BACKGROUND Reproductive outcome studies of couples with a history of recurrent pregnancy loss (RPL) associated with a maternal or paternal carrier of a structural chromosome rearrangement are limited. Correlation of carrier status and cytogenetics of miscarriage specimens is critical to estimate subsequent pregnancy outcome. METHODS Couples found to have a structural chromosome rearrangement ...

BACKGROUND This study takes an in depth look at embryonic development, implantation, pregnancy and live birth rates with frozen epididymal and testicular sperm from obstructed (OA) and non-obstructed (NOA) patients. METHODS Paternal effect of sperm source on zygote formation, embryonic cleavage, and genomic activation were examined. Additional outcome parameters monitored were clinical pregna...

The effect of heparin on IVF outcome has been widely debated in the literature.

Searches were conducted on MEDLINE, EMBASE, Cochrane Library and Web of Science and identified 10 relevant studies (five observational and five randomized) comprising 1217 and 7...

OBJECTIVE To determine the relationship between paternal body mass index (BMI), embryo development and pregnancy, and live birth outcomes after assisted reproductive technology (ART). DESIGN Retrospective analysis of ART cycles. SETTING Major assisted reproduction center. PATIENT(S) Three hundred five couples undergoing ART in a private fertility clinic. INTERVENTION(S) No intervention ...

BACKGROUND Human exposure to phenols, including bisphenol A and parabens, is widespread. Evidence suggests that paternal exposure to environmental chemicals may adversely affect reproductive outcomes.

Objective: Microsurgical reconstruction is recommended for obstructions in the vas deferens and epididymis. However, intracytoplasmic sperm injection (ICSI) is the preferred therapy and microsurgical vasoepididymostomy (MVE) may be neglected for patients with epididymal obstruction. Fertility outcomes from large sample are absent. In this study we aimed to investigate the pregnancy and live bir...
