Figure 3: Follow-up time required to achieve different thresholds of semen concentration (Kaplan–Meier analysis). (a) Cumulative percentage of patients in the hCG/TU group (n = 54) and the hCG group (n = 53) to achieve sperm concentration >0 ml−1 (P = 0.613). (b) Cumulative percentage of patients in the two groups to achieve sperm concentration ≥15 × 106 ml−1 (P = 0.282). hCG: human chorionic gonadotropin; TU: testosterone undecanoate.
