Lab-grown sperm cells claim by French
Print Edition
FRENCH scientists say they have succeeded in creating the world’s first lab-grown human sperm cells in what experts said yesterday could be a leap forward in tackling male sterility.
The Kallistem laboratory in Lyon this week announced they had obtained “complete human spermatozoa in vitro,” a world first which scientists have labored toward for some 15 years.
“At the end of 2014 the company was able to produce fully formed human spermatozoa in the laboratory setting, using patient testicular biopsies containing only immature germ cells, or spermatogonia,” the company said in a statement.
“This paves the way for innovative therapies to preserve and restore male fertility, a major issue with global impact; numbers of spermatozoa have declined by 50 percent over the last 50 years.”
The research has not yet been published in a peer-reviewed journal and experts greeted the news with caution, while admitting that if proven, the achievement was a significant breakthrough.
The researchers said it could help tens of thousands of men rendered infertile due to abnormal sperm production.
The company’s estimates, it could provide a market worth over 2.3 billion euros (US$2.58 billion), with 50,000 new patients each year.
“If this is true (the research claims) it is a considerable step forward in treating male sterility,” Professor Israel Nisand, co-founder of the European Bioethics Forum told Le Figaro.
