How Does Gender Selection Work?

Just a few years ago, if you would have mentioned paying big bucks to influence or select the gender of your baby, people would have thought you were crazy. Not anymore! The gender selection industry is booming, and it is a multi-million dollar industry these days! Today’s parents know what they want, and they are prepared to pay to get it. Today we are going to explore gender selection a little bit more and find out more about how this practice actually works. Claim Your 20 Free Pregnancy Tests – Click Here

Preimplantation Genetic Diagnosis

PGD, or Preimplantation Genetic Diagnosis, is by far the most effective means of gender selection available today. However, that also comes at a very high price. GPD is almost 100 percent effective, which is astonishing, but not as astonishing as it’s $20,000+ price tag! PGD uses IVF technologies, but the scientists also check each embryo and test it for gender before implanting it.

PGD does almost 100 percent guarantee that you will get pregnant with your desired gender, IF you do get pregnant. There is no guarantee that you will get pregnant, however. You do, however have to make a decision about what you want to do with the embryos of the undesired gender, which raises some important ethical and moral concerns.


MicroSort is one of the newer gender selection methods on the market today. MicroSort is a dye based method, and it is pretty effective. The success rates are around 90 percent when it comes to choosing girls and around 75 percent when it comes to choosing boys.

MicroSort works off of the premise that “girl” sperm are bigger than “boy” sperm. The sperm is colored with a dye and then a laser is used to make the dyes light up. The bigger “girl” sperm will glow brighter under the laser light, and the sperm are then sorted by brightness. The preferred sex of sperm is then inserted into the uterus via artificial insemination.

Because this method uses AI instead of IVF, it can be much cheaper, and has fewer health risks and side effects. However, MicroSort is a relatively new process and has not been approved by the FDA. While success rates are pretty high, there are no guarantees with this type of procedure, since the boy and girl sperm are still together when sorted, and can not be completely excluded.

Microsort is pretty expensive, starting at around $3000 and they do have some strange rules. You, or your egg donor, must be under 39 years old, you must be married and already have one child, and want a child of the opposite gender. There are also only two MicroSort centers: one in Virginia and one in California.

Erricson technique

This one has been around for over forty years, and is relatively “low-tech” and inexpensive when compared to other gender selection methods. The Erricson technique attempts to separate the faster swimming boy sperm from the slower swimming girl sperm.

This is done by pouring a sperm sample onto a layer of sticky fluid inside a test tube. The boy sperm will reach the bottom first, the girls will be farther up in the test tube, and the two genders of sperm will be separated, and you are then inseminated with the gender of your choice.

Sounds simple enough right? This method is not as technologically advanced as other methods, and because of that, it is cheaper, at only around $600 per treatment. While this treatment method claims to be as much as 75% effective, some scientists argue that the success rate is more like 50 percent.

The bottom line

These are the most popular methods of medically assisted gender selection that are done in a doctor’s office setting. There are a ton more at home methods that some people try, but no one really knows how well they work. It is just amazing that we have these options in this day and age where you can actually choose which gender baby you would like to have. Back in the olden days, you just got pregnant and it was a surprise. Now, technology can help you how to conceive a baby girl or how to conceive a baby boy.
