This paper presents independent research funded by grants from the MRC, BBSRC, and NIHR and supported by the NIHR/Wellcome Trust Imperial Clinical Research Facility and Imperial Biomedical Research Centre. Conversely, Tan and colleagues randomized patients to trigger either once the lead follicle was 18 mm, or 1 day later, or 2 days later and observed no differences in the number of oocytes retrieved (30). Data for hCG trigger were from a case-series also carried out at My Duc Hospital, Ho Chi Minh City, Vietnam. doi:10.1530/REP-17-0268, Keywords: follicle size, trigger, mature oocyte, IVF treatment, kisspeptin, Citation: Abbara A, Vuong LN, Ho VNA, Clarke SA, Jeffers L, Comninos AN, Salim R, Ho TM, Kelsey TW, Trew GH, Humaidan P and Dhillo WS (2018) Follicle Size on Day of Trigger Most Likely to Yield a Mature Oocyte. Went in today and saw one great follicle 25 mm!!! A follicle will grow 7-8mm a day until it ruptures at somewhere between 18-25mm. Conclusion: Follicles 12–19 mm on the morning of trigger administration were most likely to yield a mature oocyte following hCG, GnRHa, or kisspeptin. Furthermore, delaying triggering until follicles grow to a larger size could also result in an untimely rise in serum progesterone that could prematurely mature the endometrium, resulting in an out of phase endometrium and reduced implantation rates (26). Random forest models can be advantageous over generalized linear regression models if the number of outcome variables is comparatively low compared with the number of predictor variables. Hi happy0, I am 4dpiui. Hum Reprod (2012) 27(8):2373–9. doi:10.1210/jc.2015-2332, 10. Wow, I'm surprised that no one responded. Equivalent results for the relationship between follicle sizes on day of trigger and the number of embryos and grade 1 blastocysts are presented in Table 4 (generalized linear model) and Table 5 (random forest model).

There are so many factors and this is why getting pregnant, whether by IVF or not is such a lottery and such a miracle. Hum Reprod (2016) 31:1383–6. That it's either a cycst (which I'm pretty sure it's not) or the egg is "over mature"?? Scattergram (median and interquartile range) of the number of oocytes (A), mature oocytes (B), and zygotes (C) by the proportion of follicles on the day of trigger within the size range 12–19 mm in patients triggered with either hCG or GnRH agonist. Using the model generated through random forest analysis of patients triggered with hCG or GnRHa, we simulated 1,000 patients having all their follicles within the optimal follicle size range (12–19 mm) and compared these to a further 1,000 simulated patients with all their follicles outside of this size range. However, limited data exist to establish which follicle size on the day of trigger is most likely to yield a mature oocyte. This involved fitting linear models that identify the coefficient of determination (r2) between the number of follicles within a certain size range and the number of mature oocytes retrieved. J Assist Reprod Genet (2014) 31(1):73–7. Most IVF centers will therefore, monitor follicular size and administer the trigger of oocyte maturation once follicles are deemed to have grown to an appropriate size. Objective: To identify follicle sizes on the day of trigger most likely to yield a mature oocyte following hCG, GnRH agonist (GnRHa), or kisspeptin during IVF treatment. Abbara A, Clarke S, Islam R, Prague JK, Comninos AN, Narayanaswamy S, et al. Endocrinol. Patients: Four hundred and forty nine women aged 18–38 years with antral follicle counts 4–87 were triggered with hCG (n = 161), GnRHa (n = 165), or kisspeptin (n = 173). No use, distribution or reproduction is permitted which does not comply with these terms. 