The use of an embryo transfer simulator to compare transfer techniques and pregnancy outcomes among physicians.

Objective: To evaluate the association between embryo transfer techniques and pregnancy outcomes.

Design: This is a prospective observational study with a retrospective cohort.

Setting: University Clinic.

The prevalence of sporadic and recurrent pregnancy loss.

This manuscript reports on the prevalence of early pregnancy loss. The impact of improved pregnancy diagnosis and influence of increased age and body mass index at first birth are discussed.

Acupuncture increases parasympathetic tone, modulating HRV - Systematic review and meta-analysis.

Introduction: An increasing number of studies have demonstrated that acupuncture can influence Autonomic Nervous System functions. Heart Rate variability (HRV) is one widely used marker of autonomic activity. The main objective of this systematic review is to critically assess the evidence from randomized clinical trials (RCTs) regarding the effect of acupuncture on HRV as compared to placebo methods.

Embryo transfer success: It is in our hands.

Embryo transfer (ET) is considered as a critical step in the process of in vitro fertilization. Interestingly, studies have consistently shown significant outcome differences between physicians. Although the outcome of ET is not related to the physician's experience and specifically not different between fellows and attending physicians, certain techniques have been found to affect the success rate.
