BACKGROUND Studies on the risk of chromosomal abnormalities in early spontaneous abortion after assisted reproductive technology (ART) are relatively controversial and insufficient. Thus, to obtain a more precise evaluation of the risk of embryonic chromosomal abnormalities in first-trimester miscarriage after ART, we performed a meta-analysis of all available case-control studies relating to t...

Successful pregnancy is characterized by a shift toward Th2 type immune response and suppression of adaptive immune responses to ensure acceptance of the semi-allogenic fetal graft. Also the innate immune system plays a major role during pregnancy. Recurrent miscarriage is defined as three or more consecutive pregnancy losses. About 1% of all women will suffer recurrent miscarriage. The causes ...

Objective Chlamydia trachomatis (CT) infection is the most common sexually transmitted disease in the world that can persist and also ascend in the genital tract. This intracellular and silent infection is related to some adverse pregnancy outcomes, such as miscarriage. The aims of this study were to explore the best CT screening tests using blood and vaginal samples and to investigate the corr...

CONTEXT Several sperm retrieval techniques are available for use on azoospeermic men. Comparisons between spermatozoa retrieved from the testicles and epididymis in relation to pregnancy and miscarriage rates are not well established. OBJECTIVE To compare pregnancy and miscarriage rates using sperm retrieved from the testes and epididymis using intracytoplasmic sperm injection. Furthermore, w...

BACKGROUND Threatened miscarriage is a common complication of early pregnancy increasing the risk of miscarriage or premature labour. Currently there is limited evidence to recommend any biomedical pharmacological or self-care management, resulting in a 'watchful waiting' approach. The objective of this study was to examine the feasibility of offering acupuncture as a therapeutic treatment for ...

BACKGROUND Pregnant women with a history of acquired thrombotic thrombocytopenic purpura (TTP) are considered at risk for disease recurrence and might be at risk for miscarriage, similar to other autoimmune disorders. However, the exact entity of these risks and their causes are unknown. The aim of this study was to evaluate risk factors associated with adverse pregnancy outcome, in terms of bo...

BACKGROUND The purpose of this study was to quantify spontaneous first trimester miscarriage rates per woman among parous women. A vast amount of data has accumulated regarding miscarriage rates per recognized pregnancy as well as about recurrent miscarriage. This is the second study of miscarriage rates per woman in a parous population and the first study of recurrent and non-recurrent, sponta...

OBJECTIVE To assess the fetal loss rate following amniocentesis and chorionic villus sampling (CVS). METHODS This was a national registry-based cohort study, including all singleton pregnant women who had an amniocentesis (n = 32 852) or CVS (n = 31 355) in Denmark between 1996 and 2006. Personal registration numbers of women having had an amniocentesis or a CVS were retrieved from the Danish...