25 mm follicle at trigger, 0.25 mm Vegetal pole Blastula (cross section) Animal pole Blasto- coel Blastula (at least 128 cells). Analysis was performed in three stages. Although the contribution was small, several studies have suggested that kisspeptin may have additional direct ovarian effects via ovarian kisspeptin receptors, beyond its predominant mode of action via endogenous GnRH release from the hypothalamus (38–41). I took 100mg of Clomid on days 5-11 of my cycle. doi:10.1016/j.fertnstert.2005.08.033, 21. They categorized Chinese women co-treated with a GnRH antagonist cycles by the proportion of follicles ≥10 mm which were also ≥17 mm on the day of trigger; as low (30% ≥17 mm), middle (30–60% ≥17 mm), or high proportion (>60% ≥17 mm) (3). Statistical analysis was performed using R version 3.3.1; random forest models were derived using the randomForest pckage, and validated using the cforest package, which is designed to identify and correct for potential autocorrelations in the data used. The views expressed are those of the author(s) and not necessarily those of the MRC, BBSRC, the NHS, the NIHR, or the Department of Health. Fertil Steril (1994) 62(6):1205–10. Similarly, Kolibianakis observed that delaying the trigger by 48 h resulted in 1.3 fewer follicles of 11–14 mm and 3.1 more follicles of ≥17 mm with an associated rise in progesterone of 0.4 ng/ml and detrimental effects on pregnancy potential (27). Lan VTN, Linh NK, Tuong HM, Wong PC, Howles CM. Abbara A, Jayasena CN, Christopoulos G, Narayanaswamy S, Izzi-Engbeaya C, Nijher GMK, et al. Patients triggered with hCG were stimulated with follitropin-β daily (dose of 150–300 IU based on AMH level, AFC, age, history of previous response). For kisspeptin, the data were less clear, but significant follicle size categories were in a similar size range. Thus, while similar results were observed for kisspeptin as for other triggers, it is interesting to note that some smaller follicles could also contribute to the number of oocytes retrieved for kisspeptin more so than for other triggers (see Tables 2 and 3). While this is a potential confounder, this would be insufficient to explain the magnitude of increase observed. While, follicles in the center as well as the periphery, are seen in normal induced multicystic ovaries 4. doi:10.1023/A:1022977002954, 38. Salha O, Nugent D, Dada T, Kaufmann S, Levett S, Jenner L, et al. Follicles arranged in the periphery forming a 'necklace sign', echogenic stroma, and more than 10 follicles of less than 9 mm size, signify a polycystic pattern in induced cycle. Looking back at my old notes, the day before trigger the first time, I had 1 18 and 4 17s, but still stimmed one more day. Does this seem a bit early or am i paranoid? As this study was a non-interventional analysis and triggering was carried out once two to three ovarian follicles reached ≥17–18 mm in diameter as per routine unit protocols, there were fewer follicles at larger sizes in this study. Kisspeptin across the human lifespan: evidence from animal studies and beyond. GnRHa data were from a randomized controlled trial and hCG data from a case-series conducted at My Duc Hospital, Ho Chi Minh City, Vietnam (10). IUI took place on day 15. J Ovarian Res (2014) 7:77. doi:10.1186/1757-2215-7-77, 7. It is widely accepted that ovarian follicles that are “too small” are less likely to respond suitably to trigger administration and yield a mature oocyte (1). Importantly, there was not a significant difference in the total number of follicles in the one group compared with the other group (20.9 follicles vs 19.3 follicles, P = 0.17) to account for this difference. The IUI is scheduled 36 hours after the trigger medication is injected. Son WY, Chung JT, Dahan M, Reinblatt S, Tan SL, Holzer H. Comparison of fertilization and embryonic development in sibling in vivo matured oocytes retrieved from different sizes follicles from in vitro maturation cycles. Fertil Steril (2011) 96(5):1112–5. Random forest models also make no assumptions regarding linearity or parametric distributions in the data analyzed (and thus are less reliant on appropriate data transformation) and promote model variance by repeated sampling of the data.

