Hot tubs hurt fertility, UCSF study shows
Exposure to hot baths or hot tubs can lead to male infertility, but the effects can sometimes be reversible, according to a new study led by a University of California, San Francisco urologist.   view more (2007-03-05)

Newly discovered proteins in seminal fluid may affect odds of producing offspring
Seminal fluid contains protein factors that, when transferred from a male to a female at mating, affect reproductive success. This is true of many different animals, from crickets to primates.   view more (2008-07-29)

A gas, Viagra and sex in plants - researchers at the Instituto Gulbenkian de Ci'™ncia have found a link
Viagra affects growth of the male sex organ of plants, by intensifying the effect of nitric oxide during plant fertilization. This discovery, made by the Plant Development team at the Instituto Gulbenkian de Ci'™ncia(IGC), in Portugal, will be published in Development, in June. The study, led by José Feij'³, takes a step further in... view more... (2004-05-11)

Two landmark fertility studies give hope to young male cancer patients
Research studies published today (Thursday 28 November) in Human Reproduction[1] bring new hope of preserving fertility for boys who face sterility after cancer treatment. In one study Japanese fertility experts report two world 'firsts' - mice born from frozen immature testicular tissue taken from one set of mice and matured in others, and a... view more...

For young boys with cancer, testicular tissue banking may be option to preserve fertility
For parents of children with cancer, the hopeful news is that pediatric survival rates have steadily improved for decades. Among the bad news-treatments that enable survival often cause infertility.   view more (2009-11-10)

Sea lamprey jettison one-fifth of their genome
Researchers have discovered that the sea lamprey, which emerged from jawless fish first appearing 500 million years ago, dramatically remodels its genome. Shortly after a fertilized lamprey egg divides into several cells, the growing embryo discards millions of units of its DNA.   view more (2009-07-21)

Stem cell chicken and egg debate moves to unlikely arena: the testes
Logic says it has to be the niche. As air and water preceded life, so the niche, that hospitable environment that shelters adult stem cells in many tissues and provides factors necessary to keep them young and vital, must have emerged before its stem cell dependents.   view more (2008-07-21)

Eggs from embryonic stem cells could benefit sterile women
Monash researchers have developed a process that causes embryonic stem (ES) cells to develop into ovarian structures containing eggs.    view more (2005-06-20)

New contraceptive device is designed to prevent sexual transmission of HIV
Researchers from Weill Cornell Medical College have published results showing that a new contraceptive device may also effectively block the transmission of the HIV virus.   view more (2009-05-20)

Cracking the egg
Sexual reproduction is not necessarily sexy (especially when scientists start analyzing it), but it is fascinating. As we all know, the basics entail bringing together an egg and a sperm, a whole lot of cell division and growth, and sooner or later a young organism that carries a mix of genes from both parents.   view more (2006-10-04)

Children born after PGD as healthy as those born after conventional IVF treatment
Children born after embryo biopsy for preimplantation genetic diagnosis (PGD) do not show any more major malformations than those born after artificial reproduction technologies (ART) without PGD.   view more (2007-06-18)

Technique may allow cancer patients to freeze eggs, preserving fertility before starting treatment
A new technique might allow women diagnosed with cancer the opportunity to have children when chemotherapy and radiation treatments rob them of their fertility, researchers at the University of Michigan Comprehensive Cancer Center have found.   view more (2005-05-29)

Scientists identify possible cause of endometriosis
Endometriosis is a condition whereby patches of the inner lining of the womb appear in parts of the body other than the womb cavity. It can cause severe pain and affects approximately 15% of women of reproductive age. Endometriosis is also associated with infertility, with 50% of infertile women affected by the condition.   view more (2008-08-06)

The latest about male infertility and testosterone from NewYork-Presbyterian/Weill Cornell
Two reports from physician-scientists at NewYork-Presbyterian Hospital/Weill Cornell Medical Center shed new light on male infertility.   view more (2007-10-18)

UVA studies potential target for skin cancer treatment
When normal skin cells become a melanoma tumor, they sometimes turn on genes not usually found in the skin.   view more (2006-10-04)

New research reveals unexpected post-mating gene expression in model lab insect
That cloud of tiny flies hovering around spoiled fruit isn't just a nuisance. In fact, what science calls Drosophila melanogaster is more and more the key to intricate genetic studies that shed light on numerous biological processes, especially reproduction.   view more (2006-06-28)

Heat therapy for cancer may be key to 'Lance Armstrong Effect'
Experts at Johns Hopkins have linked scientific evidence spanning more than 30 years to suggest an explanation for why testicular cancer patients like seven-time Tour de France winner Lance Armstrong survive far better than patients with other advanced cancers.   view more (2006-07-26)
