How Many Eggs and IVF Rounds Do You Need? Realistic Numbers

The first question after an egg retrieval is usually how many eggs were collected. The more useful question is how many of them become embryos. One patient shared her numbers to show what that looks like:

This guide explains what egg numbers mean, how age and AMH change the picture, how many rounds people tend to need, and what a round costs at home and in China. It is general information, and your fertility doctor can tell you what to expect for your own case.

How many eggs are usually retrieved in an IVF cycle, and how many are mature?

There is no single normal number. Egg counts vary widely with age, ovarian reserve and the stimulation plan, and what matters more is how many eggs go on to become embryos. Stimulation usually lasts about 8 to 10 days, sometimes up to around 14, and eggs are collected about 34 to 36 hours after the trigger injection.

Numbers fall at every step. Not every follicle gives an egg, not every egg is mature, not every mature egg fertilises, and not every embryo grows to the blastocyst stage at day 5 or 6. Patients often call this attrition. A patient in China described a result her doctor was pleased with:

A good question for your doctor before you start is not only how many eggs they expect, but how many blastocysts that usually leads to for someone like you.

How does age change egg numbers and IVF success?

Age is the biggest single factor. Younger women tend to produce more eggs, and a higher share of their eggs have normal chromosomes, so each egg is more likely to lead to a baby. The UK fertility regulator reports that in 2023 the birth rate per embryo transferred was 35% for patients aged 18 to 34 using their own eggs, and 5% for those aged 43 to 44.

In practice, people in their 40s often need many more eggs to reach one healthy embryo. A patient who did two retrievals at 43 described it this way:

None of this means IVF cannot work later in life, but it is why doctors often talk about the number of retrievals rather than one cycle.

How many IVF cycles are usually needed?

Many people need more than one cycle, so it is sensible to plan and budget for the possibility of a second round rather than assume the first will work. How many you need depends on age, egg numbers, embryo quality and the cause of infertility.

Some couples who come to China have already had several attempts at home. In two cases reported by Chinese media, one couple had two failed IVF attempts in France and then two egg retrievals in China, in July and October, before their transfer; another had four failed cycles in Europe before treatment in Guangzhou. Their outcomes were their own and say nothing about anyone else's chances, but they show that planning for more than one retrieval is normal.

Public funding at home usually covers only a limited number of cycles. Ontario funds 1 IVF cycle per lifetime and does not cover fertility drugs, which it puts at about CAD 5,000 per cycle. Victoria's public fertility care allows up to 2 cycles per lifetime. In the UK, the regulator notes that some areas fund three attempts and others one or none.

Paying privately, the cost of each round adds up quickly. In China, People's Daily reported in 2024 that one treatment cycle typically costs CNY 30,000–40,000 (≈ USD 4,500–5,950), with medicines often a large part of it. Chinese insurance covers IVF only for insured residents, so foreign patients pay the full price, and international departments may charge more. A cross-border couple treated in Guangzhou, reported in 2026, paid about CNY 30,000 (≈ USD 4,500) for one complete cycle.

A round in China is also a trip. The UK regulator says one cycle takes 3 to 6 weeks, and the Guangzhou couple stayed about 3 months, with 7 to 8 hospital visits. A second round usually means another trip, so ask the hospital early whether it expects one retrieval to be enough.

What are the chances of IVF with low AMH?

Low AMH usually means fewer eggs per cycle, while age remains the main guide to egg quality. Many people with low AMH do conceive with IVF, but they may get fewer embryos per round and need more rounds. Your doctor will use AMH together with your age and an ultrasound count of follicles to suggest a stimulation plan and a realistic number of eggs, so ask them to explain what your result means for you.

What are realistic IVF success rates, including in China?

Success rates are averages that depend heavily on age and on how they are counted, so treat any single figure with care. A clinical pregnancy, confirmed by scan, is not the same as a live birth, and rates per transfer differ from rates per started cycle.

China's most recent peer-reviewed national data are from 2016, from 133 reporting centres: the delivery rate was 42.9% per fresh IVF transfer and 39.8% per frozen transfer. Chinese media reported a national average clinical pregnancy rate of about 50% in 2021. These figures show that IVF in China is an established, large-scale treatment, with 645 licensed centres in 2026, but they are not a promise for any patient, and we do not claim that rates in China are higher than elsewhere.
