good evening. tonight we're going inside a conception controversy that's got mothers and families pitted against each other. for many couples surrogacy can be their path to parenthood. but it can cost tens of thousands of dollars. a big business that some are now saying is wrong and maybe even downright dangerous. here's abc's linsey janis. >> why can't you tell me how much money you were paid? >> this woman, jennifer lull-s on a mission to put an end to surrogacy. >> empowered women -- empowered women can say -- >> empowered women can make their own choices. >> reporter: tracy bullard is standing up for surrogate mothers everywhere. >> i take the position we shouldn't be doing this. >> reporter: jennifer lull is here in minneapolis screening

her latest documentary, "breeders: a subclass of women," in which she argues that the surrogacy industry needs to be stopped. >> women are not breeders. children are not products and commodities. you know, women are not easy-bake ovens baking cupcakes for other people. >> reporter: her documentary features women who have deep regrets about becoming surrogates. >> the first time they picked up the baby and brought him over to my side and just held him up. i've never seen or heard from him since. i think about him every day. >> reporter: lahl is a mother of three, a former neonatal nurse, the president of the conservative-leaning center for bioethics and culture, and she holds a master's in bioethics from a well-known evangelical university. >> some of your critics say that your views are based on your religious beliefs. >> yeah. because that's an easy card to play. because then the people say, you know, she's this, she's that. but i tell people all the time,

i'm against surrogacy. i don't care if you're gay, straight, single. >> reporter: lahl accuses the multibillion-dollar global industry of concealing the health risks for prospective surrogates and equates it to selling organs. >> if you want to be a kidney donor, we say that's wonderful. but you are not allowed to be paid. we say no. because what happens when commerce enters in is people will make decisions that are not in their best interests for their health. >> reporter: lahl's anti-surrogacy position is quite controversial, especially since children born through gestational surrogacy is on the rise. in fact, surrogacy has had some high-profile attention, from nicole kidman to sarah jessica parker and ricky martin. all using the method to expand their families. >> a couple spend their entire lives wanting a child and not being able to have one just kind of resonated with me. >> reporter: tanya prashad, a one-time surrogate mother, supports lahl's argument. back in 2003 she was the

surrogate for a same-sex couple using her own egg and regretted it instantly. >> and then when she was right there in my arms all those little pieces of paper that we signed just kind of fell away. i never thought about her. i never for a second thought about what was right for her and what she deserved. >> did you feel guilty? >> horrible guilt. and shame. both. an even mix of both. >> you felt like someone who'd given their child away. >> i felt like someone that sold my child. >> reporter: even though she signed away herr legal rights, tanya worked out a deal with the child's parents that she'd still be involved. >> what was your understanding of the agreement? >> that i would have a baby and she'd live with them but i'd always be a part of her life. there's not another mom. so i would -- the plan was for me to still act in the capacity as her mom. >> reporter: but she says that's not what ended up happening and over the years tanya fought to

keep a relationship with the daughter she gave birth to. >> so then we ended up in court and we actually agreed on a joint custody order together. >> reporter: but lahl believes it's not just the mothers. she says the newborns suffer too. >> the fracture of that bond can have significant damage. short-term and long-term. >> is there any actual evidence that it's harmful to the child? >> there's a study that just came out last year, and that study actually showed that these children around the age of 7 had some behavioral, some developmental problems. these are people's lives that are being formed now and we're going to ask to study it after the fact? shouldn't we stop and really look at what we're doing and say what is in the best interest of children? >> reporter: that study she's referring to is by researchers at cambridge university and it showed higher levels of psychological problems for surrogate children at age 7 then the comparison group of naturally conceived children. however, those children showed above average psychological

well-being. and the study showed differences disappeared by age 10. >> i think we have to be careful in interpreting this data and laterally not throw the baby out with the bathwater so to speak. >> reporter: dr. jen ashtoton ss wee really just beginning to understand the impact of surrogacy. >> i think the people who have concerned about it really need to reserve judgment till a lot more long-term data is known. >> reporter: but tanya believes her 10-year-old daughter is still overcoming issues stemming from being born this way. >> she's got a lot of insecurities and a lot of fear. she needs a lot more reassurance. she needs that extra pat, that extra hug, that extra everything's going to be okay. >> reporter: that cambridge study also tells us that there are likely raised levels of psychological problems for surrogate children at age 7 because that's when they gain a better understanding of how they were born. and they have questions. >> i'm a product of a traditional surrogacy. >> reporter: like jessica kern,

