Baby born from 21-year-old frozen sperm






CHARLOTTE, N.C., April 13 (UPI) -- The birth of a baby conceived from sperm frozen for 21 years may tie the world record for the longest-frozen, viable sperm, U.S. fertility specialists say. Thirty-eight-year-old Chris Biblis of Charlotte, N.C., was treated for leukemia from age 13-18. In 1987, at age 16, his family encouraged him to freeze his sperm, even though there was no treatment for male infertility at the time.
It was not until 1992 that the first baby was born from intracytoplasmic sperm injection -- a breakthrough fertility technology in which scientists inject a carefully selected healthy sperm cell into a human egg in the lab -- fertility specialists of Reproductive Endocrinology Associates of Charlotte said.
Biblis has been clinically disease-free for more than 20 years. Last May, he and his wife, Melodie, 33, also in excellent health, sought fertility treatment with Reproductive Endocrinology Associates of Charlotte founder and fertility specialist Dr. Richard L. Wing.
"They achieved pregnancy on their first cycle of intracytoplasmic sperm injection used in conjunction with in vitro fertilization, a now-routine procedure for male infertility, using her eggs and his frozen sperm," Wing said in a statement. "We had every reason to expect a perfect baby but are thrilled nonetheless."
