The prevalence of many types of birth defects appears to differ by sex, with the majority of them being more prevalent among men,1 2 including orofacial cleft (cleft lip with or without cleft palate), urinary system (hypospadias, hydronephrosis) and gastrointestinal tract (diaphragmatic hernia).
A report released today by the Australian Institute of Health and Welfare (AIHW) presents information on 33 major birth defects and shows that for many conditions, more males than females were reported to have a congenital anomaly (59% versus 41%).
Birth defects generally were more prevalent among males than females. This male excess of defects also has been observed in other cohorts. Infant and childhood mortality rates were lower for affected males than for affected females (16% vs 20%).
Smoking, drinking alcohol, or taking certain drugs during pregnancy. Having certain medical conditions, such as being obese or having uncontrolled diabetes before and during pregnancy. Taking certain medications, such as isotretinoin (a drug used to treat severe acne). Having someone in your family with a birth defect.
Male baby pregnancies are more likely to result in complications, possibly because they grow faster in the womb and require more nutrients and oxygen than supplied by the mother through the placenta -- the temporary organ that attaches to the wall of the uterus during pregnancy to help the fetus grow and develop.
Paternal age increases the frequency of congenital diseases such as heart malformations as well as oral, palate and lip cleft. Moreover, mental disorders (autism, schizophrenia, bipolar disorder, low IQ level as well as ADHD) also occur more frequently in advanced father's age.
The key to the research is this: Male embryos and fetuses are known to be weaker.
The most common birth defects are: heart defects. cleft lip/palate. Down syndrome.
Researchers think that most birth defects are caused by a complex mix of factors, which can include: Genetics. One or more genes might have a change or mutation that prevents them from working properly. For example, this happens in Fragile X syndrome.
The battle of the sexes begins at birth, with newborn girls more strongly genetically programmed than boys to withstand acute infection. A new study shows newborn girls have an innate genetic advantage when it comes to potentially dangerous infections.
“In the early weeks, through to beyond six months, they smile less and cry more, are more irritable and demanding and show less emotional stability.” Dr Chilton adds that baby boys need more emotional support from their mother, and for a longer period than baby girls.
An ultrasound creates pictures of the baby. This test is usually completed around 18–20 weeks of pregnancy. The ultrasound is used to check the size of the baby and looks for birth defects or other problems with the baby.
About 1 in 33 babies (about 3 percent) is born with a birth defect in the United States each year. Some birth defects don't need treatment or can be treated easily. But other birth defects need quick treatment because they cause serious problems or even death.
Between 2010 and 2019, birth defects increased as a proportion of child mortality in the Region, from 6.2% to 9.2%, and in four countries, birth defects now contribute to more than 20% of under-five mortality.
Researchers have found that severe morning sickness (called hyperemesis gravidarum) is slightly more common in pregnancies where the baby is a girl, which could reflect the differences in hCG. There are plenty of other hormones at work in pregnancy, whatever the sex of the fetus.
The structure of the sperm does not affect the baby in terms of causing any defects physically or mentally. The only issue that can cause due to abnormal sperm morphology is that, depending upon the percentage and the density of abnormal sperms, the pregnancy can be delayed or not occur altogether.
February 3rd is the only day where no one in history has ever been born. Despite much scientific study, there is no explanation for this phenomena. Historically it has been referred to as "the empty day" or "nobody's birthday". The years range from late 1700s to the 2010s.
A growing body of research demonstrates that stress before and during pregnancy is associated with poor birth outcomes and subsequent poor health outcomes for children. supports research, programs and policies which address risk factors to prevent stress-related pregnancy complications.
In Australia, about 3 in 100 babies are born with a health condition. Birth differences, also known as congenital anomalies or birth defects, include any health condition that a baby is born with.
According to data collected by the Centers for Disease Control and Prevention (CDC) and the Social Security Administration (SSA), the rarest month to be born in is February, making Aquarius the rarest zodiac sign.
In general, major defects of the body and internal organs are more likely to occur between 3 to 12 embryo / fetal weeks. This is the same as 5 to 14 gestational weeks (weeks since the first day of your last period). This is also referred to as the first trimester.
However, when it comes to health, men are biologically weaker. Men are more likely to experience chronic health conditions earlier than women and have shorter lives. In almost all countries around the world, women outlive men.
Women athletes are known to be less strong and powerful than equally trained men [1], muscle strength of women indeed, is typically reported in the range of 40 to 75% of that of men [2]; women are also known to be less powerful than equally trained men.
In the womb boys grow faster than girls and are therefore at greater risk of becoming undernourished. Fetal undernutrition leads to small size at birth and cardiovascular disorders, including hypertension, in later life.
