Is time since vasectomy more important as prognostic factor for pregnancy and live birth than female and laboratory variables when treating vasectomised man using ICSI?

Fatherhood after vasectomy can be done by vasectomy reversal or intracytoplasmic sperm injection (ICSI). Time since vasectomy is the best predictive factor for patency and live birth after a vasectomy reversal but has uncertain importance after ICSI with sperm retrieval. The present study examines the influence of male, female and laboratory variables on pregnancy and live birth.

Biological effects and dose-response assessment of diesel exhaust particles on in vitro early embryo development in mice.

An increased risk of early pregnancy loss in women briefly exposed to high levels of ambient particulate matter during the preconceptional period was recently observed. The effects of this exposure on early embryo development are unknown. This study was designed to assess the dose-response and biological effects of diesel exhaust particles (DEP) on in vitro embryo development using the in vitro fertilization (IVF) mouse model.

Impact of short-term preconceptional exposure to particulate air pollution on treatment outcome in couples undergoing in vitro fertilization and embryo transfer (IVF/ET).

Purpose: To assess the potential effects of short-term exposure to particulate air pollution during follicular phase on clinical, laboratory, and pregnancy outcomes of women undergoing IVF/ET.

Methods: Retrospective cohort study of 400 first IVF/ET cycles of women exposed to ambient particulate matter during follicular phase. Particulate matter (PM) was categorized into quartiles (Q(1): < or =30.

Effects of exposure to high levels of particulate air pollution during the follicular phase of the conception cycle on pregnancy outcome in couples undergoing in vitro fertilization and embryo transfer.

The objective of this retrospective cohort study was to assess the potential effects of preconceptional short-term exposure to particulate air pollution in a real-world situation on pregnancy outcome in infertile women evaluating the possible role of IVF/embryo transfer treatment on this outcome using women who had conceived naturally for the first time during the same time frame as a matched control group. The study provides evidence for an association between brief exposure to high levels of ambient particulate matter (aerodynamic diameter View Article and Find Full Text PDF

In vitro fertilization, embryo development, and cell lineage segregation after pre- and/or postnatal exposure of female mice to ambient fine particulate matter.

Objective: To evaluate effects of pre- and/or postnatal exposure to ambient fine particulate matter on fertilization, embryo development, and cell lineage segregation in preimplantation blastocysts using the IVF mouse model.

Design: Animal model.

Setting: Academic institution.

Comparison of the efficacy of two commercially available media for culturing one-cell embryos in the in vitro fertilization mouse model.

Objective: To examine the effects of two commercial media on the development of mouse ova fertilized in vitro to the blastocyst stage.

Design: Animal model.

Setting: Academic institution.
