|---|---|---|---|---|
| FSH | N/A | 1.2–8.6 | 3.3 | 1–10 |
| LH | 0.8 | 1–10 | 2.5 | 1–10 |
| Total testosterone | 33 | 175–780 | 833 | 250–1100 |
| Free testosterone | 3 | 50–247 | 69.9 | 35–155 |
| TSH | 2.8 | 0.35–4.94 | 2.9 | 0.4–4 |
| Free T4 | 0.7 | 0.7–1.5 | 1.1 | 0.7–1.5 |
| ACTH | 12 | 6–50 | 29 | 6–50 |
| Cortisol (08:00) | 2.6 | 3.7–19.4 | 12.3 | 3.7–19.4 |
| Prolactin | 13.5 | 2.6–13.1 | 14 | 3–16 |
| IGF-1 | 20 | 50–317 | 88 | 50–317 |
| Serum sodium | 142 | 135–145 | 143 | 135–145 |
*Preoperative reference ranges are different because they were obtained at outside hospital.
†IGF-1 normalized at 10-week follow-up; adrenal axis normalized at 15 weeks; gonadal axis normalized at 23 weeks; thyroid axis normalized at 10-month follow-up.
ACTH, adrenocorticotrophic hormone; FSH, follicle-stimulating hormone; IGF-1, insulin-like growth factor 1; LH, luteinizing hormone; T4, thyroxine; TSH, thyroid-stimuilating hormone.
