Explanation:

Question 7

A vasectomy is a procedure where the vas deferens (tubes that carry sperm) are cut or blocked. Option A is wrong as epididymis isn't removed. Option C is wrong as sperm production in testes continues. Option D is wrong as urethra isn't closed. So blocking vas deferens stops sperm from exiting.

Question 8

Seminal glands (seminal vesicles) produce a fluid that makes up most of semen. This fluid has fructose and other substances that provide energy to sperm, increasing their mobility. Option A is wrong (urethra isn't thickened by them). Option C: they don't produce hormones (testes and endocrine glands do). Option D: long - term sperm storage is in epididymis, not seminal glands.

Question 9

Prostate cancer in early stages often has no or very mild symptoms that are easy to miss. Option A: early prostate cancer is not extremely painful. Option B: hair loss isn't an early symptom of prostate cancer. Option D: Prostate cancer can affect men younger than 70 too.
