8. Subject has current or history of severe renal or hepatic impairment.
9. Subject has current or history of thromboembolic or blood coagulation disorder.
10. Subject has current or history of cerebrovascular incident (e.g. bleeding, stroke or transient ischemic attack).

12. Subject is heterozygous or homozygous for Factor V Leiden.
13. Subject has clinically significant abnormal findings at physical examination other than those related to COPD.
14. Subject has used transdermal testosterone therapy within 14 days or intramuscular testosterone therapy within 30 days prior to screening blood draw.
15. Subject has used any form of hormone therapy affecting estrogen and/or androgen metabolism within 30 days prior to screening blood draw.
16. Subject has used any other injectable hormonal therapy (e.g. luteinizing hormone releasing hormone (LHRH)-antagonist or- agonist, growth hormone (GH) therapy) within 30 days prior to screening blood draw.
17. Subject has used any other medication affecting the Hypothalamic-Pituitary-Gonadal (HPG)-axis within 30 days prior to screening blood draw.
18. Subject has used any dietary supplements and/or herbal therapies affecting estrogen and/or testosterone metabolism or the HPG axis within 30 days prior to screening blood draw.
19. Subject is using potent inhibitors of CYP3A4 (e.g. ketoconazole, ritonavir, etc) on Day 1 or intends to use these medications during the study.
20. Subject is using potent inducers of CYP3A4 on Randomization Day 1or intends to use these medications during the study.
21. Subject is using medication metabolized by CYP2B6, CYP2C9, CYP2C19 and CYP3A4 and having a narrow therapeutic index on Day 1 or intends to use these medications during the study
22. Subject consumes more than 14 drinks containing alcohol per week. (One drink = 1.5 oz. of distilled spirits, or 12 oz. of beer, or 5 oz. of wine.).
23. Subject has a history of or current drug abuse within 6 months prior to screening visit.
