AI finds hidden sperm, offers hope to infertile men
11 Aug
Summary
- AI system named STAR helps find rare sperm cells.
- STAR system analyzes semen samples with high-speed cameras.
- Azoospermia affects 10% of infertile men worldwide.
Male infertility is a significant concern, contributing to up to 40 percent of all infertility cases globally. For men with azoospermia, characterized by zero or very few sperm, the chances of fathering children were historically grim.
A novel technique called the STAR (Sperm Tracking and Recovery) system, developed by Dr. Zev Williams and his team at Columbia University, is changing this landscape. Launched officially in late 2025, STAR employs artificial intelligence and a high-powered camera to analyze semen samples at an unprecedented rate of 300 images per second.
This AI-driven approach successfully identifies "hidden" sperm cells that are often missed by manual microscopic examination. Across 175 cases, the STAR system has recovered sperm in 26 percent of instances. For example, one couple experienced 19 years of infertility before the STAR system enabled them to have a baby girl.
While STAR cannot assist men with absolutely no sperm, it offers a profound advancement for those with extremely low counts. Research into growing human sperm in labs by companies like Paterna is also underway, potentially offering future solutions for men who do not produce sperm efficiently.
