SpermCheck-V test results in representative semen samples from trial participants in sperm suppression phase (sperm concentrations <5 million/ml). The upper positive control line (C) indicates all SpermCheck-V test procedures were performed correctly. The lower positive test line (T) indicates sperm concentrations were above the threshold (>0.2 million/ml) in A (4.8 million/ml), B (1.13 million/ml), and C (0.23 million/ml. There is no line (negative result) visible when sperm concentrations were 0.18 million/ml in D and zero (azoospermia) in E. SpermCheck-V test results were read and photographs were taken at 7 minutes after loading samples into test cartridge.
