After a woman decides to undergo in vitro fertilization (IVF), the most crucial step is to induce ovulation. Once the egg is mature, it is then retrieved through artificial selection and successful in vitro fertilization with sperm before being transplanted back into the female uterus to continue the pregnancy. Generally, women need to observe their estrogen levels before retrieving the egg. If the levels are abnormal, it can have an impact. So, how much estrogen is normal for IVF egg retrieval?
When women undergo ovulation induction, the level of estrogen plays a crucial role in observing their body. Abnormal estrogen levels, such as high or low estrogen levels, may indicate poor follicle development. Generally, the normal level of estrogen in women should be between 48 and 521 picomoles per liter during the pre ovulation period, between 70 and 1835 picomoles per liter during ovulation, and then decrease to 272 to 793 picomoles per liter after ovulation.
The normal level of estrogen in most women is maintained at around 300 picomoles per liter. In addition, high blood lipids also indicate more follicles, while low follicles indicate lower blood lipids. In fact, the level of estrogen in women during ovulation induction is not an important measure, but mainly depends on the number and quality of follicles in the ovaries. Therefore, doctors will conduct examinations before women undergo in vitro egg retrieval surgery. Only when the number and quality of follicles meet the requirements will egg retrieval surgery be performed.
Due to the completely different physical constitution of each woman, the specific ovulation promotion plan implemented by doctors will also be different. In addition, the number of follicles obtained from different ovarian functions is also different, so the value of estrogen is also different. If the estrogen level is relatively high during ovulation induction, it may be due to consistent ovulation induction of several follicles.
