Assisted Reproductive Treatments

At WeFIV, we’re leaders in Assisted Reproductive Treatments, and we’re backed by a team of specialists with expertise in the latest techniques and procedures.


State-of-the-art technology is present in every area of our center, from our lab and operating rooms to consultation rooms. Every aspect is focused on helping those struggling with fertility issues.

Intrauterine Insemination

A low-complexity treatment where previously selected sperm are introduced into the woman's uterus in the lab.

In Vitro Fertilization

A high-complexity treatment where fertilization occurs in the lab, outside the woman's body, and the embryo is then transferred to her uterus.


Egg Donation

A treatment where a woman receives eggs from a donor to become a mother.


Fertility Preservation

We offer fertility preservation treatments for women who want to delay motherhood without compromising their fertility.

Fertility Tests and Techniques

We provide a range of techniques that complement Assisted Reproductive Treatments and increase the chances of achieving a healthy pregnancy.


Aims to freeze the embryo for future use, either because the patient wants to preserve her fertility or because multiple embryos were obtained during IVF and not all are transferred at once.

Sperm Bank

Having a sperm bank is crucial for Assisted Reproductive Treatments, as 30% of fertility issues in couples are related to male issues.


Intracytoplasmic Sperm Injection (ICSI) is a technique that involves injecting the sperm into the egg through a puncture.


MACS is a technique used in IVF to distinguish the healthiest sperm from those with issues.

ROPA Method

Reception of Oocytes from the Partner is a technique we offer to female same-sex couples so both can participate in the process of achieving their desired pregnancy.


Preimplantation Genetic Testing (PGT) is a test performed to diagnose genetic abnormalities in embryos, to prevent the transmission of genetic diseases.


Compatibility Genetic Testing is performed on parents to prevent the transmission of genetic diseases to their future child.

Incubator Time-Lapse

It is a biological marker that allows us to identify which embryo has the best chance of implantation according to its energetic state.

Frequently Asked Questions

It is a set of techniques and treatments that aim to solve fertility problems. At WeFIV, we have a team of professionals specialized in the best procedures, as well as cutting-edge technology, to help you along this path.

At WeFIV we offer a variety of assisted reproduction treatments, including Intrauterine Insemination, In Vitro Fertilisation, egg donation and fertility preservation. Each of these treatments aims to overcome different fertility challenges.

Intrauterine Insemination is considered a low-complexity treatment and is less invasive than other assisted reproductive techniques. In this procedure, sperm, previously selected in the laboratory, is introduced into the woman’s uterus.

Assisted reproduction offers the possibility of building a family to people who face fertility problems and to people who, for different types of families, require reproductive treatments as well. In addition, thanks to vitrification, women can preserve their fertility to postpone motherhood without affecting their reproductive capacity.

The best technique depends on the individual needs and circumstances of each person or couple. For example, In Vitro Fertilisation is an option for highly complex cases, while egg donation may be the best option for women who cannot use their own eggs.

At WeFIV, the main low-complexity assisted reproduction technique we offer is Intrauterine Insemination. We also have complementary treatments that can be considered low complexity, such as certain fertility tests and techniques, which help to increase the chances of achieving a pregnancy.

These include the evaluation of semen quality, monitoring of the menstrual cycle and optimisation of the conditions for conception. Each case is unique, so the most appropriate treatment is determined according to the individual needs of each patient.
