Reproduction is the process by which offspring are formed and genetic material is passed on from one generation to the next. In humans, reproduction is sexual.
New technique could save cancer patients’ fertility — Researchers grow immature human egg cells to nearly mature egg in laboratory. – Researchers have successfully grown a woman’s immature egg cells, contained in a tiny sac called a follicle, to a healthy and nearly mature egg in the laboratory. When an egg is fully mature, it is ready to be fertilized.
A substantial number of European patients travel to other countries for fertility treatment — Who goes abroad for fertility treatment and why? – Many European patients are travelling to other countries for fertility treatment, revealed by researchers at the 25th annual conference of the European Society of Human Reproduction and Embryology.
High levels of cycling training damage triathletes’ sperm – Cycling training may have a major impact on sperm morphology, as researchers have proved this fact in triathletes who have high intensity cycling training during thrie career.
Complications early in pregnancy or in previous pregnancies adversely affect existing or subsequent pregnancies – Complications in early pregnancy or in previous pregnancies can predict the likelihood of further problems in current or subsequent pregnancies, revealed by researchers.
Worldwide report shows increase in assisted reproduction: 250,000 babies (approximately) born in 1 year – Assisted reproductive technology (ART) is responsible for an estimated 219,000 to 246,000 babies born each year worldwide according to an international study.
2 studies: The first finds twins born after fertility treatment have a higher risk of problems. A second study study finds reassuring evidence on the outcome of children born after embryo freezing. – Twins born as a result of assisted reproductive technology (ART) are more likely to be admitted to neonatal intensive care and to be hospitalised in their first three years of life than spontaneously conceived twins, according to new research in Europe’s leading reproductive medicine journal Human Reproduction.
Exposure to perfluorinated chemicals may reduce women’s fertility – Researchers have found the first evidence that perfluorinated chemicals (PFCs) ? chemicals that are widely used in everyday items such as food packaging, pesticides, clothing, upholstery, carpets and personal care products ? may be associated with infertility in women.
National Birth Defects Prevention Study Shows Assisted Reproductive Technology is Associated with an Increased Risk of Certain Birth Defects – Infants conceived with Assisted Reproductive Technology (ART) are two to four times more likely to have certain types of birth defects than children conceived naturally, according to a study by the CDC.
Depression during pregnancy can double risk of preterm delivery. Study of 791 women finds preterm delivery risk grows with severity of depression. – Depressed pregnant women have twice the risk of preterm delivery than pregnant women with no symptoms of depression, according to a new study by the Kaiser Permanente Division of Research.
Diet can strongly influence how long you live and reproduce, but now scientists have discovered that what works best for males may not be best for females. – Gender plays a major role in determining which diet is better suited to promoting longer life or reproductive success, revealed by researchers from the University of New South Wales, the University of Sydney and Massey University.
Couples with fertility problems where the man is over 35 have increased difficulty in conceiving – Pregnancy rates decrease and miscarriages increase when a father is over 35 years of age, a scientist will tell the 24th annual conference of the European Society of Human Reproduction and Embryology on Monday 7 July.
DNA fingerprinting is a very useful technique for discriminating between viable and non-viable blastocysts. Research could lead to improved pregnancy rates and fewer multiple pregnancies. – Fertility researchers have used DNA fingerprinting for the first time to identify which embryos have implanted after in vitro fertilisation (IVF) and developed successfully to result in the births of healthy babies.
