So I got bored with all the cervical mucus and basal body temperature stuff (I will go back and read it, after I finish reading the juicy bits) and skipped ahead to the "How to have a girl" chapter of How to Choose the Sex of Your Baby: Fully revised and updated
. Basically, it's harder to make girls than boys, unless your husband is really toxic and your vagina is really acidic. The science behind this is real, but more than I feel like explaining right now, other than to say that the "girl sperm" are much hardier than the "boy sperm" so they survive better under hostile conditions, such as hot, cramped tighty whities, men who spend lots of time underwater (scuba divers) or in the air (pilots and astronauts) or men with toxic jobs, such as anesthesiologists apparently. So basically, if we want to have a girl, DH can try to kill off all the "boy sperm" by being rather hot and toxic, or I can try to kill them off by being acidic...
