Biomedical care in fertility disorders has gained recognition as has the diagnosis and treatment of a disease, infertility, where an essential biological function to achieve a life plan is impaired. Taking this into consideration, since 1995, the diagnosis and treatment of infertility has been included as a basic benefit within the Catalog of Services of the National Health System (Royal Degree 63/1995, 20 January, health benefits under the social security program).

The overall objective is to carry out research in a multidisciplinary group, and to combine collective expertise to extend knowledge of the loss of fertility observed in our society, as well as to offer preventive, diagnostic and therapeutic solutions that will either minimize the impact of this disorder or successfully overcome it.

Epidemiological research aims to analyze various air pollutants and environmental factors and assess their impact on reproductive outcomes, including sperm quality, which may lead to guidelines for the prevention or reduction of human exposure to environmental pollutants.

Clinical research in human model will allow us to assess strategies that may potentially improve reproductive functions and thereby increase live birth rate when ART are required.

Evidence Based Medicine research: We collaborate with the Cochrane Gynecology and Fertility group evaluating the evidence in reproductive medicine in international studies. We aim to develop translational recommendations for best clinic practice.
