Menopause is characterized primarily bya. primary ovarian failure.b. loss of estrogen secretion from the ovary due to a decrease in LH.c. loss of estrogen secretion from the ovary due to a decrease in FSH.d. a decrease in FSH and LH due to increased inhibin.e. a decrease in FSH and LH due to a decrease in GnRH pulses.
In women, new follicles do not mature as long as the corpus luteum is maintained because
a
hormones released from the corpus luteum inhibit ovarian secretion
b
hormones released from the corpus luteum inhibit buildup of the endometrium
c
hormones released by the endometrial lining of the uterus during the proliferative phase inhibit the maturation of new follicles
d
there is insufficient energy to support both maintenance of the corpus luteum and follicle development
e
hormones from the corpus luteum inhibit release of LH (luteinizing hormone) and FSH (follicle stimulating hormone)
Plasma concentrations of LH and FSH rise dramatically after menopause. This is because (select one)
a. The negative feedback of gonadal steroids is no longer present
b. Rising gonadotrophins maintains the fertility of older animals
c. Fertility in older woman declines
