All current approaches to manipulating the reproductive biology of the nonpregnant mare are discussed.

background & aim: stress and anxiety due to waiting for treatment results and uncertainty of treatment success are common problems in infertile women. acupuncture has been suggested as an effective strategy to relieve anxiety. this study aimed to review the available evidence on the effects of acupuncture on anxiety in infertile women. methods: this systematic review was conducted via searching...

introduction: combination of congenital diaphragmatic hernia (cdh) and anorectal malformation (arm) is rare. in this report, we describe a combination of imperforate anus and cdh in one of twins who conceived by assisted reproductive technology (art). case report: a female preterm newborn at 27 weeks of gestation was referred to our neonatal intensive care unit due to respiratory distress. she ...

background: the retrieval of good quality oocytes that is accomplished with selection of the best induction ovulation protocol on the basis of patients condition, age and cause of infertility, is one of the most important aspects of art cycles. the objective was to evaluate the efficacy of low dose, long acting gnrh-a (decapeptyle) for pituitary desensitization and outcome of art compared to lo...

Background The best time of final oocyte maturation triggering in assisted reproduction technology protocols is unknown. This time always estimated by combined follicular size and blood progesterone level. Objective The aim of this study was evaluation of the effect of delaying oocyte maturation triggering by 24 hr on the number of mature oocytes (MII) and other in vitro fertilization cycle c...

The use of modern reproductive technology, such as in-vitro fertilization and its related procedures, has opened new areas of legal, religious and public concern. Thirty years ago, the development of effective methods to control procreation generated a debate on whether couples had the right to enjoy sex in the absence of its procreative effect. Today, assisted reproductive technology (ART) all...

A matched follow-up study design was used to test the hypothesis that pregnancy rates following assisted reproduction procedures do not differ between women with or without intramural or sub-serosal uterine leiomyomas. Women undergoing their first in-vitro fertilization (IVF)-embryo transfer or zygote intra-Fallopian transfer (ZIFT) cycle between January 1993 and June 1995 were included. Cases ...

BACKGROUND Growth hormone (GH) is required for ovarian follicular development, and its administration during ovarian stimulation improves pregnancy rate in cow and sheep. Data on the use of exogenous GH in human assisted reproduction treatment are inconsistent. This prospective randomized study evaluates the usefulness of GH administration in women of >40 years undergoing ovarian stimulation fo...

During the last few decades in vitro production of mammalian embryos and assisted reproductive technologies such as embryo transfer, cryopreservation, and cloning have been used to produce and propagate genetically superior livestock. However, efficiencies of these technologies remain low. For these technologies to become more commercially viable, the efficiencies must improve. Despite this imp...

Biological technology used for purposes of human reproduction has generated a number of issues involving contract law, genetic parenthood, and public policy. One such issue arises from disagreements about the fate of frozen embryos. This issue presents special challenges to the judicial process even though historically courts have had experience in applying reason to the most emotional of issue...
