Today it is possible to make the dreams of thousands of couples trying to have a baby of their own come true, bypassing significant conception hurdles. In a time when subfertility problems keep rising and fertility rates in the western world are in decline, scientific research has brought about a revolution with the development of Assisted Reproduction Technologies (ART), offering us the ability to treat the majority of subfertility cases. Until now more than 1.5 million children have been born with this method worldwide. This website intends to present the scientific background on issues related with human reproduction and ART in simple terms. For practical reasons it has been divided in two parts: a short one and a more extensive one. The following sections will provide a comprehensive overview of the anatomy and function of the female reproductive system, the physiological procedure of conception, causes of subfertility and recent methods for their diagnosis and treatment.
