Babies conceived through in-vitro fertilization (IVF) or test tubes might be just as healthy as those conceived naturally, a new study says. Researchers from the University of Groningen, The Netherlands, said that contrary to popular belief, the IVF treatment does not increase the risk of developmental problems during early infancy.

Lead researcher Dr. Karin Middelburg said the study assessed spontaneous movements, known as general movements, in 125 infants conceived following IVF at three months of age and compared then with a control group of 90 babies born naturally to sub-fertile couples. Sub-fertile couples are those who were referred to the fertility clinic for fertility evaluation or treatment

A new study shows that a man's fertility starts to fall in his mid 30s and it could also be considered a factor in determining the reason for failed conception in couples who are trying to conceive.

Researchers from Paris studied more than 12,000 couples undergoing fertility treatments and the results revealed that pregnancy rates drop and miscarriages increase when the father is older than 40. The findings are being presented Monday at the 24th annual conference of the European Society of Human Reproduction and Embryology in Barcelona, Spain

Green tea appears to have a short-term health benefits on the large arteries of the heart, a Greek study has shown. The study found that the consumption of green tea rapidly improves the function of (endothelial) cells lining the circulatory system; endothelial dysfunction is a key event in the progression of atherosclerosis.

The study by Dr. Nikolaos Alexopoulos and colleagues in the cardiology department of Athens Medical School found that green tea rapidly improves the function of endothelial cells lining the suggests endothelium-dependent brachial artery dilatation increased significantly after drinking green tea

Screening young athletes who participate in competitive sports for potentially fatal heart problems before they compete could save lives, a study has concluded.

The new study recommends performing the electrocardiogram (ECG), which records heart activity, while exercising because that can diagnose four times as many abnormalities as while resting. The study found that a large number of previously healthy people collapse and die from undiagnosed heart abnormalities, such as sudden cardiac arrest on the playing ground

Women receiving kidneys from males donors are at a higher risk of organ rejection than those who received one from another woman, a new Swiss study says. Researchers now recommend that the gender of patients and donors should be considered in future operations to avoid such problems.

Researchers at University Hospital Basel analyzed data on 195,516 people in Europe who received kidneys from deceased donors between 1985 and 2004, and found that gender can substantially affect whether the operation will be successful
