2. Figure 1
Blood serum hormone levels of luteinizing hormone (LH) (A), follicle-stimulating hormone (FSH) (B), testosterone (C), sex hormone-binding globuline (SHBG) (D), free testosterone (E), estradiol (F), and prolactin (G) in total values. Data are presented as mean with standard error of the mean (SEM) (A1-G1). Blood serum hormone levels according to the clinic of origin (A2–G2) of n = 80 patients. The blue line marks the male and the red line marks the female reference line. Significant differences are indicated as *P < 0.05, if **P < 0.005, if ***P < , and if ****P <

Weight of testicular tissue with capsule ing according to the level of spermatogenesis (A). Results for subjects with complete spermatogenesis (CS), meiotic arrest (MA), spermatogonial arrest (SPG-A), Sertoli-cell-only syndrome (SCO), and tubular shadows (TS) are shown as mean with SEM. Significant differences are presented as *P < 0.05, if **P < 0.005, if ***P < , and if ****P < B and C show the correlation of testicular weight (with capsule in g) and testosterone (nmol/L) and free testosterone (pmol/L), respectively

Micrographs of representative periodic acid-Schiff (PAS)-stained testicular tissues (A) with tubular shadows (A1), Sertoli-cell-only (SCO) (A2), spermatogonial arrest (A3), meiotic arrest (A4) and complete spermatogenesis (A5). The scale bar represents 20 μm. Total number of tissues with a specific state of spermatogenesis (B). Number of subjects with a specific state of spermatogenesis according to the clinic of origin (C). Black bars represent clinic A, dark grey bars, clinic B and light grey bars clinic C

Intratesticular testosterone (ITT) measurements in pmol/g (n = 159) according to the level of spermatogenesis (A) and according to the clinic of origin (B). Data are presented as mean with standard error of the mean (SEM). CS, complete spermatogenesis; MA, meiotic arrest; SPG-A, spermatogonial arrest; TS, tubular shadows. The red lines indicates the reference lines at 8,000–12,000 pmol/g. Significant differences are marked as *P < 0.05, if **P < 0.005, if ***P < , and if ****P <
