Egg accumulation

The ideal technique for patients with low ovarian response

What is it?

It consists of carrying out ovarian stimulations over several cycles to accumulate a greater number of eggs for IVF-ICSI. Like this, the eggs are frozen until an optimum number have been collected, increasing the number of embryos created and therefore, the chances of success, by having a greater number of attempts.

When is it used?

Patients with low response to stimulation

When an adequate number of eggs are not obtained in a single cycle.

Women with low ovarian reserve

When there is a limited amount of eggs available.

Patients with altered karyotypes

To have a higher probability of achieving viable embryos after Preimplantation Genetic Diagnosis.

Women over 40

Because it is often difficult to obtain the desired number of mature eggs in a single cycle.

Benefits of egg accumulation

It improves the efficiency of the treatment by making a greater number of eggs available for fertilisation.

It allows treatment to be tailored to the specific needs of the patient, offering better opportunities in complex cases.

It reduces stress and costs by avoiding the need to repeat the entire process if a first cycle is unsuccessful.

In which treatments can it be applied?

IVF- ICSI PGD ROPA method Egg freezing

How is it done?

Ovarian stimulation Cycle monitoring Egg retrieval Vitrification and accumulation

We plan a course of hormone therapy to stimulate the ovaries to produce as many mature oocytes as possible.

We monitor follicular development by means of vaginal ultrasound scans and hormone analysis and, when we obtain a good number of dominant follicles, we induce ovulation and schedule egg retrieval.

We retrieve the eggs in the operating room in a short procedure, with sedation and painkillers. Each follicle is punctured to extract the follicular fluid so that biologists can examine the presence of oocytes and their maturity.

The mature eggs are vitrified and stored. Subsequently, the doctor plans a new cycle of stimulation to obtain more eggs that will be added to those already obtained in order to carry out an ICSI fertilisation.

FAQs about egg accumulation

In which situations is egg accumulation recommended?

In cases where the patient has a low ovarian response to stimulation and we do not achieve a good number of mature eggs. Also with altered karyotype and women over 40 years of age.

What is the ideal number of eggs to continue treatment?

At IGIN we consider that eight oocytes is the minimum number of eggs recommended to move on to the fertilisation phase of the treatment. If in a single cycle the patient does not obtain this minimum number of oocytes, the doctor will probably advise her to carry out an egg accumulation.

How much does egg accumulation cost?

Each additional stimulation cycle at IGIN costs €2,485.

Do eggs that are vitrified for storage lose quality?

Vitrified eggs are subjected to a rapid freezing process that minimises damage and preserves their quality. Despite the high survival rate, it is possible that some eggs may not survive the process, although this is rare.
