They may be made up of slugs and snails and puppy dog tails, but plenty of parents would still love to complete their family with a bouncing baby boy.
The bad news is the odds of conceiving either a boy or girl or almost even for each and every pregnancy.
So girl or boy-heavy families have pretty much luck of the draw to thank for any gender bias.
A baby’s sex is determined at the time of conception.
However, as we learnt with tips to conceive a baby girl, there are few changes you could adopt which could increase your chances.
Some are rooted in myth, but other tips are based around helping “boy sperm” past the finish line first (so to speak).
Tips on how to conceive a boy
1. You should have sex in positions that allow for deep penetration
Dr Shettles, author of, How to Choose the Sex of Your Baby, believed that there were key difference between the different types of sperm.
There are the ones which carry the X chromosome (girl sperm), and one which carry the Y chromosome (boy sperm).
Boy sperm is characteristically weaker, smaller and faster than female sperm, which is overall tougher and better at survival (read into that what you will).
What Dr Shettles therefore believed, is that boy sperm benefits from a little head start – which more penetrative sex positions could help.
This would mean the boy sperm had less distance to travel and could therefore out-swim the girl sperm.
Suggested positions include you straddling your male partner, or having sex standing up.
2. Have intercourse as close to ovulation as possible
Timing is everything – including when trying to conceive.
The good news is, if you’re already trying for a baby, you’re probably already timing it around the days close to ovulation, as well as the day you ovulate itself.
Dr Shettle recommends having sex as close to ovulation as possible again because of the speed difference with sperm.
The male sperm can get to the patiently-waiting egg faster than the girl sperm.
If you have sex a few days before you ovulate, however, this gives the less resilient boy sperm time to die off.
3. Your partner should wear boxer shorts
Yes, now is the time to ditch the budgie-smugglers.
The reason being, a man’s choice of underwear could have an adverse effect on his sperm production. At least according to this old wife’s tale.
So, it’s believed male sperm thrives more if a man wears boxers, as this means the scrotum doesn’t get overly warm.
Male sperm, it seems, can’t take the heat and so wearing tight pants allows it a better chance of survival.
Female sperm, with its superior survival skills, is better suited to a “tight underwear” environment.
However, be aware that an overheated scrotum isn’t exactly good news for any sperm, be it male or female.
4. Orgasming before your partner during sex may increase your chances too
Apparently, whether a woman orgasms or not can have a bearing on the sex of a baby and could play a vital role in determining whether you conceive a boy.
The theory is when a woman orgasms, there is an alkaline-based secretion which is released into the vagina, and which boosts the survival chances of that boy sperm.
For this reason, you may also want to adapt to a more alkaline-based diet when trying to conceive.
So, to give the boy sperm a better chance, orgasming before your partner gives them both a head start and a friendlier environment.
5. Foods to avoid if you want to conceive a boy
- Spicy foods which contain vinegar, citrus juices and fruits and tart/tangy flavours.
- Avoid eating dairy foods such as milk, cheese, yoghurt and ice-cream.
- Eat more foods which contain potassium such as bananas, broccoli, potatoes, spinach and brussel sprouts.
- Some researchers believe that taking a daily supplement of Evening Primrose Oil boosts the chances of conceiving a boy.