Prolongation of the follicular phase in in vitro fertilization results in a lower ongoing pregnancy rate in cycles stimulated with recombinant follicle-stimulating hormone and gonadotropin-releasing hormone antagonists. Nelder JA, Wedderburn RWM. doi:10.1016/j.fertnstert.2007.02.011, 24. Overall, follicles of 16–22 mm on the day of oocyte retrieval are more likely to contain mature oocytes than smaller follicles, while larger follicles are more likely to contain post-mature oocytes (1). Went in for a second opinion ultrasound on CD16 and a 15mm follicle showed up! Rosen MP, Shen S, Dobson AT, Rinaudo PF, McCulloch CE, Cedars MI. J R Stat Soc Ser A (1972) 135(3):370. doi:10.2307/2344614, 17. Saadeldin IM, Koo OJ, Kang JT, Kwon DK, Park SJ, Kim SJ, et al. Consequently, we investigated whether patients having a greater proportion of their follicles within the size range 12–19 mm on the day of trigger were likely to retrieve more oocytes than patients with the smallest proportion of follicles within this follicles size range. Drug-induced immunosuppression in ABD (e.g. In the ovaries of the female reproductive system, an ovarian follicle is a fluid-filled sac that contains an immature egg, or oocyte. However, a simple linear model compares the number of follicles in each size category with the number of mature oocytes retrieved in isolation. More than one statistical approach was used to increase confidence that the data allowed accurate determination of optimal follicle size on day of trigger. Gynecol Endocrinol (2014) 30(6):431–7. Data for GnRHa were obtained from a randomized controlled trial of triptorelin dose 0.2–0.4 mg conducted at My Duc Hospital, Ho Chi Minh City, Vietnam. As follicles increase beyond a certain size, they are more likely to yield post-mature oocytes. doi:10.1210/en.2006-0117, 39. This provided initial confirmation that the number of follicles of different size ranges was associated with the number of mature oocytes retrieved following each trigger. Comparing the 50% of patients with the highest proportion of their follicles within the size range 12–19 mm with the 50% with the lowest proportions in this range revealed an increase in the number of oocytes of 3.6 oocytes and 3.3 mature oocytes (P < 0.0001) for hCG and 3.9 oocytes and 2.5 mature oocytes (P < 0.01) for GnRHa triggering. doi:10.1016/j.fertnstert.2011.08.029, 29. One of the most widely applied protocols is administering the trigger when several follicles have reached a diameter of ≥ 18 mm 1-6. Effect of kisspeptin on in vitro maturation of sheep oocytes. Reply Quote. Levy G, Hill MJ, Ramirez CI, Correa L, Ryan ME, DeCherney AH, et al. Hence, the more robust approach of generalized linear regression was used (16), allowing identification of the follicle size on the day of trigger with the greatest contribution to the number of mature oocytes retrieved, when compared with all other follicle size categories.

Growth rates of ovarian follicles during natural menstrual cycles, oral contraception cycles, and ovarian stimulation cycles. For these patients, the highest coefficient of determination for the number of oocytes retrieved was for follicle size category 9–14 mm r2 0.478 (P < 0.0001), and for the number of mature oocytes also for follicle size category 9–14 mm r2 0.444 (P < 0.0001). Hum Reprod (1997) 12(9):2002–5. A quantitative assessment of follicle size on oocyte developmental competence. Trigger shots cause ovulation in 48 hours so they have to be given at a certain time. The second time, I had 2 17s the day before trigger, so I can definitely see why she had me wait. Neumann K, Griesinger G. Follicular flushing in patients with poor ovarian response: a systematic review and meta-analysis. doi:10.1093/humrep/12.9.2002, 3. Overall, follicles of 16–22 mm on the day of oocyte retrieval are more likely to contain mature oocytes than smaller follicles, while larger follicles are more likely to contain post-mature oocytes (1). Data were obtained from patients undergoing clinical trials at Hammersmith Hospital, London. Fertil Steril (2016) 105(2):356–63. Sizing follicles was carried out during ultrasound assessment.

