#Sperm Grown in a Lab for the first time In a breakthrough that could lead to a treatment for thousands of infertile men, scientists have grown human sperm cells in a laboratory for the first time. The Kallistem laboratory, a private research facility based in Lyon, France, has turned spermatogonia into mature sperm in test tubes. This is a feat that scientists have been trying to tackle for the past 15 years. This complex process usually takes 72 day to take place in the human body. allistem is addressing a major issue whose impacts are felt worldwide: the treatment of male infertility, Isabelle Cuoc, the CEO of Kallistem Laboratory, told the Daily mail. ur team is the first in the world to have developed the technology required to obtain fully formed spermatozoa in vitro with sufficient yield for IVF, Cuoc added. The findings have not yet been published in a peer review journal, but Kallistem plans to conduct preclinical trials next year. If these trials are successful, the company will remove a sample of immature spermatogonia from a man and transform the genetic material into mature sperm. Then, an IVF procedure will be used or the sperm may be frozen for later use. This research paves the way for future treatments that may preserve and restore male fertility which impacts an estimated 50,000 men each year. The overall market for this technology, Kallistem predicts, would be worth more than $2. 58 billion
