QUESTION
Which is not a congenital defect?
OPTIONS
(A) Ovarian agenesis
(B) Ovarian hypoplasia
(C) Testicular hypoplasia
(D) Testicular degeneration
ANSWER
(D) Testicular degeneration
EXPLANATION
Testicular degeneration is generally an acquired loss of normal testicular structure or function caused by factors such as heat, inflammation, toxins, or nutritional disease. Ovarian agenesis means failure of an ovary to develop, and ovarian or testicular hypoplasia means inadequate development. Those are developmental defects present from early life, whereas degeneration affects tissue that previously developed.
