introduction: regarding to the recent advances in assisted reproductive techniques (art), twin and multiple pregnancies have increased during past years. objective: this study was performed to compare obstetrics and perinatal outcomes of dichorionic twin pregnancy following art with spontaneous pregnancy. materials and methods: in this cross-sectional study which was performed in ghaem hospital...

Background: Infertility is a complicated and psychologically threatening and challenging crisis. The rapid development of ART has raised many ethical and legal issues and lead to various emotional changes (anxiety, depression, stress, aggressiveness, etc.) as it may involve considerable time, expense, and loss of privacy. It can be both dangerous and expensive to enter the world of assisted rep...

BACKGROUND It has been suggested that couples who conceive with assisted reproductive technologies (ART) invest more in their child than those who conceive spontaneously. This study examined how parental investment in the child (PIC) varied as a function of method-of-conception, gender and other contextual variables, i.e. prenatal depression, social support and satisfaction with the marital rel...

Assisted reproductive techniques have been a great blessing for the infertile couple. Some have questioned their use, citing the unknown risk to the unborn child. The emergence of one of the newest techniques, intracytoplasmic sperm injection, has again sparked debate on the ethics of assisted reproductive techniques. Those who oppose intracytoplasmic sperm injections use are primarily concerne...

Heterotopic pregnancy is defined as intrauterine and extrauterine pregnancy entity coexisting simultaneously and which has been on the rise in recent years with the development of assisted reproductive techniques. We report 4 cases of heterotopic pregnancy, three of them resulting from assisted reproductive technologies and a spontaneous case. We also describe the methods used for diagnosis, th...

heterotopic pregnancy (hp) is the simultaneous occurrence of intra- and extrauterine pregnancies. it is a rare event in spontaneous pregnancies with an incidence of less than 1:15000 however the frequency has increased to 1% in accordance with the widespread use of assisted reproductive techniques (art). the pre-operative diagnosis of this condition is generally difficult and it would be life t...

recent advances in reproductive medicine have created a demand for more accurate and safe imaging modalities before assisted reproductive treatment(art) (1). gradually, the important role of three-dimensional (3d) ultrasonography in the diagnosis of uterine congenital anomalies has been proved (2-4).

Assisted reproductive technologies (ART) have been used successfully in humans, domestic and laboratory species for many years. In contrast, our limited knowledge of basic reproductive physiology has restricted the application of ART in companion animal, non-domestic and endangered species (CANDES). Although there are numerous benefits, and in some cases a necessity, for applying ART for the re...

New Current Procedural Terminology (CPT) codes for 2004 have been adopted for utilization with assisted reproductive technologies. It is important for professionals in the field of assisted reproductive technology (ART) to become familiar with them prior to their implementation. This document replaces the July 2002 American Society for Reproductive Medicine (ASRM) Practice Guideline Correct Cod...
