Recently, I spoke with a woman who was looking for a new hormone-savvy provider. As we began talking, I couldn’t help but notice her voice—low, gravelly, with a sort of sexy smoker’s rasp. But as she shared more of her hormone history, I began to suspect there was something else going on: unintentional vocal deepening, likely due to testosterone pellets.
If you’ve never heard of hormone pellets, here’s a quick primer: pellets are small, compounded hormone formulations—typically containing estradiol and/or testosterone—that are inserted under the skin, most commonly in the upper buttocks area. This is a minor surgical procedure performed every three to four months. Once implanted, the pellets slowly release hormones into the bloodstream over time.
Sounds convenient, right? But here’s the catch: these pellets deliver fixed doses of hormones, which makes them hard to fine-tune. And because many pellet regimens include very high doses of testosterone, it’s not uncommon for women to end up with supratherapeutic (too high) hormone levels. While this can make some women feel amazing at first—think increased energy, higher libido, and sharper mental clarity—it often comes at a cost.
Too much testosterone can cause a range of unwanted and sometimes irreversible side effects. These may include:
- Acne
- Scalp hair thinning
- Increased facial or body hair in unwanted areas
- Mood swings or irritability
- Clitoral enlargement
- Permanent vocal deepening
And while some of these symptoms might subside once the testosterone clears your system, others—like voice changes—are not reversible.
Another issue? Once a pellet is in, you can’t “un-dose” it. You’re committed to that hormone level until the pellet wears off, which can take months. That lack of flexibility is a major red flag for me as a provider. In functional and precision medicine, I’m always aiming to personalize hormone therapy based on a woman’s unique physiology, symptoms, and lab data. Pellets don’t allow for that nuanced approach.
And here’s something many women don’t find out until they try to switch off pellets: it can be really difficult to transition to other forms of hormone therapy afterward. After months—or even years—of being on high, unregulated doses, it takes time for the body to recalibrate. Lower, safer doses of hormones often feel underwhelming in comparison, and the process of adjusting can be frustrating and emotionally taxing.
There are safer, more adjustable methods for hormone therapy—like transdermal creams, patches, and sublingual lozenges—that allow for careful titration, ongoing monitoring, and shared decision-making over time.
In my practice, I want women to feel great and stay safe. Hormone therapy should support long-term vitality, not introduce unnecessary risks or make future care more complicated.
So when it comes to pellets? It’s a pass from me.
