II. Cloze Test (10%)
(A)One thing that makes sperm such a profitable commodity is that the customer base is huge. The World Health Organizationestimated in 2006 that there were 60 million to 80 million infertile couples worldwide. Thus far，most international sperm business has been for heterosexual couples with fertility challenges，but that is changing as more cultures accept lesbians and single parents—two groups that 11 by some estimates up to 60% of the U.S. market.America’s ejaculatory exceptionalism is not a result of American men’s superior virility. Rather quality control and wide product selection are the keys. What’s more, the U.S. still always makes anonymity an option—and that’s driving overseas customers intoAmerican arms. While anonymity helps the U.S. 12 this market effectively, it’s the quality issue that really keeps overseasbuyers flocking. Dads are profiled according to their height，appearance and education level. A man with a Ph.D. can make as much as $500 per ejaculation. Lower-end donors，who still need at least a college degree and a minimum height of 176 cm, can earn about $60 a—13_. Depending on how dense his sperm is and the mobility of his swimmers~critical to surviving the freezing process~a donorcan make up to $60,000 over two years，the maximum amount of time most clinics use a donor.Sophisticated as all this seems, we are still in the Wild West phase of global sperm sales. Lucrative pay has raised questions aboutsperm profiteering. What’s more, one man in Britain who donated for over 30 years has 一14 more than 15000 children. Suchstories prompted Britain to restrict the number of children a donor can spawn, including his own, to ten. The FDA has no limits on the number of offspring a donor may have, nut most banks say they limit men to 25 or 30 children. That said，there’s evidence that those guidelines can be loose. More worrisome，donors could be unwittingly spreading genetic diseases. Another riskthat of ethnicitymix-up for overseas buyers—is not just theoretical; it’s happened. Finally, when a __15_donor produces lots of half siblings whogrow up near one another, accidental incest could result.
