What is FTM Bottom Growth?
One of the most common questions FTM individuals ask is: What happens with bottom growth on testosterone? This comprehensive guide covers everything you need to know—from timeline and expectations to enhancement options and managing discomfort.
3-6 months
When changes start
1-5 cm
Typical growth range
1-2 years
Maximum growth period
Bottom growth is possible with testosterone hormone replacement therapy (HRT), but the extent varies significantly from person to person. This is often one of the first physical changes when a transmasculine person begins testosterone therapy.
Bottom growth can be defined as increased clitoris size, with its shape gradually resembling a small penis. Clitoral growth is a direct result of testosterone therapy, and the clitoris and penis develop from the same embryonic tissue, which is why testosterone causes this masculinizing effect.
FTM bottom growth refers to the significant increase in clitoris size that many transmasculine individuals experience as a result of testosterone therapy, a key component of gender-affirming hormone therapy. This process is medically known as clitoral hypertrophy.
For those undergoing hormone therapy, understanding the science behind FTM bottom growth, its typical timeline, and the factors that influence it—such as genetics, testosterone dose, and individual hormone levels—can help set realistic expectations.
Remember, everyone's journey is unique, and individual experiences with bottom growth and bodily changes can vary widely.
Timeline & Expectations
You can expect bottom growth to typically begin within the first 3-6 months of starting testosterone, with the most noticeable changes occurring between 6-12 months. Maximum growth is usually achieved within 1-2 years.

What Does It Feel Like?
During initial stages, the genital area typically becomes more sensitive. This can include irritation, swelling, itching, and soreness. These symptoms are usually temporary but can be intense for some.
Sensations tend to be most intense during the first six months, according to research in the Journal of Sexual Medicine.
Managing Discomfort
🧴 Moisturize
Use gentle, fragrance-free products to soothe skin and reduce dryness. Avoid harsh soaps.
👕 Soft Fabrics
Wear breathable cotton underwear to minimize irritation.
🩲 Loose Fit
Boxers reduce friction and pressure on sensitive areas.
💊 Pain Relief
OTC anti-inflammatory meds may help during adjustment periods.
Emotional & Physical Impact
Bottom growth can be emotionally affirming, bringing the body more in line with gender identity. This can significantly reduce dysphoria and lead to feelings of euphoria.
- Reduced gender dysphoria
- Increased body confidence
- Enhanced sexual pleasure for many
- Greater alignment with identity
However, experiences vary. Some may feel frustration if growth doesn't meet expectations. A Journal of Sexual Medicine study explored how testosterone affects tissue growth and sensitivity.
Body Image and FTM Bottom Growth
The physical changes brought on by bottom growth can have a profound impact on body image and self-esteem for FTM individuals. For many, seeing their body align more closely with their gender identity brings a sense of gender euphoria and increased confidence.
However, everyone's journey is unique, and some may find it challenging to adjust to these new aspects of their body. Open conversations about body image, sexual function, and the emotional effects of bottom growth—with healthcare providers, supportive friends and family, or within the trans community—can be invaluable.
Everyone's journey is different. What matters most is how YOU feel about your body. Embracing these changes at your own pace and seeking support when needed can help foster a positive relationship with your body.
Enhancing Bottom Growth
If you want to maximize growth during testosterone therapy, there are several approaches:
🔵 Clitoral Pumping
- Uses suction to increase blood flow
- Temporarily increases size and sensitivity
- Regular use may lead to sustained growth
- More effective after starting T
- Start with short sessions
💧 DHT Creams
Topical treatments such as DHT cream and dihydrotestosterone cream can be applied directly to the genital area to promote bottom growth. These creams are sometimes used as alternatives to other hormone therapies, but should only be used under medical supervision to ensure safety and effectiveness.
- Binds to receptors more effectively
- May cause side effects (hair changes)
- Consult healthcare provider first
🔧 Surgical Options
For those seeking more significant changes, bottom surgery—which includes procedures like metoidioplasty and phalloplasty for gender affirmation—offers permanent surgical solutions.
Minimizing Growth
Not everyone desires bottom growth. Options to minimize this effect:
📉 Lower Dosage
Reducing T dose can slow or limit growth. Discuss with your provider.
💊 DHT Blockers
Finasteride or dutasteride prevent T from converting to DHT.
These options may have side effects like return of menstruation or reduced hair growth. Discuss with your healthcare provider to find the right balance.
Consider FTM prosthetics as an alternative to hormone-induced changes.
Sexual Changes
🔥 Increased Libido
Many experience heightened sex drive on testosterone.
✨ New Sensations
Increased size and sensitivity lead to different pleasures.
🔄 Changed Arousal
Arousal patterns may shift significantly.
💧 Vaginal Changes
Some experience dryness—lubricants help with comfort.
Clitoral Hood Changes
During testosterone therapy, the clitoral hood—the fold of skin that covers and protects the clitoris—can also undergo changes alongside bottom growth. As the clitoris increases in size, the hood may become less prominent, shift in shape, or stretch to accommodate the new dimensions.
These changes are highly individual; some people notice a significant alteration in the appearance of their genital area, while others see only subtle differences.
Bottom growth may introduce new sexual possibilities. Open communication with partners and taking time to explore at your own pace fosters positive experiences.
Side Effects
🩺 Monitoring Levels
Regular blood tests are important to ensure safe hormone levels and avoid side effects.
💧 Vaginal Health
Atrophy and dryness possible. Estrogen suppositories or lubricants may help.
Regular check-ups and open communication are essential. Your provider can help manage side effects and adjust treatment as needed.
Reversibility
Genital changes from testosterone are generally considered permanent. Once growth occurs, it's unlikely to fully revert even if testosterone is stopped.
- Bottom growth is typically irreversible
- Some report partial reduction after stopping T
- Extent of reversal varies widely
- Discuss concerns with provider before starting
A frequent question for those considering or undergoing testosterone therapy is whether bottom growth is reversible if hormone therapy is stopped. In most cases, bottom growth is considered typically irreversible—meaning that once the clitoris has grown in response to testosterone, it is unlikely to return to its original size, even if testosterone therapy is discontinued.
However, there are anecdotal reports of some reduction in size, particularly if testosterone was used for a short period or started at a younger age. The degree of reversibility can depend on factors such as the duration and dose of testosterone therapy, individual genetic factors, and the timing of when hormone therapy began.
