Which lead sponsors run the most Azoospermia trials? (5)
Shown in this order: most trials first. Lead sponsors the registry classes as industry, NIH, US federal, other government or network. A hospital or university the registry files as government can appear here. Sponsors it classes as academic or other are shown on the full page, because that class cannot separate an institution from a named investigator.

| BAIBYS Fertility | 1 |
| Clinique Ovo | 1 |
