Is 15 eggs good for egg retrieval? ›

A study of more than 400,000 IVF cycles has found that doctors should aim to retrieve around 15 eggs from a woman's ovaries in a single cycle for the best chance of achieving a live birth.

As a rule of thumb, however, having about ten to 12 mature eggs after egg retrieval (not all eggs retrieved will be developed or mature enough to fertilize) is a good number of eggs and will give a woman a good chance of having at least one normal embryo, which gives a woman a 65 percent chance of pregnancy.

As a general guideline, however, antral follicle counts can be used to help determine the likelihood of success for ovarian stimulation and IVF, and may also be used to guide dosing for fertility medications. 15 to 30 is considered a good number.

In general, an average of 8 to 14 eggs are typically retrieved from a woman's ovaries with IVF; however, its ultimately not the number of eggs that matter but the quality. 1 high quality egg is better than 20 poor quality eggs when it comes to success rates.

For women less than 35, it is ideal to freeze at least 12-15 eggs for a high chance of one child; this number increases as women get older. Of the hundreds of thousands of egg retrievals we have done, we see an average of 9-10 eggs retrieved per patient in one cycle; the average patient age is 35.9.

An average of ten to 20 eggs are usually retrieved for IVF, but the number can be higher or lower. You would think more eggs is always better, but that's not the case. Researchers who analyzed thousands of IVF cycles found that the magic number of eggs retrieved from IVF treatment that lead to a live birth is 15.

What is the average number of follicles during in vitro fertilization (IVF) treatment? Ideally patients will want to have around 10 follicles before ovulation is triggered with fertility drugs. It's possible for the process to be performed with fewer than 10 follicles, and success can still be achieved.

As a general rule of thumb, at RMA New Jersey, which has one of the best embryology labs in the country (as evidenced by the clinic's high success rates), about 80 percent of eggs will fertilize (day 1 success), and of those, about 30-50 percent will make it to the blastocyst stage (day 5 or 6).

An ideal IVF follicle size for egg retrieval is typically around 15 to 22 millimeters in size, which falls right in line with the ideal size for an IVF trigger shot.

Anywhere between 8 and 15 follicles is considered an acceptable amount. During an egg retrieval, your doctor will aspirate the follicles with an ultrasound-guided needle. Every follicle will not necessarily contain a quality egg.

Is 15mm follicle mature for IVF? ›

The stimulation must result in a minimum of 3 mature (or close to mature) follicles (follicles are mature if they are 16-20mm in average diameter on the day of human chorionic gonadotropin (hCG), where a shot is administered to stimulate ovulation).

If you have lots of follicles, then you have the potential to release more eggs increasing the chance that one of those eggs will be healthy enough to result in a successful pregnancy.

The more eggs produced from each IVF cycle, the better the chances of a live birth, but only up to about 13 eggs; after that, over stimulation may result in lower-quality eggs that are less likely to become fertilized and result in healthy embryos.

While all the growing follicles may release an egg, the egg needs to be mature to be able to fertilise. Generally, doctors want the follicles to be around 18mm or more to be considered mature, but I found this varied depending on the doctor.

Grade 1 through 2.5 embryos seem to have the greatest potential for developing to the blastocyst stage. However, a grade 3 embryo may also be of good quality if its appearance can be explained by asynchronous cell division rather than by poor development.

The number of eggs to freeze also depends on the woman's age and how many children she wishes to have in the future. Women under age 35 should freeze 20 eggs for an 85% chance of having one child; women 38-40 should freeze 30 eggs for a 75% chance of having one child.

If she'd always dreamt of a big family, she should consider freezing 25 eggs, for over a 1 in 2 chance of having three children.

It found that the best chance of live birth was seen when around 15 eggs were collected. However, as many other studies have shown, the chance of success began to decline after 20 eggs were retrieved.

Roughly about 50 % of eggs will develop into day 3 embryos and at around 20-25% of eggs will reach the blastocyst stage at day 5.

How do you maximize an egg retrieval? ›

On average, women in their mid 20s to early 30s have around 12 to 30 antral follicles, while women aged 35 to 40 may have between 8 and 15 and women aged 41 to 46 may have somewhere between four and 10.

Here is the range of what you could expect by age of a normal antral follicle count (AFC): Age 25 to 34, AFC from 10 to 13. Age 35 to 40, AFC from 10 to 8. Age 41 to 46, AFC from 7 to 5.

On average ten to twelve follicles are produced per cycle, but this can vary from person to person and is affected by multiple factors such as age, medical history and your individual response to ovarian stimulation.

Most healthy people can eat up to seven eggs a week without affecting their heart health. Some choose to eat only the egg white and not the yolk, which provides some protein without the cholesterol.

Ultimately, the chances that one egg retrieval cycle will eventually result in a live birth (based on data from the Society of Assisted Reproductive Technology, or SART) are 55.6% for people under 35; 40.8% for people 35-37; 26.8% for people 38-40; 12.6% for people 41-42; and 3.9% for people 43 and over.

Six eggs is definitely enough for IVF if that's what you've managed to produce. Quality over quantity – you're much better off having six eggs than 60 eggs and quality over quantity for sure. So six eggs is definitely enough for IVF.

