Patient case (clinical description): A 19-year-old male came to clinic with some sexual concern.  He recently engaged in a relationship and is worried about the satisfaction of his girlfriend. He has a "baby face" according to his girlfriend's statement and he is not as muscular as his classmates.  On physical examination, there is some pubic hair and poorly developed secondary sexual characteristics. He is unable to detect coffee smell during the examination, but the visual acuity is normal. Ultrasound reveals the testes volume of 1-2 ml. The hormonal evaluation showed serum testosterone level of 65 ng/dL with low levels of GnRH.

Patient's own account: I'm 19 years old guy and I just went to see a doctor at the clinic after I just got with my girlfriend. I'm kinda worried because she thinks that I have a baby face and to be honest, I'm way less muscular than my classmates. I don't have much hair down there, and yes, I don't have that macho look. The doctor made me smell some coffee and I couldn't smell anything special. I also had some eyesight checkups and the doctor told me everything was normal. I got my test results back and it says: testes volume is 1-2 ml and serum testosterone level of 65 ng/dL with low GnRH levels.

Clinical trial: The Effect of Testosterone Topical Solution (LY900011) in Hypogonadal Men With Suboptimal Response to a Topical Testosterone Gel

Eligibility criteria:
Inclusion Criteria:

          -  Able to read, understand, and provide signed informed consent before starting trial

             therapy prior to Screening)

          -  Male participants with a diagnosis of hypogonadism and documented biochemical failure
             (total testosterone <300 ng/dL) when treated with the highest dose of a topical
             testosterone gel tolerated by the participant. Documentation of biochemical failure
             includes: the name and dose of the topical testosterone gel, a lab report showing a
             total testosterone level <300 ng/dL while on therapy, or a written chart report
             stating that there was a clear lack of efficacy, including the participant's serum
             total testosterone level at the time of failure

          -  Screening serum total testosterone level of <300 ng/dL (based on the average of 2
             morning blood samples taken at least 30 minutes apart) at Screening

          -  Prostate Specific Antigen (PSA) <4 nanogram per milliliter (ng/mL) at Screening

          -  If the participant is receiving testosterone replacement therapy and is willing to
             discontinue testosterone replacement therapy to enter the study, their screening total
             testosterone level cannot be checked until at least 14 days after discontinuing
             topical therapies, or after at least 28 days for participants using short-acting
             intramuscular (IM) therapies

          -  International Prostate Symptom Score (IPSS) total score >19 at Screening

          -  Hematocrit ≥50% at Screening. For sites located at elevations ≥4500 feet, participants
             will be excluded with hematocrit >54% according to investigator discretion. Any
             participant with a hematocrit >54% at later study visits will be withdrawn from the
             study

          -  Significant history of allergy and/or sensitivity to the drug products or excipients,
             including any history of sensitivity to testosterone and/or sunscreens

          -  Dermatologic condition in underarm area that might interfere with testosterone
             absorption (for example, eczema) or that could be exacerbated by topical testosterone
             replacement therapy

          -  History of luteinizing hormone-releasing hormone (LHRH) antagonist or agonist
             treatment in the 6 months prior to Screening

          -  Exhibit any evidence of congestive heart failure [New York Heart Association (NYHA)

             minute (mL/min) as determined by the Cockcroft-Gault formula] at Screening

          -  Exhibit a history of severe liver disease or clinical evidence of hepatic impairment
             at Screening

          -  Any condition that would interfere with the participant's ability to provide informed
