Vedclass · Answer

(A) Menopause is characterized by the cessation of the menstrual cycle due to the depletion of ovarian follicles. As the ovarian follicles are exhausted (follicular atresia),the production of estrogen and progesterone drops significantly. These hormones normally exert a negative feedback effect on the anterior pituitary gland to regulate the secretion of gonadotropins ($FSH$ and $LH$). Due to the absence of this negative feedback,the anterior pituitary secretes high levels of gonadotropins into the blood. Therefore,both the Assertion and the Reason are correct,and the Reason provides the correct explanation for the Assertion.

$A$. Implantation	$i$. Vagina
$B$. Capacitation	$ii$. Ovary
$C$. Folliculogenesis	$iii$. Uterus
$D$. Fertilisation	$iv$. Fallopian tube

$A$: After menopause,the levels of blood gonadotropins rise markedly.
$R$: At the time of menopause,all the ovarian follicles are converted into follicular atresia,and the ovaries do not respond to the gonadotropins.
