What is the connection between estradiol and pregnancy?
estradiol, also called E2, is a type of estrogen that is released by the ovaries in different amounts during the menstrual cycle. Too large amounts of this sexual hormone can lead to infertility because it can cause ovarian reserve problems, and therefore some contraceptive pills use estradiol to help prevent pregnancy. Like other female sex hormones, estradiol and pregnancy are connected. Women struggling with infertility can let estradiol level test, usually at the same time as screening on follicles stimulating hormone (FSH).
E2 is often considered the most important type of estrogen because it plays a major role in ovulation. At the beginning of the menstrual cycle, the level of estradiol is consistent, but in the middle of the cycle increases sharply. At about the same time, the level of the luteinizing hormone (LH) increases, leading to ovulation. When ovulation is over, the level of estradiol decreases just to increase again when Thormy e corpus luteum.For this reason, estradiol and pregnancy are said to be closely relative because it is not possible to conceive without ovulation.
women who have long tried to conceive could do tests to determine the reasons for infertility. One of the most common projections measures the amount of estradiol, which can determine whether the ovarian reserve is sufficient to achieve pregnancy. In many cases, this test is performed at the same time as the FSH test, which controls extremely low or high levels of stimulating hormone stimulating follicles to determine the reasons for infertility or menstrual irregularities. Both tests are usually performed on the third day of the menstrual cycle and often consist of blood. The results are usually available one day after screening.
In some cases, women who are in the early stages of pregnancy are undergoing a estradiol test to ensure that the placenta and the fetus are properlyThey develop. This is because it is assumed that estradiol and pregnancy are related to the fact that the hormone increases blood flow to the uterus and stimulates breast growth. In addition, it is assumed that estradiol will soften the uterine cervix during pregnancy, allowing birth.
On the other hand, a connection between estradiol and pregnancy sometimes uses to prevent conception. Many hormonal contraceptive pills contain the derivative of this hormone to avoid ovulation because high levels of estradiol often prevent ovulation. Pills that contain this hormone also usually have a progestin that can further inhibit ovulation. Thus, the relationship between estradiol and pregnancy can be used to help or prevent fertility.
