>> reporter: at age 13 natalie came out as transgender and asked to be called nathan. >> if someone were to wake up in the wrong body they'd be freaking out. >> reporter: he's now one of a growing number of brave transgender kids who are controversially transitioning, both socially and medically, all before adulthood. >> this is something i'm going forward with. >> reporter: when we met them four years ago they let our cameras document the transformal journey over several years. >> five years on testosterone will get a lot of the irreversible changes he wants. >> reporter: nathan's already experienced that ugly taste of violence, including a brutal beating to the genitals. >> a group of boys weren't sure if he was a boy or a girl. and they decided if they kicked him that they would be able to find out. >> people started thinking of me as the weird kid. the different one. i got taunted in the halls. >> reporter: he's now doing school online. but it's left him further depressed. >> now it just feels like i don't have anyone to talk to. >> reporter: in the last six months at least six transgender teens took their own lives, often because they felt unsupported by parents or peers. a staggering 41% of transgender youth will attempt suicide before age 25. >> it just becomes a panic. >> reporter: dr. melvin belser runs the largest transgender youth clinic in the country. >> the percentages that we have statistics on, how many were spat on, how many had to drop out of school, are horrendous. >> basically what i wear three layers of spandex. i want my boobs gone. >> reporter: he's started on drugs that have suspended his periods, essentially early menopause. >> going through your period is something hard for a girl. for a guy it's completely embarrassing. >> reporter: he's gearing up to start the male hormone testosterone under the care of an endocrinologist. >> the main thing that's going to happen is your ovaries are going to totally shut down they won't make estrogen anymore. >> reporter: the testosterone will masculinize his body. he'll develop body hair bigger muscles. over time his breasts will shrink. >> you can see critics saying don't mess with nature. what if he changes his mind? >> would you rather have a happy kid? or would you rather have a dead kid? >> to you, the answer's clear. >> right. >> reporter: in addition to hormones they're going to court to legally change his name. >> we'll grant this application for change of name. >> reporter: with those few simple words a monumental change. >> and that's it. >> thank you. >> thank you. >> blee! >> nathan is now officially our son. he doesn't have to have his female name any longer. >> it's just phenomenal. i'm going to remember this day as one of the greatest days of my life. >> i just want him to be happy. if this makes him happy, i'm very happy for him. >> reporter: back at home food friends, laughter, and of course cake. >> it says "it's a boy," then my name. my new name. >> reporter: tammy sending out a new birth announcement. >> i just say, help us in accepting and loving and welcoming our son as of this date she will no longer be she. >> reporter: and soon enough it's time for the first shot of testosterone. >> have that coursing through the veins is just -- what's going to be making him happy. >> reporter: tammy writes bro energy on nathan's rear to cheer him on. >> is it over? >> yeah that's it. >> reporter: make no mistake, there are controversial irreversible effects of testosterone, including potential infertility. >> we don't really know what the impact of these hormones are going to be. >> there is some truth to that matter, except in medicine we have to weigh the risks of doing nothing. >> reporter: to celebrate, nathan heads to the trans support group his mother helped him find. his buddies have made him testosterone-themed cupcakes. in three to six months he'll see physical effects. to keep them over time he'll have to take the hormones the rest of his life. >> where do you see yourself in a year? >> going into public school and people find out, they find out. >> reporter: a year later, he's come to san francisco for the next big step. his parents have made the boold decision to allow him, at age 16, to get a double mastectomy. what's known as top surgery. >> my parents were sort of thinking, oh well, you can have that when you're 18. and from there it sort of evolved over time to, yeah, okay, we need this now. >> reporter: dr. michael brownstein will perform that surgery. >> i felt quite comfortable that this was appropriate for nathan. and i think nathan is going to be quite pleased. >> you nervous? >> kind of. >> reporter: it's an expensive procedure. almost $10,000, not covered by insurance. the next morning, the surgery begins. hours later, nathan is in recovery. >> do you feel happy? >> i'm just tired. >> there's a whole bunch of bandages. >> reporter: will this complicated surgery so young be the right choice? a few months later, nathan's flat chest is healing nicely. >> it's been forever since i've been at a pool and felt comfortable being in a pool with my shirt off. it's just -- i