Lh Surge Before Ovulation

Carol asks…

Had sex 18 hours before detecting LH surge – Will it be a boy or a girl?

Just found out I’m pregnant with third. As I have two boys, I have been trying to follow the Shettles method to get a girl. That is, to have sex 2-3 days before ovulation. (To get a boy, you have sex the day before and the day of ovulation). I have been tracking my cycle using the Clearblue Fertility Monitor and normally have 3 HIGH days, followed by 2 PEAK days. I had sex on my second high day that night, and then the next day it had the third day of HIGH on the monitor. However, I did an additional Ovulation Predictor test at 2.30 pm the day after I had sex, and it showed it had detected the LH surge. Therefore, I had had sex about 18 hours before detecting the LH surge, and then ovulation occurs normally 24-36 hrs later.

Just wondered what you thought if it would be a boy or girl? Please no answers about just being grateful I’m pregnant. I am – I want a healthy baby above all else, but just wondered whether it’s more likely to be a girl than a boy?
The reasoning behind having sex BEFORE ovulation for a girl, is because the male sperm don’t live as long, so by the time you ovulate, they should have died off, leaving the female sperm there to fertilise the egg. Male sperm swim faster but die quicker (hence doing it at ovulation to get a boy) whereas girl sperm swim slower but live longer.

Sorry for the wacky answers, I don’t think these posters are familiar with the Shettles Method.

Anyway, based on the Shettles Method your chances sound pretty good for a girl this time. Having sex 18 hours before your LH surge and then the surge itself means you are still 12-48 hours away from ovulation (with an average of 24 hours) means you gave those girl sperm plenty of time to reach that eggie and girl sperm live longer so there would have been girl sperm waiting for that egg by the time you ovulated–possibly 2-3 days later.

Good luck and congrats!!

Susan asks…

Can you miss the LH surge?

Is it possible to have missed the LH surge before ovulation if you tested at 10 am in the morning every day?

No  

Jenny asks…

I had sex day before before ovulation test detected positive LH surge could I be pregnant?

I had sex on the wednesday morning and detected the LH surge on the thrusday afternoon. My partner went away and we did not have sex for 72 hours. I understand that it is best to have sex with 48 hours after a positive test detects an LH surge. However, I have read that sperm can survive up to five days in the womb and am confused as to my chances of falling pregnant. My period is due next week.

How hopeful can I be??? What are my chances of falling pregnant???
HELP!

Betty asks…

So ovulation prediction kits detect your LH Surge, which happens 12-36 hrs before ovulation…?

What happens during ovulation, will a test show the 2 lines or none at this time?

Pregnancy Advisor’s answers:

Most likely it will show a neg result. LH surges right before ovulation and then quickly goes back down. So typically, by the time the egg is actually being released the LH is low and won’t register a positive on a test.

Mary asks…

Had sex 18 hours before detecting the LH surge – will it be a boy or a girl?

Just found out I’m pregnant with third baby. As I already have two boys, I have been trying to follow the Shettles method to have a girl. I have been using the Clearblue Fertility Monitor to track my cycle. I normally have 3 HIGH fertility days followed by 2 PEAK days. I had sex on my second day of HIGH. The next morning the Fertility Monitor still said HIGH. However, I took a separate Ovulation Predictor Test at 2.30 pm on second day of High and it had detected the LH surge. Therefore, I had sex about 18 hours prior to picking up the surge. Ovulation then comes about 24 hrs later.

Of course I am happy to be pregnant, and want a healthy baby above all else, but just wondered if you think it’s more likely to be a girl.

The Shettles method suggests having sex 2-3 days before ovulation for a girl, and within 24 hours prior to ovulation for a boy (the day before and also on the day of ovulation).

Thanks!
The reasoning to have sex BEFORE ovulation for a girl, is that the male sperm swim faster but die off quicker (so they should have died off by the time you ovulate when the egg comes). THe female sperm swim slower, but live longer. Therefore to get a girl, the female sperm will be alive longer to fertilise the egg.
I KNOW it’s the sperm that decides the sex of the child, but the timing of intercourse in relation to ovulation also plays a part as male sperm swim faster to get to the egg but don’t live as long as female sperm. So if you have sex when you ovulate, the male sperm should get to the egg before the female sperm as they are slower, but live longer. That is why it’s recommended to have sex BEFORE ovulation to conceive a girl, as by then , the male sperm should have died off.

The Shettles method is supposed to raise your chances to 75%. It would be 50/50 otherwise.

THANKS
