Making a Girl

Lara and I have decided to have a second child. We're hoping for a girl this time around, so we poked around on the web for some advice on how to make it happen.

From: http://www.babyhopes.com/how-to-conceive-a-girl.html

Frequency and Timing of Intercourse:

Shettles says in order to increase the chances of having a girl, you should have sex everyday from the end of your period up to 2 1/2 to 3 days before ovulation. After this point, do not have unprotected sex until several days past ovulation.

Intercourse further away from ovulation favors the larger slower moving X (girl) sperm. The weaker Y (boy) sperm will die more quickly in the more acidic preovulatory vaginal / cervical secretions and by the time of ovulation there will be a much larger concentration of X (girl) sperm available to fertilize the egg.

Sexual Position:

Shettles suggests that if you are trying to conceive a girl, shallow penetration from your partner, preferably with the missionary position, will deposit the sperm closer to the entrance to the vagina. This area is more acidic than closer to the cervix and acidity will work against the weaker "boy" sperm leaving more "girl" sperm available to fertilize your egg.

Sex and Orgasms:

When trying to conceive a girl, Shettles recommends that you don't orgasm during sex as the body produces substances after orgasm that makes the vaginal environment more alkaline, which favors the "boy" sperm.

The contractions which accompany an orgasm help move the sperm up and into the cervix, giving the "boy" sperm an extra chance at being available when your egg is available for fertilization.

Other links and words of advice welcomed.

We've decided to stick to the tried and true method practiced by all of our ancestors.

Hmmm...I don't want to rain on your (or anybody else's, for that matter) parade, but from some of my bio-ethical studies (ethical issues abound about the limits society might want to place on trait-selection) I've read/over-heard a bit about these types of conceptive tips are pretty much bunk...I have yet to read any solid studies that prove that position/time of attempted conception/diet/etc. have any consistent effects. I would be EXTREMELY wary of the multitude of psuedo-science books that exist...they often make claims of technique success despite lacking any serious experimental research. Websites are even worse as many of the "health" websites are merely covers to promote specific agendas - they commonly spread mistruths about proven techniques (see below) so that you buy their product. :::sighs:::

In vitro fertilization can pretty much assure a child of the gender you desire. However, it is rather expensive and requires a rather invasive surgery to retrieve egg cells.

A surgery-less option does exist: There are certain companies (I'm not sure if there are any in the states, I think I heard about these in an Australian publication) that will take a sample of your sperm, put it in a high-volocity centrifuge...the centrifuge will seperate the slightly different weighing-sperms and then you can attempt fertilization with the sperm group you want.

And, finally, there apparently is a new technique - MicroSort - that I've just read about, a link to a small article about it is here:

Regardless of whether any of this is at all useful, I wish you both good luck!
