As Boys Grow (1957)

foreign hi I'm Gene Douglas and that's part of my freshman track team the boys are really working very hard say maybe you'd like to meet some of them well there's Bill he's going out for the high jump and Jim the broad jump and Sprints too Mike is number one boy at the shot put right now he's a pretty good distance Runner too but Ben's clock the best time for the 440 so far pole vault is George's specialty but he's giving the high jump a good try too and Pete well he's trying most everything right now they make a pretty fair team anyway they're sure trying hard enough hey coach yeah I twisted my ankle oh is it bad I don't think so well see me inside will you okay okay that's it for today everybody inside come on here let's take a look how'd you do it I was taking a jump and I landed side with him yeah I can see well I'll put an elastic bandage around it I'll take a look at it and see how it is tomorrow okay why does the toys have to happen to me you guys never get hurt oh you're just having a little bad luck yeah but why me well he's built a little different from you Pete he's developed earlier yeah but why he's not any older than I am it's not just how old you are kids develop a different time hey coach is Mickey Mouse here gonna live Mickey Mouse all right take it easy you better get your clothes on okay that might she's sure filling out and it won't be long before Pete starts putting on some weight too in fact all these kids are starting to develop now they're all around 14 15 years old and there will be a lot of changes taking place thanks to do your homework what homework you know your math oh that sure I couldn't get the last one oh great that's the one I was wondering about today what happened to your face oh this cut myself shaving yeah maybe I'll start shaving soon come on we better get a move on or we'll be late for Club yes shaving is part of it and there were still other changes some of these things most kids knew about While others didn't hey you know something no what I had a wet dream last night what dream what's that oh you know the sperm comes out of your penis sperm yeah thought of a sticky stuff guys part of a baby didn't your brother ever tell you about that no no he never says much about anything so that means you can start a baby it was something new to bill this business of nocturnal emissions just as a lot of other things were new growing up is a time of change everything seems to happen at once the coach that is glands well you get those from your parents hey what is this you're all taking the afternoon off hey coach didn't you say it was glands that made guys different yeah that's right well today in Biology class Mr Davis said we're all different because of our parents that's right I meant the way your body develops at puberty puberty that well that'll take a little explaining maybe later huh yeah but when well how about after practice this afternoon sure great okay but we've got work to do now come on let's get out there come on fellas so that afternoon in the locker room I started answering some of the boys questions no just talking see it on if you want to let's see where was I oh yes well each of us is different from the day we're bored no two people are exactly alike some of those differences are inherited from our parents see then at puberty puberty glands begin to work and our bodies begin to change and what's puberty well puberty well puberty is a lot of things mainly though it's a time of change for you it means your bodies are changing from Boys to Men you mean like having the shave say when's the guys start achieving anyway oh there isn't any special age you're all going to start at different times that's because everybody matures according to his own body's rules in general everybody grows broader in the shoulders the ribs and the pelvis your arm and leg bones grow longer and so does your back from the neck to the buttocks but everybody doesn't develop at the same time or in the same way Jim for instance is bigger all over than you Pete but that just means he started filling out earlier you'll catch up George now is growing tall instead of filling out Mike is more like Jim Ben will be tall probably and big all over well everybody is just naturally a little different yeah but where do these glands come in well it's the sex glands or testes that actually get these changes going here maybe a diagram will help here's the penis and the scrotum that holds the testicles or testes inside now when you're around 14 maybe sooner maybe later the testes start making a chemical substance called a hormone it's this hormone that causes the changes it enlarges the penis itself and starts hair growing here and under your arms and on your face it even affects your voice makes it deeper it also makes it grow thicker or taller or both that hormone is that what you call sperm no sperm is something else sperm is made in the testes too you all know what sperm is yeah it's a guy's part of a baby isn't it that's right but how does it get out from the testicles through tubes here there's one from each testicle goes up down again through a storage place and out into the penis now when the penis erects gets hard the sperm can come out in what's called an ejaculation not every time though uh what do you mean well I mean sometimes the penis gets hard without well oh without an ejaculation of sperm oh yes that's right you see