You can't guarantee conceiving a baby boy naturally, as it's mostly chance, but the only proven method is through Preimplantation Genetic Diagnosis (PGD) with In Vitro Fertilization (IVF) to select a male embryo, though this is often restricted or illegal for non-medical reasons. Old wives' tales like diet or timing intercourse don't work, but focusing on overall fertility and health is key, as sperm carrying a Y chromosome (for a boy) are thought to be faster but less resilient than X-chromosome sperm (for a girl).
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.
Best positions: deep penetrative sex is preferable. This helps to deposit the semen and sperm closest to the woman's cervix so they are given the best opportunity to get to the egg in the fallopian tube. Twelve hours before ovulation is thought to maximise the chances of conceiving with a boy.
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).
The both are correct. From ovulation day to two days after is for a boy.
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 diet should include vegetables and fruit, fish and seafood, nuts, seeds, whole-grain and fibre-rich products, poultry, and low-fat dairy products.
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.
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.
The ovulation gender theory proposes that the side you ovulated on correlates to your baby's sex. Specifically, if you ovulate from your right side, you're more likely to have a boy, and from your left, a girl. Some moms in the What to Expect Community have found that this was true for them.
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 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.
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.
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.
Diet Regulation
Some alkaline foods include spinach, tomatoes, carrots, fish, corn, papaya, and watermelon. There is also research suggesting that women who want to conceive a boy can consume foods high in potassium, such as bananas, sweet potatoes, and white beans.
Male Fertility Facts
Peak male fertility is around 25-29 years old. Sperm quality begins to decline at 30. At 45, men begin to experience a significant decrease in semen volume. Older men can also take longer to conceive a child.
Drinking and Smoking
Consuming alcoholic beverages lessens sperm count and concentration as well as the percentage of normal sperm. Smoking cigarettes can harm DNA, prompting sperm mutations. The bonus? Cutting back on alcohol and tobacco is good for general health as well as sperm production..
The proportion of male babies was significantly higher (65.5 +/- 3.9 per cent, mean +/- S.D.) in the offspring of women who resumed intercourse two days after ovulation. This proportion tended to be lower on or near the day of ovulation than on the previous one or two days.
The energy intake of pregnant women is about 10% higher when they are carrying a boy rather than a girl. Our findings support the hypothesis that women carrying male rather than female embryos may have higher energy requirements and that male embryos may be more susceptible to energy restriction.
Factors That May Affect Y Chromosome Sperm
Timing of Intercourse: Intercourse closer to ovulation might favor the faster-moving Y sperm. Diet & Nutrition: Consuming potassium-rich foods, zinc, and an alkaline diet may support overall sperm health and potentially the environment for Y sperm.
Signs of Unhealthy Sperm
Oranges and pomegranate juice both have high amounts of antioxidants and vitamins in them. The vitamin C found in oranges has been shown to improve not only sperm mobility and count, but also the morphology and overall health of sperm.
Low sleep quality, as assessed through the Pittsburg sleep quality index (PSQI), was found to negatively affect sperm concentration, while poor sleep duration (<6 h) had an impact on sperm motility [34].
