Retrospective data have left physicians with conflicting information in terms of clinical outcome (Ghobara and Vandekerckhove, 2008; Givens et al., 2009; Chang et al., 2011; Groenewoud et al., 2013; Guan et al., 2016).

The actual value of your estradiol (E2) during IVF isnt as important as the overall trend and the number of ovarian follicles you have growing.

What is the ideal duration of progesterone supplementation before the transfer of cryopreserved-thawed embryos in estrogen/progesterone replacement protocols? Low estradiol responses in oocyte donors undergoing gonadotropin stimulation do not influence clinical outcomes.

Your email address will not be published. Does a frozen embryo transfer ameliorate the effect of elevated progesterone seen in fresh transfer cycles? 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). If you have two follicles growing, your estradiol level might be between 300-600 pg/mL at its peak. This is a more common practice for logistical reasons and because this method is more likely to result in a live birth. is responsible for the concept and final revision of the manuscript. H.T.

In the artificial cycle, also referred to as a HRT cycle, endometrial proliferation and follicular growth suppression is achieved by estrogen supplementation. These anovulatory cycles are most common among women between the ages of 30 and 50 and in women with secondary conditions which affect ovulation, such as polycystic ovary syndrome and endometriosis.

You may have several emotions as you prepare for, start, and complete an IVF cycle. In current daily practice, different FET preparation methods and timing strategies are used.

Previous observational studies have highlighted the negative effects of serum hormone levels at the minimum threshold during frozen embryo transfer (FET) cycles. The standard dose of estradiol valerate is 6 mg daily (Cobo et al., 2012), although different step up protocolsmimicking the rising estradiol levels of a NCare also frequently used (Soares et al., 2005; Escrib et al., 2006; van de Vijver et al., 2014). Finally, luteal phase support (LPS) was given only in the RCT performed by Weissman et al.

Hence, future research should compare both the pregnancy and neonatal outcomes between HRT and true NC FET. Currently 29 weeks, passed all screening tests and fetal heart echo and anatomy so far! That cycle failed. . We hypothesize that hCG trigger, as well as additional LPS may impact on the natural course of the endometrium towards receptivity and might cause a shift in the WOI, leading to a more pronounced embryo-endometrial asynchrony. When using urinary LH measurement, this difference in timing might not be beneficial, since a 1-day delay for the detection of peak hormone levels in the urine has been described (Cekan et al., 1986).

Given that the WOI is limited in time, this detection of an optimal period is unsurprising and easily understandable; implantation is possible in a quite broad window, but only optimal in a narrower timeframe (Franasiak et al., 2016). However, an impact has been described of the method of freezing on post-thaw embryo development and metabolism (Balaban et al., 2008; Cercas et al., 2012) and further research into the potential clinical effects of such differences might optimize embryo-endometrial synchrony.

Although the serum hormone levels in such cases are often exhaustively assessed (Casper et al., 2016), the role of such endocrine monitoring in addition to the usual ultrasound monitoring is a subject of much debate in both true and modified NC FETs (Groenewoud et al., 2012, 2017; Lee et al., 2014).

Objective: To explore whether a high serum estradiol (E2) level before progesterone administration adversely affects the pregnancy outcomes of frozen-thawed embryo transfer (FET) cycles.

Another retrospective study investigating true NC FET LPS by two IM injections of hCG (the day of FET and 6 days later) failed to show any difference in outcome (Lee et al., 2013). Furthermore, the definition of what constitutes an LH surge is not unanimous.

Estrogen is released by granulosa cells in growing follicles. In one randomized controlled trial (RCT), the use of such an approach was associated with increased clinical pregnancy and live birth rates, mainly due to lower cycle cancellation rates (El-Toukhy et al., 2004). No consensus has been reached yet on when to stop progesterone administration following a positive pregnancy test in HRT FET.

Although the optimal endometrial preparation protocol for FET needs further research and is yet to be determined, we propose a standardized timing strategy based on the current available evidence which could assist in the harmonization and comparability of clinic practice and future trials. endstream endobj 198 0 obj <>>>/Filter/Standard/Length 128/O(R3UfV=T;in)/P -1324/R 4/StmF/StdCF/StrF/StdCF/U(n84h' )/V 4>> endobj 199 0 obj <>/Metadata 13 0 R/PageLayout/OneColumn/Pages 195 0 R/StructTreeRoot 23 0 R/Type/Catalog>> endobj 200 0 obj <>/ExtGState<>/Font<>/XObject<>>>/Rotate 0/StructParents 0/Type/Page>> endobj 201 0 obj <>stream One of the posited reasons for this difference was that the research groups had considered different timings to perform the embryo transfer (specifically, a 1-day difference between both studies).

Conclusion: Outcomes of FET cycles were similar between a The number of high quality randomized controlled trials (RCTs) is scarce and, hence, the evidence for the best protocol for FET is poor. and C.B. WebIt is possible to get pregnant if you are living with high estrogen levels, however, there is an increased likelihood of fertility issues in those who are living with estrogen A complete lack of ovulation (and periods). The prevalence of a luteal phase defect in NCs in normo-ovulatory subfertility patients has been historically described to be around 8% (Rosenberg et al., 1980), with mid-luteal serum progesterone levels <10 ng/ml being considered to reflect a NC luteal phase defect (Jordan et al., 1994).

If your estrogen levels are under 200 near the end of a stimulation, it is possible that you dont have any mature eggs developing. Our retrospective analysis (Montagut et al., 2016) did not show a significant difference in CPR when comparing true NC FET with or without MVP; on the contrary, there was a trend favouring one not to supplement (CPR 46.9% versus 39.9%). [] The main impact factors of FET are embryo quality, number of transferred embryos and endometrial receptivity. A randomized controlled trial, High and low BMI increase the risk of miscarriage after IVF/ICSI and FET, Spontaneous ovulation versus HCG triggering for timing natural-cycle frozen-thawed embryo transfer: a randomized study. A.V.D.V., A.R., L.V.L. Hormonal imbalances including estrogen dominance are often responsible for fertility issues couples may face when trying to get pregnant. The goal of fertility-sparing treatment (FST) for patients desiring future fertility with EMCA, and its precursor EH, is to clear the affected tissue and revert to normal endometrial function. Furthermore, the costs of both treatment modalities were comparable.

Retrospective data are conflicting, being in favor of the IM route (Haddad et al., 2007; Kaser et al., 2012) or showing no significant differences in terms of outcome (Shapiro et al., 2014). Caution, however, is warranted, given that a higher miscarriage rate with shorter estrogen supplementation has also been previously reported (Borini et al., 2001).

On the contrary, if you develop high estrogen levels in your cycle, be sure to follow closely with your fertility doctor to discuss OHSS risk mitigation.

Estrogens may be administered orally, vaginally and parentally (transdermal route) and both natural as well as synthetic estrogens may be used (Scott et al., 1991b). 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). The actual level can range from as low as 20 pg/mL to as high as >100 pg/mL on Day 3. a Day 5 embryo on LH + 6). At the basic research level, the evidence points toward the NC being superior to HRT. 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).
