Male levels of testosterone directly induce growth of the testicles and penis, and indirectly (via dihydrotestosterone (DHT)) the prostate. Estradiol and other hormones cause breasts to develop in females. However, fetal or neonatal androgens may modulate later breast development by reducing the capacity of breast tissue to respond to later estrogen.
In males, testosterone directly increases size and mass of muscles, vocal cords, and bones, deepening the voice, and changing the shape of the face and skeleton. Converted into DHT in the skin, it accelerates growth of androgen-responsive facial and body hair, but may slow and eventually stop the growth of head hair. Taller stature is largely a result of later puberty and slower epiphyseal fusion.
In humans, secondary sex characteristics include:
* Male
- Growth of body hair, including underarm, abdominal, chest, and pubic hair
- Greater mass of thigh muscles in front of the femur, rather than behind it as is typical in mature females
- Growth of facial hair
- Enlargement of larynx and deepening of voice
- Increased stature; adult males taller than adult females, on average
- Heavier skull and bone structure
- Increased muscle mass and strength
- Broadening of shoulders and chest; shoulders wider than hips
- Increased secretions of oil and sweat glands, often causing acne and body odor
- Coarsening or rigidity of skin texture, due to less subcutaneous fat
- A prominent Adam's apple
- Fat deposits mainly around the abdomen and waist
- Higher waist to hip ratio than prepubescent or adult females or prepubescent males, on average
- On average, larger hands and feet than prepubescent or adult females or prepubescent males[citation needed]
- Lower digit ratio, on average
So basically, it sounds like you have high DHT levels which occurs a lot of teenagers. This leads to the over-production of sebum etc. leading to acne. If you are susceptible to Androgentic Alopecia (Male pattern Baldness) you might notice an increase in hair loss due to the androgen "DHT" binding to the androgen receptors in the hair follicle. This will lead to miniaturization of the follicle and eventually it will dissapear. Now I would think with what little information you are telling us, that you probably are prematurely suffering Male Pattern Baldness like myself, but it's impossible to tell without seeing pictures.
Even if you do show pictures you most likely are in the very early stages of male pattern baldness and therefore it would be very hard to tell that you are suffering male pattern baldness. Also, most members on this forum demand you to be a least a NW2.5 before they expect that you might be suffering male pattern baldness, I don't know why but that's just the way it is. I reccomend visting a proffesional or your local GP (most don't have a clue). Try and get him to arrange a meeting with a Dermatologist.
Don't worry yet, it could be for a number of reasons, I'm just stating the most common cause.
