You can't guarantee a baby boy naturally, as it's determined by chance (XX for girl, XY for boy) at conception, but the only scientifically proven method is expensive IVF with Preimplantation Genetic Diagnosis (PGD) to select an XY embryo, though this is controversial and banned in some places. Natural methods, like the Shettles Method suggesting deep sex around ovulation for Y sperm (faster but shorter-lived), are not scientifically proven to work, with chances remaining about 50/50.
Gender is determined by sperm. Sperm that will create a female child are stronger and able to survive longer. Having sex closer to your ovulation increases the likelihood of a boy because there are more ``male sperm'' than if you ovulated days after insemination.
It is said that there a certain sex positions that increase your chances of having a boy. Deep penetration is said to be the best because male sperm don't live as long, so depositing them as close to the cervix as possible gives them the best chance to reach the mature egg first.
There is no sure-fire guarantee of having a baby of a particular gender. Hoping and trying for a boy or girl is just that, and does not influence the odds in either direction. One testicle does not produce girl sperm and the other boy sperm.
Men carrying a gene that leads to their sperm having more Y chromosomes have more sons. During times of war and large casualties of male soldiers, those families are more likely to have more surviving sons. And when those men have children, they, like their fathers, might be more likely to have baby boys.
The "3-3-3 Rule" for kids is a simple mindfulness technique to manage anxiety by grounding them in the present moment: first, name three things they can see; next, identify three sounds they hear; and finally, move three different parts of their body. This engages their senses, shifts focus from worries, and helps them regain control when feeling overwhelmed, like during test anxiety or social situations.
To conceive a boy, couples should have intercourse 4–6 days before ovulation. To conceive a girl, couples should have intercourse closer to ovulation day (2–3 days).
When we look at the statistics the chances of having a boy or a girl are almost the same and there's no medical evidence to suggest we can influence this.
The study found that maternal age played a key role in children's sex at birth. Women who began having children over age 28 were slightly more likely to have either all boys or all girls. Chavarro said these differences could be due to biological changes in women as they age.
So if they're hoping for a boy, the theory says, couples can try to have sex four to six days before ovulation. And to conceive a girl, they can hit the sheets either two to three days before ovulation or on the day the woman ovulates.
But in this study, women who had higher blood pressure and other signs of physical stress had four boys for every nine girls (ratio 4:9); while moms who were psychologically stressed had two boys for every 3 girls (ratio 2:3). All of the women had healthy pregnancies.
A study published today in Science Advances suggests that, far from a “coin toss,” some mothers may be biologically biased toward having children of one sex or another, with the effect seemingly increasing with age of first pregnancy and the number of children they have.
Shettles proposed that deep penetration during intercourse could be a factor in increasing the chances of conceiving a boy. Deep penetration allows the male partner to ejaculate closer to the cervix and uterus, helping the Y chromosome sperm reach the egg faster.
Speed: since sperm containing the Y chromosome are faster than those containing the X chromosome, if the egg is in the fallopian tube at the time of intercourse, there is a greater probability of a Y sperm reaching and fertilising it, which means there is a greater probability of the baby being a boy.

The "3-2-1 Rule" in pregnancy is a guideline for first-time mothers to know when to call their midwife or doctor for active labor: consistent contractions every 3 minutes, lasting 2 minutes each (or 1 minute long for some variations), for over 1 hour. It helps differentiate true labor from false labor (Braxton Hicks), signaling it's time to head to the birthing center, while subsequent pregnancies often follow the faster 5-1-1 rule.
It happens by chance, even if the sperm X-Y ratio is close to 50-50. It is possible there are some men who are slightly more likely to have male children, but even to the extent that this were true, the differences are small. There is nothing in the data that would suggest some men produce only boys.
Risks of having a baby after 35
The birth of a first baby is more likely to be complicated than having a subsequent baby, no matter how old you are. As people get older, the chance of other health issues rises. These health issues are what is relevant, and not the age by itself (Morris et al, 2018).
Here, using data from 740 British women who were unaware of their foetus's gender, we show that foetal sex is associated with maternal diet at conception. Fifty six per cent of women in the highest third of preconceptional energy intake bore boys, compared with 45% in the lowest third.
After digging into the history, theories, and science, the takeaway is pretty clear. The Shettles method doesn't have scientific backing, and neither do other natural gender swaying approaches. No matter how carefully you time intercourse or follow charts, your odds of having a baby boy or baby girl remain about 50:50.
For example, male pregnancies are more likely to be complicated by maternal gestational diabetes, and boys born from such pregnancies have a higher risk of congenital anomalies and respiratory disorders than do girls born to women with gestational diabetes (Persson and Fadl, 2014).
We now know that there's nothing you can do in the bedroom to influence whether you have a baby boy or a baby girl. Though there's a slightly greater chance you'll have a baby boy (due to the ratio of male to female births), sex positions, timing sex, and your vaginal pH have no bearing.
For healthy semen samples collected between 5:00am and 7:30am were found to exhibit a statistically higher sperm concentration, total sperm count and a higher percentage of normally shaped sperm, compared to samples produced later in the day. Sperm motility was not influenced by the time of sample production.
There's no evidence that tiredness means you're pregnant with a boy. Fatigue is a common symptom of pregnancy and has nothing to do with the sex of your baby.
