Fertility in developing countries: words into action
For almost 30 years - since the world's first test-tube baby was born in July 1978 - the benefits of modern infertility treatments have been largely confined to couples in developed countries. There, we have seen more than 3 million babies born as a result of IVF and, in some countries, as many as 4 per cent of all babies born conceived by modern fertility techniques.

In birds, expecting to mate leads to higher fertilization rates
From an evolutionary perspective, the primary task of an organism is to pass along its genes to future generations. Such genetic transmission is usually assumed to be instinctive. However, a new study shows that species also learn to adapt to their surroundings in order to increase their “reproductive fitness”— the likelihood that they will successfully reproduce.

Fetal cell 'transplant' could be a hidden link between childbirth and reduced risk of breast cancer
PHILADELPHIA – Some benefits of motherhood are intangible, but one has been validated through biostatistical research: women who bear children have a reduced risk of developing breast cancer. In Seattle, Washington, researchers at the University of Washington and Fred Hutchinson Cancer Research Center believe they have identified a source of this protective effect: fetal cells “transplanted” to the mother before birth.

Primate sperm competition: speed matters
Researchers at UC San Diego and UC Irvine have found evidence that supports the theory that reproductive competition during the evolution of primate species has occurred at the level of sperm cell motility. In a paper published online by the Journal of the Royal Society Interface, a team led by Michael Berns, an adjunct professor of bioengineering at UCSD and a professor of biomedical engineering at the Beckman Laser Institute at UC Irvine, and UCSD Ph.D. candidate Jaclyn Nascimento reported that sperm cells from the more promiscuous chimpanzee and rhesus macaque species swim much faster and with much greater force than those of humans and gorillas, species where individual females mate primarily with only one male during a reproductive cycle.

New cell death pathway involved in sperm development
Heavy and bulky sperm would not be good swimmers. To trim down, sperm rely on cell death proteins called caspases, which facilitate the removal of unwanted cellular material and radically remodel these cells into their sleek, light shape. New research from scientists at the Howard Hughes Medical Institute and Rockefeller University has now uncovered a new pathway that regulates these killer proteins, yielding new knowledge about caspase function as well as insights into the causes of human infertility.