Fertil Steril (1995) 64(4):787–90. PH and WD take final responsibility for this article. Follies grow 2 mm a day. For the hCG case-series, the IRB reference number was NCKH/CGRH_09_2017, ethical approval reference number: 10/17/DD-BVMD, and ClinicalTrials.gov Identifier: NCT03174691. Kisspeptin data were obtained from patients undergoing clinical trials at Hammersmith Hospital, London (9, 11, 12). Because of unequal cell division due to the large amount of yolk in the vegetal hemisphere, the blastocoel is located in the animal hemisphere, as In that study, oocyte maturation rate rose from 75.3% from follicles < 16 mm, to 85.9% of follicles 16–23 mm, to 95.3% of follicle size > 23 mm (2). Ovarian kisspeptin expression was undetectable in immature oocytes, but increased at ovulation (38). Ideal size for a follicle is between 18mm and 24mm. Fertil Steril (2011) 95(2):826–8. Shapiro BS, Daneshmand ST, Restrepo H, Garner FC, Aguirre M, Hudson C, et al. It is widely accepted that ovarian follicles that are “too small” are less likely to respond suitably to trigger administration and yield a mature oocyte (1). IVF treatment involves the administration of supra-physiological doses of follicle-stimulating hormone (FSH) to induce the growth of multiple ovarian follicles. Importantly, knowledge of the size of follicles on day of trigger from which one could reasonably expect to retrieve a mature oocyte could enable the accurate determination of trigger efficacy. As cleavage continues, a fluid-filled cavity, the blastocoel, forms within the embryo. For kisspeptin-triggered cycles, transvaginal ultrasonographic measurement (Toshiba Xario Prime, Crawley, UK) of follicle size was conducted by up to nine experienced IVF physicians/ultrasonographers at Hammersmith IVF unit over the 3-year study period. Fertil Steril (2006) 85(3):578–83. This causes the oocytes to mature in a similar way to the way they would in a natural cycle. Patients triggered with GnRHa were stimulated, using a depot injection of 100–150 IU of corifollitropin alfa (Elonva; Merck Sharp & Dohme, UK) from cycle day 2, followed by co-treatment with ganirelix (Merck Sharp & Dohme B.V., Germany) (starting on day 5 after stimulation) and follitropin-β.

Hu X, Luo Y, Huang K, Li Y, Xu Y, Zhou C, et al. Clarke SA, Dhillo WS. Objective: To determine the optimal size of the leading follicle before human chorionic gonadotropin (hCG) administration in cycles with clomiphene citrate (CC) and letrozole, and to examine any differences in the optimal leading follicle size between cycles with CC and letrozole. Front. doi:10.1071/RD11118, 41. Went in for ultrasound on CD13 and showed no mature follicles. This is consistent with the current literature which suggests that follicles of sizes 16–22 mm on the day of oocyte retrieval (measured 2 days later) contribute the most to the number of oocytes retrieved (1). Abbara A, Islam R, Clarke SA, Jeffers L, Christopoulos G, Comninos AN, et al. However, the 25 mm follicle is large and the egg within it might be over-mature. Data were collected by AA, LV, VH, TK, SC, LJ, AC, and TH. Exclusion criteria: polycystic ovary syndrome, chronic medical condition, participating in another clinical trial or use of LH/FSH preparations prior to the study. Paradoxical effects of kisspeptin: it enhances oocyte in vitro maturation but has an adverse impact on hatched blastocysts during in vitro culture. One could speculate that in addition to the size of follicles, the duration at which larger follicles are present before trigger administration and whether effective GnRH antagonism has been achieved could also contribute to the degree of premature progesterone elevation. All follicles that were visible on ultrasound and ≥8 mm in diameter were aspirated at oocyte retrieval. Initially, standard linear regression of number of follicles of different size categories on day of trigger and outcomes (number of mature oocytes collected) was performed. doi:10.1093/humrep/deq059, 32. Here are the most important contributions of each author: AA, LV, RS, TK, GT, PH, and WD designed the study. doi:10.1016/j.fertnstert.2004.01.027, 28. doi:10.1016/S0015-0282(16)57186-6, 22. Other authors have reported both number of follicles ≥14 mm and the number of follicles ≥10 mm to allow the reader to account for different estimations of oocyte yield (6).

