Several hormones are involved in the female menstrual cycle, the ovaries produces oestrogen which causes changes at puberty and helps control the menstrual cycle, and stimulates production of LH.
It keeps the endometrium (the uterus lining) thick to prepare the uterus for implantation of the zygote. In the start of the menstrual cycle, it is the drop in the levels of this hormone that trigger the break down of the uterus lining, causing menstruation. So in a sense it is what prevents menstruation.
Moreover, progesterone is what prevents the pituitary gland from secreting the hormones FSH and LH which have important roles in the rest of the cycle.
the role of oesrogen in the menstual cycle is when the female is on her period and the oestrogen helps the woman to produce and has more chance of having a baby
It thickens the uterus lining during the menstrual cycle
Estrogen stops the release of eggs.

oestrogen and progesterone
Progesterone looks to be more important for menstruation. You need fairly large dose of oestrogen in absence of the progesterone to maintain the menstrual cycle.
They are the two main hormones regulating the menstrual cycle and fertility.
Oestrogen and progesterone are the two hormones involved in menstruation. Both are secreted by the ovaries.

The menstrual cycle occurs when the egg is not fertilised by sperms and comes out through the vagina in the form of blood and an egg. It is regulated by the ovary and the uterus.
luteinizing hormone
Oestrogen and the progesterone are the two hormones that are responsible for the menstruation and the menopause. Menopause is marked by the absence of the two.
GnRH from the hypothalamus stimulates RH and FSH from the anterior pituitary gland. These start menarche, and are assisted during the menstrual cycle by oestrogen and progesterone
Oestrogen, Progesterone and small amounts of Androgen and Testosterone (male hormones) are produced in the Ovaries. Oestrogen: regulates the menstrual cycle and prepares the breasts for milk production. Progesterone: prepares the lining of the uterus, for implantation of a fertilized egg, and helps maintain the pregnancy.
