This came up in a discussion I was having with a cousin of mine (who's going to have a baby soon). She said that the time of conception influences the sex of the baby, and gave me the following link : http://www.childbirth.org/articles/sex.html It sounded kinda dubious to me, so I bring it to you. Is there any truth to this ? Some other factors mentioned are pH, sperm count and temperature. I know that temperature influences the sex of amphibian offspring, but hadn't heard of any studies on humans. So what's the verdict : bogus or not ?
