Look closely: this is history in the making. These are the clearest pictures ever taken of what is the starting point of every human life: ovulation occurring inside a woman's body.

"The release of the oocyte from the ovary is a crucial event in human reproduction," says Jacques Donnez at the Catholic University of Louvain (UCL) in Brussels, Belgium. "These pictures are clearly important to better understand the mechanism."

Observing ovulation in humans is extremely rare, and previous images have been fuzzy. Donnez captured the event by accident while preparing to carry out a partial hysterectomy on a 45-year-old woman. The release of an egg was considered a sudden, explosive event, but his pictures, to be published in Fertility and Sterility, show it taking place over a period of at least 15 minutes.

Shortly before the egg is released, enzymes break down the tissue in the mature follicle, a fluid-filled sac on the surface of the ovary that contains the egg. This prompts the formation of a reddish protrusion, and after a while a hole appears, from which the egg emerges, surrounded by support cells. It then enters a Fallopian tube, which carries it to the uterus.

Gross but very cool ;)

If you ever wondered where you REALLY came from ;)

1. yuck. how long does the egg stay alive before menstruation comes up? n/t

[bicentennial_baby]

The egg is viable for 24-48 hours, iirc

[REP]

28. Well, it takes about 5 days to get from the ovary/fallopian tube to uterus

Once it's in the uterus, I believe it's viable for 48 hours, but it's 'alive' for about a week.

[LeftyMom]

39. No, that's not correct.

The egg dies after a day or so. Sperm meet the egg in the fallopian tube, and that's where conception occurs, if it does. The fertilized egg then works it's way down to the uterus and implants, or the unfertilized egg, now dead for some time, is sloughed off with the uterine lining.

[LeftyMom]

38. The egg dies in a day or two, it takes another two weeks or so until ovulation.

2. Can we get some chika-chicka-wow-wow music in the background for that pic?

  I mean, after all these years, we're finally seeing the other explosive gamete release...

:evilgrin:

PB

[Hekate]

23. Yeah, I want the music! nt

[Book Lover]

3. Hardly gross

Then again, I own a set of these; maybe that colors my perspective :-)

This is great! I hope we can put a few of these images in one of my A&P books...

[uppityperson]

41. Very cool picture!

Amazing timing to get it and a very cool picture, hardly gross, just what it is.

[Hekate]

4. Ooo, that's fascinating. Nothing gross about it to this woman.

I went in for an ultrasound to check how my innards were doing perimenopausally and the nurse-tech said, "Oh look, there's an egg follicle!" I was 52, and it actually kind of thrilled me.

I think there will be plenty of other women who feel the same way.

[PassingFair]

25. Count me in.

That is FLIPPING FASCINATING!!!

I never thought I'd see it!

[ccharles000]

5. I don't know much about how a baby is made.

I figured sense I am gay that sort of info was not important to me. If I am correct the woman lays an inner egg and sperm infects it and a baby grows.

PS.I think this proves evolution. Birds lay outer eggs and women lay inner eggs. Then again I could be having one of my stupid moments.

PS#2.If that is what the inside of a woman looks like thank god I am gay.

[REP]

8. "Infects it" is about right

Don't have to be gay to see it that way. I had myself babyproofed a couple of times.

[uppityperson]

42. I almost hate to tell you, but your guts look very similar to this.

Your insides are gooey and full of fluids and organs also. I don't think your being gay precludes you from having intestines, but then I could be wrong since I still don't get the toaster thing either.

[REP]

6. Anyone who's ever had mittelschmerz knows it takes at LEAST 15 minutes!

'Sudden, explosive event' my ass. It takes at least 15 minutes and the ovum expands to the size of softball (or so it feels).

[Indenturedebtor]

9. What's mittelschmerz? n/t

[Sal Minella]

16. Translates to "middle-pain," meaning it occurs between periods.

[Indenturedebtor]

20. Ah my wife had that the other week. I was worried about her.

So that's supposed to be caused by ovulation?

[REP]

21. See my post below

[Indenturedebtor]

26. Thanks :D I will tell her... or maybe I won't cause I want babies more than she does hahahahaha n/t

[REP]

19. Literally, "middle pain," the pain from ovulation

Some, if not most women experience sharp cramping pain from one ovary during the mid point of their cycle with the release of the ovum, hence "mittelschmerz," a German word meaning "middle pain." The pain is on one side one month, then the other the next (in general) as the ovaries 'take turns' ovulating (again, in very general terms).

[Ilsa]

45. It is possible for it to be one of the most painful events on the planet.

Seriously, an easy case of it feels like an ice pick going through the abdomen on one side. It also leaves a woman feeling very sore on that side of the abdomen for several days. I have known other women who claimed it was easier to give birth than experience ovarian cysts and mittelschmertz.

[bicentennial_baby]

7. I don't get what's gross about that...

:shrug:

[REP]

10. Surgery is mildly barfy to some

:wtf:

[bicentennial_baby]

11. Oh, I know...I thought the OP was referring to the process itself

:shrug:

[Indenturedebtor]

12. It just looks gross is all. Not throw up in your mouth a little gross

Just "I don't want to have a snack and look at that" gross.

[bicentennial_baby]

14. Gotcha

Understood

[Solly Mack]

13. Now that's neat

[Hekate]

15. Yeesh. You'd think some of the guys in this thread never had mommies who read them about how babies

...grow inside Mommy's tummy, with pictures. :eyes: Or that some of these guys just sprang fully formed from the head of Zeus without the intervention of a mommy at all. Oy. Have I got a bedtime story for them!

Hekate

[bicentennial_baby]

17. I know, right?

[Indenturedebtor]

24. Any goo covererd hemroid looking thing is kinda nasty

I think that the human body is amazing, but some of it just plain strikes me as nasty :shrug:

[Book Lover]

27. Think or know?

Yeah, the complex hormonal part of ovulation and gestation made me tune out too in school, but c'mon folks! Do a little googling, willya?

29. The joy and wonder of watching my wife give birth

which I was so prepared for and was NOT going to freaking faint, became a whole different proposition as I got to watch her C-section instead.

Some of us are not cut out to be in the health profession... doesn't mean we're insensitive male idiots.

Or maybe it does... I'm fairly comfortable with that. ;)

[Book Lover]

30. Where did I accuse anyone of being insensitive?

Ignorant, yes, but insensitive? Get out of your defensive position, friend.

[Sundoggy]

31. LOL

Read your own post, "friend".

It's clearly implied in the comment we're responding to. Or, you may interpret the Zeus's head thing any way that makes you happy.

[Deja Q]

18. And in color on NBC!

Pity they didn't include some sperm...

[Lone_Star_Dem]

22. That is so cool!

Even if it did kind of give me cramps.

[AlCzervik]

32. that's cool, thanks for posting. No yuck factor for me.

[Deja Q]

33. Talk about a break-out performance!

:wow:

Imagine that, he's come out of his shell!

:rofl:

Sorry, couldn't resist. An egg-celent joke, yes? Or is the yolk on me?

:spray:

Or am I just a dumb-cluck?

:hide:

Fascinating!

[Deja Q]

35. And, its actual size is smaller than the size of the period at the end of this sentence

.

[Bunny]

36. Just freaky, innit?

[Deja Q]

37. And given the size of the sperm, I'm amazed the little pollywogs don't fear being flattened by that!

:wow:

[uppityperson]

43. THANK YOU for pointing that out.

It's not like you would notice if you saw it happening, unless you had a microscope aimed at it, which was excellent timing here.

[undeterred]

40. This has surely been seen by surgeons before.

[Duer 157099]

44. I remember doing that!

Ahh, seems like it was just yesterday... how time flies
