BACKGROUND A Danish population based matched case-control study of perinatal risk factors in children with infantile autism has provided some interesting and surprising observations regarding infantile autism and children born after assisted conception. METHODS AND RESULTS The cases (461) consisted of all children born between 1990 and 1999 and diagnosed with infantile autism in the Danish Ps...

Objective. To investigate the association between assisted conceptions and preeclampsia (PEC), including assessment of severity of disease. Methods. In a prospective case control study, cases were selected from women with preeclampsia and controls from women without preeclampsia. Exposure was defined as assisted conception with intrauterine insemination or in vitro fertilization (IUI or IVF). W...

This paper presents the findings of the third phase of a longitudinal study of families created by assisted reproduction. The quality of parent-child relationships was examined close to the adolescent's 18th birthday in 26 in vitro fertilization (IVF) families and 26 donor insemination (DI) families in comparison with 38 adoptive families and 63 natural conception families matched for demograph...

Comparison of assisted conception in Australia, the United Kingdom, and the United States indicates that further rapid growth in services is likely in many countries. Better data on pregnancy rates and the outcome of pregnancy, as well as standardized reporting of national results, are needed to monitor the effectiveness of treatment.

The ability to cryopreserve human oocytes and store them indefinitely would be beneficial for cancer patients at risk of becoming sterile after therapy, allow women to delay reproduction, and alleviate religious concerns associated with embryo storage. In 1986, Chen was the first to report a pregnancy originating from a frozen–thawed human oocyte. Although over 100 babies have been born from oo...

Ectopic pregnancy may be the only life-threatening disease in which prevalence has increased as mortality has declined. The most prominent theory to explain this phenomenon involves increased sensitivity of serum beta-human chorionic gonadotrophin (HCG) immunoassay and improved quality of transvaginal ultrasound, combined with a heightened awareness and increased suspicion of the condition amon...

this study had the objective of determining the fertility and calving ease of small holder indigenous cattle herds inseminated with imported semen from proven sires. sixty one indigenous cows of different breed origin (bunaji, sokoto gudali and rahaji) were selected from different herds across jigawa state-nigeria, and were used for this study. the selected dams were inseminated with semen from...

BACKGROUND There has been much debate about the effect of 'residual' LH levels in normogonadotrophic women undergoing assisted reproduction with GnRH agonist down-regulation and recombinant FSH ovarian stimulation. The aim of this prospective study, where receiver-operating characteristic (ROC) analysis was used, was to assess further the usefulness of serum LH levels as predictors of ovarian r...
