The Best Month to Conceive a Boy
The best month to conceive a boy is October. And if you want a girl, April is the best month to conceive. (Mind you, we give no guarantees.)
This means more boys are born in the summer, while more girls are born in the winter. That's the word from a new study by Italian researchers published in the latest issue of Human Reproduction. Sex ratio is the number of baby boys compared with the number of baby girls. Previous research has focused on sex ratio at birth; this study is the first to look at sex ratio at conception.
The results: More boys are conceived when there is 12 hours of daylight and an average temperature of 54 degrees Fahrenheit. In our part of the world, October is the best month for conceiving a boy, while April is the best month for conceiving a girl. (It's just the opposite on the other side of the equator.)
Boys are the more fragile of the two sexes. They are more vulnerable in the womb and in the first few weeks of life. Conception in October means a summer birth. Researchers who made the discovery believe this is nature's way of giving boys a helping hand, ensuring that fewer boys are born during the harsh winter months, reports London's Daily Telegraph.
The research team, led by Dr. Angelo Cagnacci from the Policlinico of Modena, studied more than 14,310 births in Italy between 1995 and 2001. The ratio of boys and girls varied across the year. The Daily Telegraph reports that out of 1,000 babies conceived in October, 535 were boys and 465 were girls. But in April, the ratio was 487 boys to 513 girls.
"We could conclude from our data that if you want a boy in this region of the world, you would have a better chance if you tried to time conception between September and November," Cagnacci told the Daily Telegraph. "And, although the overall numbers of conceptions between March and May are lower than in the autumn, these are the months when you are more likely to conceive a girl."
