- People with aromatase excess have increased production of aromatase, which converts androgens (like testosterone) into estrogen. People with XY chromosomes and aromatase excess syndrome will therefore have more active estrogen in their bodies than is typical. As a result, they will often stop growing at a shorter height and/or develop breasts in adolescence along with features associated with a typical testosterone puberty. People with XX chromosomes can also have aromatase excess, but it doesn't usually cause their sex characteristics to vary from what is considered typical for those assigned female at birth, though they may also experience breast enlargement and short stature, along with menstrual irregularities.