who says she spent her entire childhood in the dark, wondering why she looked so different from the woman who was raising her. eventually discovering her biological mother was the surrogate and went about tracking her down. >> i know exactly how much she earned for delivering me. >> how much was it? >> $10,000. >> you believe she was motivated by money. >> you can't say that's not motivating. >> i think one of the most important things for people to remember when they talk about unconventional ways to become parents today is a lot more goes into being a parent than biology. it's very important to remember that. because people can get very, very emotional when they talk about these types of issues. the medical ones are straightforward. the social ones get a little trickier. >> empowered women can say -- >> empowered women can make their own choices. >> reporter: but even with all the evidence lahl cites, she's still got her critics. >> why can't you tell us how much money you were paid?

>> are you not sympathetic to couples who are infertile or to same-sex couples that cannot have their own biological children? >> i'm incredibly sympathetic. but just because somebody can't have a child doesn't mean that i have to say by all means, any way you can get the child is fine. there's a long step between i can't have a child and what are the ethical ways to fulfilling that need to getting a child? >> reporter: for "nightline" i'm linzie janis in minneapolis, minnesota. next, she's got a new single and a new sound. wi what taylor swift has to say about her musical rebirth with "shake it off." avo: get a $1,000 turbocharged reward card on new 2014 turbo models or lease a 2014 passat s for $189 a month after a $1,000 bonus.

once upon a time a 14-year-old girl from pennsylvania moved to nashville to pursue a career in country music. seven grammy awards later, taylor swift is officially

changing her tune. so what does the future sound like for a country crooner gone rogue? here's abc's amy robach. ♪ ♪ got nothing in my brain [ cheers and applause ] >> to announce her latest news, taylor swift took to the digital sphere. streaming into homes around the world. >> we have people from brazil to canada to norway. i have a song i'm going to play new like 30 seconds. ♪ ♪ and the haters gonna hate, hate, hate, hate ♪ ♪ i'm just trying to shake, shake, shake ♪

♪ shake it off ♪ shake it off >> who were you telling to and what's your message in the song? >> the message in the song is a problem i think we all deal with and an issue we deal with on a daily basis, that we don't live just in a celebrity takedown culture. we live in a takedown culture. people will find anything about you and twist it to where it's weird or wrong or annoying or strange or bad. and i think that for me writing this song was partly about my life but it's mostly about the things that i hear from my fans in these comments on instagram and facebook and twitter and things like that. they're dealing with the same things i'm dealing with. their bullies are posting things about them that aren't true on facebook, whereas mine are sort of like in the grocery aisle like when i'm checking out. but i think that you have to -- you have to not only live your life in spite of people who don't understand you, you have

to have more fun than they do. >> i like that. that's a great way to look at it. >> reporter: the reason behind the catchy album title? >> i was born in 1989, and for me this is sort of a almost musical rebirth in that it's my first pop album. it's a big change. and it's a change that i'm really excited about. so i decided to name thisfter my birth year. >> reporter: swift's career has evolved from the early days as a country star singing about teardrops on her guitar. ♪ here's the reason for the teardrops on my guitar ♪ >> to more mainstream hits like "you belong with me." ♪ you belong with me ♪ you belong with me >> reporter: but this album fans will see a whole other side of taylor. ♪ shake it off ♪ shake it off and you say this is your first pop album. why did you go pop? you were more country. you went a little bit country. now you're a little bit pop. not a little bit rock and roll.

