Test: Menstrual Cycle - Class 12 MCQ

Corpus luteum produce or maintained by LH

After age of 45 or 50 Menopause

Corpus luteum is maintained by leutinizing hormone and it produce Progesterone

First FSH produced and than estrogen from follicle and than corpus luteum produce progesterone.

When level of Progesterone fall than menstruation occur.

When all follicles get finish than menopause 

In last of proliferative phase or follicular phase ovulation occur.

human chorionic Gonadotropin is responsible for maintenance of Corpus luteum.

LH, FSH and Estrogen is responsible is for menstrual control.

Follicular phase last from 5th to 14th day of cycle.

Degeneration of corpus luteum lead to decrease level of progesterone

Progesterone and Estrogen is maintain Endometrium.

Primary follicle development not related with progesterone level.

Estrogen is responsible for proliferation of Endometrium.

Progesterone maintain endometrium and maintain pregnancy.

In post ovulation FSH level is least

Immediately after ovulation, the layer that forms around the ovum is called corona radiata.

Rapid secretion of LH leading to its maximum level during the mid-cycle called LH surge induces rupture of Graafian follicle and thereby the release of ovum (ovulation).

Both LH and FSH attain a peak level in the middle of the cycle (about the 14th day). Rapid secretion of LH leading to its maximum level during the mid-cycle called LH surge induces rupture of Graafian follicle and thereby the release of ovum (ovulation).

Inhibin can inhibit GnRH

After Menstruation menstrual cycle is in Proliferative phase 

HCG produce after implantation and appear in Urine and can be use a test for pregnancy

Primates show menstrual cycle and cow and similar animals show estrous cycle.

Pregnancy is responsible for high level of progesterone which inhibit both FSH and LH so ovulation not occur.

When your body reaches a certain age, your brain releases a special hormone that starts the changes of puberty. It's called gonadotropin-releasing hormone, or GnRH for short.
