(A)
Leydig cells
(B)
Sertoli cells
(C)
Chromaffin cells
(D)
Interstitial cells
Show Answer & NCERT Explanation

Providing energy to sperms
(B)
Lubrication of the penis
(C)
Immunological protection
(D)
Stimulating uterine contractions
Show Answer & NCERT Explanation

Which hormone is essential for the maintenance of the endometrium?
(A)
FSH
(B)
LH
(C)

What is the role of hCG in early pregnancy?
(A)
Causes uterine contractions
(B)
Maintains the corpus luteum and its progesterone output

Parturition is induced by which hormone released from the maternal pituitary?
(A)
Estrogen
(B)
Progesterone
(C)
Oxytocin
(D)
Prolactin
Show Answer & NCERT Explanation
Correct Answer: (C) Oxytocin
Parturition (childbirth) is triggered when the fully developed fetus causes the fetal ejection reflex, leading to the release of oxytocin from the maternal pituitary, which induces strong uterine contractions.
