When seeking pregnancy, it is actually better to have sex a day or two prior to ovulation, as well as the day of ovulation. That way, sperm is in the vagina when ovulation occurs and the egg is viable. Sperm can survive in the vagina for up to 72 hours, whereas, after ovulation, an egg has the potential for fertilization for only about 24 hours.
Sex determination is based on how the chromosomes of the sperm divide when it fertilizes the egg. If the “X” chromosome is contributed to the egg, then the baby will be a girl. If a “Y” chromosome is contributed, then the baby will be a boy. There is a lot of information in books and online recommending ways to increase your chances of having a specific sex of child. Among these are special diets, certain foods and certain sexual positions. There is no evidence that any of these things really work.
