The purpose of this study is to evaluate the pharmacokinetics (what the body does to the medication) and relative bioavailability (the extent to which a medication or other substance becomes available to the body) of JNJ-56021927 when administered as 7 test tablet formulations of JNJ-56021927 compared with the softgel capsule formulation of JNJ-56021927 in healthy male participants under fasted conditions at a single dose of 240 mg.

This is a randomized (the study medication is assigned by chance), open-label (all people know the identity of the intervention), single-center, 8-treatment, parallel-group (each group of participants will be treated at the same time) study. Approximately 120 participants (15 participants in each treatment group) will participate in this study. All participants will be randomly assigned to 1 of 8 possible treatments (A, B, C, D, E, F, G, and H). The study will consist of a screening phase (within 21 days before the first administration of the study medication), a treatment phase with 8 parallel single-dose treatments (8 days); a follow up phase (42 days) and an end-of-study or early withdrawal assessments (Day 57). Safety will be evaluated by the assessment of adverse events, clinical laboratory tests, vital signs, and physical examination which will be monitored throughout the study. The duration of participation in the study for an individual participant will be approximately 78 days.

• During the study and for 3 months after receiving study medication, must agree to use an adequate contraception method (eg, vasectomy, double-barrier, partner using effective contraception), always use a condom during sexual intercourse and to not donate sperm
• Body mass index (weight [kg]/height [m]2) between 18 and 30 kg/m2 and body weight not less than 50 kg

• Non-smoker for 2 months prior to study participation

• Clinically significant abnormal values for hematology, clinical chemistry or urinalysis, physical examination, vital signs or 12-lead ECG at screening or at admission to the study center as deemed appropriate by the investigator
• Presence of sexual dysfunction (eg, abnormal libido or erectile dysfunction) or any medical condition that would affect sexual function
• Use of any prescription or nonprescription medication (including vitamins and herbal supplements), except for acetaminophen within 14 days before the first dose of the study drug is scheduled
