Unité 173 INSERM, Hôpital Necker-Enfants-Malades, Paris, France.

A European survey was carried out in order to evaluate the incidence of chromosome anomalies in spontaneous abortions after IVF. Of the 34 abortuses analysed, 21 had a chromosome anomaly (62%), namely three with monosomy X,14 autosomal trisomies, one double trisomy, one triploidy, one tetraploidy and one translocation. These data show that IVF does not increase the incidence of chromosomal abortuses when compared with natural conceptions (60%).

UI	MeSH Term	Description	Entries
D007987	Gonadotropin-Releasing Hormone	A decapeptide that stimulates the synthesis and secretion of both pituitary gonadotropins, LUTEINIZING HORMONE and FOLLICLE STIMULATING HORMONE. GnRH is produced by neurons in the septum PREOPTIC AREA of the HYPOTHALAMUS and released into the pituitary portal blood, leading to stimulation of GONADOTROPHS in the ANTERIOR PITUITARY GLAND.

D008596	Menotropins	Extracts of urine from menopausal women that contain high concentrations of pituitary gonadotropins, FOLLICLE STIMULATING HORMONE and LUTEINIZING HORMONE.
