How Gender Selection Works
In general, there is about a 50/50 chance of conceiving either a male or female child. A female parent carries an XX chromosomal makeup, while a male parent is XY. 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. At the Houston Fertility Center, we offer two methods for gender selection.
Gender Enhancement Wash
This practice has been performed in fertility clinics for over 30 years. During this process, a sperm sample is spun in a centrifuge, causing layers to separate based on density. This process sorts the dense X-sperm from the lighter Y-sperm. In addition, the sperm cells are separated from the seminal fluid so that irregular and abnormal sperm are eliminated.
Dr. Kristiansen has over a decade of gender selection experience. In addition to her skill and knowledge, she strives to deliver compassionate care to our patients.
Once this process is complete, the resulting sample is more likely to lead to pregnancy, while also increasing the chances for the desired gender. Once the sperm sample is washed, it can be used for the intrauterine insemination (IUI) procedure only.
Generally, sperm sorting methods can result in 70-85% female and 60-75% male. Although we offer this service, it is not FDA approved because it is widely considered an unreliable method to obtain the desired gender in addition to having lower pregnancy rates. INVOcell or IVF with PGS are the only current methods to reliably determine pre-implantation gender and have higher pregnancy rates.
In Vitro Fertilization and INVOcell
Another popular option for gender selection is in vitro fertilization or INVOcell™ with preimplantation genetic screening (IVF or INVOcell with PGS - also known as PGT-A). Although this method is more expensive compared to a gender enhancement wash, it is by far the most predictable option.
During IVF, eggs are harvested from the female and sperm is taken from the male. The eggs are fertilized in a laboratory, where the embryos will develop for three to five days or within the body for INVOcell. Once the embryos have matured, a biopsy will be performed to test for gender before they are implanted into the uterus during a frozen embryo transfer. This method allows only the embryos with the preferred sex to be transferred into the woman’s uterus.
