Question about how many eggs to expect

While there's no way to know for certain, an antral follicle count may be a good place to start... it's done via vaginal ultrasound and it's usually done at the beginning of each IVF cycle along w/routine blood work.... FSH, E2, P4. AMH ( Anti-Mullerian Hormone) levels can also be tested - another predictor of ovarian reserve - though the results can be misleading. Antral follicle count seems to be the way to go. Just keep in mind, that the number of antral follicles at the beginning of a cycle does not always correlate w/the number of eggs retrieved - sometimes more, but often less. I speak from experience. But, it is a good initial predictor of ovarian reserve. I've pasted info on antral follicles below. HTH. Good luck!
Antral follicles are small follicles (about 2-8 mm in diameter) that we can see - and measure and count - with ultrasound. Antral follicles are also referred to as resting follicles.
Vaginal ultrasound is the best way to accurately assess and count these small structures. In my opinion, the antral follicle counts (in conjunction with female age) are by far the best tool that we currently have for estimating ovarian reserve and/or chances for pregnancy with in vitro fertilization.
Presumably, the number of antral follicles visible on ultrasound is indicative of the relative number of microscopic (and sound asleep) primordial follicles remaining in the ovary. Each primordial follicle contains an immature egg that can potentially develop in the future. So when there are only a few antral follicles visible, there are much less eggs remaining as compared to when there are more antral follicles. As women age, they have less eggs (primordial follicles) remaining, therefore they have fewer antral follicles on ultrasound.
Antral follicle counts are a good predictor of the number of mature follicles that we will be able to stimulate in the woman's ovaries when we give injectable FSH medications that are used for in vitro fertilization. The number of eggs retrieved correlates with IVF success rates.
