The patient speaks, reads, and understands the English language at a sixth grade reading level or higher; 3. The patient is willing to have photographs taken and/or be video recorded while he completes study tasks, which will be de-identified prior to any potential use of the image(s) for scientific or educational purposes; 4. The patient has sufficient availability to participate in the study and to comply with the study schedule; 5. The patient has his own transportation to and from the study site; 6.

The patient has a documented history of hypogonadism. Diagnosis must include documentation of consistent signs and symptoms of androgen deficiency; 11. Patients in good health as determined by the Investigator and based on medical history, physical examination, vital signs, electrocardiogram (ECG), and clinical laboratory tests; 12. All male patients must practice effective contraception during the study and for 30 days after receiving the last dose of study drug. Acceptable methods of birth control include condom with spermicide, vasectomy, or monogamous relations with a female partner who is of non child-bearing potential (post-menopausal, surgical, or congenital sterility) or is of child bearing potential and practicing a reliable method of contraception (hormonal contraception, double barrier methods with spermicide, or intrauterine device); and 13. Patients must have the ability to provide written informed consent and comply with all study requirements and restrictions including the study visit schedule. Exclusion Criteria Patients will be excluded from participation in the study if any of the following criteria apply: 1. Failure to meet 1 or more Inclusion Criterion; 2. The patient has participated in interviews, focus groups, or studies for any medical products or therapies within the past 3 months or in a prior QST auto-injector usability study, clinical trial, and/or has previous exposure to the investigational device; 3. The patient or someone he lives with works or has worked for a Marketing/Market Research Company, pharmaceutical or medical device company, a manufacturer, distributor, or wholesaler of non-prescription drug products, or a government health agency; 4.

History of intolerance, allergy, or idiosyncratic reaction to testosterone products; 7. Unstable psychiatric illnesses; 8. Lifetime history of psychosis, suicidal behavior, bipolar disorder, or personality disorder; active suicidal ideation within 6 months prior to screening; or inadequately treated depression. Note: Patients with depression who have been adequately treated and with stable response for 3 months may be admitted into the study at the Investigator's discretion; 9. Body mass index 40 kg/m2; 10. Hematocrit 52% at Initial Screening Visit; 11. Individual history or current evidence of breast or prostate cancer; 12. Other malignancy diagnosed or treated within 5 years of the date of Initial Screening Visit with the exception of non-melanoma carcinoma of the skin; 13.

Presence of prostate nodule or induration upon digital rectal exam; 15. Obstructive uropathy of prostatic origin and of a severity that, in the opinion of the Investigator, contraindicates the use of testosterone; 16. Patients with poorly controlled diabetes.
