Answer: Hello dear. Some beliefs which said to have helped the old wives on conceiving a boy :- Because male sperm is the faster of the two, so having intercourse as close to ovulation as possible. If you have sex several days before ovulation, then the less resilient male sperm may die off, leaving more female sperm to fertilise the egg. It is believed deep penetration was important to give the boy sperm a head start. With less difference to travel, the boy sperm would be able to outswim the girl sperm, and find the egg. As the belief goes, if your man wears boxer shorts, this is said to be better for male sperm, as the scrotum doesn’t get so warm, restricting the production of sperm. Tighter underwear are said to be better suited to the survival of female sperm. Some believe that during a female orgasm, an alkaline secretion is released into the vagina, which gives boy sperm an increased chance of survival. It is said that to increase your chances of having a boy, you should orgasm before your partner during sex. Hope it helps.
