In a life cycle, a woman’s body is vulnerable to a variety of changes. The cycle of these changes in women every month, positively for pregnancy is called menstrual cycle. When an ovum is unfertilized, the uterus lining sheds and leads to hemorrhage, called menstruation. In a girl, menstruation starts from the age of 10 to 15 when she attains puberty and this beginning is known as menarche. The ending of menstruation is known as menopause which takes place at the age range of 50.
The first day of bleeding is marked as the first, day of a menstrual cycle and period from one menstrual cycle to another can vary from 28 to 30 days.
Before discussing the different phases of menstrual cycle, it is important to have a glimpse of female reproductive system and organs involved in this cycle. They mainly include:
A pair of ovaries which stores, nourishes and releases ova.
Uterus (womb), where implantation of a fertilized egg takes place and the fetus develops.
Pair of the fallopian tube connecting the ovaries and uterus.
The count of the ovum in each ovary is decided and fixed before the birth of a girl. As she reaches puberty, hormones stimulate the development and release of one ovum per month. This continues till menopause.

Menstrual cycle
Female Reproductive System undergoes some changes at puberty stage. Those changes occur at the interval of every 28-30 days.
These repetitive changes are called as Menstrual cycle.
Menstrual cycle is a natural process. It is controlled by Four hormones
namely FSH ( Follicle Stimulating Hormone ) , Luteinizing Hormone (LH) , estrogen and Progesterone.
One of the several follicles in the ovary starts to develop along with the oocytes present in it, under the effect of FSH.
This developing follicle secretes estrogen. Endometrium of the uterus starts to develop (during first cycle ) or regenerate ( during subsequent cycles ) under the effect of estrogen.
Meanwhile , developing follicle completes it's development. It bursts under the effect of the Luteinizing Hormone and the oocytes are released. This is ovulation.
Remaining tissues of the burst follicle forms the corpus luteum. Corpus luteum starts to secrete progesterone.
Endometrial glands secrete their secretion under the effect of the progesterone. Such endometrium Is ready for implantation of embryo.
This is Menstrual Cycle.
