12 mm follicle at trigger

s. StickyB. Posted 1/22/13. So I went to the doctor yesterday for my 13 day ultrasound to check my follies and see if I can trigger and I only had one major follicle that was only 12 mm. I was so. From what I understand, that follicle is rather small. But that does not discount the fact that there could be an egg in there. Doctors like to see the follicle sizes on a medicated cycle at about 19-20+ and follicle sizes at 15-18 in a non-medicated cycle At my scan yesterday, my follicles were 12, 13, and 23mm. They had me take the trigger shot last night. Will only the 23mm follicle be mature, or is it possible for the other two to be mature by the t read mor

Your follicles are too small. Your smallest should be about 18mm before triggering and you shouldn't trigger til around 14, 15, or 16 day of cycle because the follicles grow 2-3mm every 2 days if stimulated right. Read my story... I just had my transfer on Monday, March 21st. It's my fifth cycle Harlo17. 17/04/17. First IVF cycle I had 12 follicles ranging from 16 - 22mm, estrogen 8939 pmol/L 2 days before trigger, resulted in 6 eggs 5 mature. Second IVF cycle I had 10 follicles ranging from 20-26mm, estrogen 10,590 pmol/L 2 days before trigger resulted in 8 eggs 7 mature. Third IVF cycle I had 15 follicles ranging from 16mm - 48mm. Yes, size matters. Especially when it comes to follicle sizes before trigger. But size isn't all and there are other details to be taken into account before putting that trigger shot to use Last month I was trigger on CD 11 with 2 follicles at 15mm and 16mm with a lining of 6.1mm. Does this seem a bit early or am i paranoid? Reply Quote. Topic starter Posted : 06/05/2018 1:10 pm maw123 . Hi happy0, I am 4dpiui. My first iui I triggered on day 13 with one follicle measuring 20mm. IUI took place on day 15 January 2013. I always did better when they waited to trigger me when follicles were in the 18-20mm range. If the follicles are too small, the egg isn't as likely to be mature and capable of fertilization, but wait too long and I think the egg might be too old and not viable either. It's so hard to know

12 mm follicle on cd 13, is there still hope for a trigger

I went in today for a study and my follicles measured 16.5, 15.7, 14.3, 12.4, 10.2 and they want me to trigger tomorrow night and iui Monday am. I was trying to get an idea of how many of these would mature and ovulate to decide if I want to go forward or cancel this cycle. Could you give me an idea on which ones you think woul Eggs from follicles measuring about 20mm at trigger have the highest *chance* of being mature, but that doesn't mean that they will be, or that eggs from other follicles won't. There are so many factors and this is why getting pregnant, whether by IVF or not is such a lottery and such a miracle. IVF looks to set as many of the variables and. I am 43 yrs. old. It it day 10 of my cycle and my dominant follicle is 18mm and I have two more that are 14mm. I am going in for my egg retrieval on day 12. Do you think the two follicles that are 14mm have the potential to reach 18mm before my egg retrieval? If not, is it even worth it to go in for an egg retrieval with only one developed.

Anyone ever have a follicle of only 12mm at ovulation

  1. The goal, or what should be the goal, is to trigger when the majority of follicles are of mature size but not let it go on so long that you begin losing the larger follicles. That balance is the key. In my case, I use 50% maturity as my baseline measure, since follicles tend to grow at different rates. That is to say, that I strive to have at.
  2. I am on my first cycle of Letrozole this month (TTC #1, PCOS), and had an ultrasound yesterday (CD12) to measure follicle size.I have one follicle on each side that each measure 12mm. The doctor said that they were too small for her to give me the trigger shot, but to use an OPK at home, and if I don't get a positive on that by Saturday to come back in for another ultrasound and the trigger.

  5. Hmm. I am no doctor but had almost the same thing happen to me. Mine was later on in the cycle, they found a 12 mm follicle/cyst on day 11. I went back for monitoring again the next day and they found it again and had me do two nights of Ganirelix to prevent ovulation (this was a medicated cycle)

0. With ivf you sometimes get eggs from follicles that are slightly smaller. I had 28 follicles but a lot of them were around 12 like yours, the day before trigger. A nurse that called me with bloodwork on the final appt before trigger told me she only thought 8 would be mature. however they got 22 eggs, 16 were mature This optimal size is influenced by the endometrial thickness. For both drugs, higher pregnancy rates were achieved with the leading follicle being in the range of 23 to 28 mm . Within that range, pregnancy rates were higher when the larger follicles were accompanied by a thicker endometrium and vice versa (see Table 3). These findings can be. However, once hormonal signals trigger the development of follicles and they start to mature and grow, they become known as antral follicles and measure up to 10 mm. These are then visible on an ultrasound and can be counted. This doesn't show the total amount of follicles a woman has on her ovaries, but just noting the amount of visible.

