"Israeli Researchers Develop Lab-Made Sperm to Combat Male Infertility"

Israeli researchers at Bar-Ilan University have developed organoids of male testicles that can synthesize testosterone, regulate reproductive functions, and potentially produce sperm in the laboratory, offering hope for infertile couples. The breakthrough could significantly advance understanding of male infertility and sexual development disorders, with potential therapeutic applications for disorders of sexual development and infertility. The researchers plan to further develop the technique using human samples, potentially aiding children being treated for cancer who may later struggle with fertility.
