But a  Mayo Clinic study presented last week at the annual meeting of the  American Urological Association reveals that frozen sperm is just as  effective for in vitro fertilization, or IVF, where sperm is allowed to  fertilize an egg in a lab dish, and the resulting embryo is implanted  within a woman&#8217;s uterus. After reviewing 10 years of data collected at  the Mayo Clinic and comparing birth rates from IVF attempts, researchers  found that the likelihood of a successful pregnancy was the same,  whether the sperm used was fresh or frozen. Though the clinic&#8217;s doctors  still prefer to use fresh sperm, since freezing and thawing reduces  sperm number and motility, couples can now rest easily, knowing they&#8217;re  not jeopardizing their chances of pregnancy if fresh is not available.  &#8220;The in vitro process is long and can be difficult &#8212; emotionally,  physically and financially. These results make the process just a little  bit easier,&#8221; the study&#8217;s senior author, Alan Thornhill, director of the  clinic&#8217;s IVF lab, stated in a press release. <\/span><\/p>\n<h6><em>This news brief appeared in the Discoveries column of the <\/em>Boston Globe&#8217;s<em> Health\/Science section on 5\/18\/2004.<\/em><\/h6>\n","protected":false},"excerpt":{"rendered":"<p>Researchers have long been concerned that using frozen sperm instead of fresh to create test-tube babies might reduce the chances of a successful pregnancy for an infertile couple.