Over 10+ follicles seen, however the 3 largest measured 12mm, 10mm, and 0.9.mm. Took clomid 150 mgs for 5 days starting cd 4. Going back in for another scan tomorrow, which will be cd 12 only.

I have not been given any HCG trigger .I want. We compared female age, BMI, numbers of follicles > 12 mm, on the day of trigger and peak serum E2 levels between the 12 women who had OHSS and the 76 women who did not develop the syndrome. The number of follicles measuring > 12 mm on the day of trigger was significantly different between groups ( Table 5 ) About 14 days into a person's cycle, hormones trigger the release of an egg. During this secretory phase, endometrial thickness is at its greatest and can reach 16 mm. Pregnancy Ovulation trigger is needed in in vitro fertilization (IVF) to get mature eggs. Routinely, human chorionic gonadotropin (hCG) is used for that purpose given its similarity to the natural hormone that does this job in a natural cycle (luteinizing hormone, LH)

Aspirated follicles were grouped, according to follicular volume, into the following arbitrary groups: small follicles with a volume of 0.3-0.9 mL, corresponding to a spherical diameter of 8-12 mm; medium size follicles with a volume of 1-6 mL, corresponding to a spherical diameter of 13-23 mm; and large follicles with a volume of > 6. Usually, your doctor will want to schedule your trigger shot—or hCG/LH injection—when your follicles are just about to reach full mature size. This is around 18 mm. A mature follicle that is about to ovulate will measure anywhere between 18 and 25 mm The timing of the trigger shot to initiate meiosis: This should coincide with the majority of ovarian follicles being >15 mm in mean diameter with several follicles having reached 18-22 mm. Follicles of larger than 22 mm will usually harbor overdeveloped eggs which in turn will usually fail to produce good quality eggs When the leading follicle reached 12 mm, GnRH antagonist was started using Cetrotide 0.25 subcutaneously daily till the day of triggering. Triggering was done when at least 3 follicles larger than 14 mm and at least one of them reached a mean diameter of 17 mm or more. At the day of triggering, women were randomized into 2 groups More than 15 follicles (≥12 mm in diameter) on ultrasound, and/or estradiol level of > 3500 pg/ml on the day of trigger. Exclusion Criteria: History of three or more miscarriages. History of three or more previous IVF failures. Abnormal uterine cavity (Hysteroscopy or HSG)

  4. ) found that a 1 mm difference in follicle size at the time of human chorionic gonadotropin (hCG) trigger raises the odds of clinical pregnancy significantly, with an observed clinical pregnancy rate ranging from approximately 8% for mean follicle diameter of 19 to 20 mm, to 11% for 20 to 21 mm follicles, and 16% for follicles 21 to 22 mm (see Figure 1 in Reference 1)

Trigger shot was 1ml of suprecur. They collected 10 follicles with 8 mature eggs out 28 follicles. 2nd cycle: I've stimmed for 8 days. Menopur dosage was more of a roller-coaster at 225,300,75.

In HMG and clomiphene + HMG cycles for patients less than 35 years of age, the incidence of three or more implantations per cycle (but not of twin implantations) was tripled, while pregnancy rates were not significantly increased, when E2 was over 1000 pg/mL, when six or more follicles were > or = 12mm, and when four or more follicles were > or = 15mm However, the 25 mm follicle is large and the egg within it might be over-mature. So the net might be 3 eggs. If you wait 2 days to trigger, you will lose the 25 mm, which you've probably already lost anyway, but will gain the 12 mm follicle and the 17's won't be over-mature so the net would be 4 eggs

Size of follicles at trigger? - Fertility Issues

Once a dominant follicle measures greater than 12 mm, follicular growth of 2 mm (1-3 mm) per day is expected [].Growth continues until follicular maturation at 18-21 mm, and at that point the oocyte inside is ready to ovulate, that is, complete meiosis, and be released in preparation for fertilization Small: The follicle usually reaches 18 to 20 mm when it is ready to ovulate. In the days preceding ovulation, follicles usually grow approximately 1 mm per day. Based on your number, i would guess you will be ovulating in 5 to 6 days, but this is just a guess, and it may be that you won't ovulate at all this cycle Many patients ask what is the ideal follicle size to be able to trigger ovulation. Dr. Timmreck offers, The maturity of an egg in the follicle is in part reflected by the follicular size; on average, the ideal follicular size is 18 to 20 millimeters or larger, depending on the type of medications used