In a fertility cycle, the ideal size is between 18 and 22 millimeters in diameter. Once a follicle reaches this size, it means estrogen levels are rising and the uterine lining has thickened.

Follicle Size - 16X17 Mm Follicle On 15Th Day Of Cycle.

In most centers, triggering is administered once two to three ovarian follicles are at least 17–18 mm in diameter.

Is 12 a good number of follicles? ›

A woman is considered to have adequate or normal ovarian reserve if the antral follicle count is 6-10. If the count is less than 6 the ovarian reserve could be considered to be low, whereas a high reserve is greater than 12.

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).

The stimulation must result in a minimum of 3 mature (or close to mature) follicles (we consider follicles to be mature if they are 16-20mm in average diameter on the day of HCG). Alternatively, if there are 2 follicles 16-20mm and at least 2 more that are 13-15mm, we can proceed to the egg retrieval.

As the follicles grow, the eggs inside them are developing too. When a follicle gets larger than about 13 mm, its egg is more likely to be mature and therefore capable of being fertilized. Once the largest follicles reach about 17 to 18 mm, they (and you) are ready for egg retrieval.

The existence of follicles with a trigger day diameter greater than 25 mm may alter the result of IVF-ET, lowering the clinical pregnancy rate (40.92 percent vs 30.2 percent, P = 0.008) and the live birth rate (37.24 percent vs 27.43 percent, P = 0.017).

Follicle size for Pregnancy

Follicles play an important role in determining your chances of getting pregnant as they ensure the ovulation process (the release of an egg from the ovaries).

The size of a follicle tells the fertility specialist how much an egg has developed during a woman's cycle. The bigger the follicle, the better it is for the IVF process. For most IVF treatments, a follicle that is around 15mm-22mm (micrometers) large is most likely to produce a viable egg.

The Timing of The Trigger Shot During IVF

This must coincide with most of the ovarian follicles being greater than 15 mm in diameter and with several follicles having reached 18 to 22 mm. The follicles grow an average of 2 mm per day during the later stages of stimulation.

We test it by performing a baseline pelvic sonogram during the first three days of your menstrual cycle. This shows us how many follicles are in your ovaries. A normal amount is 12 per ovary; 1-10 is considered low.

It's widely known that a woman is most fertile in her 20's. Studies show that women in their 20s and 30s have the most success when getting pregnant through IVF and other reproductive technologies.

How many embryos is a good number? ›

Research shows that 8 is best. (Day 3 embryos that had 8 or more cells showed a significantly higher live birth rate). However, not all good quality embryos follow the rules.

It is clear from the secondary follicles in the multiple pregnancies that follicles of diameter 16 mm and 15 mm are capable of contributing to the implantation. Follicles with FD=14 mm also appear capable of yielding an implantation.

USDA Grade AA – The freshest and highest quality eggs will receive a Grade AA. USDA Grade A – Very high quality eggs will receive a Grade A. USDA Grade B – Grade B eggs are usually used for breaking stock (liquid eggs) and baking, dependingon the number of defects.

The highest egg grade is AA, followed by A, then B, and the letter takes appearance and both exterior and interior quality into account.

Always purchase eggs from a refrigerated case. Choose eggs with clean, uncracked shells. Don't buy out-of-date eggs. Look for the USDA grade shield or mark.

For women with 1–4 eggs at retrieval it was 30.8% and for 5–9 eggs it was 36.2%. In women age 35–39 (n=543), optimal pregnancy rates (34.8%) were achieved with 5–9 eggs at retrieval. Less than 5 eggs significantly reduced the pregnancy rate (15.6%) whereas more than 10 eggs yielded pregnancy rates between 28 and 29%.

The required number of follicles for IVF is usually between eight and 15 mature follicles, depending on your doctor's recommendations for your specific situation. Three follicles are usually the minimum amount for the trigger shot and egg retrieval process to take place.

Women under 38 in our IVF program have acceptable live birth rates even with only 3 – 6 eggs, do better with more than 6 eggs, and do best with more than 10 eggs. Women 38-40 and 41-42 years old have low live birth rates with low egg numbers. Success rates are much better when relatively high egg numbers are obtained.

The number of eggs to freeze also depends on the woman's age and how many children she wishes to have in the future. Women under age 35 should freeze 20 eggs for an 85% chance of having one child; women 38-40 should freeze 30 eggs for a 75% chance of having one child.

Fascinating research examining the link between live birth rates and the number of eggs retrieved in one in vitro fertilization (IVF) cycle indicate that 15 may be the “magic number” to collect for the most successful outcomes.

What size follicles are good for retrieval? ›

It's possible for the process to be performed with fewer than 10 follicles, and success can still be achieved.

Remember, even if all of your embryos are perfect on day 3, on average only 40-50% of them will become blastocyst on day 5.

Roughly about 50 % of eggs will develop into day 3 embryos and at around 20-25% of eggs will reach the blastocyst stage at day 5.

women under 35 years old need nine oocytes to get one embryo; 35–37 years old – about 12 oocytes; under 42 years old – 16; over 42 years old – an average of 100 oocytes.

A single cycle of egg freezing can cost anywhere from $8,000 to $20,000. Costs may go up depending on the number of cycles needed and, later, embryo creation and implantation fees.
