Conditions
Brief summary
The study involves application of Axiron to each underarm. The study will evaluate the transfer of testosterone from underarms to the clothing items that the participant is wearing and other fabric items washed with participant's' clothes. The study is approximately 6 days, not including screening. Screening is required within 28 days prior to the start of the study.

Exclusion criteria
* Are currently enrolled in a clinical trial involving an investigational product or off-label use of a drug or device, or are concurrently enrolled in any other type of medical research judged not to be scientifically or medically compatible with this study * Are participants who have previously completed or withdrawn from this study or any other study investigating Axiron in the past 3 months * Have known allergies to testosterone solution, related compounds, or any components of the formulation, or history of significant atopy * Have an abnormality in the 12-lead electrocardiogram (ECG) that, in the opinion of the investigator, increases the risks associated with participating in the study * Have an abnormal blood pressure as determined by the investigator * Have a history of or current cardiovascular, respiratory, hepatic, renal, gastrointestinal, endocrine, hematological, or neurological disorders constituting a risk when taking the study medication or that could interfere with the interpretation of the data * Have had lymphoma, leukemia, or any malignancy within the past 5 years except for basal cell or squamous epithelial carcinomas of the skin that have been resected with no evidence of metastatic disease for 3 years * Regularly use known drugs of abuse and/or show positive findings on urinary drug screening * Show evidence of human immunodeficiency virus (HIV) infection and/or positive human HIV antibodies * Show evidence of hepatitis C and/or positive hepatitis C antibody * Show evidence of hepatitis B and/or positive hepatitis B surface antigen * Use of any topical testosterone replacement therapy within the 3 months prior to study entry through study discharge, except for use of Axiron as directed by study procedures * Use of parenteral testosterone replacement (testosterone enthanate, testosterone cypionate) within the 30 days prior to screening. Use of long acting intramuscular testosterone undecanoate 6 months prior to screening, or use of testosterone pellets 12 months prior to screening * Have a dermatologic condition in the underarm area that might be exacerbated by topical testosterone replacement therapy, in the opinion of the investigator * In the opinion of the investigator or sponsor, are unsuitable for inclusion in the study

| Amount of Testosterone on Unworn Textiles Laundered With the Testosterone Exposed T-shirts | 12 hours after application of study drug | This is a summary of the amounts of testosterone measured on unworn textile items washed with t-shirt halves exposed to testosterone in a standard washing machine. Total amounts of testosterone on each laundered item other than the t-shirt halves was calculated based on the weight of the fabric sample analyzed and the total weight of the item, assuming a uniform distribution of testosterone across each item as: (weight of laundered item / weight of laundered sample) x amount of testosterone on laundered sample. |
