Men who father children with multiple women are responsible for “extra” diversity on the X chromosome, a new study of six different populations suggests.

Flu shots given to pregnant women a month or more before delivery will prevent most cases of influenza during the first six months of their babies' lives, researchers said.
C-sections might affect a new mother's ability to bond

This is interesting. It's a New York Times writeup of a study in the Journal of Child Psychology and Psychiatry showing that women who deliver their children vaginally as opposed to by C-section are more responsive to the sound of infants crying a short time after the birth takes place.
There are some flaws in this study. First off, it only involved a small number of women, which increases the likelihood of statistical errors. Second, it does not show how whether this is a case of delayed attachment or stunted attachment. C-section moms might well catch up as time passes
Early pregnancy trauma boosts schizophrenia risk

Excessive stress is never a good thing, but new research suggests that children of women who suffered severe psychological stress during early pregnancy are more likely to develop schizophrenia. ...
Nature takes a look at in-vitro fertilization's past, present and future
Darkfrog submitted, created time 2 months 2 weeks (www.nature.com)
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

Women exposed to high levels of PCBs (polychlorinated biphenyls - a group of banned environmental pollutants) are less likely to give birth to male children.
A study published today in BioMed Central's open access journal Environmental Health found that among women from the San Francisco Bay Area, those exposed to higher levels of PCBs during the 50s and 60s, were significantly more likely to give birth to female children

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?

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 2 months 3 weeks (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 2 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
New insight into SIDS--can seratonin alone cause death?
sea-maid submitted, created time 3 months 1 day (www.nature.com)
Mouse model suggests serotonin might play a role in crib death. This research team created mice with unusually high levels of seratonin receptor 1a (Htr1a), a receptor that binds to seratonin, decreasing the free levels of the neurotransmitter. (In other words, a mouse with high levels of receptor 1a will seem like a mouse with low levels of seratonin, even though its ability to produce seratonin is unimpaired.) They found that the mice periodically went into "crisis" states during which their heart rates and body temperatures plummeted
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
"Gay genes" may be good for women
sea-maid submitted, created time 3 months 2 weeks (sciencenow.sciencemag.org)
As gay couples race to the altar in California this week, scientists may have found an answer to the so-called gay paradox. Studies suggest that homosexuality is at least partly genetic. And although homosexuals have far fewer children than heterosexuals, so-called gay genes apparently survive in the population. A new study bolsters support for an intriguing idea: These same genes may increase fertility in women.