Gonadotropin-releasing hormone agonist trigger in oocyte donors co-treated with a gonadotropin-releasing hormone antagonist: a dose-finding study. In addition, we recommend that these analyses be re-conducted in data sets obtained from different centers with the possibility of different stimulation protocols or study populations to confirm the results from this study. Endocrinology (2006) 147(10):4852–62. Women were aged 18–38 years with a body mass index (BMI) 18–29 kg/m2 and had antral follicle counts 4–87. doi:10.1016/j.fertnstert.2010.09.009, 6. This medication is an injection with a small needle in the abdomen. Furthermore, delaying triggering could result in more follicles > 19 mm which in turn could increase the risk of premature rise in serum progesterone (see Figure 2). It happens around 25-28 mm. However, Ectors et al. observed that the odds of retrieving mature oocytes from follicles of 13–15 mm on the day of oocyte retrieval were 70% less compared with follicles > 18 mm (23). First-pass analysis using simple linear regression of the number of oocytes retrieved vs the number of follicles on day of trigger in each category of follicle size determined that the highest coefficient of determination to be at follicle size category 12–17 mm for hCG r2 0.433 (P < 0.0001); 10–14 mm for GnRHa r2 0.512 (P < 0.0001); and 7–18 mm for kisspeptin r2 0.246 (P < 0.0001). Inclusion criteria: age 18–38 years, BMI < 28 kg/m2, normal ovarian reserve: AMH > 1.25 ng/ml (8.93 pmol/l) or AFC ≥6 (13). doi:10.1016/j.fertnstert.2006.11.069, 5. Reprod Fertil Dev (2012) 24(5):656–68. Furthermore, once ovarian follicles grow too large, follicles may contain oocytes that are “post-mature” and also not competent for fertilization (2). Is it possible that the follicle grew to 15mm over the … The regression coefficient (r2) for the generalized linear regression model to determine the number of oocytes retrieved for GnRHa was 0.56 for oocytes and 0.64 for number of mature oocytes retrieved. Table 4. Kisspeptin-54 triggers egg maturation in women undergoing in vitro fertilization. During ovulation, a mature egg is released from a follicle.While several follicles begin to develop each cycle, normally only one will ovulate an egg (rarely, more than one egg is released, increasing the potential for twins). Tan S-L, Balen A, Hussein EE, Mills C, Campbell S, Yovich J, et al. Mach Learn (2001) 45(1):5–32. With injection meds, it's around the same as normal ovulation. Setting: HCG and GnRHa data were collected at My Duc Hospital, Ho Chi Minh City, Vietnam, and kisspeptin data were collected at Hammersmith Hospital, London, UK. Estimating the net effect of progesterone elevation on the day of hCG on live birth rates after IVF: a cohort analysis of 3296 IVF cycles. Medicine (Baltimore) (2016) 95(20):e3691. Byri P, Gangineni A, Reddy KR, Raghavender KBP. I feel we involve so much in tests and doc instructions and not doing what we have to do. The corifollitropin alfa dose used for stimulation was either 100 or 150 µg, depending on body weight, and the corresponding follitropin-β dose was 150 or 200 IU/day, starting from day 8 of simulation until the day of triggering. doi:10.1093/humrep/dex253, 13. Go by ur RE advise but do BD from day 10 u know ? Inclusion criteria: aged 18–34 years, BMI 18–29 kg/m2, early follicular FSH ≤12 IU/l, serum AMH ≥10 pmol/l (≥1.4 ng/ml), both ovaries intact. observed that follicles with a volume < 1 ml (~12.4 mm) and >7 ml (~23.7 mm) had a statistically lower oocyte yield (59%) when compared with those between 1 and 7 ml (~74–85%) (21). doi:10.1016/j.fertnstert.2015.10.014, 11. In this study, we observe that pre-trigger serum progesterone was more likely to be elevated if there were a greater number of larger follicles (≥19 mm) on the day of trigger (see Figure 2). doi:10.1093/humrep/der048, 30. Trials of hCG was supported through a local departmental fund. *Correspondence: Waljit S. Dhillo, w.dhillo@imperial.ac.uk, Front. We determine that follicles of 12–19 mm on the day of trigger administration had the greatest contribution to the number of oocytes retrieved. Figure 2. Kisspeptin has only recently been investigated as a trigger of oocyte maturation since 2014; consequently, data from the kisspeptin trials may have incorporated doses which were suboptimal for oocyte maturation. It is less invasive than other assisted reproductive treatment (ART) procedures, requiring less laboratory commitment and regulation (Homburg, 2003; van Santbrink and Fauser, 2003). Furthermore, simple linear models