Will it Be a Boy or a Girl? Predicting and Influencing Gender

Can Timing of Intercourse Influence Gender Outcome?

At conception, gender is determined by chromosome characteristics - and it will be the male (or rather the male's sperm) that dictates whether the baby will be a boy or a girl.

Prior to conception, the unfertilized egg carries an X chromosome while the sperm can carry either an X or a Y chromosome. The gender of the baby comes down to one simple event:

If the sperm carrying an X chromosome fertilizes the egg, a girl will be conceived. If the sperm carrying a Y chromosome fertilizes the egg, a boy will be conceived.

Timing Intercourse

Studies indicate that the sperm with the X chromosome - or female chromosome - have a longer life span than the male sperm (with the Y chromosome).

Yet the male sperm appear to have a higher motility. Sperm motility is measured in two ways: percentage of sperm exhibiting movement, and the quality - or dynamics - of this movement, which is called the forward progression. Poor motility means the sperm have a difficult time swimming toward the egg. FertilAid for Men is a non-prescription male fertility supplement that has been shown to improve sperm motility.

Hence, "female sperm" exhibit less motility - yet have a longer life span. The "male sperm" exhibit increased motility, but have a shorter life span than the X chromosome sperm.

It is believed that if intercourse takes place closer to ovulation, then the probability is greater that the child will be male, due to the high motility (forward progression) and the decreased life span of the sperm.

The sperm with the X chromosome - or female chromosome - have a longer life span than the male sperm, but exhibit decreased motility. Therefore, intercourse that takes place earlier may provide increased probability of a girl.

After having 6 girls my partner and I finally had our son Dec 08...We used the sheattles method(sp). For boy you should start having sex on or as near to your ovulation as possible, for girl maybe a little earlier...14 days after the 1st day of your last period is when you should ovulate if you have regular 28day periods or 16days if you have a 32day cycle...

Eg.. LMP 28th may then you should ovulate on or around the 10th June if your a 28day cycle so for boy try to have sex from around the 8th,10th, june I would'nt recommend sex everyday as the sperm count will decrease, It's best to have sex every 2nd day so the day you dont have sex it gives the sperms time to build up in numbers again, for a girl you could start having sex from about the 4th,6th,8th..

If your a 32day cycle then youd ovulate on or around the 13th June(that would be about the 16th day after your LMP... So boy making would be around 14th,16th June & girl would be 12th14th16th June...

Well this theory worked for me & after having 6 girls in a row Im inclined to think this method does work...

Best of luck...

hi i got 2 little lads and would love a little girl.. i went on a ovulation calander today and seen im due to ovulate 8th i had sex today well early hrs of today at 12am (tuesday 4th) can i end up regnant so close to ovualtion starting iv read that if you have sex 3-4 days prior to ovulation, you have a better chance of conceiving a girl, because the weaker male sperm cells will die off, and the female sperm cells will be available in greater quantity when the egg is released. is this true am i likely to get pg

To the top question: Ur blood group has nothin 2 do with getting preg at all, Why was u woundering that?
I just found out in preg with our 4th baby, We have 3 boys! would realy love a girl but the desisoin has already been made now so i just wait till i hav 20week scan or when baby born.
Just keep trying to get pregnant it will happen, relax and enjoy the trying time Laughing out loud Getting preg u would think is easy as so many people hetr prg by accident but theres only a small % (cant remember what ) of 2 healthy people getting preg in 1 mth. Good luck x

Note that you are most likely to get pregnant if you time your lovemaking to occur on the days right before - and on - your ovulation date. Keep in mind that the projected ovulation date above is simply a “best guess” estimate based on your cycle date information. The most accurate way to pinpoint your most fertile time is through the use of urine-based ovulation tests or with a fertility monitor. We have partnered with Early-Pregnancy-Tests.com, the Internet’s leading supplier of preconception products since 2001, to offer low-cost, FDA-approved pregnancy and ovulation tests – with free same-day shipping.

 

Now that you’ve calculated your ovulation date using our ovulation calculator, we have a number of other helpful tools you can use to help increase your chances of conceiving.

 

  • Create your own personalized ovulation calendar! You can even provide an email address so that you receive email alerts of your most fertile days, when you can begin testing for pregnancy, and more.
     

  • Create your own personalized fertility chart! This is a highly accurate way to pinpoint your ovulation date that relies primarily on basal temperature charting. (Visit Early-Pregnancy-Tests.com for an accurate, inexpensive basal thermometer.)
     

  • Connect with others at our online community! If you have questions about trying-to-conceive – or if you just want to vent a bit – we have a wonderful, vibrant community of people who’d just love to hear from you.
