Answer to Question 1
biopsy
Biopsies are procedures in which samples of tissue are taken for evaluation to confirm or locate a lesion.
Answer to Question 2
Sperm
The two oval testes (gonads) are enclosed in the scrotum, a saclike structure that lies suspended from the exterior abdominal wall. This position keeps the temperature in the testes below normal body temperature, which is necessary for viable sperm production and storage. Each testis contains one to three coiled seminiferous tubules that produce the sperm cells.
