When the egg meets sperm

[sletha2067]

their like bees

[pakcheok80]

why are those eggs so colorful?

[Family00Loyalty]

howd u get sperm? lol

[mithotynochka]

@Family00Loyalty it's really easy in urchins - just shake them - and you have sperm or eggs

[akwlb2]

Well there go some babies that will never be born lol jk

[NewOrleansboii]

Nature, you scary. 

[bunnygirlo9]

how the hell did u get the eggs?

[mithotynochka]

@bunnygirlo9 it's really easy in urchins - shake them - and you get the eggs or sperm

[daBOSSofTheNAWF]

Release the kids!!...

Eggs: Enable shields!

[bizzolizzo]

wow, it seems sperm has degradatory effects upon the egg. it's like a poison.

[king4allstars]

Let me tell you something mate ... if there wasn't womans, thee google and youtube was not too!

[mithotynochka]

@king4allstars what do you mean? I am a girl by the way :-P

[king4allstars]

@mithotynochka what ??? i didnt know that ... how old are you? and i asked you a lot of things about sperm ... im getting shye

[mithotynochka]

@king4allstars haha, that's fine - I'm 25, it's natural to ask :-) But, probably you can ask your parents also?

[yungeddakid]

It's funny how the egg just sits there. While the sperm does the job.

[mithotynochka]

@yungeddakid Actually here we used special plates to stick the eggs to them. But I'm quite sure it's the sperm job mostly in the real life too :-)

[WasabiMeal]

Question.. does the egg meet the sperm or does the sperm meet the egg?

[mithotynochka]

@WasabiMeal Good question )) I think they just both meet each other. Not sure about the proper linguistics though - maybe there is a difference in terms of how do you, guys, say it here (I'm an international student)

[WasabiMeal]

@mithotynochka Yeah you're right. It's probably both but mostly the sperm flowing toward the egg.

[king4allstars]

what happens if there pass more than 1 sperm ?

[mithotynochka]

@king4allstars In that case the embryo would have extra set of chromosomes - the sperm carries one set and the egg carries one set (that's why we all have both paternal and maternal traits).

You know, there are some diseases where a person has just one extra chromosome - this is bad already (as far as I remember, only 3 types of extra chromosomes are viable, others are not). But an extra set - that's too bad.

[king4allstars]

@mithotynochka how will lookk like the child if hes born from extra set of chromosomes? he will have some genetic mutations? or what ?

[mithotynochka]

@king4allstars it's usually embryonic lethal, there will be no child. The cell is not designed to have so much genetic material - that would mean overexpression of proteins and a mess with how to divide - even the presence of one additional chromosome is handled badly (it doesn't allow you me to add a link - so just google "aneuploidy"), and the presence of the whole set of additional chromosomes is lethal.

[king4allstars]

@mithotynochka how it makes that sperm fertilize just 1 ovule? and if sperm fertilize more than 1 ovule there will be twins or 2 childs ??? i really dont understand that thing to females

[mithotynochka]

@king4allstars the sperm enters and stays inside (and releases it's genetic information) - so it can't fertilize any more eggs, it's trapped inside already fertilized one.

Not sure how the twins are born in mammals, though - I'm working with sea urchins, they have external fertilization and can have millions "children" from the same parents.

[king4allstars]

@mithotynochka but what happens if the sperms eneters in more than one ovulee?

[mithotynochka]

@king4allstars it can't be at 2 places at the same time - so it's not possible

[king4allstars]

@mithotynochka but there is not only 1 sperm ???

[mithotynochka]

@king4allstars no, there are millions! All those small dots swimming around he egg are the sperm. This is true not only for sea urchins - humans ejaculate millions of sperms too. But not all sperms are in time to fertilize an egg. Those who are late - just die.

And there is not inly one egg also. Even in humans there are many. But only that one who is fertilized first get attached and can develop, others die (but urchins can have as many fertilized ones as possible)

[king4allstars]

@mithotynochka so lets me understand .. when the first ovule is fertilizated by 1 sperm ... the other ovules are arming at the same moment and there will be only 1 fertilized ovule? have ever happened that to sperms have fertilized 2 ovules in the same time? what happened?

[mithotynochka]

@king4allstars I am not sure about humans - I work with urchins and they can have as many fertilized ones as they want. But in humans the egg should be not only fertilized, but attached to the side of the fallopian tube. And usually only one attachment occurs - that's why it's usually 1 child at a time - but exceptions exist. But I am not an expert in human fertilization :-)

Sperm can not fertilize 2 eggs at a time - when it enters - it's releasing all its contents and can't go anyehrer else

[king4allstars]

@mithotynochka so is true what i said? .... i asked you because i see in the video there are more ovules than 1 ... and i dont know how does sperm fertilize only one and what stops the remaining sperm to fertilize the other ovules

[mithotynochka]

@king4allstars there are millions of sperms - it doesn't need to be only one who does the job, that's why there can be more then 1 fertilized egg

[king4allstars]

@mithotynochka to humans? if you say that there can be more than 1 fertilized egg that means a woman will bring to life more babyes at the same time? i have a key ask wich will make me understand all this story .... what does stop the (human) sperms to fertilize more than one ovule???

[king4allstars]

@mithotynochka google is better always! i see you always think im talking about fuckin sea urchin

[mithotynochka]

@king4allstars as I told - I am not an expert in human fertilization, so I am not the right person to ask about this stuff :-)

[king4allstars]

@mithotynochka so you dont understand at all exactly like me

[mithotynochka]

@king4allstars Haha, I think I understand more then you do, but I admit that I don't understand a lot also. It's outside of my area of research.

Are you trolling me? How come you at 21 years don't know the basics of fertilization and that there are more then 1 sperm?

[king4allstars]

@mithotynochka i em 12 old and i dont know more things about fertilization

[mithotynochka]

@king4allstars aa, I see, that explains a lot. So, just google - you are right, it's always much better source of information )) Good luck!

[king4allstars]

@king4allstars ask google!

[uP1nThEStaRs]

whats that forming around the egg when the sperm is trying to get in?? it sort of looks like a barrier.

[mithotynochka]

@uP1nThEStaRs It is a fertilization envelope. Mostly it's function is to prevent polyspermy (entry of more then 1 sperm), but it also gives additional stability to the embryo.

In the sea urchins fertilization envelop is still present when the first cleavages occur, but after 15 hours or so the embryo "hatch" (it is called "hatching blastula stage") and start swimming

These creatures are using biology to come into shape and form. They are magnetic (gravity). They are in another dimension. We have to pierce deep through visible light and ultra-violet radiation to see them.
