Fertility preservation is one of the greatest medical advances in assisted reproduction treatments, because it gives women more freedom to choose the best time for them to start a family.
There are numerous factors that force women to put off having children. Lack of a partner, career considerations and economic matters are common issues that can mean that the best reproductive age may not mean that the right time to start a family.
Reproductive medicine allows today's women to preserve their fertility by vitrifying (freezing) their eggs when they are young, guaranteeing a supply of good quality eggs to use when their time is right to have a baby.
The success of this fertility treatment depends on harvesting eggs before the woman is 35, when good quality eggs are still available. This means that the woman is more likely to succeed in getting pregnant from implantation. Fertility specialists also recommend regular check-ups to ensure that the reproductive system is functioning normally.
Fertility preservation treatment is a potential reproduction solution for patients who have to undergo localised chemotherapy or radiotherapy or who must take medication with a significant impact on fertility or ovarian reserve. Fertility preservation freezes the best eggs so that when the patient recovers from the illness, she can conceive a baby with her own eggs.
As an assisted reproduction centre, our goal is to provide successful fertility preservation treatments. That’s why our patients undergo a detailed medical examination to determine the most suitable treatment in each case, selecting the one that best suits the patient’s personal circumstances.
Step 1: Ovarian stimulation
Fertility preservation process starts with ovarian stimulation, which is carried out according to personalised protocols. The purpose is to obtain a sufficient number of eggs, which increases the possibilities of becoming pregnant.
Ultrasound examinations are performed during this 10 to 20 day period to check that the patient is responding to the drugs prescribed and that the follicles are growing steadily and will reach the optimal size to guarantee puncture and, therefore, reproductive success.
Step 2: Follicular puncture and aspiration
A large number of eggs suitable for maturing have been produced in Step 1. Step 2 is when ovulation is stimulated and the transvaginal ultrasound-guided follicular aspiration is programmed. It is not an invasive procedure, but it is performed in the operating theatre under mild sedation to avoid any discomfort and patients can go back to normal life after the operation.
Step 3: Egg vitrification
Lastly, the optimal eggs obtained frozen in liquid nitrogen to a temperature of -196C. This procedure stops the eggs from ageing until the time comes for fertilisation and transfer to the patient. Cryopreservation preserves eggs in the same condition as when they were frozen.
