Embryo :: Time-lapse recordings reveal why IVF embryos are more likely to develop into twins

Evidence gathered from time-lapse recordings of the formation of early embryos (blastocysts) in the laboratory has revealed why embryos created via IVF and undergoing extended culture are more likely to develop into twins than those created via natural conception. Furthermore, the research has shown that the culture in which the IVF embryos are formed is possibly responsible for the embryos dividing into twins.

Infertility :: Key to male infertility

A factor in immune cells regulates human semen and seems to determine whether a man will be fertile, according to a new study.

Fertility :: Survivors of rare ovarian cancer retain fertility, have positive relationships

Ovarian germ cell tumor patients treated with platinum-based chemotherapy and fertility-sparing surgery are likely to retain their menstrual function and reproductive ability, according to the largest and most comprehensive survey of survivors ever conducted.

Sperm :: Sperm abnormalities seen in male lupus patients

The prognosis for systemic lupus erythematosus (SLE), an autoimmune disease that mainly affects women in their reproductive years, has improved recently, prompting a shift toward improving quality of life. For men with SLE, concerns have been raised about their future fertility.

Gene :: Researchers find gene that spurs development of the epididymis

Human sperm cells travel up to 6 meters in their transit from testes to penis, and most of that journey occurs in the epididymis, a tightly coiled tube that primes the cells for their ultimate task: fertilization. In a PNAS paper released this week, researchers report that they have discovered a gene — and related mechanism — essential to the embryonic development of the epididymis.

Child Care :: Childhood cancer survivors at increased risk of severe health problems as adults

A substantial proportion of childhood cancer survivors experience serious health problems as young adults, particularly those who received radiation treatment, according to a study in the June 27 issue of JAMA, a theme issue on chronic diseases of children.

Infertility :: Infertile couples willing to donate unused embryos to stem cell research

In a survey of over a thousand patients who have created and frozen embryos as part of fertility treatment, 60 percent said they would be likely to donate unused embryos for stem cell research, according to a study led by researchers at Duke University Medical Center and Johns Hopkins University. The researchers published their findings online in the June 21, 2007 Science Express, the online component of the journal Science, and the study will be published in the journal?s July 6, 2007 print issue.

Embryo :: Donated embryos could result in more than 2000 embryonic stem cell lines

In a survey of more than one thousand infertility patients with frozen embryos, 60 percent of patients report that they are likely to donate their embryos to stem cell research, a level of donation that could result in roughly 2000 to 3000 new embryonic stem cell lines.

Healthy :: How birth weight affects adult health and success

Birth weight has significant and lasting effects, a new study finds. Weighing less than 5.5 pounds at birth increases the probability of dropping out of high school by one-third, reduces yearly earnings by about 15 percent and burdens people in their 30s and 40s with the health of someone who is 12 years older.
