apply for females now both males and females have a primary organ of reproduction and then they have a network of tubes called accessory organs that deliver the sperm to the female reproductive tract and in the female help move the egg to meet that sperm now the primary organ of reproduction for a male is the testes the testes is the only organ you need which is particularly true these days in order to produce offspring or to reproduce it all boils down to this one single structure the testes everything else is accessory and this tubular Network also has glands called accessory glands that will dump into that main tract so really the testes is the star of the show the testes or testes their bilateral are the primary organ of reproduction in males okay and what we're gonna do is we're going to follow this tube until it leaves the body and then we're going to come back and we're gonna look at the different accessory glands that dump in to this accessory - okay so the first portion of the gross anatomy that the sperm which are produced in the testes what makes them the primary organ of reproduction but is that it produces it makes it produces the Gammons or the sexist and the gametes in a male the sucks out in a man is the only flagellated cell in human anatomy that's the sperm with it's a curzon will cap here they don't include that okay the sperm alright so the first structure the sperm enter into is what's called the epididymis the epididymis and the epididymis has a head of body and a tail and the sperm will be stored in the tail it takes them a little while to fully mature can take about 21 days after they're produced and they make their way from the head the body into the tail of the epididymis at the didymus and we have a head a body and a tail of that epididymis this is where the sperm can be stored okay now it takes about 21 days to get there but they can be stored there for several months so the things you do in your life today for the males can actually affect the sperm that you ejaculate well let's say seven eight months from now well if we have in those 21 days we're talking nine months we're talking almost a year the things you do today may affect a sperm that's ejaculated or released a year from today something to think about now when the male ejaculates or has the smooth muscle spasm this tailed the epididymis will spasm and eject the sperm through this structure in this structure is the vas deferens I'm actually going to stay consistent here the vas deferens or the ductus deferens now it turns posterior to go over the pubic symphysis what I've drawn here is a little bit of the spongy bone [Music] it's a little spongy bone add the pubic symphysis or the pubic bone I guess the first thing spongy bone we're not seeing the island cartilage covering that but that ductus deferens or vas deferens passes up over the pubic symphysis posterior lis to form this ampulla or this enlargement that's the ampulla of the vas deferens or ductus deferens so we have the vas deferens or the ductus deferens and this ends in an ambulance of the vas deferens where the ductus deferens this enlargement at the ampulla okay you can actually palpate this for the male's it will be like a hardwired now remember the testes are bilateral so there's one on each side of the body and this feels like almost like a metal cord going up over the pubic symphysis and it's going to deliver these sperm into something called the ejaculatory duct so we're going to shift to the ejaculatory duct and then Jacqueline Torre docked here is where the vas deferens or ductus deferens means the semi neveress sorry the seminal vesicle this structure this accessory gland the seminal vesicle and the duct leading out of the seminal vesicle is going to merge with that vas deferens to form the the ejaculatory duct so up next is the ejaculatory duct the Jackie Allah Torre duct now the ejaculatory duct is going to pass by this structure which is the prostate gland and it's going to meet up with the prostatic urethra for this - that's going to drain the urinary bladder so here's the urinary bladder and all back here and it drains through what's called this prostatic urethra the prosthetic urethra joins with the ejaculatory duct to form the membranous urethra and they call it the membranous urethra because we're passing through the membrane formed by the urogenital diaphragm this muscle here this is muscle they connects the pubic symphysis basically posterior to the root of the penis and the base of the rectum or anus and this urogenital diaphragm well it's kind of like a membrane that the membranous urethra passes through so the next place the sperm are going to move into is that membranous urethra I suppose it also went into the prostatic urethra prostatic urethra on its way into the membranous urethra you can see that it enters and combines with prostatic urethra in the prostate okay next we have the spongy urethra and we call it the spongy urethra because it's in what's known as the corpora spongy oh so the corpora spongy awesome it's the what's known as the spongy part of the penis and you can see that it's filled in here with all these dots and here's more of that spongy penis for the corpora body is comport spongy awesome or poorest 1g awesome this is going to be one of the erectile bodies in the mail that help hold the urethra open so that the urethra doesn't collapse because along come sperm through the spongy urethra and they're going to make their way through that spongy urethra to exit through the external urethral orifice so next up is the spongy urethra and then out through the urethral orifice orifice okay this is the pathway that the sperm will take and along that pathway it's going to pass the seminal vesicle the prostate gland the bolbo urethral gland which is actually found at the bulb of the penis this back part of the penis the bulb of the penis making its way through that ejaculatory ducts the prostatic urethra membranous urethra spongy urethra okay that's the tube now for the accessory glands we're going to talk about what they make and what they add into that tube to help support the sperm and those glands will include the seminal vesicle the prostate gland the bobo urethral gland and also some peanut lands that add to the tube but again these are all accessory structures because if you have a testes that makes gametes especially with today's technologies that's all that's required to reproduce and so we're going to elaborate on that structure of the testes quite a bit in another video