are susceptible to “autocorrelation,” whereby the number of follicles in one size category may also be included in other size categories. Similarly, the number of oocytes, mature oocytes, and zygotes, was greater by the proportion of follicles within the follicles size range 12–19 mm on day of trigger for patients triggered with either hCG or GnRHa (see Figure 1). Efficacy of kisspeptin-54 to trigger oocyte maturation in women at high risk of ovarian hyperstimulation syndrome (OHSS) during in vitro fertilization (IVF) therapy. Hello I'm 40 and trying ivf for the 1st x, on lupron n hmg went 2day n only 1 follicle waiting 4 dr 2 call me 2 c Wuts da nex step. A meta-analysis by Chen et al. The trigger kisspeptin-54 (6.4–12.8 nmol/kg as a single subcutaneous bolus or 19.2 nmol/kg as a split bolus over 10 h, Bachem Holding AG, Bubendorf, Switzerland) was administered once three follicles reached ≥18 mm in diameter (9, 11, 12). This was consistent with the work of Dubey and colleagues, whereby 85% of oocytes were collected from follicles of 14–24 mm at the time of oocyte retrieval (22). with methotrexate) was considered a prospective triggering factor for lymphoproliferative disorders [ 132 ]. Impact Factor 3.644 | CiteScore 3.4More on impact ›, Oregon Health and Science University, United States. ), estrogen 17,969 2 days before trigger … Similarly, Tremellen and Lane found that patients with “ideal” timing of the hCG trigger (defined as ≥2 follicles of ≥17 mm, with the majority of follicles ≥14 mm) had similar outcomes to patients triggered either a day earlier or later (31), whereas Vandekerckhove et al. doi:10.1111/cen.13569, 9. She said that 27 was a good size for concieving. Lessons on the size of follicle from which mature oocytes can be retrieved can also be learned from studies of in vitro maturation (IVM) (34).

Data from GnRHa triggered IVF cycles were obtained from a single-center randomized controlled trial conducted at My Duc Hospital, Ho Chi Minh City, Vietnam (11). Follicles as small as 4 mm have been found to contain mature oocytes, and mature oocytes from follicles ≤10 mm following hCG priming resulted in similar outcomes compared with those retrieved from larger follicles (35). J Endocrinol (2016) 229(3):R83–98. Reprod Biol Endocrinol (2014) 12:107. doi:10.1186/1477-7827-12-107, PubMed Abstract | CrossRef Full Text | Google Scholar, 2. Clin Endocrinol (Oxf) (2018).

PH declares unrestricted research grants from MSD, Merck and Ferring as well as honoraria for lectures from MSD, Merck and Finox. The trigger (either recombinant hCG 250 µg equivalent to 6,500 IU, or GnRHa triptorelin 0.2–0.4 mg) was administered as soon as two follicles reached a size of ≥17 mm. However, patients receiving GnRHa had a greater number of follicles on the day of trigger (GnRHa 34.2 follicles; hCG 21.7 follicles) making it difficult to accurately compare trigger efficacy between the two groups (4). Wittmaack et al. Fertil Steril (2007) 88(1):237–9. Trial of GnRHa was sponsored by Merck Sharp & Dohme (grant number IIS 52023). Table 2. Fresh embryo transfer was not carried out in GnRHa- or hCG-triggered cycles. A generalized linear regression model was used to determine the sizes of follicles on the day of trigger contributing most to the number of oocytes and mature oocytes retrieved (see Table 2). The current method of determining the day of trigger administration once two to three lead follicles are 17–18 mm in size should lead to a similar day of trigger as most follicles will still be within the size range 12–19 mm.

Relationship of human follicular diameter with oocyte fertilization and development after in-vitro fertilization or intracytoplasmic sperm injection. Full details of the IVF protocols used for the GnRHa study (10) and the kisspeptin study (9, 11, 12) have previously been reported. Using simulated follicle size profiles of patients with 20 follicles on the day of trigger, our model predicts that the number of oocytes retrieved would increase from a mean 9.8 (95% prediction limit 9.3–10.3) to 14.8 (95% prediction limit 13.3–16.3) oocytes due to the difference in follicle size profile alone. Commensurate with this, Castellano observed that kisspeptin expression increased in a cyclical manner during the menstrual cycle of a rodent model, predominantly localized to the theca layer of growing follicles and the corpora lutea (38). However, limited data exist to establish which follicle size on the day of trigger is most likely to yield a mature oocyte. Fertil Steril (1992) 57(6):1259–64.
