Question

Discuss the role of hormone in menstrual cycle?

Answer 1

The hormones estrogen and progesterone control the whole process
Menstrual cycles vary in length: some last longer than 28 days, while others are shorter
The average woman will have approximately 500 periods in her lifetime
Some women bleed for only 3 or 4 days; others bleed for a week
The follicular phase begins with an increase in follicle stimulation hormone (FSH), which causes increases in luteinizing hormone (LH) and gonadotropin-releasing hormone (GnRH). Concurrent increases in estrogen levels cause increases in progesterone, stimulating proliferation of the endometrium.

The menstrual cycle is the physiological change that occurs under the control of the endocrine system in fertile women for the purposes of sexual reproduction and fertilization. It is divided into three stages: follicular phase, ovulation, and the luteal phase.

Answer 2

The menstrual cycle is regulated by Luteinizing hormone and Follicle Stimulating hormone which are produced by pituitary gland, promote ovulation and stimulate ovaries to produce estrogen and progesterone.
