INVOcell device


Many patients struggling with infertility have difficulty undergoing in vitro fertilization (IVF) or other fertility treatments due to cost.

Our Houston, TX, practice uses INVOcell™ as a safe and effective option which can make fertility treatments more affordable.

So why should you consider INVOcell?

An Affordable, Safe  & Effective Fertility Treatment

A Holistic Approach

INVOcell is the first FDA-approved intravaginal culture (IVC) system that uses a woman’s body to support fertilization and early embryo development, rather than relying on a laboratory incubator.

Increased Affordability

Dr. Sonja Kristiansen is proud to lead the only facility in greater Houston certified to provide INVOcell. Using this method can help patients save about $4,000 compared to a round of in vitro fertilization.

Pregnancy Rates Similar to IVF

Clinical trials show that INVOcell pregnancy and live birth rates are comparable to IVF. In comparison to intrauterine inseminations (IUI), INVOcell has a pregnancy rate that is three to five times higher.

The INVOcell Procedure

The INVOcell procedure begins with the patient undergoing an ovarian stimulation cycle that is milder than the protocols associated with in vitro fertilization (IVF), allowing for improved comfort and reducing the risk of ovarian hyperstimulation (OHSS). Mature eggs are collected and placed into the patented INVOcell device, along with a sperm specimen.

The INVOcell device is then positioned in the vaginal canal to foster the initial phases of embryonic growth. Once incubation is complete, the device is removed and the embryos are inspected. Finally, one to two viable embryos (per ASRM limitation regulations) will be inserted into the woman’s uterus, and extra embryos can be frozen for future use.

INVOcell cycles are $6,300 (subject to change) each because this process eliminates the fees associated with lab incubation. Request an appointment to take advantage of our current cycle rate before time runs out.

A More Natural and Stable Incubation Environment

Since the entire INVOcell incubation phase occurs within the woman’s body, the factors required to sustain incubation - such as temperature and physiological pH - remain more constant. In a laboratory, the incubation environment may be subjected to regular interference, such as when the incubator doors open or close, or when the thermostat cycles. The INVOcell approach reduces the potential for fluctuations in the incubation environment.

Clinical trials show that INVOcell pregnancy and live birth rates are comparable to IVF. In comparison to intrauterine inseminations (IUI), INVOcell has a pregnancy rate that is three to five times higher.


The ideal INVOcell candidate may have blocked fallopian tubes or previous tubal ligation, ovulatory dysfunction, unexplained infertility or mild - moderate sperm abnormalities.  Candidates must meet eligibility requirements.

Although the success rates and potential savings INVOcell offers are attractive to many hopeful parents, it is important to understand that this option may not be right for every patient. For example, if a female partner has very high or very low levels of anti-müllerian hormone (AMH), low antral follicle count, or if severe male-factor infertility is an issue, INVOcell is not recommended. 

Hormonal evaluation, a saline sonohysterogram, and a semen analysis must be performed at the Houston Fertility Center to determine if you are a suitable candidate for INVOcell.  An INVOcell consultation with Dr. Kristiansen will provide you with your individual expectations of success with treatment and if INVOcell is right for you. 

You can depend on us to provide a thorough screening to determine which treatment is most likely to help you grow your family. We welcome patients from throughout greater Houston.
