I decided to look up approximatley how many cigarettes a day causes what harm, since how much it harms the baby does matter on how much you smoke... I found this and thought this was kinda interesting. Its true, it was on an indiana news page.

Smoking may alter gender of developing fetus
��last updated: 2002-04-22 12:41:18-05

a study has found that smoking may do more than harm a developing fetus: it can also determine the gender of the baby.

Researchers recorded the smoking habits of more than 11,000 couples around the time of conception along with the sex of their child. The lowest ratio of boys was found in couples where both mother and father each smoked more than 20 cigarettes a day. The chance of having a boy was also reduced among couples where mom was a non-smoker, but dad smoked more than 20 cigarettes a day.
Researchers hypothesize that sperm cells carrying the y chromosome responsible for male children are more sensitive to unfavorable changes caused by smoking than sperm cells with an x chromosome and may be less likely to fertilize or may produce embryos that don't survive.
Researchers note that the number of boys born has dropped in the past few decades and say chronic exposure to toxins like cigarette smoke may play a role. They say the male chromosome and reproductive system are especially sensitive to such environmental toxins.
Researchers say they recorded a couple's smoking habits for the three months prior to conception. The study is published in the journal lancet and was conducted by researchers in denmark and japan.

Ratio of male to female children declines
the male to female ratio of children has declined substantially over the past few decades. The reason for this reduction is not clear, but it has been suggested that chronic exposure to toxic environmental agents that predominantly affect males and the male reproductive system could lead to a lower male to female birth ratio.

Fetal Alcohol Syndrome
Problem: fetal alcohol syndrome (.F.A.S) is a pattern of mental and physical defects which develops in some unborn babies when the mother drinks too much alcohol during pregnancy. A baby born with .F.A.S may be seriously handicapped and require a lifetime of special care. Some babies with alcohol-related birth defects, including smaller body size, lower birth weight, and other impairments, do not have all of the classic .F.A.S symptoms. These symptoms are sometimes referred to as fetal alcohol effects (.F.A.E). Researchers do not all agree on the precise distinctions between .F.A.S and .F.A.E cases.

Cause of the problem: alcohol in a pregnant woman's bloodstream circulates to the fetus by crossing the placenta. There, the alcohol interferes with the ability of the fetus to receive sufficient oxygen and nourishment for normal cell development in the brain and other body organs.

Possible .F.A.S symptoms:

* growth deficiencies: small body size and weight, slower than normal development and failure to catch up.
* skeletal deformities: deformed ribs and sternum; curved spine; hip dislocations; bent, fused, webbed, or missing fingers or toes; limited movement of joints; small head.
* facial abnormalities: small eye openings; skin webbing between eyes and base of nose; drooping eyelids; nearsightedness; failure of eyes to move in same direction; short upturned nose; sunken nasal bridge; flat or absent groove between nose and upper lip; thin upper lip; opening in roof of mouth; small jaw; low-set or poorly formed ears.
* organ deformities: heart defects; heart murmurs; genital malformations; kidney and urinary defects.
* central nervous system handicaps: small brain; faulty arrangement of brain cells and connective tissue; mental retardation -- usually mild to moderate but occasionally severe; learning disabilities; short attention span; irritability in infancy; hyperactivity in childhood; poor body, hand, and finger coordination.

Size of the problem: the incidence (number of new cases each year) of .F.A.S and .F.A.E are significantly under-reported. Therefore, projections are usually based on estimates of their occurrence per 1,000 live births. Recent studies by researchers ernest abel and robert sokol suggest that the incidence of .F.A.S can conservatively be estimated at 0.33 cases per 1,000 live births. Missouri recorded 78,468 live births in 1991 and 76,005 in 1992, which would yield at least 25 new cases of .F.A.S per year. The incidence of .F.A.E is generally regarded to be several times the magnitude of .F.A.S cases, perhaps in the hundreds in missouri.

Recommendations: studies suggest that drinking a large amount of alcohol at any one time may be more dangerous to the fetus than drinking small amounts more frequently. The fetus is most vulnerable to various types of injuries depending on the stage of development in which alcohol is encountered. A safe amount of drinking during pregnancy has not been determined, and all major authorities agree that women should not drink at all during pregnancy. Unfortunately, women sometimes wait until a pregnancy is confirmed before they stop drinking. By then, the embryo/fetus has gone through several weeks of critical development, a period during which exposure to alcohol can be very damaging. Therefore, the division of alcohol and drug abuse urges women who are pregnant or anticipating a pregnancy to abstain from drinking alcoholic beverages.

Here ya go:

Quote:

women who take the drug ecstasy in their first trimester of pregnancy may be putting their unborn child at risk for brain damage, according to a study published in the september issue of the journal neurotoxicity and teratology.

