Our objective was to analyze the risk factors, stimulation characteristics, and future fecundity of patients with ectopic pregnancies after in vitro fertilization (IVF). We retrospectively evaluated all cases of ectopic pregnancy occurring between January 1989 and March 1993 (Cornell series 1 to 17). A case-control group of intrauterine pregnancies was used(More)
OBJECTIVE Chlamydia trachomatis infections of the female genital tract, although a major cause of infertility, are often asymptomatic and undetected. Since many infertile women now seek in vitro fertilization, a procedure whereby fertilization and embryo implantation are precisely timed, we sought to determine the relation between an unsuspected C.(More)

The structure of E.coli soluble inorganic pyrophosphatase has been refined at 2.7 A resolution to an R-factor of 20.9%. The overall fold of the molecule is essentially the same as yeast pyrophosphatase, except that yeast pyrophosphatase is longer at both the N- and C-termini. Escherichia coli pyrophosphatase is a mixed alpha + beta protein with a(More)
BACKGROUND Infertility is a common manifestation of the polycystic ovary syndrome (PCOS), a condition characterized by chronic anovulation, hyperinsulinemia and hyperandrogenism. Hyperinsulinemia leads to increased ovarian androgen production, resulting in follicular atresia and anovulation. Metformin, a medication that improves insulin sensitivity and(More)

Monoamniotic twins are rare, with a double survival rate of only 40%. Congenital anomalies, while more common among twins in general, are particularly common in monoamniotic twins, with the increase principally the result of structural defects. Discordant phenotypes have been reported, but a malformation of the external ear in one twin has not. In a case of(More)
