It is the hormone estrogen. It is secreted by ovaries.
The hormone that plays a crucial role in the development and release of a secondary oocyte is luteinizing hormone (LH). It is released by the pituitary gland and triggers ovulation, the process by which the mature ovarian follicle releases the secondary oocyte.
Follicle-stimulating hormone, or FSH, stimulates the ovaries. The hormone triggers the growth of immature ovarian follicles, which eventually culminates in the release of a mature egg.
It acts on inferior pitutory.It triggers secretion of growth hormone.
the hormone FSH ( Follice Stimulating Hormone) triggers the menses (period) in a healthy female. During the menses, the uterine lining is being shed.
GnRH
During puberty, the main hormone responsible for the changes is called gonadotropin-releasing hormone (GnRH). This hormone triggers the release of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) from the pituitary gland, which in turn stimulate the growth and maturation of sex organs and the development of secondary sexual characteristics.
The pituitary gland produces FSH which starts the development of a woman's egg cell in a follicle in one of the ovaries.The ovary produces oestrogen which causes the thickening of the uterus lining.The pituitary now produces LH which causes ovulation and stimulates the empty follicle to produce progesterone.Progesterone causes the lining of the uterus to get thicker ready for the fertilised egg.If the egg is not fertilised, production of oestrogen and progesterone stops, the lining of the uterus breaks down and menstruation occurs.
luteinizing hormone
The hormone is FSH - follicle stimulating hormone.
starts at age 11
Luteinising hormone (LH) is made by the pituitary gland and stimulates the mature egg to be released from the ovary, this is called ovulation.
The name of the hormone is leuteinizing hormone. It is secreted by the anterior lobe of the pituitary gland. It is released in middle of the menstrual cycle, normally.
