Right or left ovary produces boys/girls??

[kittenpeak]

Went for a viability scan today (8+1 and all went well) and the sonographer said that it was likely I became pregnant through my right ovary.

Pretty cool I thought as I had huugge pain on my lower right side and a couple of months back so presuming it was mega ovulation pain!

Anyway, she noted it on the form, and I googled it (just wondering if there was any relevance to it, and wondered why they would need to bother putting it on the report) and it says that the right ovary is the one which tends to release eggs more frequently, and if fertilised, it's likely to be a boy.

Did anyone else know this? I think gender was determined by the sperm?

Congratulations on your pregnancy OP!

This seems a bit odd, as you say, I’ve always thought gender was determined by the sperm. My sister only has one ovary and has a boy and a girl!

Nope. Gender is determined by sperm.

You can find a lot of weird shit on google.

Sex - not gender - is determined by the chromosomes of the sperm that fertilises the egg.

Congratulations on your pregnancy OP.

I too only have one functioning ovary (my left) and have 2 boys & 1 girl .

I’m not sure where that theory comes from, but I’m pretty sure your odds are still 50/50.

Google is wrong on this one. Sex is determined by sperm. All eggs have one X chromosome. If fertilised by a sperm with an X chromosome, it becomes an xx fertilised egg, which will develop into a female. If fertilised by a sperm with a y chromosome, you get an xy fertilised egg that will develop into a male.

For weird anatomical reasons (your body is not totally symmetrical), you are more likely to conceive from an egg released on the right because it has a quicker and easier journey to the uterus. I don’t think there is any link to sex whatsoever though as that’s determined by the sperm. FWIW I’ve conceived twice from right ovary, one boy and one girl.

Gender has nothing to do with our ovaries, all our eggs are X chromosome so all girl chromosomes, so the gender is 100% defined by if a x sperm (girl) or boy sperm (boy) fertilises it, basically biology

Congrats, but your ovaries are only producing XX chromosones. Sperm produce XY, so they determine if the foetus is male or female. Its nothing to do with you ovaries!!!

A tad concerned at the state of science education in this country 😳 Sperm determine whether babies are male or female, eggs are all neutral.

While we're on the topic, no, one testicle doesn't produce male sperm and the other female 🙈

Thanks all!

Not that I mind at all, I just wondered if what I'd read was true! I was certain it was always determined by the sperm.

Also, if it is possible to know what sex based on the ovary it's quite inappropriate to tell the woman without her say so, as kinda gives the game away!

Thanks for the info! Would be interested to hear from
Others, ie what gender they had from what ovary

I thought I had read that Y sperm are a bit more "fragile" than X sperm. If an ovum has a shorter distance to travel from the right ovary, might it not be true that more Y sperm might have a chance of reaching it then if it were the left ovary?

Not that I think it would make any difference, but I ovulated from my left ovary and I'm having a boy 🙈

Interesting point, maybe that's it.

I ovulated both times from left and ended up with two boys

As others have said, sex is determined by the sperm that fertilises the egg, not the egg itself.

Ovaries have nothing to do with it 🤣🤣
What side the baby implants on though - supposedly it's left for a girl and right for a boy......

Hahahahahaha

Gender has nothing to do with biology whatsoever.

Eggs have a X chromosome, sperm have a X or Y chromosome.

That is it. Nothing to do with ovaries or where it implants for anything else. I mean issues can arise which is why variants in XY or XX happen but that is biology for you.

A lot of people on here saying that a baby's gender is determined by the sperm, this is half right. In fact, the pH of the vagina determines (to a great extent) which sperm (X or Y) will win the race. In an acidic pH (5.5), more X-chromosome-bearing spermatozoa were able to thrive, while a more alkaline pH favours the survival of Y-chromosome-bearing spermatozoa. the pH of the vagina is mostly determined by diet, so you can (theoretically) choose the sex of your baby by modifying your diet whist TTC.

@kittenpeak Hi OP! Did you find out what you were having? Just intrigued as I had my scan today and they also said right! I agree with all the above but just thought I would ask ☺️

Hi did u find out what u were having?

I research in a closely related area and the evidence is strongly mounting against the idea that the egg is a passive recipient of the sperm. There is compelling evidence that the egg selects the sperm it prefers to enter it based on compatibility with the egg, which makes good evolutionary sense and also leads to surprising results that defy mendelian inheritance. Also the left and right ovaries are different, the eggs are matured in different hormonal mixes in each and different levels of follicular fluid so it may be that some eggs are more likely to select male or female sperm. Also the anatomical differences between left and right ovary may lead to the egg being more favourable to one or other sex chromosome. I think this is less compelling as while 10% of make sperm are faster, but die quicker but in the time spans involved in conception on average you would expect things to even up between male/female sperm. It appears true that the nutritional and health condition of the mother and her stress levels has a statistical bearing on the sex of the offspring so this is further selection on the part of the maternal reproductive system (father's age etc also effects his sperm, male sperm is more easily damaged and more likely to struggle to penetrate/be accepted by the egg.) Men present the sperm of both chromosomes, and some men may have more of one than the other, the research is still a bit ambiguous there but it appears probable, but the egg has a say in the matter too.

@greekyogurtaddict That's so fascinating!

My egg came from my right ovary and I am indeed having a boy!
