Description

Inclusion Criteria

Men who meet all the following criteria are eligible for enrollment in the trial:

  1. Male volunteers in good health as confirmed by physical examination, medical history, and clinical laboratory tests of blood and urine at the time of screening
  2. 18 to 50 years of age
  3. BMI ≤ 33 calculated as weight in Kg/ (height in cm) 2
  4. No history of hormonal therapy use in the last six months prior to the first screening visit
  5. Subject will agree to use a recognized effective method of contraception with his partner (i.e. at a minimum, use double-barrier contraception) during the course of the study treatment and recovery phase
  6. In the opinion of the investigator, subject is able to comply with the protocol, understand and sign an informed consent and HIPAA form
  7. Does not meet any of the exclusion criteria.

Exclusion Criteria:

Men who meet any of the following criteria are NOT eligible for enrollment in the trial:

  1. Men participating in another clinical trial involving an investigational drug within the last 30 days prior to the first screening visit
  2. Men not living in the catchment's area of the clinic or within a reasonable distance from the site
  3. Clinically significant abnormal findings at screening
  4. Elevated PSA (levels ≥ 4 ng/mL), according to local laboratory normal values
  5. Abnormal serum chemistry values, according to local laboratory normal values that indicate liver or kidney dysfunction or that may be considered clinically significant. Other abnormal lab values may also be exclusionary, at the discretion of the investigator
  6. Sperm concentration below 15 million/mL in more than one of three screening samples
  7. Use of androgens or body building substances within 6 months before first screening visit
  8. Diastolic (D) blood pressure (BP) ≥ 85 and Systolic (S) BP ≥ 135 mm Hg; (BP will be taken 3 times at 5 minute intervals and the mean of all measurements be considered)
  9. History of hypertension, including hypertension controlled with treatment
  10. Known history of primary testicular disease or disorders of the hypothalamic-pituitary axis
  11. Known hypersensitivity to progestins
  12. Family or personal history of venous thromboembolism
  13. Benign or malignant liver tumors; active liver disease
  14. History of breast carcinoma
  15. Known history of reproductive dysfunction including vasectomy or infertility
  16. Known history of cardiac, renal, hepatic or prostatic disease
  17. A serious systemic disease such as diabetes mellitus or morbid obesity (body weight greater than 120% of ideal body weight or BMI limitation as above)
  18. History of sleep apnea
  19. Known or suspected alcoholism or drug abuse that may affect metabolism/transformation of steroid hormones and study treatment compliance
  20. Known dermatitis or severe skin disorder
  21. Partner is known to be pregnant
  22. Men desiring fertility within the first 24 weeks of study participation.

Men participating in competitive sports where drug screening for prohibited substances (including anabolic steroids) is routine will be advised of the relative and temporary hazards that participating in this study may have for their fertility or sporting status.
