Outcome Measures

Primary Outcomes (1)

  • Gonadotropin Suppression

    To quantify the gonadotropin suppressive activity of 4 weeks daily therapy of a combination transdermal gel containing 8.3 mg Nestorone® (NES) gel and 62.5 mg (1.62%) testosterone (T) gel, and of T gel (1.62%) alone. Specifically, the proportion (and 95% CI) of men who suppress both gonadotropins (luteinizing hormone \[LH\] and follicle-stimulating hormone \[FSH\]) to ≤ 1 IU/L in each group, will be quantified.

    4 weeks

Secondary Outcomes (16)

  • Gonadotropin and Follicle-stimulating Hormone Suppression

    4 weeks

  • Change in LH and FSH Concentrations

    4 weeks

  • Acceptability and Satisfaction as Measured by the Contraceptive Gel Acceptability and Satisfaction Questionnaire by Comparing T and NES Serum Concentrations.

    4 weeks

  • T Serum Concentrations

    8 weeks

  • Secondary Outcome # 6 Part 1a: A Composite Safety of the Combined Gel Determined by Outcomes of CBC (Hemoglobin)

    4 weeks

  • +11 more secondary outcomes

  • Clinically significant abnormal physical findings at screening;
  • Elevated PSA (levels ≥ 4 ng/mL), according to local laboratory normal values;
  • Abnormal serum chemistry values, according to local laboratory normal values that indicate liver or kidney dysfunction or that may be considered clinically significant;

  • EKG abnormal and clinically significant and QTC level longer than 450msec;
  • History of hypertension, including hypertension controlled with treatment;
  • Known history of primary testicular disease or disorders of the hypothalamic-pituitary axis;
  • Known hypersensitivity to progestins or androgen;
  • Family or personal history of venous thromboembolism;
  • Benign or malignant liver tumors; active liver disease;
  • Known history of reproductive dysfunction including vasectomy or infertility;