or a little bit both. >> i feel like for the last two years there's been sort of a sonic evolution happening and i've been experimenting more and more. and i think you have to follow just this intuition, this gut feeling as a songwriter, you just want to write a certain kind of music and you don't know why. and you can either challenge that or you can go with it. so i just did what felt naturally to me. the only choice we have in life is to change. >> reporter: in addition to embracing change, swift is not afraid to let her fans see her with her hair down. often posting candids on social media, reaching nearly 50 million fans. >> we all see how important girlfriends are to you. and you love to post pictures on instagram, social media. and you're with people who are also in successful creative endeavors. how do you choose your friends? >> i choose my friends based on people who i have things in common with or people who challenge me. honestly, i think that there's something really inspiring about being around people who know what they want, people who are

passionate about something. i think that it doesn't matter what career my friends have. it's just based on the fact that i can really relate to people who are very driven and intelligent. you want to be around like smart, exciting people. i think that just -- that brings you up. >> reporter: in an editorial in the "wall street journal" last month swift wrote, "i think forming a bond with fans in the future will come in the form of constantly providing them with the element of surprise." ♪ my ex-man brought his new girlfriend ♪ >> which xlnexplains why you se very different taylor in "shake it off." >> you like to surprise, not necessarily shock. >> yes. that's something i talk a lot about too. get out of my head. stop it. i do talk about this a lot because i think the element of surprise is what we want. it's what we long for. we want to be surprised. and i think that shock is a different thing. i think with the element of surprise you keep trust intact

and i think with the element of shock you run the risk of your fans who thought they knew you sit there -- they sit there and go, well, what is -- what? like but i thought i knew her. so to me that is not big priority. shock is not a big priority. i really want to keep evolving sonically and keep growing up year by year, one year at a time. i'm 24 now. >> i love that. you talked about the ever-increasing interest in the private lives of musicians, you that don't think that's ever going to go away. that's the one thing that may actually get worse. does writing songs about your life help you in a way confront that? >> people are curious. the element of human curiosity is never going to go away. i just try really hard to have the right outlook on it. as far as the career that i've chosen, i've been very honest about the fact that i entrust my fans and also the rest of the world who don't understand with the insight into what i'm

actually going through. and somehow to me having the people who get me, really get me, makes it easier to take when other people don't because i don't really care about them because i have you.

a girl with a fearsome arm

has just made sports history by pitching a shutout in the little league world series. and did i mention she got a hit, too? now 13-year-old mo'ne davis is gracing the cover of "sports illustrated." but get this. she's not ready to just settle for baseball either. here's abc's john donvan. >> reporter: there used to be a putdown you heard a lot more in the old days. "throws like a girl." well, mo'ne davis is a girl. and, um, well -- >> first strikeout of the game. >> reporter: she throws pretty good. pitches clocked at 70 miles an hour. major league pitchers throw upwards of 90 miles per hour. and helping her team the philadelphia tannee dragons into the little league world series where she's become the first girl to throw a shutout in world series history. >> it's over. a complete game for mo'ne davis. >> reporter: allowing just two hits and striking out eight boys.

she hits, too. a run-scoring single in her most recent game. >> he's going to score. mo'ne to second. >> reporter: which is not all about her, of course. she is the first to say that. >> i don't really like all the attention because this year like everything's about me and they don't see the whole picture of my teammates. and without my teammates i don't think we'd be here right now. >> reporter: attention? how about the cover of "sports illustrated" this week? the first little leaguer ever, boy or girl. yeah, that counts as some attention. and she says that she saw her twitter account jump from 2,000 to 15,000 followers in just a couple of days. all of this catching her by surprise because she's only in the eighth grade. >> i never thought that i'd be a role model at this age. so it was kind of shocking to me when i first came down to watch a game, there was like a crowd of people. i was like kind of nervous, but then i was like excited for it. so i just have to just be myself. >> reporter: she's been playing baseball since she was 7, along

with a lot of other sports. >> i was playing football, and i was tackling the boys and i was throwing spirals. that's when the coach came up to me and he was like you have to play baseball. i was an outfielder and then i started pitching at 8 or 9 and i wasn't the best but i threw strikes. then my arm started getting stronger and stronger. so i started throwing gas. like my fastball started speeding up. >> reporter: she's known for keeping cool out there, which makes her kind of a team leader, one who is already thinking about college way down the road. uconn maybe to play basketball. different game. so if you want to watch her throw? gas, better get out and watch her throw now. >> another strikeout. >> reporter: for "nightline" i'm john donvan in washington. >> go, mo'ne. you can catch mo'ne in the little league world series tomorrow night on our partner network, espn. thanks for watching abc news.
