Your chances of having a boy are slightly higher than 50%.
Understanding the Odds
While often simplified to a 50/50 chance, the reality is that the sex ratio at birth is slightly skewed towards males. According to the World Health Organization (WHO), the ratio of male to female births is approximately 105 to 100. This translates to approximately a 51% chance of having a boy.

Several sources confirm this slight bias towards male births, citing various competing theories for this phenomenon. [Source: Reddit ELI5 thread, Veritas International blog post].
Factors Influencing Gender
While the sperm (carrying either an X or Y chromosome) determines the baby's sex, the probability remains inherently close to 50/50. The slight male bias observed globally doesn't significantly alter the chances for an individual couple.
Beyond Simple Probabilities
Some methods claim to increase the likelihood of having a boy or a girl, but the effectiveness of these methods remains scientifically debated. Timing of intercourse is one factor sometimes mentioned, but its impact is minimal. [Source: Huggies Australia]
It is crucial to remember that each pregnancy is an independent event. Having a boy or girl in a previous pregnancy does not influence the sex of subsequent pregnancies. [Source: Quora discussion on having a girl after having a boy]
