background: anti-mullerian hormone (amh) levels may represent the ovarian follicular pool and could be a useful marker of ovarian reserve. the clinical application of amh measurement has been proposed in the prediction of quantitative and qualitative aspects in assisted reproductive technologies. objective: this study aimed to assess the relationship between the serum levels of amh and results ...
Rapid development in assisted reproductive techniques along with relieving the pain of childlessness has brought new ethical and policy dilemmas. Posthumous assisted reproduction is the most challenging, difficult and sensitive issue to be discussed ethically and religiously. In this paper the acceptability of the posthumous reproduction in Islamic contexts is evaluated and major concerns like ...
Velazquez MA. Assisted Reproductive Technologies in Cattle: Applications in Livestock Production, Biomedical Research and Conservation Biology. ARBS Annu Rev Biomed Sci 2008;10:36-62. In cattle, assisted reproductive technologies (ART) can be defined as techniques that manipulate reproductive-related events and/or structures to achieve pregnancy with the final goal of producing healthy offsprin...
objective: to verify the hypothesis that the incidence of chromosomal abnormalities increases in babies conceived by different assisted reproduction procedures. the availability of the umbilical cord blood encouraged us to study this hypothesis via this method. materials and methods: this is a descriptive study, umbilical cord blood samples of assisted reproductive technology (art) children wer...
This Article discusses potential policies regarding assisted reproductive technologies (ARTs). The initial question is whether ARTs should be viewed as private matters or as issues that affect overall social good. The author explains that this question may be answered by the Supreme Court’s interpretation of the principles of procreative liberty. He then examines Supreme Court decisions regardi...
background: pentoxifylline (px) is a methyl xanthine derivative that influences the sperm motion characteristics and l-carnitine (l-c) is an amino acid that is naturally produced in the body. in general, separate administration of px and l-c has been reported to be effective on preserving sperm motility in vitro, and also when is consumed orally by the idiopathic oligoasthenoteratozoospermia (i...
در طی دهه های گذشته، درمانهای پزشکی برای برطرف کردن علل ناباروری تغییر و تحول چشم گیری پیدا کرده است. به مجموع این روشهای درمانی، فناوری کمک باروری یا assisted reproductive technology(art) اطلاق می شود. اولین شکل art که هنوز هم رایج ترین نوع آن محسوب می شود، لقاح آزمایشگاهی (in vitro fertilization) یا ivf می باشد. در روش ivf استاندارد، هر تخمک با 100 - 50 هزار اسپرم متحرک به مدت 18-12 ساعت در ...

Assisted reproductive techniques (ART) have become part of the routine care, with a preva‐ lence ranging from 0.1 to 3.9% of all live born children in Europe and an average of 2% in some parts of the USA [1]. Despite the initial dramatic improvements in success rates and significant increments in ART uptake, the live birth rate resulting from these techniques has recently plateaued. Unfortunate...
BACKGROUND Public interest in Assisted Reproductive Technology (ART) has remained high since the birth of the world's first in vitro fertilization baby, Louise Brown, in the United Kingdom. ART allows scientists to manipulate the fertilization process in order to bypass some pathological obstacles such as blocked fallopian tubes and non-functioning ovaries in the females, and blocked vas defere...