Jack w. Lipton, phd, a neuroscientist at rush-presbyterian-st. Luke's medical center in chicago, demonstrated that fetal exposure in rats to the drug ecstasy during a period analogous to the first trimester in humans causes changes in the young rat's brain chemistry and behavior. The study was funded in part by the national institute on drug abuse (nida). Ecstasy also is known as mdma or 3,4-methylenedioxymethamphetamine.

"the limited data that exist suggest that women who use ecstasy stop taking it when they learn they are pregnant," says Dr. Nora d. Volkow, director of the nida. "but many of the animal studies that linked this drug to neurological changes and learning impairments were conducted in situations analogous to the third trimester in humans. Thus, this study sought to investigate a more true-to-life situation by looking at neurobiological changes caused by ecstasy early in pregnancy."

lipton and his colleagues also found that behavioral changes were evident as well. When 21-day-old rats exposed to ecstasy in the womb were placed in a new environment away from their littermates, they spent significantly more time exploring and did not habituate as easily to the new environment. Such findings suggest that the ecstasy exposed rats may have learning or attention deficits or alterations in their anxiety levels. Another possibility is that they are simply hyperactive as a result of their in utero exposure.

"our findings show that exposing rats to ecstasy at a time of prenatal development that correlates with the first trimester in humans results in lasting changes in brain chemistry and behavior," notes lipton. "this research warrants the continued monitoring of children exposed to this drug."

My moms doctor told her it was actually healthy for her to have a glass of wine every so often while in her 3rd trimester? Is that true?

It's relaxing. I've had a total of three glasses so far during my whole pregnancy. Three glasses in 25 weeks, and I talk freely about this with my doctor.

Better safe than sorry! I drank before I knew I was pregnant, but not a sip since!

I can definitely respect the hell out of that. I'm just so glad I managed to quit smoking.

I hear before that the men's sperm can cause fas too! It the guy drinks and then get's someone pregnant it can also cause fas. You know what's crazy! When I worked as a waiter the lady that trained us to serve alcohol said that it's okay for a women to drink alcohol as long as it was reasonable. I was like in shock! I mean I don't think it's that bad as long as it's in your third trimester, but I could never do it and I would never encourage it.

Each glass of wine I had took a few hours to drink. I'm going to research the fas if I guy's drunk when he gets you pregnant. I think if that were true, you'd see a lot more babies with fas.

Fetal alcohol syndrome develops as a result of the baby receiving alcohol directly from the mother's blood through the placenta. When conception occurs, it doesn't matter how much alcohol the man drinks, there will not be alcohol inside his sperm cells. The baby has to have the alcohol in its bloodstream to get the syndrome, and it doesn't even have a bloodstream at birth.

Quote:
the royal college of obstetricians and gynaecologists recently conducted a large study including 400,000 american women, all of whom had consumed alcohol during pregnancy. Not a single case of fetal alcohol syndrome occurred and no adverse effects on children were found when consumption was under 8.5 drinks per week.

A recent review of research studies found that fetal alcohol syndrome only occurs among alcoholics. The evidence is clear that there is no apparent risk to a child when the pregnant woman consumes no more than one drink per day.

A study of moderate drinking during pregnancy found no negative effects. The researchers suggested that one drink per day provides a significant margin of safety, although they did not encourage drinking during pregnancy.

A study of pregnancies in eight european countries found that consuming no more than one drink per day did not appear to have any effect on fetal growth. A follow-up of children at 18 months of age found that those from women who drank during pregnancy, even two drinks per day, scored higher in several areas of development.

A recent analysis of seven major medical research studies involving over 130,000 pregnancies suggests that consuming two to 14 drinks per week does not increase the risk of giving birth to a child with either malformations or fetal alcohol syndrome.

Negative effects appear to be related to relatively higher levels of consumption per occasion, and hence, to higher blood alcohol content levels. Thus, it appears to be very important never to consume more than one drink in any one day while pregnant.

Seal/logo for royal college of obstetricians and gynaecologists the guidelines of the royal college of obstetricians and gynaecologists recommend that "women should be careful about alcohol consumption in pregnancy and limit this to no more than one standard drink per day." 9 these conclusions appear consistent with the research findings of the institute of medicine of the national academy of sciences, a major science body in the u.S.

The american college of obstreticians and gynecologists concludes that "there is no evidence that an occasional drink is harmful. Women who drink heavily throughout pregnancy may have smaller babies with physical and mental handicaps, but women who drink moderately may have babies with no more problems than those women who drink rarely or not at all.

I just got done reading about how fetal alcohol syndrome has become a moral panic. I think it really is a huge moral issue and I think women who drink excessively during pregnancy are disgusting. I'm fine with my occasional glass of wine during my bubbe bath. I might as well treat myself like a queen during my pregnancy every once in a while, no one else is. Wink

Maybe the research I did in highschool was wrong. I had to do a presentation on fas once and somewhere off the internet we found a article about the men contribiting to it. However, that was like over five years ago so things have changed too.
