And now try move free night. The first and only 2in1 the term family ties gets a little ambiguous when you think of children conceived through a sperm donor. Especially when there could be hundreds of them. Mark strassman has the story. Reporter what are your thoughts going into this, nervous . Definitely a little nervous, yeah. Reporter Todd Whitehurst is walking into the unknown. Swhaz if they turn out to be strange and shy and they dont look up and theyre verienty social. Reporter four kids are waiting for him, half mile away. I dont know what to do. Reporter one of them is 20yearold sarah mally. What makes you nervous . What do you say when youre meeting your biological family for the first time . I dont know. Reporter Todd Whitehurst is their biological father, the one theyre about to meet. Hes a 49yearold computer in 1998, then a stanford grad student, he noticed something in the school paper. They were running big ads, young men 18 to 30 needed for sperm donation. Reporter did you have any qualms about snit i guess my feeling on it was, the folks who end up going to a sperm bank really want children quite badly, and why wouldnt you want to help those people out . Reporter whitehurst, who has two children of his own from a previous marriage, never expected to meet any of his donor children. Sperm banks follow a protocol. All donor dads sign an agreement to remain anonymous. The families on the sefg end are only given basic Background Information about their donor. His edge, ethnicity, height, birthplace, education, so on. Clinics give each donor dad a unique donor i. D. Number, and thats become the gateway to whitehurst is about to have. And it they have would have happened if not for one woman. Its an innate human desire to want to know where we come from. Reporter wendy cramer is the mother of a donor son. She saw how curious he was to learn more about his donor father and founded an online database, a networking site. 47,000 people have registered, including 2300 donor dads. Kids want to know, i want to hear my donors laugh. I want to see him smile. I want to know what he thinks is funny. I want to, you know, i want to look into his face. I want to shake his hand. Reporter Carrie Phelps felt that way. Ive always known i was a donor child since i was 2. Reporter phelps, the daughter of a single mother, was father. Phelps had Little Information about him, but spent two weeks plugging what she did know into an online search. She found seven possible matches. One photo stood out. From that moment, when i saw his face for the first time, it was just incredible. Reporter her donor dad was Todd Whitehurst. She emailed him, they meat, became closer and even took vacations together with some of his other donor children. Like this trip to cape cod last july. I feel that its just the right thing to do. If the children want to meet, then its important, i think, to be available to meet. Reporter get ready to watch an extraordinary family moment. You must be keegan. Yes reporter eight donor children came together. Four of whom whitehurst had never met before, who are also yeah, it gets complicated. Look how strong you are. Youre like an ox. What is this moment like for each of you . Its pretty awesome. Reporter sar a mally, a student at bostons emerson college, learned that she and her twin sister, jenna, were donor babies. She contacted whitehurst through the registry and he helped arrange this family gathering. What was it like when you first walked out . Overwhelming. I was worried it would like a hello, its nice to meet you, like we hugged and that was the whole big thing. Reporter just sitting here, did you feel fathers pride . Oh, absolutely. When i hear her talking about the hug, i want to give her a hug again. Yeah, shes wonderful. Reporter the reproductive industry does little to make it nobody keeps track of the donors or kids. Reporter wendy cramer says sperm banks ask mothers to report donor births but it is not rird. And no Organization Links different clinics to track the total number of births from a single donor i. D. How many potential kids are out there from a single donor . Nobody really knows. The Largest Group that we have on our website, we know of a group that is somewhere around 200. Reporter 200 kids . Right. I dont know about you, but if i knew that i was i had 200 half brothers and sisters, i would feel like i was part of a herd. It would feel odd. Reporter whitehurst donated to the same clinic for four years. How many times would you guess, ballpark . Probably on the order of 400 times, Something Like that. Reporter 400 times . Yeah. Reporter and consider sperm bank can produce as many as 24 sellable viles. His 400 donations could have produced 9600 vials for the clinic to sell. How many donor children do you know that you have . I have 22, that i know of. Reporter you could have a family touch Football Game and have enough players for both sides. Does that seem a little crazy . It does seem crazy, yeah. Theyve all turned out to be quite remarkable children. Reporter Carrie Phelps now studies Computer Science at stanford, just like her donor dad. I never felt like there was something missing, because ive been so lucky. Im so wanted. And thats something that i think a lot of kids cant say for certain. So being able to meet all of the same time very related siblings is such abn incredible honor for me to grow up this way. The cbs overnight news will be right back. And pilled cardigans become pets.

They know who allhe super heroes are, yet they dont know the history. I think it will give them ideas. I hope it will in terms of creating some of their own comic books or art. Reporter that inspiration comes from seeing the Humble Beginnings of extraordinary characters. And the men who created them. We have batman, number one. Reporter for example, batmans solo debut in this may 1939 issue. Or superman in action comics number one. Original sketches. The 1938 royal typewriter made of steel that gave birth to the man of steel. And the wool and cotton costume worn by actor George Reeves in the 1950s Television Show the adventures of superman.

They were often discriminated upon because they were the sons of immigrants, most all of them the sons of jewish immigrants.

We also know that oil is trading at around 30 a barrel, another sign, perhaps, of global weakness. And finally, were starting up with earnings season, and theres a real concern that this is going to be a bad Quarterly Earnings season. A lot of companies, pretty sluggish by the end of t t year. Part of the reason is, they had to hire more eloyees and that took a bite out of their profitability. So, tell us, when is this going to stop . Reporter i wish i knew, but heres what we do know. The hope is that the market selloff really does sort of get a little bit of legs underneath it when we get some more information. So, maybe those corporate earnings are better than expected. If we get another Quarterly Earnings where its a negative earnings, it will be the third in a row. It hasnt happened since 2009. Also, we would like to see oil prices stabilize. They dont have to go up by a lot, they just have to stop falling. And finally, of course, what we need to know is, how is the u. S. Economy doing . If we have more information to prove that were on the right track, i think things will calm in the absence of information, fear dominates, and thats when we get nasty days like today.
