Fertility Techniques and Tests

At WeFIV, in addition to the Assisted Reproduction treatments we perform, we offer a range of supplementary techniques and tests designed to enhance the success rates of each procedure.

Techniques and Tests

In order to select the embryo with the highest probability of implantation, various tests and techniques can be performed. These techniques complement assisted reproduction treatments, especially when detecting hereditary diseases.

Oocyte Vitrification

This technique's main advantage is that it allows women to preserve their fertility in cases where they choose to delay motherhood. Thanks to this technique, a woman can preserve eggs during her youth and use them later in life, increasing the success rate of assisted reproduction treatment.

Sperm Bank

The sperm bank is essential for assisted reproduction treatments. It is a necessary resource for couples in which the male partner has fertility problems. At WeFIV, we work with sperm banks that meet all the requirements for sample acquisition and quality.


Intracytoplasmic Sperm Injection (ICSI) is used in In Vitro Fertilization (IVF) treatments, introducing the sperm into the egg with the help of a specialized pipette to facilitate fertilization.


This technique allows professionals to select healthy sperm to be used in assisted reproduction treatments. This technique significantly increases the chances of achieving pregnancy.

ROPA Method

This method is used for female couples who wish to have a child and both participate in motherhood. In these cases, both participate in the In Vitro Fertilization process, one as the gestational mother and the other as the biological mother through egg donation.

Time-Lapse Incubator

At WeFIV, we have the latest technology to analyze the development of embryos fertilized in our laboratory. The Time-Lapse Incubator optimizes embryo culture conditions and allows for better embryo selection for implantation, increasing the chances of pregnancy.


Preimplantation Genetic Diagnosis (PGT) aims to transfer a healthy embryo in high-complexity treatments. In other words, it involves biopsying pre-embryos to distinguish those that are healthy from those affected by certain genetic-hereditary diseases.


The Genetic Compatibility Test (CGT) is performed to prevent the future baby from being born with a genetic disease. The objective of this test is to identify the disease and understand if the maternal gene is compatible with the paternal gene, thus we can avoid transmitting the disease to the baby.
