Woman becomes mother after 23 years of ovarian tissue storage

Cassandra Beekan was diagnosed with blood cancer at age 17 and opted to store ovarian tissue before undergoing chemotherapy. Because immediate cancer treatment was necessary, she could not use traditional egg freezing methods. The tissue was stored for 23 years before being re-implanted when she was 44. Beekan successfully became pregnant and gave birth to her first child, London, one month ago. Medical experts believe this is the first successful birth resulting from ovarian tissue frozen for over two decades.
