An early and accurate diagnosis of reproductive dysfunctions or aberrations is crucial to better reproductive management in livestock. High reproductive efficiency is a prerequisite for high life-time production in dairy animals. Early pregnancy diagnosis is key to shorten the calving interval through early identification of open animals and their timely treatment and rebreeding so as to mainta...

BACKGROUND The literature contains reports of 2309 pregnancies in some 1600 women who have undergone renal transplantation. Certain pre-pregnancy factors, especially hypertension, renal graft dysfunction, short interval between transplant and pregnancy, and high immunosuppressive drug dosage, appear to increase the neonatal risks. METHOD We describe the outcome of 42 pregnancies in 27 allogra...

BACKGROUND It is unclear whether having a Caesarean section results in fewer subsequent pregnancies with longer intervals between pregnancies, an effect which may impact on the reproductive performance of a population. Our aim was to determine the implications of a Caesarean section on the subsequent fecundity and interpregnancy interval. METHODS This is a cohort study. The obstetric follow-u...

Background & aim: Pre-pregnancy obesity is considered as a significant predictor for neonatal and maternal morbidity and mortality. Several studies have indicated conflicting associations between body mass index (BMI) and pregnancy outcomes. This study aimed to evaluate the effects of pre-pregnancy BMI on adverse pregnancy outcomes. Methods:Thiscohort study was conducted from 2010 to 2013 in Qa...

During the last 10 years the U.S. dairy industry has experienced a reversal of the decades-long trend in declining fertility traits. In fact, there is evidence that, nationally, this is contributing to improvements in pregnancy rates. And while these measures are still close to their historical lows, there is reason for optimism that this reversal will continue into the future. The reasons for ...

OBJECTIVES We examined abruption risk in relation to change in paternity, and evaluated if birth interval confounds this association. SETTING Population-based study of singleton births in Norway between 1967 and 2009. PARTICIPANTS Women who had their first two (n=747 566) singleton births in the Norwegian Medical Birth Registry. The associations between partner change between pregnancies an...
