Does a sperms entry point substantially alter the developing fetus?

[lightbulb27]

Curious if science explored whether sperm entry point, angle and such influences fetus. Thus it isn't just about genetics, but other factors.

I'm aware it may change orientation of developing life, but does that correlate to anything in behavior and such?

The entry point of sperm into an egg does not substantially alter the development of the fetus in terms of genetic or phenotypic outcomes. This is why that is:

Once a sperm enters the egg, its genetic material is released and combines with the egg’s genetic material to form a zygote. This genetic combination determines the offspring's traits. The point of entry of the sperm does not influence this genetic combination.

The egg does have polarity (differences in its structure or contents from one region to another), and sperm entry can play a role in establishing axes of the developing embryo, such as the dorsal-ventral or anterior-posterior axis. However, these axes are influenced by broader biochemical and cellular processes rather than the exact site of sperm entry alone.

The sperm entry point may initiate cortical rotation in some species (e. g., frogs) to set up symmetry and polarity. However, in mammals, including humans, such effects are minimal or nonexistent. Human embryos typically regulate themselves to develop properly regardless of where the sperm entered.

Human embryonic development is robust and can compensate for variations in initial fertilization events. The exact point of entry does not directly determine specific traits or lead to substantial changes in development.

that's what I was looking for!

Glad to help - thanks for asking!

Sometimes the egg is outside the uterus and the pregnancy grows is in the tube's. Thats historically a death sentence without intervention.

What you're talking about is way more complicated.

Also just after 1 hour:30 minutes. I know it's Pokémon but it's using real-world biology evolution to explain complicated things.

Yes. If it goes into the mouth or during anal there won't be a developing fetus at all. So yes entry point makes a huge diffefence.

[lightbulb27]

ok... um... that's not the question. a sperm is.000001mm from an embryo...
then... does it matter where it enters?

[Opinion Owner]

You asked if the entry point alter something. These are entry points!

[Anonymous]

an egg is not developed until it is fertilized...

[lightbulb27]

yes. that's not the question...

[Opinion Owner]

And... and egg is designed to be entered as easily as possible so one could assume the answer to your specific version is "No effect"

[lightbulb27]

really? 22 million sperms, possible even billions over time can't get in. but one sperm is chosen. somehow, its a tough little embryo... is it... chemically choosy?

[Opinion Owner]

If you remember sex ed most die on the way. They aren't swimming around an egg in a swarm. It comes down to who's fastest in a small cluster of the best. They would just attack each other otherwise.

[lightbulb27]

I don't recall that...
and I wonder how the heck they know where to go... is the embryo sending a becon signal... or is it random.

[Opinion Owner]

I can only assume chemicals

[DrPepper12]

Good question. I would think not but good question!

FUN FACT: Teabagging your nads in hot water 20 minutes a day will naturally make you close to infertile...
☕ 👉🏻 🎱🎱 = 🚫 💦

[lightbulb27]

haha, thank you. I'm always thinking about something:)🤷‍♂️. I wondered if such might influence development, disposition. How much trauma it is to be attacked... by a sperm.. unless is welcome! Interesting... Yes, they have to be certain "cool" temperature to be effective... yet other cells warmer. Kinda weird given they swim in body temperature and the more heat, usually things vibrate more. So much I don't know. It's beyond amazing how we work.
So wait a second, if I do hot empsom salt bath every day for an hour... become infertile?
Being older, become more essential to deal with pain... which is likely where M. Tyson is right now... soaking in a tub!

I haven't read on this. But my brother is neurological handicapped because he lost blood to the brain at some point during the pregnancy.

[lightbulb27]

I'm sorry to hear that. That's a heavy load on the parents. I've seen other type challenges born with.

[lightbulb27]

similar such issue sent my parent into a religious tailspin.

[OddBeMe]

My mother def went Uber religious but luckily doesn't take to a certain group. So she's still manageable

[lightbulb27]

have to do something.. such issues challenge one to the core. there's a reason for the beliefs... rest of us should pay heed.

[OddBeMe]

Oh yeah I never harsh on her for her comforts. And she doesn't push her shit onto me. Very unique religiosity.

I developed swag...

[jshm2]

Yes. The egg actually "selects" the sperm, as well, by allowing it entry via a certain point only.

[Lynx122]

Yes it has to go in like a basketball shot to create the ultimate human :)

[Anonymous]

outside of taking drugs and other substances, the behavior of the child wouldn't be affected at all

[Kelley1]

Is there any reason it would make a difference?

[noohair]

Do you mean the back door?

[lightbulb27]

the embryo...

[noohair]

It was a joke... lol... lol...

[slatyb]

No, it does not.
