- UPDATE: There is an updated version of this animation! Check it out here: • Ovulation
Ovulation is the part of the menstrual cycle where the ovary releases an egg to be fertilized during conception, or sloughed off during a woman's period. This 3D medical animation depicts in exquisite detail: follicle development within the ovary, the movement of the fimbriae over the ovulation site before ovulation, the bursting of the egg from the ovary in a rush of fluid, delicate quality of the ciliated fimbriae and its movement to pick up the egg after ovulation, peristalsis of the fallopian tube to move the egg toward the uterus. Ovulation must take place in order for a woman to get pregnant, preceding the meeting of the male sperm during fertilization.

Transcript:
Ovulation is a part of the menstrual cycle when the ovary releases a ripe egg, or ovum.
Inside the ovary are hundreds of thousands of follicles. Each follicle is a hollow ball of cells with an immature egg in the center.
The typical 28-day menstrual cycle begins on the first day of menstrual bleeding.
During the first 7 days of the cycle, a few follicles begin to grow at the same time.
These maturing follicles secrete estrogen hormone into the blood stream to prepare the lining of the uterus for pregnancy.
Around Day 7, all of the follicles stop growing and begin to degenerate except for one.
This dominant follicle continues to grow and nourishes the developing egg inside it.
Around Day 12, the follicle secretes a large amount of estrogen into the blood stream.
When the estrogen reaches the hypothalamus and the pituitary gland in the brain, the anterior or front part of the pituitary gland releases a huge surge of luteinizing hormone into the blood stream.
Around day 14, luteinizing hormone causes the follicle to undergo a sudden growth spurt.
Right before ovulation, the egg detaches from the inside of the follicle.
The bulging follicle releases chemicals, causing one of the two fallopian tubes to move in closer and surround the follicle.
The follicle swells until... it bursts open, ejecting the egg and fluid from the follicle into the abdominal cavity.
In response, the fimbriae, tiny projections at the end of the fallopian tube, sweep across the ovulation site and pick up the egg.
Microscopic cilia on the fimbriae's surface transport the egg to the entrance of the fallopian tube.
Inside the walls of the fallopian tube, muscular contractions gently push the egg toward the uterus.
After ovulation, the egg lives for 12-24 hours, so it must be fertilized by a sperm from the male during this time for a woman to become pregnant.
If it is not fertilized, the egg dissolves away and is shed along with the uterine lining during menstruation.
I'm going through this process as I type this. I'm in so much pain... Now I know why.
Same, it's just like "welp, now I know why I feel like death."
I thought it was just me!!
Carolina Marchese yup, i feel like a elepant is sitting on top of my uterus only. along with the discharge from the egg exploding from the follicle. Tmi i know
Kelsey C Nothing is TMI between those who own uteruses. I feel like a fucking sludge factory every. fucking. month. This month, however, it's been cranked up to a deluge! And I'm experiencing that same back pain & cramps as my menstrual cycle, which mean my cycle will be BRUTAL. Ugh. I'll never be prepared for this shit.
***** this is my first one in a whole year so its kinda bitter sweet. Kinda excited to feel like a woman again
Wow. Absolutely amazing. 3D animation like this should be used in every health class.
The fallopian tubes remind me of flowers lmao
It does resemble a flower, doesn't it? Thank you for watching and sharing!
@davinrobinson1 Thanks for your comment. Just to be clear: **fertilization** of the egg by the sperm normally happens in the fallopian tube, not the ovary. If the sperm goes to the ovary, it has gone past the egg into the abdominal cavity. What you might be thinking of is implantation, which must occur in the uterine lining and not the fallopian tube. If an egg implants in the fallopian tube, it is called an ectopic pregnancy and poses great risks for the mother and the fetus.
omg this is both horrifying and amazing
How is it horrifying?
+Yoko Yakamori I think he means it's disgusting so much stuff in the body
Yes. Some women feel the same pain when they ovulate, and there's a name for it: "mittelshmerz" (pronounced mit uhl shmairts). It's a German word meaning "middle pain."
