- 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
The fallopian tubes remind me of flowers lmao
It does resemble a flower, doesn't it? Thank you for watching and sharing!
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
This was more informative than high school sex ed.
Some of the visualizations remind me of Finding Nemo...
Wow. Absolutely amazing. 3D animation like this should be used in every health class.
Our bodies are so awesome. Not periods. Whats going on inside is awesome.
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.
Amazing.. we are amongst the lucky ovum tht got fertilized.. since ovum lives for 12 -24 hours only
So my Fallopian tubes move? That's metal as fuck
@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.
This is so beautiful, i fvcking love it. Nature is so great..women are so great.
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."
Okay my ovaries hurt now!!!
I really loved the animation on the "O" in the title sequence. One of the best examples of design I have seen!
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.
This work is absolutely gorgeous!! What amazing realism this 3D medical animation has. It seems like there's a camera shooting real footage!
We all were in that beautiful when we were egg cell
I have an exam today and I totally needed to see this!! Thanks
If only ovulation accured once every ten years
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.
Its amazing how many things happen inside our bodies without us even realizing it!
@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.
Beautifully animation, and very detailed too. I learned more from this video than I did in high-school.
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.
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.
I came here by mistyping , Convolution into ovulation.
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!
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!
we are fearfully and wonderfully made by our creator
@BBCSHEEPNEWS Excellent news! Best of luck, and hope your family is healthy and happy!
WOW, what a great video.
Excellent Graphics,
Excellent Sound Effects,
Excellent narrating,
& Bulls-Eye Accurate Information.
Great explanation! :)
Glory be to God :) It's so beautiful.
Conception and life is also beautiful. God is the great creator of man. Amen
amazingly coordinated, beautiful creation!
this one of the best videos .. you are making it like a disney movie hhh
whenever i feel i cant understand this anyway..i come to this channel......grt work
I dunno but this speaker has a better voice than the other one.
wow, i couldnt have explained it better myself! this video is completely AMAZING!
Incredible really brought what I was studying to life
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.
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!!
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.
best realistic 3d. must have taken hard work to prepare. Goodluck nucleus. your videos are really amazing.
This is absolutely brilliant!
Thank you, very informative. Great video.
1:31 = coolest part!
Amazing mind blowing design at work.
Amazing animation!
okay, this is so useful as i'm learning reproduction chapter at school:)
that's an amazing and informative video. thank you.
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 :)
Fantastic 3D animation work- so realistic- B
Such Informative video and amazing graphics :) thanks for sharing
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........
great animation video than to understand from pictures, thanks
awesome photography
I'm speak spanish, but, it's so amazing! I not need speak english to understand! Thanks!
wow!!!! GOD is truly amazing!!!!!!! How delicate and how thoughtful is everything he created!!!!
@BBCSHEEPNEWS How is your wife's pregnancy going?
very informative..short but did hit the important points of the topic. :)
This is beautiful. I forgot how much I love biology. :)
good 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.
This is so GREAT & Good is so good.
wow thank you so much for this video...very helpful! *grateful bio student*
All of this is such a beautiful process
THAT WAS AMAZING!!!!!!!
thank you very helpful video
Amazing!
wow, thats so damn amazing...love it!
Thanks.. Right on target.
wow. that's amazing! thank you
wow..such an amazing video..
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
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!
very infromative. thx
wow hermoso en realidad keep loading it pls ... thanks for that beautiful video
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 :)
AMAZING!
very helpful got a test tommorow
Oookay! Curiosity will never get the better of me.
amazing what we know now. It was how all of us began our journey to where we are today - watching TH-cam lol.
great video, thanks! :)
So...fascinating
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
SubhanALLAH THATS ALL I CAN SAY ALL PRAISE TO GOD!
nive very video...... vivid colours... thank u
NO WONDER IT HURTS THEN
Explains it all
Ugh I looooove this channel they have some amazing videos.
Nice video
Wow. I just got creeped out by my own body parts. 0.o VERY detailed and thorough. Thanks for the upload!
beautiful graphics nice video
I am subscribing RIGHT NOW !!!
excellent.beautiful,amazing...........
@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.