can't even describe the feeling. >> it's amazing. we wanted him to be able to do things that kid dozen. and that's what he's doing now. >> reporter: this 16-year-old boy is driving as well. >> it says "male" on my driver's license. new name new gender, new everything. >> reporter: the next time we check in with nathan he's almost 18. >> i'm comfortable with me. >> reporter: a young adult. a self-confident young man. >> this is the way i've always wanted to look. and this is the way i've always imagined myself being. >> reporter: since transitioning he's returned to public school. and today, he's graduating. >> this is how i dreamed it would happen. i'm graduating as a boy. not as a girl like i was afraid of. i know if i had to live as a girl now, i would most likely be very depressed. hopefully not but i most likely would have tried to kill myself. >> did you ever think you would find this moment in time where you have this happy, well-adjusted son? >> if we didn't transition for sure he would be a very angry person. >> reporter: nathan says he's forever grateful for his parents' support. but he surprised us saying there was another voice in his head all along. the words of a second grade counselor named amy. >> she said to me there's other people like you and you're not alone. so i always thought that was the most profound piece of advice ever. and it kept me going from second grade on. >> reporter: he'd long ago lost contact. but we thought, what if we could find her? >> hi. >> look at you! oh my gosh. oh! you can't believe how long i've waited for this day. it's like a dream that i wished for. and to see it come true is -- >> exactly. >> reporter: it was a decade ago that nathan then natalie, first met amy. sent to her office after declaring "i'm a boy" in the strongest way he knew -- in those black crayon flyers he passed out in class. >> this is our "i'm a boy." "i'm not a girl." >> reporter: amy still has his file, the only file she kept in her 20-year career. >> i couldn't do anything big but i could be there every day when natalie needed to talk. >> just -- thank you. for everything. i don't want another kid to have to go through life thinking they're different or they're wrong. they need that one person that says, you're all right. that's what matters. just having one person. >> reporter: one person, or in nathan's case three caring adults, to make all the difference for one transgendered child. up next how former "real housewife" teresa guidice is putting a unique spin on her prison sentence. why family members say she's as glam as ever. and clearer skin. this is my body of proof that i can fight psoriatic arthritis from the inside out... with humira. humira works by targeting and helping to block a specific source of inflammation that contributes to both joint and skin symptoms. it's proven to help relieve pain, stop further joint damage and clear skin in many adults. doctors have been prescribing humira for nearly 10 years. >>humira can lower your ability to fight infections, including tuberculosis. serious, sometimes fatal infections and cancers including lymphoma have happened, as have blood, liver and nervous system problems, serious allergic reactions and new or worsening heart failure. before treatment, get tested for tb. tell your doctor if you've been to areas where certain fungal infections are common, and if you've had tb, hepatitis b, are prone to infections, or have flu-like symptoms or sores. don't start humira if you have an infection. >>visit humira.com and talk to your rheumatologist. humira. this is a body of proof! curling up in bed with a ... ...favorite book is nice. but i think women would rather curl up with their favorite man. but here's the thing: about half of men over 40 have some degree of erectile dysfunction. well, viagra helps guys with ed get and keep an erection. and remember, you only take it when you need it. ask your doctor if your heart is healthy enough for sex. do not take viagra if you take nitrates for chest pain; it may cause an unsafe drop in blood pressure side effects include headache, flushing, upset stomach and abnormal vision. to avoid long-term injury, seek immediate medical help for an erection lasting more than four hours. stop taking viagra and call your doctor right away if you experience a sudden decrease or loss in vision or hearing. ask your doctor about viagra. ♪ ♪ ♪ turn around ♪ ♪ every now and then i get a little bit hungry ♪ ♪ and there's nothing good for me around ♪ ♪ turn around ♪ ♪ every now and then i get a little bit tired ♪ ♪ of craving something that i can't have ♪ ♪ turn around, barbara ♪ ♪ forever i've been praying for a snack in my life ♪ ♪ and now i have a brownie ending all of my strife ♪ ♪ i finally found the right snack ♪ ♪ ♪ you know, it really seemed as though real housewife teresa guidice's life blew up when she was sentenced to 15 months behind bars. she'd have to leave her family behind not to mention all that bling. trading in her mansion for a prison cell. tonight it turns out she's adopted a new look. and she's somehow making it work. has anyone done time like this before?
