Lab-Grown Testicles Offer New Hope for Male Infertility Treatment

Scientists have successfully grown testicles in a lab, a breakthrough that could revolutionize treatments for male infertility and reproductive disorders.

• Researchers at Bar-Ilan University in Israel have developed lab-grown testicles from mouse cells, potentially easing male infertility which affects 10% to 15% of American men.
• The artificial testicles closely mimic the structure and function of natural testicles, showing promise for basic research and therapeutic applications.
• The organoids remained viable for up to nine weeks, long enough for the sperm generation and release process to occur in theory.
• This breakthrough could help boys with cancer who may lose fertility due to treatment, by growing fertile sperm in vitro for future use.
• The technology also has potential applications in the livestock industry, aiming to control the sex of farm animals to improve production.
