Afghan Women Fertility Decline Reflects Public Health Campaign and New Possibilities For Women

Fertility Rate Drops In Afghanistan, But Will It Continue?  by Haya El Nasser and Paul Overberg.  USA TODAY.  January 25, 2013.

In the 90's Afghan women could expect to have 8 children in a lifetime;  In the mid-2000s the number fell to 6.3;  At the end of end of the decade the number was 5.1.  The high number in the 90s reflected the policies of the Taliban, e.g. not allowing girls to go to school, endorsing the practice of child brides, and ignoring women's health care.  High fertility rates make reduction of poverty rate difficult.

Hidden Dangers of Obesity

Revealing the Unexpected Dangers of Obesity by Shirley S. Wang.  The Wall Street Journal.  October 29, 2012.

Obesity is a complex condition involving hormones, inflammatory molecules and chemicals that can have wide impact.  Just how wide is only now beginning to be understood.  For example, the olfactory bulb contains one of the densest collection of insulin receptors outside the pancreas.  In mice research, there are indications that the change in the sense of smell is related to obesity, either as a effect or as a cause.  Sleepiness, apart from sleep apnea, could also be related to obesity as perhaps is fertility and cancer.

Viable Eggs Created From Normal Cells

Japan Team Offers Fertility Hope with Stem Cell Eggs.  New York Daily News.  October 5, 2012.

Using mice, Japanese researchers have created viable eggs from normal cell.  Mice stem cells were harvested and genetically altered to create the primordial germ cells that create sperm and eggs. The cells were extracted, fertilized, and implanted into surrogate mother mice.  The mice pups born were healthy and able to reproduce.  With further research this type of approach could be beneficial for reproductive medicine in humans.
