Predictor of child's sex : Conception Time
The BMJ features a study which says that longer it takes to get pregnant or conceive the sex of the child would be a male.

This study was performed by Dutch reserachers. The sample size was 5,283 women who gave birth to single babies between July 2001 and July 2003.

Among the 498 women who took longer than 12 months to get pregnant, the probability of male offspring was nearly 58%, whereas the proportion of male births among the 4,785 women with shorter times to pregnancy was 51%.

According to the researchers calculation states that, for couples conceiving naturally, each additional year of trying to get pregnant is associated with a nearly 4% higher expected probability of a male child being deliverd.

The explanation behind the study is that in viscous fluids sperms bearing the Y (male) chromosome swim faster than those bearing the X (female) chromosome as per the researchers. Women whose cervical mucus is relatively viscous would not only have more difficulties conceiving naturally, but also have a higher probability of male offspring if they do get pregnant.

This study is helpful but at the same time can be misleading !
