Despite this low number, On Day 5 of stimulation, estradiol levels can range from, On Day 6 of stimulation, estradiol levels can range from, On Day 7 of stimulation, estradiol levels can range from, On Day 11 of stimulation (which is near the higher end of how long an IVF cycle can go) estradiol levels can range from. High estrogen levels can cause symptoms such as irregular or heavy periods, weight gain, fatigue, and fibroids in females. 
In case the estrogen levels drop unexpectedly before egg retrieval, this can be a bad sign.

If you are concerend about your hormone health, taking a test or consulting a medical expert are sure ways of identifying issues. The currently available results are contradictory as progesterone levels >20 ng/ml (possibly due to an escape ovulation and subsequent embryo-endometrial asynchrony) on the day of transfer have been associated with decreased ongoing pregnancy and live birth rates (Kofinas et al., 2015), while an optimal mid-luteal progesterone range between 22 and 31 ng/ml has also been proposed (Yovich et al., 2015). Estrogen is partly responsible for creating healthy sperm. In general, you can expect each mature follicle to produce ~200-300 pg/mL of estradiol. That cycle failed. However in HRT FET cycles, as no corpus luteum and, hence, no endogenous progesterone productionis present, the best moment remains to be elucidated. You should not rely solely on this information. As for the optimal progesterone dose specifically in HRT FET cycles, one retrospective study concluded that doubling the dose of vaginal progesterone gel in patients with oligomenorrhoea significantly increased live birth rates (Alsbjerg et al., 2013). Clinical practice proposal for embryo transfer timing in the different preparation methods. The three groups were then classified even further into. If you are concerned about your own or someone else's hormone health, a home hormone test could help identify health issues that might affect a woman's ability to conceive. 
WebI don't think this hCG is too high, I think I read reports of hCG being more than 100,000 for Down syndrome or molar. This will mean there are no embryos to transfer. What is the optimal endometrial preparation protocol for a frozen embryo transfer (FET)? eCollection Thin endometrium in donor oocyte recipients: enigma or obstacle for implantation? Progesterone rises slightly to 13 ng/ml even 12 h to 3 days prior to ovulation, due to the LH-stimulated production by the peripheral granulosa cells (Hoff et al., 1983), with a steep increase in production following ovulation (310 ng/ml) due to production by the corpus luteum. One could draw the parallel to FET and transfer 1-day earlier when a spontaneous LH surge is detected in the serum compared to when ovulation is triggered with hCG. The number of high quality randomized controlled trials (RCTs) is scarce and, hence, the evidence for the best protocol for FET is poor.

In the following review, we gather the available evidence in search for the best preparation protocol for FET. The estimated onset of placental steroidogenesis, the so-called luteoplacental shift, occurs during the fifth gestational week (Scott et al., 1991a). The frozen-embryo transfer (FET) has been largely promoted and accounted for 26% of all in vitro fertilization (IVF) cycles. A recent RCT compared the outcomes of blastocyst transfer with either 5 or 7 days of progesterone supplementation and CPRs once more tended to be in favor of the shorter protocol, although not statistically significant (32.5% versus 27.6%) (van de Vijver et al., 2017).

What is the optimal duration of progesterone administration before transferring a vitrified-warmed cleavage stage embryo? Though some studies have reported increased D14 TSH after fresh ET, few studies have focused on the impact of D14 TSH after frozen-thawed embryo transfer (FET) on clinical outcomes, the ideal D14 TSH after FET, whether this parameter matters for clinical outcomes.

In general, your estradiol should increase regularly until it reaches its peak value, which is usually between 1,000 to 4,000 pg/mL in most patients. We suggest not to administer hCG when a spontaneous LH surge is detected, given the previously noted potential association with a detrimental outcome (Fatemi et al., 2010), even though it has not been confirmed in a recent post hoc analysis of the ANTARCTICA trial (Groenewoud et al., 2017).

MTgYw3P:c^CGeuKrA~Qgi% c It is generally considered that once progesterone levels reach a critical threshold, they set into motion a well-timed and orderly secretory transformation of the endometrium leading to receptivity (Franasiak et al., 2016). The use of an antagonist protocol with agonist triggering followed by a freeze-all strategy and transfer of the embryo(s) in a subsequent FET cycle is a promising option with high live birth rates (Blockeel et al., 2016).

Dr. Jay Nemiro answered Fertility Medicine 46 years experience Not sure: Generally, nine days after an embryo transfer, you draw your blood for a HCG level. Unexpected dropping estrogen levels: Some IVF protocols do have an expected drop in estrogen prior to the egg retrieval stage. A difference in the timing of FET in true versus modified NC could be considered, as ovulation occurs 3648 h after hCG administration but varies from 24 to 56 h after a spontaneous LH surge (Kosmas et al., 2007). Furthermore, another potential confounding factor is intercourse during a FET cycle, since it has been shown that it significantly reduces serum progesterone levels in women administering vaginal progesterone gel (Merriam et al., 2015). Are There Other Side Effects Of High Estrogen Levels? A previous retrospective analysis has shown a higher miscarriage rate for HRT compared to NC FET, although this could be related to the higher proportion of polycystic ovary syndrome patients in the HRT group (Toms et al., 2012).

MTgYw3P:c^CGeuKrA~Qgi% c It is generally considered that once progesterone levels reach a critical threshold, they set into motion a well-timed and orderly secretory transformation of the endometrium leading to receptivity (Franasiak et al., 2016). The use of an antagonist protocol with agonist triggering followed by a freeze-all strategy and transfer of the embryo(s) in a subsequent FET cycle is a promising option with high live birth rates (Blockeel et al., 2016). It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide, This PDF is available to Subscribers Only.

Dr. Jay Nemiro answered Fertility Medicine 46 years experience Not sure: Generally, nine days after an embryo transfer, you draw your blood for a HCG level. Unexpected dropping estrogen levels: Some IVF protocols do have an expected drop in estrogen prior to the egg retrieval stage. A difference in the timing of FET in true versus modified NC could be considered, as ovulation occurs 3648 h after hCG administration but varies from 24 to 56 h after a spontaneous LH surge (Kosmas et al., 2007). Furthermore, another potential confounding factor is intercourse during a FET cycle, since it has been shown that it significantly reduces serum progesterone levels in women administering vaginal progesterone gel (Merriam et al., 2015). Are There Other Side Effects Of High Estrogen Levels? A previous retrospective analysis has shown a higher miscarriage rate for HRT compared to NC FET, although this could be related to the higher proportion of polycystic ovary syndrome patients in the HRT group (Toms et al., 2012).
