Physicians and Clinical Team
Dr. George M. Grunert is a board-certified reproductive endocrinologist and infertility specialist at Aspire Fertility. The board certification pathway for REI requires completion of OB-GYN residency followed by a three-year fellowship in reproductive endocrinology and infertility. Dr. Grunert's listing reflects his practice at the Aspire Fertility Houston TMC location at 7900 Fannin Street — a shared clinical address where multiple Aspire Fertility REI physicians practice alongside a unified team of embryologists, reproductive nurses, and clinical coordinators. The multi-physician structure at Aspire Fertility Houston provides patients with access to multiple specialists and ensures continuity of care across monitoring appointments, procedures, and follow-up. Aspire Fertility reports to SART and participates in CDC ART surveillance.

The laboratory supports a full range of procedures including ICSI, blastocyst culture, embryo biopsy for preimplantation genetic testing, vitrification, and comprehensive cryopreservation. As a SART-member practice, Aspire Fertility reports outcome data to the CDC, and patients can review these figures on the CDC ART surveillance website and the SART Clinic Summary Report database. Patients should request Houston-specific outcome data from the practice and evaluate it relative to national benchmarks for their age group and diagnosis. Patients should 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 on Fannin Street is accessible from multiple Houston neighborhoods via the MetroRail Main Street/Medical Center line, as well as from major freeways including US-59/I-69, I-610, and US-90. The TMC location is particularly well-suited for patients who need coordinated care across multiple specialties — for example, patients with chronic medical conditions affecting fertility, those requiring urologic workup for severe male factor infertility, or those with uterine or tubal anomalies needing surgical consultation. Aspire Fertility's multi-location model in Houston allows patients to schedule monitoring appointments at more conveniently located Aspire sites while returning to the TMC for procedures. The practice's financial counselors are experienced in helping patients understand their insurance benefits and out-of-pocket costs.
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 or have been trying to conceive without success, consulting with a board-certified reproductive endocrinologist is the right next step.
Insurance and Financing
Texas does not have a fertility insurance mandate, meaning that most Texas-based health plans do not cover IVF or other advanced fertility treatments unless the employer has voluntarily included fertility benefits. Some major Houston-area employers — particularly in energy, healthcare, and technology — do offer fertility benefits, and Aspire Fertility's financial counselors can help patients understand what their plan covers. For patients without fertility coverage, Aspire Fertility offers financial counseling on out-of-pocket costs, multi-cycle packages, and financing through specialty medical lenders. Medication assistance programs from fertility pharmaceutical manufacturers may further reduce overall cycle costs for qualifying patients.
Frequently Asked Questions
What is the Aspire Fertility network and how does it benefit patients? Aspire Fertility (Houston Fertility Institute) is a multi-location fertility network operating clinics across Texas and beyond. The network model allows Aspire to invest in shared laboratory infrastructure, clinical training, and quality benchmarking while offering patients multiple convenient locations for monitoring appointments. For patients, the network's size means access to a deep bench of clinical expertise and a large patient volume that supports continuous quality improvement in the laboratory.
What does a reproductive endocrinology fellowship train physicians to do? The three-year REI fellowship — completed after OB-GYN residency — provides intensive training in the diagnosis and management of infertility, hormonal disorders affecting reproduction, recurrent pregnancy loss, reproductive surgery, and assisted reproductive technologies including IVF, ICSI, and embryo transfer. Fellowship-trained REIs are the appropriate specialists for most couples and individuals pursuing fertility treatment.
How does Dr. Grunert's listing relate to the Aspire Fertility practice? Dr. Grunert's individual listing reflects his personal practice within the Aspire Fertility group at the TMC location. He is one of several REI physicians practicing at the Houston Fertility Institute / Aspire Fertility TMC site, and patients who schedule with Dr. Grunert specifically will be seen by him as their primary physician, though clinical support (nursing, monitoring, laboratory) is shared across the practice team.
Does Aspire Fertility Houston offer treatment for male factor infertility? Yes. Male factor infertility — including low sperm count, poor motility, or abnormal morphology — is commonly addressed through ICSI, a technique in which a single sperm is injected directly into each egg. Severe male factor cases — including azoospermia (no sperm in the ejaculate) — may require urologic evaluation and surgical sperm retrieval (TESE or MESA) before ICSI. Aspire Fertility coordinates with urologists experienced in reproductive medicine for these complex cases.
