It depends on how many eggs can be frozen in one cycle. It depends upon a woman’s egg reserve. And if she has a very good egg reserve, she’s going to be more responsive to the fertility drugs that we use to stimulate the eggs to grow. And with one cycle she may make about anywhere between 10 to 15 eggs. We don’t want to want to make too many eggs. But there’s a range so even young healthy women who want to go to fertility stimulation, on average, they’re going to take about 12 to 15, as you had older, become less responsive to the fertility drugs and make less number of eggs. So if I have a woman who is say 38, and she’s had five eggs retrieved, those may be very good, healthy five eggs. However, the number that she needs to get to they give herself a 50% chance of having one baby in the future should be closer to that 15 number. So she may have to undergo two or three cycles to get to that number that’s going to be beneficial for her in the future.

There is no general rule as to how many eggs should be frozen per patient. Generally speaking it’s a numbers game – the more eggs you have in storage, the more likely one of those would be. However as a rule or recommendation I make for my patients is that having 15 in storage usually gives you at least the highest percentage of success. It’s not to say that having less than 15 eggs doesn’t give you success, in fact I’ve seen so many patients with very few eggs frozen lead to babies or have babies eventually but it’s also important to know that every patient reacts differently to stimulation so sometimes you can just need one cycle to get a sufficient number of eggs but sometimes you may need more cycles to get a good number of eggs.

This relates to the previous question and yes it depends on the ovarian reserve and the age. These are the two main predictors of success. Depending on the age of the woman, we would recommend to have just one cycle of egg freezing because we would store a good number of eggs or we may need to do more than one cycle, especially in patients that have a lower reserve or that are older because in that case we just need to compensate a bit to some extent the effect of age on the quality with a higher number. Yes, sometimes you may need to do more than one cycle but if you have a normal ovarian reserve or a good ovarian reserve and you are young probably just one cycle will be sufficient.

We recommend at list freeze 15 eggs, but it depends on the ovarian reserve, sometimes the patient will need to have more procedures to reach a good number of frozen eggs.

How many cycles do I need to freeze my eggs?

What is the ideal number of oocytes to be frozen? Can this number be achieved during one stimulation cycle or will I need more than one?
