Women undergoing in-vitro fertilization should have only one or two embryos transferred during the process, depending on their age, says a study published Wednesday in the British medical journal The Lancet. Transferring three or more embryos during any IVF cycle should be avoided when possible, researchers say.
Many women do not fully appreciate the consequences of delaying motherhood, and expect that assisted reproductive technologies can reverse their aged ovarian function, Yale researchers reported in a study published in a recent issue of Fertility and Sterility.
"Overall, parents underestimated their daughters' reproductive concerns," Quinn said. "The majority of adolescents reported a strong desire for future parenthood, whereas parents expected their daughters to be satisfied with survivorship."
Ninety-six per cent of women who attended a preconception clinic before undergoing IVF had three or more lifestyle problems and risk factors, according to a study in the May issue of the Journal of Advanced Nursing.
According to the European Environment Agency (EEA), household products, cosmetics, pharmaceuticals and food all contain endocrine disrupting chemicals (EDCs) which may be causing significant increases in diabetes, obesity, cancers and increasing infertility.
Scientists at the Universities of Birmingham and Warwick have shed new light on how sperm navigate the female reproductive tract, 'crawling' along the channel walls and swimming around corners; with frequent collisions.
Throughout history, infertility has mainly been seen as a female problem, but the reality is far from that. When it comes to couples trying to have a baby, infertility is evenly distributed between the sexes: 30 percent due to male problems, 30 percent female, 10 percent male and female combined and 20 percent unexplained. Age is a factor for both.
Cigarette smoke reduces the production of a Fallopian tube gene known as "BAD", which helps explain the link between smoking and ectopic pregnancy. The finding, from scientists led by Drs Andrew Horne and Colin Duncan at the Medical Research Council (MRC) Centre for Reproductive Health in Edinburgh, UK, was described at the annual meting of ESHRE (European Society of Human Reproduction and Embryology) in Istanbul.
Lifestyle advice given by doctors to men diagnosed with infertility should be radically overhauled according to research published June 13.
This potentially overturns much of the current advice given to men about how they might improve their fertility and suggests that many common lifestyle risks may not be as important as we previously thought.
