Description of intervention(s) / exposure
Treatment: Devices - ADAM System

Experimental: ADAM Cohort 1 - The first 5 subjects will be reviewed for safety by a Data Safety Monitoring Board (DSMB) at 30 days post-implantation. The 5 subjects will then be followed up to 24 months or until their semen analyses is = 15 million sperm/mL.

Experimental: ADAM Cohort 2 - An additional 13 subjects will be enrolled and implanted with ADAM. They will be followed up to 24 months or until or until their semen analyses is = 15 million sperm/mL.

Experimental: ADAM Cohort 3 - An additional 4 subjects will be enrolled and implanted with ADAM. They will be followed up to 24 months or until or until their semen analyses is = 15 million sperm/mL.

Experimental: ADAM Cohort 4 - An additional 3 subjects will be enrolled and implanted with ADAM. They will be followed up to 24 months or until or until their semen analyses is = 15 million sperm/mL.


Treatment: Devices: ADAM System
The ADAM System consists of an injectable hydrogel and delivery apparatus that is intended to provide long-lasting, non-permanent vasal occlusion for men, resulting in azoospermia. ADAM is designed to be inserted into the vasa deferentia through a minimally invasive procedure, similar to the no-scalpel vasectomy.
