Abstract
A fertilization method wherein an oocyte puncture is performed and one or more oocytes are inserted into a container containing a culture medium having no added air or CO.sub.2 and intended for the fertilization and culture of the oocyte(s), as well as spermatozoa, whereafter the container is sealed and inserted into the vagina or uterus to allow fertilization of the oocyte(s) and culture of the embryo(s). The method is characterized in that it is performed without stimulating the cycle, with LH supervision by means of blood assays, and by programming the oocyte puncture according to the LH value. The container may be kept at a temperature of approximately 37.degree. C. for 2 to 6 hours for maturation before being inserted into the vagina.
