[Aspects of scientific research and technical progress in human fertility]

The development of an outstanding in vitro fertilization program greatly benefits from the contribution of research because it remains an unfailing source of questions on human reproduction, as much in the fields of physiology and pathology as in those of psychology and sociology. This paper shows five major themes that are tackled by the laboratory of biology and psychology of human fertility and the Fertility Clinic, whether it's endocrinology (the ovarian renin and angiotensin regulation), cellular metabolism (embryo metabolism), genetics (preimplantation genetic diagnosis) or cancerology (ovarian tissue conservation before or after chemo- or radiotherapy), all of these are crossed by the fifth (the psychological and ethical aspects of in vitro fertilization) which gives a human dimension to the biological work, since it's a very special biology that it's our own reproduction, the very base of the specie's survival.
