Common Reasons to Consider Gender Selection

Because every family is unique, each will have their own reasons for pursuing gender selection. The two primary motivations for choosing this treatment are:

Family Balancing

Some parents who already have a child of one gender may wish to have a child of the opposite gender. Sex selection can help those parents achieve the family dynamic they desire. In some cases, patients may have certain social, economic, or personal reasons for wanting to have a child of a specific gender.

Genetic Disease

Some couples have genetic diseases that they do not want to pass on to their children. For example, hemophilia and muscular dystrophy are sex-linked disorders that mostly affect male offspring. Therefore, any couples with these medical concerns may choose to have a female baby.

Sex Selection Can Reduce the Risk of Passing on These Gender-Linked Diseases



Hemophilia is a medical condition that reduces the body's ability to properly form blood clots. Because people with hemophilia have trouble forming blood clots, even a slight injury can cause severe bleeding. Most types of hemophilia are inherited, and most cases occur among males. According to the Centers for Disease Control and Prevention, hemophilia occurs in approximately one out of every 5,000 male births


Muscular Dystrophy

Muscular dystrophy causes muscle weakness and loss of muscle mass. Muscular dystrophy diseases are passed on genetically, mostly affect boys, and have no cure.

Fragile X Syndrome

Fragile X syndrome is another genetic condition that affects males more severely than it affects females. Fragile X causes a range of developmental problems, including learning disabilities.

Understanding How Gender Is Determined

In general, there is about a 50/50 chance of conceiving either a male or a female child. A female parent carries XX chromosomes, while a male parent carries XY chromosomes. Therefore, the male parent can contribute an X chromosome or a Y chromosome. If an "X" sperm fertilizes the egg, a baby girl is conceived. In contrast, if the sperm that fertilizes the egg is a "Y," the offspring will be male. 

Preimplantation Genetic Screening/Testing

Our fertility center utilizes the latest tools and techniques to help hopeful parents achieve their family goals. We use a genetic testing method known as PGT to identify whether embryos are XX or XY. This allows us to select which embryos will be placed into the woman's uterus to achieve pregnancy with your desired gender. PGT is performed with either IVF or INVOcell. These methods have success rates that compare well to the national average, making them a safe and reliable option for sex selection.

What Is the Cost of Sex Selection?

Our clinic understands that the cost of fertility treatment can be significant. We try to make treatment as affordable as possible and offer several financing options to help offset the cost of care. Our warm and friendly staff are always willing to walk you through the process and answer any questions you may have.

Which Method Should I Choose? Comparing IVF and INVOcell for PGT


IVF is the process of joining eggs and sperm in a laboratory setting before transferring the embryos back to the uterus. PGT is performed before the embryos are transferred to the uterus.


INVOcell relies on a woman's body rather than a laboratory to support fertilization and embryo development. It is more affordable than traditional IVF, but it boasts similar success rates.

The Treatment Process For IVF and INVOcell 

IVF and INVOcell with preimplantation genetic screening are currently the most reliable gender selection options with high pregnancy rates. During these processes, you can expect:

Ovarian Stimulation

The woman goes through the IVF or INVOcell cycle, beginning with ovarian stimulation. The injectable hormone medication results in the production of multiple eggs a month.

Egg Retrieval

The eggs are carefully retrieved one by one using gentle suction. The patient is anesthetized during this procedure to ensure her comfort at all times. 

Fertilization & Embryo Development

The eggs are mixed with sperm, allowing fertilization to take place to form an embryo. The embryos will develop for three to five days in the laboratory or within the body using INVOcell.

Genetic Testing

Once the embryos have matured, a biopsy is performed to test for gender using PGT. This allows us to identify which embryo has the desired chromosomal makeup for sex selection.

Embryo Transfer

The selected embryo of the preferred sex is implanted into the female's uterus during a frozen embryo transfer.


After about two weeks, a pregnancy test is taken at our fertility center to determine if IVF or INVOcell with preimplantation genetic diagnosis was successful.

Understanding the Role of Gender Enhancement Wash

For the gender enhancement wash method, a sperm sample is collected and spun in a centrifuge, causing layers to separate based on density. The dense X-sperm is distinguished from the lighter Y-sperm. This method may only increase the odds of conceiving with the desired gender when used with the intrauterine insemination (IUI) procedure. Although this is a safe procedure, this method is considered unreliable for gender selection and is not FDA-approved.

Electing this treatment option requires all services, including testing, to be performed locally at the Houston Fertility Center.

Gender Selection FAQs

How is gender selection performed?

Dr. Kristiansen can perform gender selection with preimplantation genetic testing (PGT). PGT is performed in combination with IVF or INVOcell.

What is the success rate for gender selection?

IVF and INVOcell have good success rates compared to the national average, making them reliable options for parents thinking about gender selection.

How much does the treatment cost?

The cost of gender selection will depend on which technique you choose and other factors. Our Houston fertility office is equipped with all of the technology needed to perform gender selection on-site, which can make the process more affordable.

Dr. Kristiansen and all the staff are great. We went in for a RIVF consultation and due to the way they treated us and made us feel we decided to begin the process as soon as we were able to. We will always be thankful to Dr. Kristiansen, Blanca, Melissa and especially Mayra they are all amazing, they helped us with our thousand questions and doubts and when we felt discouraged they kept our spirits up. Thanks to them we are now expecting our precious baby girl. We definitely recommend Houston Fertility Center.

I love this place and Dr. K has a high success rate. This is why I initially went to her clinic. They don’t treat you like a business but it’s very personal. I was successful on my first IVF attempt and had a healthy baby girl. I will be using her for my next baby when I’m able. Highly recommended.
