He graduated from the Complutense University of Madrid in Medicine and he completed his training in Gynecology and Obstetrics at the Autonoma University in Madrid.

He went on to pursue a pre-doctoral training in invitro oocyte maturation at John Eppig’s laboratory (Bar Harbour, Maine, USA) and finally he achieved his PhD in Medicine from Rey Juan Carlos University in Madrid. Dr. Requena completed his training by studying several masters: Management Development at ESADE Business School, Management Program in Health Institutions at IESE Business School and Innovation and Leadership in Fertility in IE Business School.

He has participated as a tutor in several projects financed by public entities, such as “Influence of glucose metabolism during oocyte maturation in cellular apoptosis. Clinical application in the diabeticpatient” at Autonoma University in Madrid.

He is active in the Spanish Society of Fertility (SEF) and also attends the European Society of Human Reproduction and Embryology (ESHRE).
Dr. Requena has been invited to speak nationally and internationally and has authored and contributed in over 40 peer reviewed publications, published chapters and abstracts. He also serves as Ad Hoc Reviewer for the Reproductive Biomedicine Online, Human Reproduction, Fertility and
Sterility, and as the editor for a textbook on Reproductive Medicine. His research interests include Endocrinology, Ovarian Stimulations, and genetics in Reproductive Medicine.