all an erection is there's an increase in blood in the penis which is made up mostly a spongy now when something excites us sexually this tissue fills up with blood and the whole organ is extended or hard erect sometimes that just happens by itself doesn't it you know like in the morning oh yes you don't have to be thinking about sex to have an erection pressure from a full bladder can cause it there rhythmic movements of the body uh horseback riding say yes George does an erection well does that mean you have too much sperm and you ought to get rid of it get rid of it no but sometimes your body will do that by itself it's nice it's called the nocturnal emission or wet dream then you can cause an ejaculation by yourself too by masturbating rubbing the penis sometimes you hear that masturbation affects your mind or your manhood it isn't true for kids your age it's just something normal does that well I was told I had something to do with pimples and stuff is that right no no you see when you reach puberty and all these changes start taking place there are a lot of glands involved not just the sex glands for instance there's one in the back of the brain called the pituitary and then there's the thyroid glands here in the neck now some things about these glands are still a mystery but we do know that a hormone from one can affect the others and in a lot of people your age this may partly cause skin trouble well what can you do about it oh if it really bothers you you should see a doctor he'll tell you what to do it can be cleared up pretty well these days hey it's about time hey could we go on with this tomorrow yeah how about it sure okay come on down early huh oh yes there were still plenty of questions and as usual some guys thought they knew all the answers and so that though pushes her into the water boy did she get mad maybe she was having a period or something oh that doesn't make any difference my sister goes something when she's having her period period what's that yeah no menstrual periods don't you know what that is no say somebody ought to give you guys the word okay wise guy what is it hey what's going on here well these goofballs have never heard of a menstrual period now is trying to tell him and he didn't know what he was talking about either yeah okay simmer down have a seat I brought some charts maybe this will help the female reproductive system and fertilization hey look polywise now wait a minute these are sperm cells but let's start from the beginning menstruation is just one part of a whole series of things that take place in the female sex system it's arranged something like this the vagina that opens out between the legs the uterus or womb a pair of tubes and two sex glands or ovaries now about once every month these glands produce an egg cell or ovum which passes along one of these tubes to the uterus an egg you mean like a chicken egg no not exactly it's very small you'd need a microscope to get a really good look at it it's like a chicken egg in one way though if it's fertilized by a male sperm cell it'll grow into a baby here in the uterus first the uterus grows a lining which would take and feed the egg if it were fertilized but when it's not fertilized it disintegrates and if in the lining and some blood pass out through the vagina and this is called menstruation yes Pete when does the girl start having these periods when she reaches puberty around 13. that means she can have a baby then yes that's right just like you can become Fathers as soon as your testes start making sperm here this is what happens when the egg is fertilized the sperm meets the egg in this tube then the fertilized egg becomes attached to the uterus wall and the cells multiply and grow into a baby yeah but how does it get there you know not just the sperm and egg stuff I mean well what really happens oh what you want to know about is sexual intercourse well that happens like this here here's a cross section of the vagina the erect penis enters here and rhythmic movements a pumping back and forth causes an ejaculation from the penis some of the sperms swim up here through the uterus and on into the tube where they may or may not meet an egg cell if one does then the egg is fertilized and settles down here in the uterus and grows into a baby about nine months later the baby is born through the vagina this is how we all came into the world yeah but babies know that that's not all you got with girls for is it no you're right going out with girls is fun when you get older you probably want to get married and start a family say when should a guy start going around with girls Oh there's uh there's no real answer to that whenever you feel like it I guess maybe the first time you'll want to ask someone to a party or a dance maybe you'll need a partner but there's no special age just like there isn't any special reason for taking a girl out most guys just like female company well that's it for today fellas let's get out to practice huh [Music] the fellas were pretty busy all spring working out for the team and with their schoolwork but they had time for other things too hey how would you and Barbara like to go swimming tomorrow we'd love to [Music] well we all bring something to eat we could stay all good okay I'll make something hey great how about a big old chocolate cake oh I don't know we can try well anyway we'll start about nine okay [Music] thank you foreign
