Primary Outcome Measures:
  • The primary efficacy variable will be the proportion of volunteers with ovulation in at least one of the treatment cycles 2 and 3 [ Time Frame: 4 months ]

Secondary Outcome Measures:
  • The primary efficacy variable will be the proportion of volunteers with ovulation in at least one of the treatment cycles 2 and 3 [ Time Frame: 4 months ]
