Progesterone and estrogen are secreted by the corpus luteum. Luteinization causes formation of corpus luteum from the ruptured follicle. The LH levels surge prior to ovulation and cause the egg to be ruptured from the follicle.

Luteinizing Hormone (LH) Stimulates certain cells that line the follicle (theca interna cells) to produce progesterone. * Usually only one follicle is boosted to ovulation.

* The drop in FSH after the intermediate level is reached causes the follicle to be receptive to the secondary pituitary hormone, LH which will surge before ovulation. * There is also a maximum level of FSH, only 20-30% above the threshold which must not be exceeded, otherwise too many follicles would develop and multiple ovulations would occur.

* There is an intermediate level of FSH which must be exceeded before the dominate follicle is boosted into its full ovulatory response. * Several days of follicle growth are required before the follicles secrete enough estrogen into the blood stream to signal the hypothalamus/pituitary that the threshold for FSH has been reached. * The level of FSH fluctuates and must reach a threshold level before any follicular growth takes place. FSH stimulates several of the most sensitive follicles in the ovary to begin growing. The pituitary gland also secretes prolactin to stimulate the production of breast milk.ДЇollicle Stimulating Hormone (FSH): is stimulated into production at the beginning of the cycle, because of the decrease in the ovarian hormones, estrogen and progesterone production at the end of the previous cycle. There is a feed back mechanism between the ovaries and the hypothalamus which increases or decreases the amount of FSH and LH produced in the pituitary. * The anterior lobe of the pituitary gland secrets FSH and LH that in turn stimulate the ovaries to mature and release ova (egg(s)). It is a protrusion off of the bottom of the hypothalamus at the base of the brain. The Pituitary is a glandВ is an endocrine gland about the size of a pea and weighs less than 0.02oz. * The hypothalamus is influenced by our environment and emotional state and acts as a major computer in our body analyzing signals from other areas of the brain as well as hormonal signals. * Hormones are chemical messengers that are produced in one part of the body, travel through the blood stream, and affect other parts of the body. * At menarche (first period) and throughout the reproductive life of the woman, the hypothalamus stimulates the pituitary to produce both follicle stimulating hormone (FSH) and luteinizing hormone (LH), which in turn causes the menstrual cycle to occur.

* It controls many physiologic mechanisms including: appetite, thirst, emotional reactions, and temperature. The Hypothalamus is a gland and portion of the brain located above the pituitary gland. The bleed causes estrogen and progesterone levels to fall and the Hypothalamus begins to work. The act of ovulation and menstruation are the result of a hormonal dance between the Hypothalamus (master gland), the pituitary gland, ovaries, and uterus.ДЄ fresh cycle begins with the first day of a womans bleed.

If you already have an understanding of anatomy and physiology feel free to skip to the bottom of these writings. The information in this article will first cover the full function of the glands and organs involved in ovulation so there is groundwork for understanding the overall sequence of events which will be covered at the bottom of this article. This article is intended to shed light on the hormones behind ovulation in a way that any of us could understand.

#Ovulation hormones series

The physiological journey that a womans body goes through every cycle to achieve ovulation is the product of a series of hormones that lead into one another. Ovulation is the release of a ripe fertile egg from the ovary, it is a womans peak time of fertility in the month.
