The first fraction of ejaculate is the most effective for conception
25 May 2015 10:20

Sperm in the first fraction of ejaculate are more numerous, move more and present better quality DNA than those lagging behind. This is the conclusion of a study led by the Ginemed fertility clinic, which confirms that while the objective of the first fraction is to fertilise the egg, the second phase is so that no sperm from any other male has a chance to fertilise it.

Insemination has a success rate of 17.5% per cycle when using the partner’s sperm
Uterine contractions increase the success of artificial insemination
24 November 2014 10:05

The negative impact of contractions during in vitro fertilisation is a well-known fact. What was unknown until now was the effect it had on artificial insemination. A new study has discovered that it is the contrary to that seen in embryo transfer: there is an improved chance of getting pregnant.

Suffering from breast cancer increases the risk of another tumour by 39%
16 October 2013 10:39

Women diagnosed with invasive breast cancer are 39% more likely to develop a second cancer in a different part of the body. Such is the conclusion of a recent study, pioneered by female Spanish researchers. The study suggests that this increased risk could be due to the similar risk factors involved in both cancers, or to the side effects of the treatment received by breast cáncer patients.

Tobacco and excess weight: two factors linked to asthma in babies
Maternal obesity increases the risk of frequent wheezing in offspring
7 March 2013 10:40

The fact that excess weight during pregnancy has negative consequences is not new information. A new study now concludes that the children of mothers obese before falling pregnant are four times more likely to have frequent wheezing, which is one of the symptoms of asthma, compared to the children of mothers weighing a normal weight.

The most important epidemiological study to date on the matter
Physical activity does not protect against in situ breast cancer
27 February 2013 9:45

Non-invasive or in situ breast cancer is characterised by the fact that it does not invade or does not multiply in other cells and unlike invasive breast cancer, it is not benefited by physical exercise. The experts suggest that exercise would only have protective effects once the tumour starts to invade the breast tissue.

Since 1992 the number of deaths linked to breast cancer in Spain has decreased among young and middle aged patients but not among the elderly. Spanish researchers also predict that it will continue to decline over the next decade, although more slowly as observed up until now.
