INTRODUCTION Ovarian Hyperstimulation Syndrome is a complication of controlled ovarian hyperstimulation during cycles of Assisted Medical Reproduction. The objective of this work was to analyze those cycles to achieve a better knowledge of this pathology, namely risk factors and strategies for prevention and treatment of Ovarian Hyperstimulation Syndrome. MATERIALS AND METHODS Retrospective a...

Controlled ovarian hyperstimulation (COH) affects adversely implantation following in vitro fertilization and embryo transfer. COH with gonadotropins alters endometrial receptivity and luteal function. In addition periovulatory endometrial characteristics in stimulated cycles are considerably different compared with the natural cycles, and periovulatory secretory transformation is consistently ...

To assess the effect of local injury to the endometrium for implantation, pregnancy and live birth rates in ICSI –ET cycles with recurrent implantation failure. The study was prospectively designed and performed in a university hospital. A group of 100 women, who failed to conceive during one or more cycles of IVF and embryo transfer (ET), was treated with a long protocol for controlled ovarian...

despite the availability of various alkaline phosphatase (alp) isoenzymes, the calf enzyme is being used in current enzyme assays as the detector enzyme. the glycosylation pattern of this enzyme makes it a suitable ligand for binding to wheat germ agglutinin lectin (wga). as a result of this property, the enzyme can not be used as a conjugate with this lectin, and the calf enzyme conjugates can...

the main role of cumulus cells (cc) is to provide nutritious materials for developing oocytes. follicular fluid (ff) contains the enzyme acid phosphatase, which plays a role in ovulation and fertilization of oocyte. the objective of this prospective study was to evaluate the levels of acid phosphatase in ff and the rate of apoptosis in cc of fertilized and unfertilized oocytes in intracytoplasm...

Many protocols have been proposed to improve IVF outcomes for poor ovarian responders. The aim of this study was to explore the relationship between age, ovarian hyperstimulation protocol and IVF/ICSI outcomes in poor ovarian responder (POR) according to the Bologna criteria, and to compare the efficacy of different protocols used in PORs undergoing IVF/ICSI. We retrospectively analyzed clinica...

background: the aim of this study was to determine the correlation between ultrastructural studies for pinopodes expression after ovarian hyperstimulation and progesterone injection in mice. materials and methods: adult nmri mice were superovulated using human menopasual gonadotropic (hmg) and human chorionic gonadotropic (hcg) hormones; after that, daily injection of progesterone (1 mg/mouse) ...

Objective(s): Progestrone is a prequisite for pre-implantation angiogenesis and induce decidual angiogenesis. It is unknown the effect of progestrone administration on the endometrium of hyperstimulated mice at pre-implantation time. Material and Methods: Adult female NMRI mice were divided in three groups [control group, ovarian stimulated group and progestrone treated mice after ovarian stimu...
