Background: Study question: what is the effect of advanced aged in pregnant women using assisted reproductive technology on the rate of miscarriages? Summary answer: the advanced age effects on the rate of miscarriages. What is known already: It is well known that miscarriage risk increases with age. The proportion of women giving birth after 35 years of age has risen considerably in developing...

Fifteen states have adopted legislative mandates with an eye towards covering the costs associated with assisted reproductive technology (ART). This review summarizes the current state of ART coverage in the states in question and explores how the limits of mandated coverage constrain the access of certain infertile subjects to ART. Specifically, note is made of barriers compromising the access...

background: spontaneous occurrences of multifetal pregnancies always have been a medical problem. the risks of perinatal morbidity and mortality and maternal morbidity increase with enhancement of the number of fetuses. in our prospective experimental study, the outcome of twin pregnancy after assisted reproductive technologies (art) with and without multifetal pregnancy reduction (mfpr) is com...

objective: in vitro ovarian follicle culture provides a tool to investigate folliculogenesis and may be used as an assisted reproductive technology )art(. this study aims to compare survival and development rates in mouse ovarian follicles after two and three dimensional in vitro cultures. methods: preantral follicles were isolated from the ovaries of 14-day old female mice and cultured in α-m...

Although intracytoplasmic sperm injection (ICSI) allows proper fertilization in most cases of male sub fertility, it is one of the most unphysiological techniques in assisted reproductive technologies (ART). Thus, over the last decade, researchers have tried to improve sperm observation with higher-resolution microscopy techniques such as the intracytoplasmic morphologically selected sperm inje...

background: the use of assisted reproductive technology (art) is increasing in the world. the rate, efficacy and safety of art are very different among countries. there is an increase in the use of intra cytoplasmic sperm injection (icsi), single fresh embryo transfer (et) and frozen-thawed embryo transfer (fet). objective: the objective of this study was to compare pregnancy rate in fresh et a...

This evidence-based review focuses on the impact of potentially modifiable, non-communicable lifestyle factors on reproductive performance in the general population and the infertile population undergoing assisted reproductive technology (ART) treatment. The impact of several lifestyle factors including; age, weight, smoking, diet, exercise, psychological stress, caffeine consumption, alcohol c...

Through the use of assisted reproductive technology (ART), we will be able to extend the use of genetically superior animals, and perhaps increase the number of offspring. These technologies include such procedures as estrus synchronization, superovulation, artificial insemination, embryo transfer, in vitro fertilization (IVF), and cloning. Because they exhibit seasonal breeding and multiple ov...

Various assisted reproductive techniques have been developed and refined to obtain a large number of offspring from genetically superior animals or obtain offspring from infertile (or subfertile) animals. The embryo transfer is one assisted reproductive technique developed well, aimed at increased productivity of selected females, disease control, importation and exportation of livestock, rapid...
