Single embryo transfer reduces the risk of  perinatal mortality in IVF

Single embryo transfer reduces the risk of perinatal mortality in IVF

ScienceDaily (July 4, 2012) — A policy of single embryo transfer (SET) reduces the risk of perinatal mortality in infants born as a result of IVF and ICSI. The conclusion emerged from an analysis of more than 50,000 births recorded in the Australian and New Zealand Assisted Reproduction Technology Database between 2004 and 2008, where the introduction of an SET policy has been associated with a reduction in overall perinatal mortality for IVF and ICSI babies Continue reading

World’s number of IVF and ICSI babies has now reached a calculated total of 5 million

World’s number of IVF and ICSI babies has now reached a calculated total of 5 million

ScienceDaily (July 2, 2012) — The number of babies born as a result of assisted reproduction technologies (ART) has reached an estimated total of 5 million since the world’s first, Louise Brown, was born in July 1978. The figures were presented at the 28th annual meeting of ESHRE (European Society of Human Reproduction and Embryology), which began 1st July, in Istanbul, Turkey. The calculation was made for a presentation at the congress from ICMART (International Committee for Monitoring Assisted Reproductive Technologies) and was based on the number of IVF and ICSI treatment cycles recorded worldwide up to 2008 with estimations added for the following three years Continue reading

Fatty diets may be associated with reduced semen quality

Fatty diets may be associated with reduced semen quality

ScienceDaily (Mar. 13, 2012) — Men’s diets, in particular the amount and type of different fats they eat, could be associated with their semen quality according to the results of a study published online in the journal Human Reproduction. The study of 99 men in the USA found an association between a high total fat intake and lower total sperm count and concentration Continue reading
