How long Hypogonadism studies take

Of 21 phase 4 interventional studies under Hypogonadism, half reached primary completion within 52 months of starting, counting those still running.

Start to primary completionEvery sponsorIndustryNon-industry
Phase 132 mo18–57 · 13 studies——
Phase 452 mo18–72 · 21 studies——

Each figure is the month by which half the studies had reached primary completion, with the range in which the middle half did. Studies still running count until their last registry update; studies that stopped early are left out. Phase 1 includes early phase 1; observational means prospective or not stated, as retrospective and cross-sectional studies date a window of data rather than a study.
