🗑
|
||||
| Low semen volume: may be due to: | retrograde ejaculation or androgen insufficiency
🗑
|
||||

🗑
|
||||
| Decreased LH: causes | Testicular tumors; secondary testicular fail; hypopituitarism; hypothalamic-pituitary dysfn
🗑
|
||||
| FSH normal range | 1.5-14.0 mIU/mL
🗑
|
||||
| Elevated FSH causes | primary gonadal failure, testicular agenesis, alcoholism, gonadotropin-secreting pituitary tumors
🗑
|
||||
| Decreased FSH causes | Anterior pituitary hypofunction, hypothalamic disorders
