The role of cytoplasmic fragmentation in human embryo development and reproductive potential is widely recognized, albeit without standard definition nor agreed upon implication. While fragmentation is best understood to be a natural proces…

The aim of this study was to investigate if variation in endometrial thickness affects clinical pregnancy and live birth rates among patients undergoing single euploid embryo transfer (SET). A retrospective review of IVF cycles performed at…

Infertility has a prevalence of up to 16% worldwide and is on the rise in developed nations, largely due to pursuing childbearing at advanced reproductive ages. Advances in assisted reproductive technology have benefitted socioeconomically …

PURPOSE: The objective of this review is to define live birth rate (LBR) and clinical pregnancy rate (CPR) for women ≥ 40 undergoing ovulation induction (OI)/intrauterine insemination (IUI). METHODS: A systematic review was performed in ac…

PURPOSE: To determine the prevalence of allergy in couples undergoing in vitro fertilization (IVF) and the relationship between having allergy and IVF treatment outcomes. DESIGN: A retrospective cohort study of female infertility patients …

PURPOSE: In vitro fertilization (IVF) infants have lower birthweights than their peers, predisposing them to long-term health consequences. Blastocyst transfer (BT), at day 5-6 post-fertilization, is increasing in usage, partially due to im…

BACKGROUND: Singleton infants conceived using assisted reproductive technology have lower average birthweights than naturally conceived infants and are more likely to be born low birthweight (<2500 gr). Lower birthweights are associated wit…

BackgroundWhen stimulating a patient with poor ovarian response for IVF, the maximal dose of gonadotropins injected is often determined by arbitrary standards rather than a measured response. The purpose of this study was to determine if se…

BACKGROUND: To compare the outcome of IVF cycles in women receiving controlled ovarian stimulation with recFSH or recFSH plus low dose hCG. METHODS: A retrospective case control study, performed at a private practice affiliated with an aca…

Background: Endometriosis is the presence of endometrial glandular and stromal cells outside of the uterine cavity. Our previous study showed that in vitro culture of human endometrial tissue in a three-dimensional (3D) fibrin matrix could …

OBJECTIVE: To investigate the effect of a combination of letrozole and gonadotropins in advanced reproductive age infertile women who were treated with IUI. DESIGN: A retrospective case control study. SETTING: A private practice affiliate…

Introduction: Endometriosis is the presence of endometrial glandular and stromal cells outside of the uterine cavity. This disease is found in about 10% of women of the reproductive age and in up to 50% of women with infertility. Surgery co…

Endometriosis is the presence of endometrial tissue outside of the uterine cavity and is the most common gynecologic disorder in women of reproductive age. Although the quality of life for women with endometriosis is severely compromised, v…

OBJECTIVE: To determine the inhibitory effect of a statin on angiogenesis in a three-dimensional (3-D) culture of human endometrial fragments in vitro. Angiogenesis has been proposed as an important mechanism in the pathogenesis of endometr…

PROBLEM: Our previous study showed that in vitro culture of human endometrial tissue in a three-dimensional (3D) fibrin matrix could mimic the early stages of endometriosis with invasion, gland and stroma formation and sprouting of new vess…

To evaluate the effect of peritoneal fluid (PF) on preimplantation mouse embryo development and apoptosis, PF was obtained from women presenting with (n = 7) and without endometriosis (n = 7). Mouse embryos were cultured to the blastocyst s…
