An enlarged clitoris, called clitoromegaly, is one that’s noticeably larger than the typical range of about 3/4 inch to 1 inch in diameter at the glans (the visible, external part). In mild cases, it may simply look like a slightly more prominent nub of tissue peeking beyond the clitoral hood. In more significant cases, the clitoris can protrude well past the labia majora and resemble a small penis, particularly during arousal.
Typical Size vs. Enlarged
The visible portion of the clitoris, the glans, sits just above the urethral opening and is protected by a fold of skin called the clitoral hood. In most people, it’s a small, rounded structure. The clinical threshold for clitoromegaly in newborns is a clitoral length above 10 millimeters, while some clinicians define it as the clitoris extending 5 millimeters or more beyond the labia majora. In adults, the glans typically measures under an inch across. Clitoral size does increase slightly with normal growth and puberty, so modest variation is expected and healthy.
What separates normal variation from clitoromegaly isn’t a single number but rather a combination of size, how much the clitoris protrudes, and whether other signs of excess androgen (the group of hormones responsible for traits like body hair and muscle mass) are present. Clitoral enlargement is considered one of the most sensitive physical markers of increased androgen production.
What It Looks Like at Different Degrees
Doctors use a classification system called the Prader scale to describe degrees of genital virilization, most often in newborns with congenital adrenal hyperplasia (CAH). Understanding the scale gives a clearer picture of what enlargement can look like across a spectrum:
- Mild (Stage 1): A slightly enlarged clitoris with a somewhat reduced vaginal opening. This is often within normal variations and may not be immediately obvious.
- Moderate (Stage 2): The enlargement is clearly visible. The clitoris is intermediate in size, noticeably larger than typical, with the labia beginning to fuse toward the back.
- Significant (Stage 3): The clitoris is further enlarged and more prominent, with the labia nearly completely fused and a single opening where the urethra and vagina share a channel.
- Severe (Stages 4–5): The clitoris closely resembles a penis in size and shape. At the most extreme end, the external appearance can look fully male, with what appears to be a scrotum (though it contains no testes). Internal reproductive organs, including ovaries and a uterus, are present and normal.
Most people searching this topic are wondering about mild to moderate enlargement. In those cases, you’d notice a glans that looks puffier or longer than usual, sits higher or more forward, and may not be fully covered by the clitoral hood. During arousal, the difference becomes more pronounced because the clitoris engorges with blood just like a penis does.
Why It Happens
The most common driver of clitoral enlargement is excess androgens. This can come from several sources.
Congenital Adrenal Hyperplasia
CAH is a genetic condition present from birth. A missing enzyme prevents the adrenal glands from making cortisol properly, which throws hormone production off balance and floods the body with androgens. In female infants, the result is genital anatomy that looks different from typical: the clitoris may be enlarged enough to resemble a small penis, and the labia may be partially fused. CAH is the most common congenital cause of clitoromegaly and is usually identified at birth or shortly after through newborn screening.
Androgen-Producing Tumors
In adults, a clitoris that enlarges rapidly, over weeks or months rather than years, raises concern about a tumor on the ovary or adrenal gland that’s producing excess androgens. This type of enlargement typically comes alongside other changes like a deepening voice, new facial hair growth, or thinning hair on the scalp. The rapid onset is a key distinguishing feature. PCOS (polycystic ovary syndrome) involves elevated androgens too, but it rarely causes clitoromegaly on its own. When significant virilization like clitoral enlargement appears alongside PCOS-like symptoms, the priority is ruling out a tumor.
Anabolic Steroids and Testosterone
Anabolic steroid use is a well-documented cause of clitoral enlargement. These drugs are synthetic versions of testosterone, and prolonged use delivers a sustained androgen load the body isn’t accustomed to. The clitoris responds by growing, sometimes substantially. Unlike many other steroid side effects, clitoral enlargement often does not reverse after stopping the drugs. The same applies to testosterone therapy: people taking testosterone as part of gender-affirming care or for other medical reasons commonly experience some degree of clitoral growth, which is an expected and permanent effect of the hormone.
Physical Sensations That May Come With It
The clitoral glans is packed with nerve endings, making it the most sensitive structure in the vulva. When the clitoris enlarges, that increased surface area can change how everyday activities feel. Some people notice heightened sensitivity during normal movement, friction from clothing, or discomfort while sitting or exercising. Others experience increased sexual sensitivity that may or may not be welcome. The clitoral hood, which normally covers and protects the glans, may no longer provide full coverage, leaving the tissue more exposed to stimulation and irritation.
Treatment Options
Whether clitoromegaly needs treatment depends entirely on what’s causing it and whether it’s causing physical discomfort or emotional distress. If an underlying hormonal condition is identified, addressing the hormone imbalance can prevent further growth, though existing enlargement doesn’t always shrink back.
For people who want to reduce the size of a protruding clitoris, a surgical procedure called clitoropexy (sometimes called clitoroplasty) can reduce how far the clitoris extends. Modern techniques aim to preserve the nerve-rich tissue so that sensation isn’t lost. This surgery is most commonly performed on infants with CAH, though the timing and ethics of early surgery are actively debated among medical professionals and advocacy groups. Adults who pursue the procedure typically do so because of physical discomfort or significant self-consciousness.
For enlargement caused by anabolic steroids, stopping the drugs is the first step, though as noted, the growth may be permanent. In cases linked to a tumor, removing the tumor resolves the androgen excess and prevents further changes.
