Nutrition education and counselling (NEC) is a commonly applied strategy to improve maternal nutrition during pregnancy. However, with the exception special populations and specific diets, the effect of NEC on maternal, neonatal and child health outcomes has not been systematically reviewed. Using a modified Child Health Epidemiology Reference Group method ...

Heterotopic pregnancy (HP), i.e. the simultaneous development of an intrauterine and an ectopic pregnancy, is rare with a reported incidence of between 1 : 2600 and 1 : 30 000. Only a few cases have been described in the literature. We report here on an extremely rare case of HP after natural conception with cardiac ...

Placement of sperm deep in the equine uterine horn allows fewer sperm to be inseminated while maintaining acceptable fertility, and has been promoted for use in circumstances when fertility would be expected to be low if standard insemination were used (e.g., semen from a subfertile stallion, or frozen-thawed semen). Two ...

Standard semen parameters are poor predictors of fertility potential. To date, apart from, paternal karyotyping sperm factors are not evaluated in recurrent pregnancy loss (RPL), only recent studies have emphasized the role of sperm factors in early embryonic development as sperm transcribes genes critical for early embryonic development. Sperm DNA ...

As the incidence of twin gestation increases, it is important to consider the maternal risks associated with carrying multiples. Compared with singleton gestation, there are increased risks to the mother during the antepartum, intrapartum, and postpartum periods. Certain pregnancy complications are more likely to occur during a twin gestation, including ...

Exposure of the fetus to the intrauterine milieu can have profound effects on the health of the offspring in adulthood. These observations are highly reproducible in many populations worldwide although the mechanisms behind them remain elusive. The 'thrifty phenotype' hypothesis proposes that poor fetal nutrition leads to programming of metabolism ...

A woman's nutritional status should be assessed preconception with the goal of optimizing maternal, fetal, and infant health. Pregnancy-related dietary changes should begin prior to conception, with appropriate modifications across pregnancy and during lactation. The Recommended Dietary Allowances (RDAs) are levels of nutrients recommended by an expert IOM panel based ...

Varicocele is the most common and treatable cause of male infertility. Studies of a rat experimental left varicocele model and human testicular biopsy samples have shown the involvement of various factors in its pathophysiology. Among them, oxidative stress plays a major role in impairing spermatogenesis and sperm function. Therefore, in ...

We review the literature about the impact of shock wave lithotripsy (SWL) on male reproduction. Studies investigating the in vitro effect of shock waves on semen samples indicate that spermatozoa are vulnerable to SWL. According to animal studies, intratesticular bleeding is common, but pregnancy rates are not affected by shock ...

The ideal method for sperm selection during Intracytoplasmic sperm injection (ICSI) is still ill-defined. Identification of a viable spermatozoon amongst immotile spermatozoa for ICSI often becomes difficult. Ninety-six ICSI cycles were selected and divided into Group A (azoospermic, n = 58) and Group B (complete asthenozoospermic, n = 38). Oocytes having birefringent meiotic spindle ...

Several lines of evidence suggest that autoimmune mechanisms may influence the reproductive life and fertility of both sexes, commonly manifesting as infertility or pregnancy loss. Part of the controversy that characterizes this assumption derives from the overlooked suspect of autoimmune conditions in the absence of symptoms or the limited physician ...

Normal fertilization and ongoing pregnancy can be achieved using intracytoplasmic sperm injection (ICSI), even with severely immature spermatozoa. However, the published literature documents conflicting results as to the outcome of ICSI.

Maternal infection during pregnancy has been repeatedly associated with increased risk for schizophrenia. Nevertheless, most viruses do not cross the placenta; therefore, the damaging effects to the fetus appear to be related to maternal antiviral responses to infection (e.g. proinflammatory cytokines). Fetal exposure to the proinflammatory cytokine interleukin-8 (IL-8) has ...

Abstract Miscarriage is the most common type of pregnancy loss, occurring in up to 15% of clinically recognized pregnancies. Our understanding of the etiology is still limited but is believed to be multifactorial, including endocrine and anatomical abnormalities, immunologic, genetic and lifestyle factors. The aim of this study was to ...

BACKGROUND: Monozygotic (MZ) twin pregnancies are associated with increased perinatal mortality and morbidity, and risk of congenital anomalies. The causes of MZ twinning in humans are unclear but the incidence may increase after PGD, for example, as a result of holes created in the zona pellucida. We compared the incidence ...

Monozygotic twins (MZ) are rarely absolutely "identical." This review discusses the types of genetic/epigenetic and prenatal environmental post-zygotic mechanisms that cause discordance within such twin pairs. Some of these mechanisms--ranging from heterokaryotypia to skewed X-chromosome inactivation--may cause extreme discordance, but these extremes are merely the more emphatic examples of discordance ...
