Failure of testis to descend, occurs in 45 male neonates. Causes infertility, must be surgically corrected 2-3years old.

Question 15

what is testicular cancer?

Answer 15

Interstitial and Sertoli cells tumors are rare. (95%) are germ cell tumors that appear after puberty. Seminoma is a malignant germ cell tumor.

Question 16

describe male infertility

Answer 16

*
Decreased semen quality is a major cause of male infertility. Oligospermia: low sperm count less than 15million/ml
Azoospermia: no sperm in ejaculate
*
Abnormal sperm morphology and flagellar defects (PrimaryciliarydyskinesiaPCD)
*
Spermiation failure: spermatidsare notreleased, are retainedand phagocytosedbythe Sertoli cell.