This is simply amazing. We never stop and think about what our bodies are doing, and how they work to ensure producing new life. All the muscular contractions and the hormone going to the pituitary gland all happens inside us and we aren't even aware of it. It's true, that our bodies do take care of themselves without us even trying. It's divine.
This was more informative than high school sex ed.
Some of the visualizations remind me of Finding Nemo...
Our bodies are so awesome. Not periods. Whats going on inside is awesome.
I really loved the animation on the "O" in the title sequence. One of the best examples of design I have seen!
Amazing.. we are amongst the lucky ovum tht got fertilized.. since ovum lives for 12 -24 hours only
This is brilliant. I'm writing an exam tomorrow about the menstrual cycle and this has given me so much insight towards the theory I've studied.
@neuroxik The unfertilized eggs are released from the ovaries into the woman's abdominal cavity and are eventually broken down by specialized cells called phagocytes.
This work is absolutely gorgeous!! What amazing realism this 3D medical animation has. It seems like there's a camera shooting real footage!
So my Fallopian tubes move? That's metal as fuck
Great work! the only negative thing that the video doesn't mention the role of FSH in stimulating the follicles at first from which one follicle will be selected to complete the cycle.
I have an exam today and I totally needed to see this!! Thanks
Great question! An egg usually survives for no more than 24 hours after ovulation. So, if sexual activity (without contraception) occurs 24 hours after ovulation, it is unlikely pregnancy will occur.
HOWEVER, if sexual activity occurs 3-4 days before ovulation, it is possible for sperm to survive in the reproductive tract that entire time, and pregnancy is possible. Hope that answers your question. For more information on planning a pregnancy, ask your doctor.
Beautifully animation, and very detailed too. I learned more from this video than I did in high-school.
Hey, that times out pretty well!! And the chorus (I'm alive, I'm alive, I'm alive) works with the shot of the egg.
Well done, LC Nilsen!
@BBCSHEEPNEWS Excellent news! Best of luck, and hope your family is healthy and happy!
Okay my ovaries hurt now!!!
Thank you Nucleus Medical Media for this very well done animation which interestingly teaches ovulation movement.
love this channel, the videos explains any topic so easy I am in Nursing school and got an exam in a week this really helps! keep up the good work guys!
This is so beautiful, i fvcking love it. Nature is so great..women are so great.
It's a nice point to recognise that the ovum is albeit briefly, ejected into the body cavity. Another shared feature with some of our vertebrate cousins. Mammals such as ourselves have a specialised anatomy to give shelter to the ovum for its development.
WOW, what a great video.
Excellent Graphics,
Excellent Sound Effects,
Excellent narrating,
& Bulls-Eye Accurate Information.
If only ovulation accured once every ten years
Its amazing how many things happen inside our bodies without us even realizing it!
Great explanation! :)
Great info on ovulation. When trying to get pregnant, there is a about a 2 day period after ovulation when the egg can be fertilized in the fallopian tube.
I came here by mistyping , Convolution into ovulation.
They sell a lot of ovulation tests at dollar stores if anyone is interested. If you are monitoring your cycle for any reason, might be helpful.
1:31 = coolest part!
amazingly coordinated, beautiful creation!
We all were in that beautiful when we were egg cell
wow, i couldnt have explained it better myself! this video is completely AMAZING!
whenever i feel i cant understand this anyway..i come to this channel......grt work
subtract 17 from her average cycle length. ex: 28-17 = 11, ovulation occurs around the 14th day, but since sperm can survive for more than a day then yes there is a possibility of fertilization.
best realistic 3d. must have taken hard work to prepare. Goodluck nucleus. your videos are really amazing.
we are fearfully and wonderfully made by our creator
Great early stage 3D medical animation work guys- I can't wait to see the final finished product. You certainly bring a storyline to life- thanks again!- Fantastic images!- Brian
this is a great video..very informative..l learned alot...thank you!!
I dunno but this speaker has a better voice than the other one.
Thank you, very informative. Great video.
This is absolutely brilliant!
