Treballs Finals de Grau de Nutrició Humana i Dietètica, Facultat de Farmàcia i Ciències de l'Alimentació, Campus de l'Alimentació de Torribera, Universitat de Barcelona. Curs: 2019-2020.

The main strategy to treat it is the use of ART (Assisted Reproductive Technology), which has a huge impact and economic, emotional and psychologic costs on society. It is because of this that other approaches are being studied to prevent infertility and help improve the fertility taxes, with a special focus on promoting changes in both lifestyle and nutrition patterns.

Further investigations are needed to clarify the topic and elaborate specific recommendations and clinical guidelines to boost fertility. ; [cat] La infertilitat és una patologia que actualment afecta a nivell mundial a 1 de cada 6 ciutadans en la seva etapa fèrtil.
