Supersensitive fluorescent semen analysis: validation on azoospermic and oligozoospermic samples.

Objective: To compare the clinical utility of a supersensitive fluorescent semen analysis (SSSA) procedure published by Cooper et al. (2006) with a conventional World Health Organization (WHO)-based semen analysis technique in males with severe oligozoospermia or azoospermia who are undergoing fertility assessment.

Design: Prospective single-center study.
