This study is creating a collection of male biological samples, called a biobank, to help researchers better understand male infertility and assisted reproductive technologies (ART). Researchers are collecting samples like testicular tissue, sperm, and semen that were originally used for diagnosis or ART procedures (like IVF or ICSI) but are no longer needed. If you are a male who has provided such samples, or a sperm recipient using donor sperm, you may be able to donate these leftover samples for future research. The goal is to build this biobank over five years to support future studies. The study is currently unclear about its recruitment status.

Study design

This is an observational study aiming to enroll 1000 male participants. It focuses on collecting biological samples for a research biobank.

What's involved

You would be donating existing biological samples (testicular tissue, sperm, semen) that are no longer needed for clinical use. The record does not specify any additional visits or procedures.

Compensation

Not stated in the trial record.

Follow-up

The primary goal is to establish the biobank, which will be measured at 5 years. There is no specified follow-up for individual participants.
