The proportion of women infected with HIV has been on the rise for a decade; in sub-Saharan Africa, women constitute 60 percent of people living with disease. While preventative drugs exist, they have often proven ineffective, especially in light of financial and cultural barriers in developing nations.

New book on evolution and future of human reproduction

Human beings would probably be known as pilosals rather than mammals if Carl Linnaeus had not been a proponent of breast-feeding. For social and political reasons, the famed taxonomist labeled the class of animals to which humans belong with a reference to their practice of suckling their young rather than to their evolutionarily older characteristic of having hair.

Animal model of HIV sexual transmission

Infection by human immunodeficiency virus (HIV) causes acquired immunodeficiency syndrome (AIDS), a debilitating disorder in which progressive weakening of the immune system makes affected individuals more susceptible to potentially life-threatening infections and chronic diseases. Despite advances in the treatment and management of AIDS, there is no cure, and HIV infection remains a major global health problem.

Quality of life of young, female cancer survivors is impaired after treatment

A new study led by a University of Colorado Cancer Center member recently published in the journal Quality of Life Research reveals that in young, female cancer survivors, quality of life is significantly impaired long after treatment. The study compared 59 cancer survivors to 66 healthy controls and found that, as expected, cancer survivors showed higher stress and anxiety than the general population.

Protein in liver plays a crucial role in mice's pregnancy and human menstrual cycle

A protein first shown to function in the liver plays a crucial role in pregnancy in mice and has a key role in the human menstrual cycle, according to researchers at the University of Montreal. Mice that were genetically engineered not to produce the liver receptor homolog-1 (Lrh-1) molecule were unable to create the uterine conditions necessary for establishing and sustaining pregnancy, resulting in the formation of defective placentas.

Research show potential link between psychological vulnerability and timing of menstrual cycle

Women at a particular stage in their monthly menstrual cycle may be more vulnerable to some of the psychological side-effects associated with stressful experiences, according to a study from UCL.

Research: Women's reproductive function may be tied to their immune status

New research indicates that women's reproductive function may be tied to their immune status. Previous studies have found this association in human males, but not females.

Hormones regulate sexual desire in women

Feeling frisky? If so, chances are greater your estrogen level -- and, perhaps, fertility -- are hitting their monthly peak. If not, you're more likely experiencing a profusion of desire-deadening progesterone, and the less fertile time in your cycle.

Breast pain more common among women with larger cup sizes

Women with larger cup sizes seem to be more susceptible, but childless women also seem to be more prone, and wearing a sports bra doesn't always help, finds the study, which publishes as London gears up for its annual international marathon tomorrow (Sunday April 21).

Researchers discover injectable protein to reverse symptoms of dangerous conditions

The creation of new blood vessels in the body, called "angiogenesis," is usually discussed in connection with healing wounds and tumors. But it's also an ongoing process in the female reproductive tract, where the growth and breaking of blood vessels is a normal part of the menstrual cycle. But abnormal growth of blood vessels can have painful consequences and resultant pathologies.

Women over 40 need to be vigilant about contraception even in perimenopause

Women reaching the age of 40 tend to be less vigilant about birth control because they think the risk of pregnancy is low - or that birth control can cause health problems - but a review of the evidence by a team that includes a Women & Infants Hospital of Rhode Island physician recently underscored the need to be vigilant about contraception even in perimenopause.

Johns Hopkins develops PapGene test to diagnose ovarian and endometrial cancers

Using cervical fluid obtained during routine Pap tests, scientists at the Johns Hopkins Kimmel Cancer Center have developed a test to detect ovarian and endometrial cancers. In a pilot study, the "PapGene" test, which relies on genomic sequencing of cancer-specific mutations, accurately detected all 24 (100 percent) endometrial cancers and nine of 22 (41 percent) ovarian cancers. Results of the experiments are published in the Jan. 9 issue of the journal Science Translational Medicine.
