Breast development continues, testicles have atrophied significantly and erection is extremely difficult. Maximum breast development is reached at around 2 years, by which time the individual appears female aside from the genitalia. The skin texture takes on a rougher appearance and acne is likely to occur. Muscle mass increases, as does the libido, and the menstrual cycle may be interrupted. By six months the skin texture has changed and muscle mass is still increasing.
Clitoral elongation is noticeable.
By one year the voice is lower, facial hair is present, even beard growth and male pattern hair loss may occur. The individual may grow in height and shoe size and the clitoris continues to grow and may be 2-3 inches long at this point. Menstruation has probably ceased and there may be weight gain. Missing hormones for a few days will have little effect, possibly mood swings, but stopping for a significant period of time will result in general reversal. Certain effects of hormones cannot be reversed, these include breast growth and sterility after oestrogen in male to female, and facial hair growth, male pattern baldness and changes in voice after androgen in female to male.
