To determine estradiol and estrogen - are the same or not, need to know what is meant by these concepts. Estrogen is a group of hormones that are responsible for a safe pregnancy. Estradiol is one of the 3 major substances belonging to this subclass.
What is estrogen
Under this concept refers to a group of hormones that are responsible for the conception and the normal development of the fetus.
Their activities affect the availability of sexual characteristics, release of an egg in the reproductive organs, the development of the mammary glands.
Estrogen and progesterone, estradiol together with help to keep the fruit healthy, and make childbirth safer and less painful.
types of estrogen
Substances produced by the ovaries, placenta, adrenal gland, liver, adipose tissue and the interaction determine the basis of hormonal levels. There are 3 types of estrogens: estrone, estriol, estradiol. Accurate data on their standards not shown differ from each other in each phase of the cycle.
estrone
Hormone synthesis begins in adolescence and ceases to affect the female body during menopause. Estrone is needed for a full course of menstruation and conception. After exposure to particular enzymes produced therefrom estriol and estradiol.
He is responsible for the formation of the distinctive features of the body structure between men and women, the quality of sex life, stimulation of cervical mucus before ovulation, the correct formation of the uterus. During menopause the amount increases and the estradiol level is reduced to 0.
The norm in the blood depends on the phase of the cycle:
- Follicular - 138.0 pg / ml.
- Ovulatory - 229.0 pg / ml.
- Luteal - 114.0 pg / ml.
- Postmenopause - 103.0 pg / ml.
hormone level can be seen after the date of enzyme immunoassay. He is appointed for suspected infertility, primary and secondary amenorrhea, dysmenorrhea, oligomenorrhea.
Data on estrone help assign treatment in violation of puberty and planning in vitro fertilization.
Estrone is synthesized from derivatives of progesterone in the liver or peripheral tissues. A hormone produced in both sexes and is an intermediate for the synthesis of estradiol. Its level is dependent on the rate of metabolism: the lower it is, the higher the content of estrone.
theelol
One of the 3 hormone which has the lowest biological activity, mainly formed during pregnancy. The normal level of substance promotes mammary increases movement of blood through the vessels, to prevent the appearance of abnormalities in the fetus. It is also involved in the biochemical processes and affects the operation of enzyme systems.
blood levels of trimester:
- Origin - 0,45-3,42 nmol / l.
- Second - 8,0-30,0 nmol / l.
- Third - 25,0-42,0 nmol / L.
Analysis of free estriol designate all future new mothers. The study helps to identify structural abnormalities of the fetus. Particular attention is paid estriol indicators during the prolific conception and the beautiful half of humanity, who bears a child after 35 years.
estradiol
HGH is considered one of the major estrogen, appears in adolescence, the effect on the body ends at the beginning of menopause. Its functions are responsible for most of the reactions occurring in the body:
- It provides the optimal level of cholesterol.
- Responsible for the cardiovascular system.
- It affects blood clotting.
- It forms a favorable environment for the follicular maturation.
- It contributes to the proper development of the embryo.
And estriol and estradiol are fully responsible for the quality of the process of conception and birth. The second hormone affects the appearance of the girls and the state of intimate life. Its rate is determined menstrual cycle phase.
What's the Difference
Estrogen - a subclass of steroid female hormones, there are more than 30, the most important are 3 major described substances. The difference with the estradiol is that the latter is part of a subclass of estrogen. Estrone and estradiol are produced in both sexes; unlike estriol from them - it is synthesized in the body only during pregnancy.
