Hormone therapy litigation is technically demanding. Whether the case involves testosterone replacement, GLP-1 agonists, estrogen protocols, thyroid management, or peptide use, the standard of care questions are narrow enough that a generalist may not be the right fit. Finding the right expert takes more than a directory search.
This guide walks attorneys and insurers through each step of the vetting process: confirming credentials, evaluating publication history, assessing litigation experience, and understanding the tradeoffs between different sourcing channels.
Step 1: Confirm ABIM Board Certification Status
Why board certification matters in hormone therapy cases
Board certification from the American Board of Internal Medicine in Endocrinology, Diabetes, and Metabolism is the baseline credential courts and opposing counsel will scrutinize. An uncertified or lapsed expert invites a Daubert challenge before the merits of the opinion are even reached.
How to verify certification independently
Confirm a physician's ABIM certification status directly through the ABIM's public physician directory at certificationmatters.org. Look for both initial certification and maintenance of certification status. A candidate who passed boards decades ago but has not kept certification current is a weaker position than one who has.
Step 2: Evaluate Peer-Reviewed Publication History
What a PubMed search tells you
Search the candidate's name on PubMed and look for publications directly relevant to the clinical area at issue — not just general endocrinology. An expert in a testosterone replacement therapy case should have published on androgen physiology, hypogonadism, or TRT protocols, not primarily on diabetes management.
What to look for beyond volume
Relevance and recency matter more than a long publication list. A single 2024 paper on GLP-1 receptor agonist safety is more useful than a stack of papers on unrelated topics. Check whether the expert has published in peer-reviewed journals rather than conference abstracts, and whether those papers have been cited by others in the field.
Step 3: Assess Prior Deposition and Courtroom Experience
Why litigation experience is distinct from clinical expertise
A clinically excellent endocrinologist who has never been deposed can become a liability under cross-examination. Opposing counsel will probe the opinion's methodology, the expert's familiarity with the applicable standard of care, and any prior inconsistent statements from other matters. Time in the witness chair is not interchangeable with time in the clinic.
Questions to ask a candidate directly
Ask how many times the candidate has been deposed in the past three years, in what types of cases, and whether they have provided trial testimony. Ask whether they have worked for both plaintiff and defense — a one-sided history can be used to argue bias. Request a redacted list of prior matters if available.
Step 4: Confirm Subspecialty Match to the Specific Hormone Therapy at Issue
General endocrinology is not the same as hormone therapy expertise
Endocrinology spans adrenal disorders, pituitary tumors, bone metabolism, and diabetes, among other areas. A case involving compounded testosterone, off-label estrogen use, GLP-1 dosing errors, or thyroid hormone mismanagement requires an expert whose clinical practice and publications are concentrated in that specific area — not someone who can speak to the field broadly.
Subspecialty areas that come up most in hormone therapy litigation
- Testosterone replacement therapy (TRT) and male hypogonadism: cases involving cardiovascular events, erythrocytosis, or dosing errors
- GLP-1 receptor agonists: cases involving pancreatitis, thyroid C-cell concerns, or complications from rapid weight loss
- Estrogen and progesterone protocols: cases in menopause management, gender-affirming care, or fertility treatment
- Thyroid hormone management: cases involving overtreatment, undertreatment, or compounded thyroid preparations
- Peptides and regenerative medicine: an emerging area where both regulatory status and standard of care remain actively contested
An expert who has treated patients with the specific therapy at issue — and published on it — carries considerably more weight than one who can only speak to the field in general terms.
Step 5: Understand the Sourcing Channel and Its Tradeoffs
Directory listings (SEAK, JurisPro)
Platforms like SEAK and JurisPro maintain searchable directories of experts who have self-registered. They are useful for initial candidate identification, but they do not vet credentials, confirm publication history, or assess litigation track record. That work falls to you after you have a name.
Broker and referral networks (IMS Legal Strategies, Homestead Experts)
Firms like IMS Legal Strategies and Homestead Experts operate as intermediaries, matching attorneys with experts from their networks. They handle logistics and may pre-screen candidates, which can save time. The tradeoff is that the expert pool is limited to whoever is in their network, and the intermediary layer can slow communication and affect the working relationship.
Retained experts engaged directly
Working directly with a medicolegal practice means engaging the expert without a directory or broker in between. You can assess fit before retaining, communicate without delay, and build the kind of working relationship that supports a stronger written opinion and more confident testimony. The tradeoff is that initial sourcing is on you — which is what this guide is for.
Practical Vetting Checklist
Before retaining any endocrinologist as an expert witness in a hormone therapy matter, work through the following:
- ABIM board certification confirmed as current (certificationmatters.org)
- PubMed publications reviewed for relevance to the specific hormone therapy at issue
- Deposition and trial testimony history confirmed — frequency, case types, plaintiff/defense balance
- Clinical practice confirms active treatment of patients with the relevant therapy
- Expert can explain the applicable standard of care in plain language
- Written opinion process confirmed — methodology, timeline, deliverable format
- Availability for deposition and trial dates confirmed before retention
About Engaging an Endocrinology Expert Directly
For market context, the Expert Institute has reported that endocrinology expert witnesses typically bill between $356 and $478 per hour depending on the engagement type. These figures reflect broader market benchmarks and are not specific to any one practice.
If your case involves hormone therapy, peptides, anabolic steroids, GLP-1 agents, thyroid management, or related regenerative medicine questions, hormon.ai is the medicolegal practice of Dr. Fady Hannah-Shmouni, a board-certified endocrinologist who provides record reviews, standard of care opinions, and expert testimony to plaintiff and defense counsel, insurers, and regulatory bodies.
The right endocrinologist for a hormone therapy lawsuit is not simply the one with the longest CV. It is the one whose certification is current, whose publications address the specific therapy at issue, who has experience under cross-examination, and who can deliver a written opinion that holds up at trial. Use the checklist above to structure your evaluation, and inquire about your matter at hormon.ai.
