ST. LOUIS (KGO) --A new fertility treatment is giving women, who hope to get pregnant later in life, an alternative to freezing their eggs.
A 4 year old boy named Grant is among the first wave of babies in the world conceived through the use of frozen ovary tissue. His mom, Amy was diagnosed with Hodgkin's lymphoma at 19 years old and faced sterility.
The procedure enables women to freeze up to hundreds of thousands of eggs.
Dr. Sherman Silber of the Infertility Center of St. Louis recommended the procedure, but warned Amy it may not work.
After 12 years, Amy had her frozen ovary tissue re-implanted.
Sliber says ovary freezing has worked successfully for 75 percent of the women he's tried it on.
The procedure costs around $10,000 while egg-freezing can cost up to $25,000.
