(es-tra-DIE-ol) TRADE NAME: Estrace TRADE NAME: Progynon An estrogen that is found in mammals. Estradiol is the most potent estrogen; it is formed in the ovary and, to some extent, the testes . Estradiol is converted in the liver to estrone by 17 beta-hydroxysteroid dehydrogenase. It is found in large quantities in pregnant women. Estradiol from the urine of mares and stallions is used to make medical products.
The most potent naturally occurring estrogens in humans.
the most potent naturally occurring estrogen. In men it is naturally produced in small amounts.
The major natural estrogen.
hormone produced by the ovary and placenta that is involved with the development and maintenance of female secondary sex characteristics and function of accessory sex organs and development of the mammary glands.
The most powerful natural estrogen. Produced by the ovarian follicle and corpus luteum in women, and (to a small extent) by the Sertoli cells in men. Also produced by fat cells (through conversion of testosterone) in older women, especially after the menopause. See also: serum estradiol
Estradiol is the primary estrogen produced by the ovaries.
The most potent natural estrogen. Estradiol is produced particularly in the maturing ovarian follicles.
the most powerful female hormone that occurs naturally; synthesized and used to treat estrogen deficiency and breast cancer
The female hormone that is produced by cells that live in the follicle (nest) around the developing egg. There are three estrogens Estrone E-1, Estradiol E-2 and Estriol E-3.
(E2) A naturally occurring female hormone. In the infertility workup, this hormone is usually measured on Cycle Day 3 (Day 1 is the first day of bleeding). E2 and FSH are sometimes interpreted together to determine ovarian reserve and predict response to treatment. Tests for E2 are also done throughout IVF to monitor response to the fertility drugs.
A common form of estrogen in women. At menopause, the ovaries stop producing estradiol, and levels are, therefore, very low in postmenopausal women.
the strongest oestrogenic hormone, secreted by the ovaries of mammals.
The predominant estrogen (hormone) produced by the follicular cells of the ovary.
The predominant estrogen secreted by the ovaries.
The most bioactive and potent of the estrogens found in the body, and the most predominant estrogen produced by the human ovary prior to menopause. Responsible for over 400 functions in the human body.
A form of estrogen. This hormone is produced by developing follicles in the ovary. Measuring levels helps determine progressive growth of the follicles during ovulation induction.
The most active estrogen.
a potent natural form of estrogen produced by the ovaries, placenta and testes.
A form of estrogen produced by the ovary. Estrogen concentrations in the blood are often measured during treatment cycles. close window
a steroid hormone produced by the follicle. It helps regulate the pituitary gland secretion of the hormones FSH and LH, as well as cause the lining of the uterus to grow.
a hormone released by developing follicles in the ovary. Plasma estradiol levels are used to help determine the progressive growth of the follicle during ovulation induction.
The most potent naturally occurring estrogen in humans, which is released from the ovary
A hormone that promotes growth and maintenance of the reproductive system.
The most potent of a class of hormones called estrogens, produced by the follicle, the corpus luteum, and the placenta.
A female sex hormone secreted by the ovary which, in conjunction with progesterone, functions to maintian the uterine mucosa in case fertilization occurs.
A hormone released by developing follicles in the ovary. Estradiol levels are used to help determine progressive growth of the follicles during ovulation induction. It is extremely important to monitor these levels while on fertility drugs to coordinate ovulation and to prevent hyper stimulation.
the most powerful and fertility-impacting of two types of estrogen, produced by the ovarian follicle
A form of the hormone estrogen.
The potent form of the female hormone, estrogen, which is produced by granulosa cells of the ovary. The follicle is seen to increase in fluid content and therefore increase in diameter during treatment with gonadotropins.
Produced by the ovaries, the dominant form of estrogen in premenopausal women.
The principal estrogen produced by the ovary. Responsible for formation of the female secondary sex characteristics such as large breasts; supports the growth of the follicle and the development of the uterine lining. At midcycle the peak estrogen level triggers the release of the LH spike from the pituitary gland. The LH spike is necessary for the release of the ovum from the follicle. Fat cells in both obese men and women can also manufacture estrogen from androgens and interfere with fertility. The blood test to monitor estradiol is E2 - Rapid Assay. Women on injectable fertility drugs have routine E2 monitoring.
The main estrogen hormone produced by the ovary. It is responsible for formation of the female secondary sex characteristics and supports the growth of the follicle and the development of the uterine lining.
The most potent of the naturally occurring estrogens that is administered in its natural or semisynthetic form especially to treat menopausal symptoms. Soybean isoflavones have between 1/1,000 and 1/100,000 the activity of estradiol.
Estradiol (17β-estradiol) (also oestradiol) is a sex hormone. Labelled the "female" hormone but also present in males, it represents the major estrogen in humans. Estradiol has not only a critical impact on reproductive and sexual functioning, but also affects other organs including bone structure.
