What is a good egg size for IVF?
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.
How many eggs are average for IVF?
Ovarian stimulation is used to mature multiple eggs for egg retrieval. Even if ovulation is normal, fertility drugs are used to produce more than a single egg because pregnancy rates are higher with more eggs. An average of 10 – 20 eggs are usually retrieved for IVF.
Does egg size determine quality?
The good news is that egg size can be tailored to meet consumer expectations to some extent. For example, the heavier a hen is at the onset of lay, the bigger the egg size will be (Kay). By managing the body weight of hens, producers can also manage egg size.
Is 19 mm follicle size good?

The start of an IVF cycle begins by using synthetic hormones to stimulate the ovaries to produce multiple eggs — rather than the single egg that typically develops each month. Multiple eggs are needed because some eggs won’t fertilize or develop normally after fertilization.
What is a good follicle size for IVF retrieval?
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).
What causes poor egg quality IVF?
Poor egg quality is caused by diminished ovarian reserve and is one of the most common causes of infertility, especially in women over 35. Egg quality is important because it determines embryo quality. Poor egg quality is closely associated with chromosomal abnormalities in embryos, also known as aneuploidy.
