krishna , I collected some information on HRT(thru internet source)
Hormone therapy (HT), also called hormone replacement therapy (HRT), for
transgender people involves taking estrogen and testosterone. Hormones are
produced by the endocrine system, which is made up of glands that release
chemical hormones into the bloodstream. Among other functions, hormones
control sex characteristics, like breast development, facial hair, and
reproductive systems. Both men and women produce these hormones, but
biologically, women produce more estrogen while men produce more
testosterone.
Effects
The feminizing effects of estrogen and the masculinizing effects of
testosterone may appear after the first couple of doses, though it may be
several years before a person is satisfactorily transitioned.
Male to Female Changes
Males transitioning to females (MTF) experience the following effects of
estrogen:
• Breast development (full development takes several years)
• Loss of ejaculation
• Loss of erection
• Shrinkage of testicles
• Sterility
Temporary changes, which are reversible after HRT(MTF) is stopped, include the
following:
• Decrease in acne
• Decrease in facial and body hair
• Decrease in muscle mass and strength
• Skin becomes softer and smoother
• Slowing of balding pattern
• Redistribution of fat from abdominal area to hips and buttocks.