Severe early ovarian hyperstimulation syndrome following GnRH agonist trigger with the addition of 1500 IU hCG There were 23 women with a mean estradiol level of 4891 ± 2214 pg/ml and a mean number of >12 mm follicles of 20 ± 6 on the day of ovulation triggering. OHSS was categorized according to the Golan criteria. The number of. On the first scan, my biggest follicle was 14mm, and on the second scan, I had two big ones of 17mm and 18mm. For the final scan, even more follicles had developed/grown, and I had four measuring 18,19, 15 and 14. It was deemed that all four follicles could potentially release eggs, so the cycle was cancelled. Cycle tw The ovary is made up of follicles, which are very tiny fluid-filled sacs, each containing an immature egg (or oocyte). During the first two weeks of the menstrual cycle, hormones   regulated by the hypothalamus and released by the pituitary gland trigger a few of these follicles to grow and the egg inside the follicles to mature On the day of trigger, estradiol was 1472 pg/mL, and the lead follicle was 21.5 mm with a total of 25 follicles measured > 12 mm. She was triggered with 5000 U hCG. She had a total 23 oocytes retrieved, 17 of which were metaphase II and vitrified (three metaphase I, one germinal vesicle, and two atretic oocytes were discarded) Ovulation induced with hCG or GnRH agonist when the dominant follicle reached 18 mm in diameter and ovarian stimulation was started 2-3 days after trigger Luteal phase Start ovarian stimulation without antagonist and initiate it when 12mm Outcomes comparable excepted slightly longer stimulation, more gonadotropin

The mean number of follicles >12mm on the trigger day and the number of oocytes retrieved at OPU were significantly higher in SPL of 10-12 days (P = 0.002 and 0.011 respectively). But there were no significant differences in the mean number of grade A/B OCC or M2 oocytes among all three groups of SPL ( P = 0.056 and 0.100) Had 12 mm and 10mm follicle on day 13. 16.7 mm and 12.8 mm on day 15.

With free fluid ++ If the follicles fail to mature, the cycle may be cancelled before the egg retrieval process. Ideally, fertility clinics would like to see 4 mature follicles before the trigger shot. Once again, though, there is no magic number, and this is a very individual situation.

The last injection of GnRH antagonist was administered on the day preceding the ovulation trigger. When at least 3 follicles had reached 18 mm in diameter, ovulation was triggered either with a single dose of 0.2 mg triptorelin (Decapeptyl, Ipsen) or of 250 mg.

I have a 4 part question: 1

leading follicle that maximizes the probability of pregnancy, with lower rates for both smaller and larger sized leading follicles. The optimal size of the leading follicle in ovulation induction with CC and Letrozole is similar for both drugs, 24mm for CC and 24.8mm for Letrozole, and is closely related to the endometrial thickness The small follicles (10-12) may or not be mature. But if the lead follicle is 14 mm, none of the eggs have yet reached maturity. Giving hCG would not be enough to achieve maturity. I personally have gotten mature eggs from smaller follicles. Also, (HCG) trigger does not slow follicle growth, they should continue to grow until ER. Thinking of.

Egg Maturity and HCG Trigger: Why Do I Have Immature Eggs

On day 8, a pelvic ultrasound showed that there was only one follicle > 17 mm in each ovary so stimulation continued and a pelvic ultrasound was repeated on day 10 showing an excessive follicular response (27 follicles >12 mm). The pre-trigger peak E2 was 18,959 pg/ml; 32 oocytes were collected and 24 embryos were cultured So the dots on the right are where my follicles were at today, the group in the middle is from Friday, and the group on the left from last Monday so they've been continuing to grow at a good rate. Anything over 12mm on the day of trigger (today) is likely to produce a mature egg with the hope of getting as many over 18mm as possible

This includes monitoring the number and size of the follicles on each ovary. When your follicles have reached around 18-20mm in diameter they are deemed ready for egg collection.

dominant follicle reaches 12 mm. In order to delay breakthrough bleeding during OR, Medroxyprogesterone (10 mg/day) is added in those cases where the leading follicle is <14 mm on day 12. Whenever there are 3 follicles with an 18 mm diameter or one dominant follicle exceeding 20 mm, maturation trigger i So, the proper way to do this is daily ultrasound, if necessary, as your follicles reach closer to the 18 mm point. Once the follicle is 18 mm (my personal preference is 20mms), then the HCG shot is given and the IUI is done at 36 hours if only one IUI is done or at 24 and 48 hrs if two are done (My preference is the two IUI protocol)
