Outcome Measures

Primary Outcomes (1)

  • Proportion of patients with a mean decrease in sperm concentration to 7.5 x 10[6]/mL or below, without a single sperm concentration ≥ 20 x 10[6]/mL, at 3 or 6 months. This proportion is considered of clinical relevance if greater than 30%.

    From baseline to end of study.

Secondary Outcomes (1)

  • Semen volume, sperm motility and sperm morphology change

    From baseline to 3 & 6 months

Study Arms (1)

1

EXPERIMENTAL

Oral bosentan tablets

Drug: bosentan

Interventions

Oral bosentan tablets 62.5 mg twice daly for 4 weeks, then 125 mg twice daily for 20 weeks.

Also known as: Tracleer (R)
