A hormone pellet insertion takes about 10 to 15 minutes. You lie on your side, the upper outer hip is cleaned and numbed with local anesthetic, a small incision of a few millimeters is made, a trocar places the pellets into the fat layer under the skin, and the site is closed with adhesive strips rather than stitches. Most people drive themselves home afterwards, and the pellets dissolve on their own over roughly three to six months. Here is the appointment start to finish, plus the parts of pellet therapy that deserve a plainer conversation than they usually get.

Before the day: labs and the decision itself

Nobody should get a pellet on a first visit. The insertion is the last step of a workup, not the first.

For men, the Endocrine Society’s 2018 guideline on testosterone therapy asks for symptoms plus consistently low morning total testosterone on more than one occasion, along with hematocrit, PSA where appropriate, and anything that would make therapy a poor idea. For women, the conversation is about symptoms, cycle status, and the goal of treatment. Our piece on what a full hormone panel actually measures covers what belongs on that lab order.

Three things to sort out before you book:

  • Blood thinners and aspirin. Tell us. We usually do not stop them, but we plan for more bruising.
  • Your calendar. Do not book an insertion the week before a beach holiday, a long swim or heavy leg day. The first week of activity is the part you control, and it matters.
  • Skin at the site. An active rash, infection or recent tattoo over the upper outer hip means another site or another day.

The appointment, step by step

  1. Consent and marking. We confirm the dose, the pellet count and the side. Most clinicians alternate hips between insertions to let tissue recover.
  2. Positioning. You lie on your side with the upper hip exposed. Nothing below the waist is uncovered.
  3. Sterile prep and local anesthetic. The skin is cleaned and draped, then numbed. The anesthetic sting is the part most people describe as the worst of it, and it lasts a few seconds.
  4. The incision. A few millimeters, made with a scalpel tip through numb skin.
  5. Placement. A trocar is passed through that opening into the subcutaneous fat and the pellets are laid in a fan, each in its own tract, several centimeters from the entry point rather than stacked together.
  6. Closure. Adhesive skin strips and a pressure dressing. Sutures are usually unnecessary for an opening this small.
  7. You go home. No sedation, no driver, no fasting.

The first week is the aftercare that counts

  • Keep the outer dressing dry and in place for 24 hours, then keep the adhesive strips on until they lift on their own.
  • No submersion for about a week. Showers are fine. Pools, hot tubs, the ocean and baths are not.
  • Go easy on lower body training, cycling and long runs for three to seven days.
  • Expect a bruise, tenderness when you press the site, and a firm area you can feel under the skin. All of that is normal.

That advice is not fussiness. In the published series, complications cluster in patients who returned to heavy activity early or received a larger number of pellets.

What can actually go wrong

Two problems account for most of it: the pellet works its way back out through the incision, and the site gets infected.

Reported rates vary enormously between clinics, which is itself the useful finding. A review of testosterone pellets in hypogonadism collects extrusion rates ranging from about 40 percent in one early series down to roughly 0.3 to 1.1 percent in later ones, with infection reported anywhere from 0.3 to 6.8 percent. Those are single-centre series and registry data, not randomised trials, so the honest reading is that technique, pellet count and aftercare drive the number far more than the pellet does. Repeated insertions also build palpable fibrosis at the site over the years, making later procedures harder.

The limitation nobody advertises

Once a pellet is in, the dose is fixed. It cannot be dialled down, and removal is genuinely difficult once the pellets begin to dissolve. Injections and creams can be stopped tomorrow. A pellet cannot. That is the honest tradeoff for not thinking about your hormones for three months, and it is why patient selection matters more here than with any other route. Our comparison of TRT injections versus pellets sets the two side by side.

Regulatory status deserves the same plainness. A testosterone pellet is FDA approved for men with documented hypogonadism. Compounded pellets are a different category. The Endocrine Society and ACOG both advise against routine use of compounded bioidentical hormones, and pellets are the formulation they name most often. There is no FDA approved testosterone product for women in the United States, so testosterone prescribed to a woman is off label wherever she is treated. A review of subcutaneous estradiol pellets reports supraphysiologic estradiol levels in roughly 3 percent of large cohorts, and one retrospective study in which mean peak levels reached about 238 pg/mL, well above the range usually considered appropriate. Women with a uterus who take estrogen in any form need endometrial protection, and pellets do not change that rule.

None of this makes pellets a bad option. It makes them one that requires a clinician who monitors levels, keeps doses conservative and is willing to say no. Our page on whether pellets are safe goes deeper into that evidence.

Call us, or go to urgent care

  • Spreading redness, warmth or a red streak moving away from the site
  • Fever, chills, or pus draining from the incision
  • The incision opening, or a pellet becoming visible or falling out
  • Bleeding that soaks through a dressing
  • Pain that is getting worse after day three rather than better
  • New or heavy vaginal bleeding after starting estrogen

What happens next

Follow up labs are usually drawn a few weeks after insertion so the next dose is corrected rather than guessed at. Most people need reinsertion between three and six months, and men often land closer to three to four. Symptom relief is not instant, which we cover in how long hormone therapy takes to work.

If you are weighing pellets against the other routes, have that conversation before the trocar, not after. Learn more about our hormone therapy services, in person in Deerfield Beach and by telehealth across Florida, in English, Portuguese and Spanish.
