Helping the Embryo Implant: A New Role for One Type of Immune Cell
piggy submitted, created time 3 days 13 hours (www.sciencedaily.com)
One of the most critical stages in establishing a pregnancy is the implantation of the embryo in the wall of the uterus. Although the accumulation of immune cells known as DCs has been observed in the uterus after fertilization and prior to implantation, their function was not known 
Gene testing of embryos needs guidance

Couples might soon use the technologies sold by personal-genomics companies to choose the genetic make-up of their children.
Antidepressant treatment may reduce male fertility
piggy submitted, created time 2 weeks 5 days (www.reuters.com)
Treatment with paroxetine (Paxil), which belongs to the selective serotonin reuptake inhibitor (SSRI) class of antidepressant drugs, increases DNA fragmentation in sperm, according to research presented today at the sixty-fourth annual meeting of the American Society for Reproductive Medicine in San Francisco.
Although the study did not directly evaluate male fertility, the fivefold increase in the number of men who developed abnormal sperm DNA while being treated with paroxetine is "troubling" and "suggests an adverse effect on fertility," co-investigator Dr
Republican presidential platform would ban all human embryonic research
Darkfrog submitted, created time 2 months 4 weeks (www.nature.com)
The Republican presidential platform proposes banning all human embryo research throughout the United States. Although John McCain himself has voted to loosen federal restrictions on stem cell funding, the party that supports him appears to be taking a more conservative line.
But for the grammar enthusiasts among us, the change in the platform was effected with one word. They canged "and" to "or," so that they call for a ban on the "the creation of or experimentation on human embryos for research purposes
Nature takes a look at in-vitro fertilization's past, present and future

This article is a comprehensive look at the past and future of artificial babymaking. It covers IVF, the possible use of iPS to make gametes. It covers ethics, public relations, and economics...
The part that I like best? IVF has "gone as far as it can" with regards to what it can do, so the next focus is on making it cheaper. The article discusses the woman in a developing country who, on top of her own wishes for a family, faces discrimination for her infertility

A group of Canadian and European researchers have unlocked the mystery of a gene with the potential to both regulate and block ovulation.
The new study - a collaboration between the Universite de Montreal in Canada and the Institut de Genetique et Biologie Moleculaire et Cellulaire of the Universite de Louis Pasteur, Strasbourg, France - is published in the latest issue of the journal Genes & Development.
"Our findings demonstrate that the Lrh1 gene is essential in regulating ovulation," said Bruce D
Size of a woman's uterus predicts whether she is at risk of having very premature twins after IVF

Using ultrasound to measure the height of a woman's uterus is a good way to predict whether or not she is at risk of having babies born prematurely if she becomes pregnant with twins after IVF, according to new research presented at the 24th annual meeting of the European Society of Human Reproduction and Embryology in Barcelona.

Harvesting stem cells at the four-cell stage can be easier and safer
Darkfrog submitted, created time 4 months 3 weeks (blog.wired.com)
Here is a Wired Science writeup of that article I posted yesterday. It's less detailed, but it's easier to read. Again, the top story is that researchers have found a new way to harvest stem cells from embryos without destroying them: taking a cell at the four-cell stage produces cell lines that don't need to be co-cultured. And we already know from fertility treatments that the remaining three cells can grow into healthy children.
Obesity Affects Sperm Production

This research presented Wednesday at a meeting of the European Society of Human Reproduction and Embryology, scientists found that obese men have worse sperm than normal-weight men
Predicting Success with in Vitro Fertilization

Researchers say they can predict with 70% accuracy whether women who have IVF will get pregnant.
July 1, 2008 -- We've come a long way since the first "test tube" baby was born in 1978. Now, researchers are looking at how to predict whether women will become pregnant from in vitro fertilization.
Researchers led by Stanford University Medical Center assistant professor of obstetrics and gynecology Mylene Yao, MD, found a 70% accuracy rate in predicting whether a woman who has undergone IVF will become pregnant
High-calorie diet linked to boys
kavin submitted, created time 7 months 1 week (news.bbc.co.uk)
Recently, the researchers in the Universities of Exeter and Oxford suggests a high-calorie diet at pregnant time--and regular breakfasts--might increase the odds of a boy. And the modern trend to opt for low calorie diets might explain why the proportion of boys is falling in developed countries.
The study, by the Universities of Exeter and Oxford, appears in the Royal Society journal Biological Sciences.
Sex is determined by appetite?

Eating breakfast cereal might make it more likely you have a boy. Is that really true? I bet most mothers would now take cereal for breakfast now after reading this article.
A drive to lower the incidence of multiple births in fertility treatments
Darkfrog submitted, created time 9 months 1 week (www.nytimes.com)
Doctors employing in vitro fertilization tend to implant several healthy embryos in the hopes that at least one will end up as a full-term healthy baby. However, this technique often leads to multiple births. Women carrying three or more children have a dramatically increased risk of health problems, premature birth and miscarriage, to the point where doctors often recommend "reducing," or selectively aborting one of the fetuses once it becomes apparent that triplets or more are on the way
When kissing cousins are good for kids

In Western societies, "kissing cousins" are mocked, reviled and sometimes outlawed. Oddly, however, a new study suggests that a little bit of inbreeding might be beneficial to the family line.
Further review of "three-parent" embryo technique
Darkfrog submitted, created time 9 months 3 weeks (www.nature.com)
This is another discussion of the mother-father-mitochondiadonor embryo that I mentioned the other day. It is significantly more revealing. It seems that the mitochondrial transfer involved moving nuclear DNA from the diseased embryo to the healthy one instead of into an ovum from another source.
It also discusses their methods. It seems that the exchange was performed in embryos that had failed in other experiments. The ten successes came from many failures. The specific success to failure ratio is not given.
