United States50 participantsStarted 2019-05-10

Plain-language summary

The objective of this study is to use ultrasound-guided rete testis flushing and aspiration technique to retrieve sperm, non-surgically, from the testes of azoospermic men. If sperm are retrieved by this method, it will provide a direct benefit to the infertile men. This protocol will also establish the safety and feasibility of the ultrasound-guided rete testis injection approach in consenting men before the approach is translated to teenage boys.
