Laboratory and Success Rates
Aspire Fertility maintains in-house embryology laboratory capabilities at its Houston facilities. Laboratory quality — including culture conditions, incubator technology, and embryologist expertise — directly affects fertilization rates, blastocyst development rates, and embryo survival after cryopreservation. Aspire Fertility is a SART-member practice and reports outcome data to the CDC. Patients should request current, clinic-specific outcome data when consulting with Dr. Dunn or the Aspire team. Patients should also review the most current cycle-level data published by the CDC's ART Surveillance program and the SART Clinic Summary Report.
Patient Experience
The Texas Medical Center's Fannin Street corridor is well-served by Houston's MetroRail and is accessible from major thoroughfares including US-59/I-69 and Kirby Drive. Aspire Fertility's multi-location model in Houston gives patients flexibility in choosing a convenient site for monitoring appointments, while more specialized procedures may be centralized at specific locations. The practice's large patient volume brings a depth of experience treating a wide range of infertility diagnoses. Staff at Aspire Fertility's Houston locations are experienced in coordinating care for patients with complex medical histories, including those with prior cancer treatment, uterine anomalies, or severe male factor infertility. The TMC location's proximity to other hospital systems and subspecialties facilitates collaborative care when needed.
Considering At-Home Insemination?
Not every fertility journey begins in a clinic. For individuals and couples exploring their options before committing to a full IVF cycle, at-home insemination can be a meaningful first step. MakeAMom offers at-home insemination kits — including the BabyMaker kit for those with sensitivities, the CryoBaby kit designed for use with frozen or low-volume sperm, and the Impregnator kit for low-motility sperm — shipped discreetly to your door. With a reported 67% success rate among users, these kits provide an accessible, lower-cost entry point for those beginning their path to parenthood. MakeAMom's reusable kits are cost-effective compared to single-use alternatives and come with detailed instructions. That said, if you have a known fertility diagnosis, have been trying to conceive without success, or are over 35, consulting with a board-certified reproductive endocrinologist is the right next step.
Insurance and Financing
Texas does not mandate insurance coverage for fertility treatments, meaning that most Texas residents must pay for IVF and related services out of pocket unless their employer has voluntarily included fertility benefits. Some large employers in the Houston market — particularly in energy, technology, and healthcare — offer fertility coverage. Aspire Fertility has financial counselors who work with patients to understand coverage and out-of-pocket costs. The practice offers multi-cycle packages, financing through third-party medical lenders, and access to medication discount programs. Aspire Fertility's size and volume also gives it leverage with some pharmaceutical manufacturers for medication assistance programs.
Frequently Asked Questions
What is the difference between IVF and IUI, and how is the appropriate treatment selected? IUI (intrauterine insemination) is a lower-complexity procedure where prepared sperm are placed directly into the uterus around the time of ovulation. IVF is a more involved process involving ovarian stimulation, egg retrieval, laboratory fertilization, and embryo transfer. The appropriate treatment depends on diagnosis — factors such as tubal factor infertility, severe male factor, diminished ovarian reserve, or prior IUI failures often make IVF the recommended first-line option.
What does the Aspire Fertility multi-location model mean for patients? Aspire Fertility operates multiple clinics across Texas and other states. Patients may begin monitoring appointments at a convenient location near their home and travel to the primary clinic for procedures such as egg retrieval. The multi-location model is designed to minimize travel burden for routine appointments while centralizing specialized procedures.
What is single embryo transfer (SET) and why is it preferred? Single embryo transfer — transferring one embryo at a time — is recommended by professional guidelines including the American Society for Reproductive Medicine (ASRM) for most patients, particularly those with chromosomally normal (euploid) embryos confirmed by PGT-A. SET significantly reduces the risk of twin and higher-order multiple pregnancies, which carry higher maternal and neonatal risks.
Can Dr. Dunn treat patients who have frozen eggs or embryos stored elsewhere? Yes. Patients who have previously frozen eggs or embryos at another clinic can arrange transport of their cryopreserved material to Aspire Fertility for subsequent evaluation and embryo transfer cycles, subject to the receiving clinic's protocols and the sending clinic's release procedures.