Incredible really brought what I was studying to life
this one of the best videos .. you are making it like a disney movie hhh
Amazing animation!
nucleus .... you made me love studying gynecology and obstetrics !! seriously ... its way easier and i even find it enjoyable to see what am i studying .... thanks for the great work .... its a bit defective in the information but i totally understand how you try to make things convenient for everyone ..... again thanks for the magnificent animations........
Amazing mind blowing design at work.
that's an amazing and informative video. thank you.
could you guys please do something for college students? I'm in bio101 & my professor is basically an idiot. I find your videos VERY informative opposed to his poor excuse for diagrams and notes. I am more than willing to email you guys the notes & material to show you what I have to deal with in this class. I don't care if you degrade the quality by a lot,or have watermarks all across.. ANYTHING will be better than these notes & it would sure help my grade. Your ch inspired me to enroll :)
Such Informative video and amazing graphics :) thanks for sharing
okay, this is so useful as i'm learning reproduction chapter at school:)
Fantastic 3D animation work- so realistic- B
good work!
Such a FABULOUS video. SO helpful! It really clarifies the process. Thank you!
it's so fascinating how the body works
Us girls each month complain and starts to talk shit and be angry about our periods but do we actually take a second to think what your body is doing?how it's working? how it's preparing for a pregnancy? or simply that you are a productive woman? dont think about it in an ugly immature gross way as i used to do or just someday you'll understand what i mean :)
Well said!
Denise 1101 thx :)
wow. that's amazing! thank you
@rcollins305 The egg "dies" on average between 12-24 hours after ovulation. Therefore there is no longer an egg there to fertilize 2 days later. Optimal timing for intercourse when trying to conceive is the day before and the day of ovulation.
Amazing!
I'm speak spanish, but, it's so amazing! I not need speak english to understand! Thanks!
@BBCSHEEPNEWS congrats =) is this your first ???
Glory be to God :) It's so beautiful.
Conception and life is also beautiful. God is the great creator of man. Amen
wow, thats so damn amazing...love it!
great animation video than to understand from pictures, thanks
wow thank you so much for this video...very helpful! *grateful bio student*
1:41 looks like it hurts when it's actually when the egg goes down the uterus that it hurts lol. Great animation! Very informative!
AMAZING!
This is so GREAT & Good is so good.
wow..such an amazing video..
THAT WAS AMAZING!!!!!!!
awesome photography
very informative..short but did hit the important points of the topic. :)
thank you very helpful video
great video, thanks! :)
@Girlyfreak8989 the egg is fertilised in the Fallopian tube, just not implanted there. After fertilisation the fertilised egg is carried to the uterus for implantation. For ectopic pregnancies the egg is implanted in the Fallopian tube or any place other than the superior part of the uterus.
wow hermoso en realidad keep loading it pls ... thanks for that beautiful video
Thanks.. Right on target.
This is beautiful. I forgot how much I love biology. :)
At this moment right now i can feel my uterus contracting and it hurts so i guess thats what cramps really feel like :/
WOW
astonishing animation
Thaaaaaaanks
very infromative. thx
may i know if this video is reliable?
All of this is such a beautiful process
Even the ova shows & changes its color to attract the sperm.....how intelligent they r??
wow its like the egg is going through a journey :D
Nice video
Wow…. Great video
This video have full information that how to detect LH level so great useful for every one who couple trying to get pregnant because I have been using Home Check Ovulation Kit for detect LH. It was Great and this video is very good for understanding LH
Thanks for video
very helpful got a test tommorow
I am subscribing RIGHT NOW !!!
You will *probably* ovulate 12-16 days before the start of your next period, though for some women that time frame is a bit shorter.
@nucleusanimation hey.. where i can get the text of this video? because i ain't good in listening.. or someone please tell me what the videos narator said
@BBCSHEEPNEWS How is your wife's pregnancy going?
So...fascinating
Amazing
amazing what we know now. It was how all of us began our journey to where we are today - watching UA-cam lol.
@BBCSHEEPNEWS GOD BLESS YOU GUYS CONGRATS!!!
beautiful graphics nice video
