Myocardial infarction complicating the initial phase of an ovarian stimulation protocol.

Two previous reports have reported myocardial infarction during ovarian hyperstimulation syndrome, a complication of controlled ovarian stimulation characterized by ascites, pleural effusion, hemoconcentration and an increased thromboembolic risk, but no association with the initial phase (before treatment with human chorionic gonadotropin) of a normal ovarian stimulation protocol for infertility has ever been described. We report the first case, to our knowledge, of acute myocardial infarction occurring during the initial phase of an otherwise uncomplicated ovarian stimulation protocol. A young woman with infertility associated to polycystic ovary syndrome was treated with leuprolide acetate and recombinant follicle stimulating hormone to induce ovarian stimulation for in vitro fertilization and embryo transfer.

Natural cycle as first approach in aged patients with elevated follicle-stimulating hormone undergoing intracytoplasmic sperm injection: a pilot study.

Background: Poor ovarian response to standard in vitro fertilization-embryo transfer (IVF-ET) protocols or different regimens of treatment, as consequence of a diminished ovarian reserve, correlates strictly with patient age, elevated follicle-stimulating hormone (FSH) and reduced antral follicle count. The aim of the present pilot study was to evaluate the outcome of patients with poor prognostic features undergoing IVF-ET with natural cycles as a first approach and not as a consequence of a previous failure treatment.

Materials And Methods: Eighteen aged patients (mean +/- standard deviation 40.

Gonadotropin-releasing hormone antagonist and metformin for treatment of polycystic ovary syndrome patients undergoing in vitro fertilization-embryo transfer.

Aim: The combination of gonadotropin-releasing hormone (GnRH) antagonist and gonadotropin represents a valid alternative to the classical protocol with GnRH agonist for ovulation induction in patients with polycystic ovary syndrome (PCOS). The use of metformin is of benefit to women with PCOS. The aim of the present study was to compare the stimulation characteristics and in vitro fertilization (IVF)-embryo transfer (ET) outcomes of the standard short GnRH antagonist protocol for ovarian stimulation with or without metformin.

Pathologic findings in hysteroscopy before in vitro fertilization-embryo transfer (IVF-ET).

Background: The aim of this study was to evaluate hysteroscopy routinely performed prior to in vitro fertilization-embryo transfer (IVF-ET).

Methods: We analyzed in a prospective study 300 patients who underwent hysteroscopy before the first IVF-ET cycle. We analyzed then in a retrospective manner 300 patients who did not perform hysteroscopy.

Consecutive cycles in in vitro fertilization--embryo transfer.

Background: The decline of female fertility with advancing age is well documented. The aim of this study was to compare the ovarian performance after repeated ovarian stimulation cycles in women of different ages.

Methods: Four hundred patients who started at least three in vitro fertilization (IVF) cycles during the 5-year period between 1998 and 2002 were identified.
