While the systemic effects of testosterone are both expected and desired in both trans men and female body builders, they are generally undesirable for most women. Thus, one of the most pressing questions is whether the clitoris can be enlarged without causing other unwanted virilizing effects. To reduce side effects, many women attempt local topical administration. Anecdotal evidence suggests that DHT ( Dihydrotestosterone ), a very potent androgen, can effectively be used for this purpose with minimal side effects. No scientific studies have confirmed this effect in female anatomy, but research targeting the treatment of micropenis has found that local application of DHT is very effective at stimulating penile growth in microphalli.  Due to the biological similarity between penile and clitoral tissue, significant growth of the clitoris is likely. Unlike testosterone, DHT can not be converted into the estrogen estradiol and is thus ideal for generating purely androgenic effects. Topical administration of DHT is a well known treatment for clitoral growth in the trans male community.
