Regulate erection
Explanation - Seminal vesicles produce a fluid rich in fructose that provides energy for sperm.
Correct answer is: Secrete fructose-rich fluid
Q.9 Which hormone triggers ovulation?
FSH
LH
Estrogen

Explanation - Sertoli cells support and nourish developing sperm during spermatogenesis.
Correct answer is: Support spermatogenesis
Q.11 Which female structure produces the female gametes?
Ovary
Uterus

Explanation - The ovaries produce ova (female gametes) and secrete estrogen and progesterone.
Correct answer is: Ovary
Q.12 Which part of sperm contains enzymes to penetrate the egg?
Tail
Head
Acrosome

Correct answer is: Uterus
Q.17 Which structure in females is homologous to the penis in males?
Uterus
Clitoris
Vagina
Ovary
Explanation - The clitoris is homologous to the penis as both develop from the same embryonic tissue.
Correct answer is: Clitoris
Q.18 What is the function of follicle-stimulating hormone (FSH) in males?

Explanation - The midpiece of sperm contains mitochondria that produce ATP for motility.
Correct answer is: Midpiece
Q.20 Which hormone peaks just before ovulation?
Estrogen
