Sex at a certain time for a boy or girl

I had a woman suggest Shettles to me years ago, which she tried herself but ended up having two boys. So in her case, not a reliable method.

There are so many reasons why certain sperm may not reach the egg and even of those that reach it, only one can get inside. I honestly think the whole thing is just a big pot of randomness and not worth thinking about too much!

I’ve got a son and miscarried my daughter. My son was conceived on day 13 and I think my daughter was conceived on day 12.

I don’t know the gender of my other pregnancies.

It is not fact that male sperm swim faster, it's nonsense. There's some evidence that diet may have a tiny effect, like making it 51/49 instead of 50/50, but really it's like flipping a coin.

I know 4 different couples who have followed these rules and got the baby of the genders that they tried for.

It's a load of rubbish, an old wives tale. There is no way to engineer yourself to have a specific gender, it's not possible. Sorry.
What are you basing your opinion on? It’s a medical fact that male sperm tend to swim faster.

So why is it so far fetched that you can manipulate this to increase your chance of one sex over the other?

Merrz, surely though that's just that the odds were in their favour. After having three of one sex statistically you are more likely to have the other with a fourth. That's not always how it is but statistics were on their side. I will admit though I really hate the whole trying for a certain sex. You have a baby, just be happy.

Well we just literally had sex all the time. Once a day, sometimes twice when I came off the pill. We were lucky and conceived first month of trying each time and the order went girl, girl, boy. By what people are saying we would have had more chance of having all boys. I think you just get what you're given

My friend had 3 girls and they were desperate for a boy, they both changed their diets for a few months before ttc and timed sex for a boy. According to her you can't guarantee but male and female sperm do better in different environments so you can make your body more favourable for one or the other. Guess what . . . they had a baby boy.

I have three big brothers and Mum says she ‘made sure’ I was a girl!

Actually forget the ratios - I remember that was also to do with the fertility treatment sperm cleaning process. But the principle is the same.

Apparently girl sperm lives longer but boy sperm is faster so if you do it a few days before it's more likely that the girls will be alive but if you do it on ovulation day you're more likely to get a boy
This is what my fertility nurse told me and she should know. But it’s a numbers game and there are billions of sperm. So although you can affect things slightly you’re only shifting likelihood- I think the ratios she mentioned were something like 50/50 to 60/40.

I haven't mastered how to have sex and get a baby let alone boy or girl...this is like expert level conception haha

I read before that most "accidents" are boys as the male sperm swim faster. From the kids I know who were unplanned the majority are actually boys. In order to conceive a girl then you are supposed to have sex before your fertile period to allow male swimmers to die off and the female swimmers to arrive just in time!

Compiled not complied!

The most reliable site for this is genderdreaming. I know the woman who runs it has complied results from her members and drawn conclusions. A lot of it goes against all the old stuff like Shettles which now has been disproven. She recommends "one try" for conceiving a girl, which is most easily achieved by having sex only every 4 days. Not sure what she says for a boy. Almost everything she recommends for TTC a girl also lowers chances of pregnancy in general. I'm not a member but it's a really brilliant website with some really good new theories.

I read recently that this theory was rubbished and there's no actually evidence/proof.

I vaguely glanced at a "gender swaying" group on another online forum and there were lots of different boy/girl methods but even there they said the Shettle's method wasn't proven though plenty of people still try it.

It fascinates me tbh.

There’s zero science to show this actually works. The shettles method is a load of rubbish. You can try it if you’d like but I wouldn’t rely on it

You are more likely to conceive a boy earlier in your fertile period than a girl. But the differences at an individual level are so infinitesimally small as to make no difference to a couple. The differences are seen at a population level.

Interestingly cows are the other way around.

There’s no hard and fast way of deciding sex without sperm sorting.

There are intriguing hints that certain social, nutritional conditions etc can subtly tweak the sex ratio. But you’re talking about billions of sperm so the chances of itvworling for you don’t stray much from 50:50 atcthe individual level :)

There are studies of red deer on the island of Rum and of the Seychelles warbler if you’d like to read more about sex ratio skewing. Birds can do it, red deer can do it (to a degree.)
