Antidepressant treatment may reduce male fertility
piggy submitted, created time 1 week 2 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 
Testicles could provide "ethical" stem cells

This article provides more information about last week's announcement that researchers have found a form of adult stem cells that appear to be as versatile as embryonic cells ...in men's testicles.
A team out of the University of Tubingen in Germany managed to convert spermatagonial cells into skin, gut structures, cartilage, bone, muscle, and neurons, quite an accomplishment. Some of their colleagues are enthusiastic. Robert Lanza of Advanced Cell Technology in Massachusetts (U.S
Republican presidential platform would ban all human embryonic research
Darkfrog submitted, created time 2 months 2 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
Can you turn teeth into sperm?
sea-maid submitted, created time 4 months 5 days (www.newscientist.com)
COULD sacrificing a tooth enable some infertile men to father children? That's the goal of researchers in Brazil, who suggest that stem cells from human teeth can be coaxed into becoming sperm by being injected into the testes of mice.
Irina Kerkis of the Butantan Institute in São Paulo and her colleagues injected stem cells from the dental pulp of human teeth into the testes of live mice. The cells seemed to migrate to the tubules where sperm usually mature and differentiate into cells resembling human sperm
Size of a woman's uterus predicts whether she is at risk of having very premature twins after IVF
kavin submitted, created time 4 months 1 week (www.news-medical.net)
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 1 week (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

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
Toxicity is the question: Bisphenol-A on trial in Canada
Darkfrog submitted, created time 7 months 5 days (www.nytimes.com)
Bisphenol-a is a molecule found in many common rigid plastics. It also acts as an estrogen mimic in many different types of animals, including humans, causing or potentially causing lowered sperm count, increased risk of breask cancer, infertility in men and both toxic and neurotoxic effects. The Canadian government is preparing to label bisphenol-a as "toxic," and thereby forbidding it to be used in plastics that are meant to contain food or drink, such as baby bottles, water bottles and the linings of cans
A drive to lower the incidence of multiple births in fertility treatments
Darkfrog submitted, created time 9 months 2 days (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

Some parents use PGD to select for deafness, dwarfism
Darkfrog submitted, created time 11 months 3 weeks (www.nytimes.com)
I read this one a few months back, but it ties into what some of us were talking about over here on Eric's recommendation: http://discover8.com/article/Should_Fertilized_Eggs_Have_Rights__0#creplyto
It's basically an ethical pondering of parents who are deaf or dwarfs (achondroplasia et al) and use PGD and fertility treatments to deliberately select embryos that share the deficiencies that led to their adult phenotypes.
What I like about this one is that it focuses on whether or not the parents are right to do it AND whether or not the doctors are right to refuse.
Do frozen human ova remain viable? Different voices disagree.
Hecate submitted, created time 1 year 4 weeks (www.nature.com)
Scientists are debating whether the practice of freezing human ova should be considered experimental or whether it should be deemed standard. (This distinction, pedantic though it may seem, has some consequences for health insurance.) The debate covers not only the best method for freezing eggs (slow-freeze vs. fast, in layman's terms) but the circumstances under which it is appropriate to do so at all.
Many women choose to freeze their eggs because of illness. For example, some forms of radiation and chemotherapy can cause infertility
