Transcripts

hello everyone my name isan with mohad

rris and today I am going to be talking

about the male reproductive system so

moving into my first slide I do have the

anatomy of the male reproductive system

which I'm going to be talking about the

external and internal uh male

reproductive organs and I do have a

picture that I've also inserted here for

your reference first is we do have the

testicles so basically it's an oval

shaped organs responsible for producing

sperm and testosterone and next we have

the scrotum basically a skin muscle SE

that holds it holds the test and last

but not least we do have the penis which

is the male organ for sexual intercourse

and urination next we are looking into

the internal part of the reproductive

organ of a male so first we do have the

epidemis which is a coil tube as sperm

mature and a start and next we do have

the vast Defence so what is vast Defence

is basically a tube that carries matur

sperm from the epidemis to the Ura uh

not only that uh samal vesicles are also

present in the male reproductive organ

and those are basically glands that

produce semal fluid uh what is Amal

fluid is basically a nutrient reach

fluid that it helps nourish the sperm

and then we do have also prostate gland

which helps in production of additional

semal fluid that helps to Pro Propel

cement during ejaculation uh last but

not least we do have the cus gland uh a

gland that produce a clear lubricating

fluid that precedes uh

ejaculation so next we are going to be

focusing in the physiology of the male

reproductive

system uh first we are going to be

looking into the

spermatogenesis so basically is a

process of sperm production in the semin

furus tubules so basically to put it

other words it's how sperm are produced

so basically I have also inserted here

charts so where you can um see how sperm

are sperm cells are produced so the last

product here is called

spermatozoa so those are the sperm cells

so the steps involves mosis and then it

becomes mosis one meosis 2 and then it

goes through uh

spermiogenesis so basically the entire

regulation of this process is controlled

by hormones like FSH and

testosterone next we are going to be

looking into the hormonal regulation so

you can see how from the

hypothalamus uh it goes uh the GNR H is

generated and it goes to the anterior

pitutary and later it basically um

divides and has the own function as you

can see in this picture piure that I've

clearly put into so basically what are

hormonal regulation they helps to

stimulate the end product testosteron

and then it also has helps to support

spermatogenesis as we looked at the

slide before this next we are going to

be looking at the testosterone

production so how does um testosterone

produced they basically are produced by

the lady cells in the testes and

basically what really uh triggers the

entire production is the LH from the

patory gland and it also helps in the

male sexual development and uh increase

in muscle mass and bone

density uh next we are going to be

focusing into

ejaculation so basically what is

ejaculation so ejaculation is like uh

coordinated muscle contraction expel

cement through the Ura so as you can see

inside here there are muscles lined up

and during the contraction the semen

inside this thing will be pushed out so

that is what we do call ejaculation uh

what controls this entire process is

basically the sympathetic uh nervous

system uh which actually helps us to

regulate ejaculation so basically what

do cause what are the factors that cause

ejaculation are basically um they are

commonly influenced by psychological and

hormonal

factors next we are going to be looking

into the semal fluid production so where

does this uh fluid produced so as you

can see in this image in the semal

vesicle prostate and uh bulver retal

gland so in the three part seral fluid

are produced and basically what are the

functions that we can get from this

fluid so basically it helps in

nourishment protection and also

neutralizing the acidity of the female

reproductive tract so you know how when

if the uh female reproductive tract is

very acidic and when your sperm travels

through the tract it dies so it uh lower

the chances of pregnancy so this fluid

will help to um neutralize the acidity

in the female reproductive tract next

I'm going to be talking about the

testicul uh cancer so basically as you

can see in this picture that's uh

there's a tumor on the testes of the

male so basically this cancer is um

quite rare and the survival rates are

quite high so we don't have to worry

about that and what other way that we

can uh help us to recover from this

particular cancer is through surgery

radiotherapy and chemo theapy I will

also like to talk about the about the

male

infertility which includes uh low sperm

count abnormal sperm morphology and

impact sperm morality so this

infertility um there's many problem that

a man can face for example the ereal

problems where you can uh male organ

will not be uh erectable and very Cal

semen alteration low count of sperm in

your semen technically and low sex drive

and small testicles other CA of the male

infertility so what are the impact that

we are talking about is they have very

very significant psychological and

emotional effects on men and their

Partners which result in high number of

divorce cases nowadays

so we can conclude that male

reproductive system is something that

important to all both genders and both

genders need to take um their particular

efforts to in order to masterize the

knowledge from this particular

topic thank you for hearing out my

presentation thank you
