background: sacrococcygeal teratoma (sct) is a rare congenital tumor and its association with ivf pregnancy is not clear. there are limited reports of congenital tumors in ivf pregnancy. the exact embryogenesis of sct is not known but a genetic etiology has been reported. whether these congenital tumors have any association with assisted reproductive techniques remains obscure. case presentatio...

pelvic inflammatory disease (pid) is a rare complication of transvaginal oocyte retrieval. it may result in failure of assisted reproductive techniques (art). during a 7 years period, 5958 transvaginal ultrasound-guided oocyte retrievals resulted in 10 cases of acute pid. eight out of 10 patients were diagnosed infertile because of endometriosis. two patients had mild ovarian, 3 had stage iii, ...

Assisted reproductive technologies (ARTs) have become almost commonplace in the developed world. It is estimated that 1% of American children are now conceived using some form of assisted reproduction, and that over a million children have been born as a result of the use of ARTs. In the past several years, however, scientists have begun to sound a cautionary note about the health outcomes of A...

Now-a-days the assisted reproductive technologies (ART) are progressing and advancing rapidly. Many reproductive medicine specialists do believe in ART to be the first choice for infertile women regardless of age related issues while gynecologists do believe in reproductive surgery as basic treatment option for these patients. Debate is still unsolved between reproductive surgery or ART which i...

Assisted reproductive technologies (ARTs) can be very helpful for certain patients, but ethical concerns have been raised about the inherent nature of specific techniques and the contexts in which many techniques are used. Physicians play important roles in supporting those who wish to become parents and in educating patients about impediments to fertilization and way to promote conception. We ...

The International Committee Monitoring Assisted Reproductive Technologies (ICMART) is an independent, international non-profit organization that has taken a leading role in the development, collection and dissemination of worldwide data on ART. Information on availability, efficacy and safety is provided to health professionals, health authorities and the public. The glossary facilitates dissem...

A giant amphiphile, which is constructed with an amorphous nano-pyramid (triphenylamine, TPA) and a crystalline nano-sphere (C60), was synthesized. Structural characterization indicates that this pyramid-sphere-shaped amphiphile (TPA-C60 ) forms a solvent-induced ordered phase, in which the two constituent units self-assemble into alternating stacks of two-dimensional (2D) TPA and C60 nano-shee...

We exploit the timing of the Cuban Missile Crisis and the geographical variation in mortality risks individuals faced across states to analyze reproduction decisions. The results of a difference-in-differences approach show evidence that fertility increased in states that are geographically closer to Cuba and states with more military installations. The findings suggest that when facing high mo...
