What is a good antral follicle count for IUI?

Various methods of measuring ovarian reserve exist, including antral follicle count (AFC). Ovarian reserve tests, as they relate to pregnancy rates, have mostly been studied in IVF populations (1-3). In the few articles available, an AFC minimum of 5 to 7.5 are cited to improve pregnancy outcomes in IUI cycles (4, 5).

Can you have too many follicles for IUI?

Caution should be used in proceeding with IUI following ovarian stimulation when there are > 2 mature follicles in women under the age of 40 due to the substantially increased risk of multiple gestation without an improved chance of singleton clinical pregnancy.

How many follicles are normal in each ovary for IUI?

Follicles Needed for an IUI or Gonadotropins Cycle As with Clomid, ideally, you only want one or two follicles to grow to maturity. Injectable fertility drugs (gonadotropins) come with a higher risk of a multiple pregnancy. It’s possible to develop three, four, or even more mature follicles.

Can antral follicle count be too high?

A count around 20 indicates high ovarian reserve and strong chances of success, and counts higher than 30 could indicate PCOS, which won’t necessarily interfere with a healthy and successful pregnancy.

What size follicles trigger IUI?

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

What size follicle is too big for IUI?

The present study examined almost 1000 IUI cycles receiving either clomiphene citrate (CC) or letrozole for ovulation induction and suggests that the clinical pregnancy rate is higher when the lead follicle is 2.3 or 2.4cm in diameter and endometrial thickness is 9mm or greater.

How many eggs are ideal for IUI?

Most doctors aim for just one or two eggs for an IUI cycle. If you’re having an IUI cycle with superovulation, having no more than four follicles is best. Remember that if you ovulate four eggs, there is a possibility you could conceive quadruplets.

What causes high antral follicle count?

A high or very high number of antral follicles indicates that the ovaries will likely respond well to ovarian stimulation, increasing your chances of pregnancy. An antral follicle count in the low-to-median range may indicate declining ovarian reserve.

Does High AFC mean PCOS?

What do these findings mean for women with PCOS? We already know that women with PCOS tend to have higher antral follicle count (AFC) and anti-Müllerian hormone (AMH) levels than those who do not. We also know that markers of ovarian reserve such as AFC, AMH and ovarian volume decrease with increasing age.

What size egg is best for IUI?

Mature follicle of 18-20 mm in size and endometrial thickness equal to or more than 7mm with good endometrial and perifollicular blood flow give result.

Can first IUI be successful?

Statistics show that the majority of IUI pregnancies occur in the first three to four cycles of IUI. One study concluded that 88% of all successful IUIs happen within three cycles and 95% within four. Another study found that 90% of IUI pregnancies occur in the first three cycles of IUI.

Is a 32 mm follicle too big?

Usually once the follicle is greater than 24 mms, the egg within is overmature and therefore no longer viable.

How successful is IUI on first try?

On average, a woman under 35 will have a 10 to 20 percent chance of pregnancy with each IUI, while a woman over 40 will have a two to five percent chance.

What does high antral follicle count mean?

What is a good AFC number?

16-30 Good – regular number. An excellent response to stimulation is expected, even with the use of lower doses of the hormone based drugs. A great chance for pregnancy. > 30 Very high number, characteristic for polycystic ovary syndrome.

What is a good AFC count?

Analysis. What is considered a normal AFC varies between institutions. It is roughly considered to be about 3-8 per ovary. The AFC count is a major predictor of the ovarian reserve and could reflect the size of the remaining primordial follicle pool.

How big should follicles be for trigger shot IUI?

20mm
Using A Trigger Shot: When the follicle is at least 20mm and the uterine lining is at least 7mm, a medication (known as a “trigger shot”) can be given to trigger ovulation.

How many antral follicles are normal in each ovary?

The number of antral follicles varies every month. 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.

What is the ideal antral follicle count for IVF?

Counting antral follicles using an ultrasound can be a subjective process, but most fertility specialists will agree that a count of four or fewer will likely lead to poor IVF results. An ideal antral follicle count depends on the age of the woman, as 40 year old women are not expected to have the same antral follicle count as women who are 30.

What does a high or low number of antral follicles mean?

A higher number of antral follicles indicates likely success with the IVF process. But a low number usually indicates a poor prognosis of success, and IVF plans may need to be redirected when very low ovarian reserves are detected.

What do antral follicle counts tell us about ovarian reserve?

I am going to talk about antral follicle counts and ovarian reserve. Antral follicles are small cystic structures within the ovaries that can be visualized with ultrasound. By counting the number of antral follicles we can learn about the quality of eggs remaining.

What are antral follicle counts by ultrasound?

Antral follicle counts by ultrasound are one of the best ovarian reserve tests that we currently have available. What are Antral Follicles? Antral follicles are small follicles (about 2-9 mm in diameter) that we can see – and measure and count – with ultrasound. Antral follicles are also referred to as resting follicles.
